1 Graphical NC Programming (Operating)

1.1 Basic Information

General Information Regarding Graphic NC ProgrammingGraphical NC Programming (GNP) is an effective means for NCworkpiece programming. It allows the user to define geometric elements,such as contours, without the help of external software. The definitionalso includes editing or machining of these contours for turning andmilling in the 2½ D range. Programmers are supported by extensivedialogs with graphics. The resulting traversing instructions are an integralpart of the NC program.

The availability of these graphics-based dialogs depends on the licensesacquired for GNP software options.

Note: The present main chapter is primarily intended for applicationswhich are provided with graphics-based dialogs, i.e. shop floorprogramming.

Using cycles (GNP cycles), the GNP internally generates an NC code inthe DIN and CPL syntax defined for the MTX (see Rexroth IndraMotionMTX Programming Manual DOK-MTX***-NC**PRO*V02-AW01-EN-P).

CAUTION

⇒ Since the number of possible combinations ofgeometry and machining variance is very great, theNC programmer has to take the necessary carewhen he checks and incorporates the results. Arecommended tool for this check is the NCsimulation.

The GNP is an optional part of the Rexroth IndraMotion MTX CNCcontrol. The licenses for the individual parts of the GNP are applicable tothe machining methods and to two versions each. The combination ofmachining method and version result in four software options and, thus,four licenses.

The following machining methods are covered:

• Turning (including center drilling) and

• milling/drilling(including driven tools in case of turning machines)

As regards the versions, there are the following options:

• Basic package: Programming is possible only for a limited number ofGNP cycles of the machining technology concerned. Programming iscarried out directly in the NC Program Editor, exclusivley without userguide in the form of dialogs and without graphic support.

• Additional shop floor programming package: It is possible to use theentire scope of GNP cycles assigned to the machining methodconcerned. In addition to the NC Program Editor, convenient dialogswith graphic support are also available. The additional package canonly be acquired if the basic package for the machining technologyconcerned is already available.

performance scope

(*) No graphical supported dialogs exist for this cycles in the versionMTX02VRS. These are in the preparation phase and will be madeavailable in a future release within the technology package milling - shopfloor programming.

RequirementsWorking with GNP requires one or more valid licenses. This involves boththe graphics-based input dialogs and the compilers mentioned below.

The software options acquired are activated by the Bosch RexrothService.

The GNP can only be used if the minimum channel and/or machine toolrequirements are met. The channel used by the GNP must be providedwith at least two synchronous NC axes in the basic channel position, withthese axes allowing turning and/or milling cycles. These axes spread theso-called default DCS (Description Coordinate System), the defaultdescription coordinate system for contours and cycles.

All GNP functions are available only when filenames have the “.npg”extension, i.e. for NC programs only.

Every NC program with GNP cycles is adjusted to comply with theconditions in a specific channel. To this end, there are a number of GNPoptions which are defined with reference to a specific channel(settings/adjustments).

Within the scope of the GNP, an NC program without channelidentification is automatically assigned to channel 1. If it is intended to runthe program in a different channel, a channel identification code must beadded to the first Line program line (see Rexroth IndraMotion MTXProgramming Manual DOK-MTX***-NC**PRO*V02-AW01-EN-P, Section"Channel Identification").

Any editing steps in the GNP dialogs and compiling actions are alwayscarried out for the channel assigned to the NC program according to therule above, irrespective of the channel currently active on the userinterface.

The compiler serves to generate a sequence of DIN and CPL blocks fromthe GNP cycles. An NC program which contains GNP cycles must first becompiled before it can be selected for processing on the CNC.

To achieve this, the program to be compiled must be selected from the“Program” operating area of the Navigator. Click on <F8>"NC ProgramFunctions" and then on <F3>"Compiler". Information on the progress ofthe compiling process is displayed in the status bar.

It is also possible to compile the main program implicitly on programselection.

If the compiler emits error and warning messages, a message will bedisplayed. Compiling can be interrupted at any time with the Escape key.

Note: Whenever it has been altered, the NC program must be re-compiled. If this requirement is neglected, the appropriateCNC error message is generated during runtime or onprogram selection.

Compiling is carried out automatically only after the "Active NCprogram" function has been altered (correction of the activeNC program.

Re-compiling is also required after GNP options have beenaltered and in case of relevant changes to the machineconfiguration (MACODA).

Operation of the compiler is not recursive.

Note: Any subprograms called by the compiled program must becompiled separately with GNP instructions.

If relevant configuration data is changed (MACODA), if descriptioncoordinate systems other than the default DCS are used, of if there arespecial conditions in the channel, then the appropriate adjustments mustbe made via the GNP Options dialog ("GNP Options", S.1-8).

Methods of Collecting GNP InstructionsGNP instructions can be collected either by editing single characters inthe NC Editor or by means of an input or edit dialog.

GNP instructions are collected or corrected according to the syntaxrequired and by means of the NC Editor. This type of collection is possiblewith any combination of available GNP software options.

GNP dialogs are called from the NC Editor. Graphics and dialog elementsare displayed over the NC Editor. Graphics-based dialogs are availableonly if at least one license of the "shop floor programming" version hasbeen acquired.

Grouping of GNP InstructionsGNP instructions are assigned to two main groups:

Geometry definitions determine the location of machining (contours,form elements, manipulations, point sets) and always have a definingcharacter only in the NC program. In other words, these instructions donot alter the NC program and do not trigger any motion of the CNC. Theydo not have any effect similar to that of a comment. The actual machiningsequence will only result in connection with a cycle. Geometry definitionscan be defined at any point of the NC program, irrespective of the context,but they must always be defined before they are used in a cycle or othergeometry definitions.

The GNP instructions on geometry definitions are once again subdividedas follows:

• Header and end instructions for contour and point set definitions;

• contour element instruction (lines, arcs, and transition elements, withthe sequence forming a train of contour elements)

• form element (schematic contour definition, mostly consisting ofseveral contour elements, e.g. rectangular pocket);

• manipulation instructions (turning, moving, mirroring and mergingpredefined contours and point sets);

• Point set instruction (drilling positions).

GNP cycles are technology subprograms (e.g. call of a rough-cuttingcycle along a contour) used to implement the actual machining process.Most of the cycles refer to an existing geometry definition. The completesequence of motions at the NC machine will not be initiated until the cycleis called.

1.2 Fundamental Information on Operation and Layout of theGNP Dialogs

Editing Actions

Inserting a New GNP Instruction

Note: GNP dialogs can be used only after the NC program has beenopened with the NC Editor beforehand.

To insert new instructions, place the cursor on that line in the partsprogram that follows the position where you wish to add the newinstruction. Then click on <F5> "Insert…". On the new F-key level thatwill be displayed thereafter, select either <F4> "GNP Contour" or <F5>"GNP Cycle" according to the desired group of instructions.

Then the NC Editor switches to the graphic view mode. Enter theappropriate instruction in the dialog and exit the graphic view of GNPinstructions by clicking <F9> "Apply" or <F8> "Cancel".

After the system has returned to the NC program view, the new content isadded in front of the current line position of the cursor.

Correcting a GNP InstructionTo correct a GNP instruction, place the cursor on the line to be edited. Ifcontours consisting of a sequence of contour elements are concerned,select any line of the contour description. Then select the contour elementto be corrected from the graphics. Use <F8> "GNP Correction" to makethe dialog-based correction. Correct the appropriate instruction in thedialog and exit the graphic view by clicking <F9> "Apply" or <F8>"Cancel" (discard).

After "Apply" has returned the system to the NC program view, theinstruction to be corrected is replaced by the content edited.

Deleting a GNP InstructionUsually, GNP instructions are deleted in the NC Editor. Please note thatgeometry definitions (contours, form elements, …) still having referenceto a cycle or a contour manipulation may only be deleted if all instructionshaving reference to the contour to be deleted are also deleted. Otherwise,an error will be generated when you continue work with the GNP dialogsat a later point or when you are compiling.

The dialog for the geometry definition provides additional delete functionsfor contour elements and entire contours.

Screen StructureThe basic structure of the screen of the GNP dialog is as follows:

GNPU_ScreenLayout_gr.bmp

(1): Header(2): Title bar (hidden by default)(3): Menu bar (hidden by default)(4): Graphic window(5): Dialog area(6): Help graphic(7): Entry fields(8): Selection menu(9): Desktop status bar(10): M keys(11): F-keys(12): OP-keys

Fig. 1-2: Simulation screen structure

The graphic window is that area of the display where the inputs withregard to geometry definitions and machining parameters are visible.

Depending on the current conditions, the graphic can contain theelements listed below. Separate colors are assigned to each element.

• Axis scales with axis name

• Grid (facilitates reading of coordinates)

• Geometry definitions (with separate colors for selected and non-selected definitions)

• Design help lines

• Tool path for active motions (complete line)

Graphic window

Graphic elements

• Tool path for rapid traverse motions (broken line)

• Hatching of the surface that has been end-milled (set of circles withtool diameter)

• Tool (symbolic).

The dialog area provides branches via selection menus and input masksfor parameter values, supported by an auxiliary graphic. The branchesthat start from a selection menu either open a new selection menu or aninput mask with an auxiliary screen or they open a modal dialog.

The status bar provides information on the current cursor coordinates, thecurrent edit mode, i.e. insertion or correction, and instructions onoperation.

The assignment of the F-keys will be described in connection with theoperator steps for selected examples on pages 1-15 ff. For generalsituation-spanning operating actions like operating the graphics and theoptions, see the following sequences ("Operating the Graphic", S. 1-7 and"GNP Options", S. 1-8).

Operating the Graphic

ZoomZooming is only possible with F-keys. On cycle input, the associated keysare on the first level. On contour input, they are accessible only after <F7>"Zoom/Options" has been clicked ("Zoom menu/Options").

<F3> "Zoom Window" is available for contour definition only. This keychanges the cursor type for the definition of an image detail (rectangularcursor). This cursor type is always available on cycle input.

The function which defines an image detail used for zooming-in can onlybe executed with the mouse. Place the cursor on that corner of theimaginary rectangle which should form the limits the new image detail.While holding the left mouse button, drag the cursor to the oppositecorner of the image detail. Release the mouse button. The magnifiedimage detail will be displayed.

<F4> "Zoom +" magnifies the current image centrically.

<F5> "Zoom -" reduces the current image centrically.

<F6> "Zoom out" restores the original non-magnified image. On cycleinput, this is an image detail which displays the entire graphic in full-screen size. On contour input, there are two conditions which can betoggled by repeatedly clicking on <F6>: the full-screen representation ofthat part of the contour that has been defined so far and the image detailthat encloses the window coordinates of the current DCS in full-screensize.

MovingPress the <ALT> and <cursor keys> to move the graphic up, down, tothe left and to the right.

The contour definition function also enables the graphic to be moved withthe mouse. The associated F-keys are accessible on a second F-keylevel only after <F7> "Zoom/Options" has been clicked ("Zoommenu/Options").

Click <F8> "Drag mode on/off" to activate the cursor type required formoving (four arrows arranged in the form of a cross). While holding theleft mouse button, you can now move the graphic as desired.

GNP Options

General InformationThe Options function allows to make presettings for graphic colors,technological default settings, axis assignments, etc. As a result,reasonable customer-specific and channel-specific presettings canalready be made for many dialogs. The majority of this preset data is notapplied to the NC program as parameters. This provides a betterclearness and reduces the data volume of the NC program.

CAUTION

⇒ Please note that any changed Options settings mayhave an effect on all NC program, i.e. includingexisting ones. In other words, "safety-relevant"settings (e.g. tool change variant, tool radiuses,cutting variant) may only be made with all NCprograms taken into account.

You can call up Options in the NC Program Editor from the <F4> "GNPcontour" or <F5> "GNP cycle" or <F8> "GNP correction" functions.The <F7> "Options" function is available on a further F-key levels.

The dialog provides several tabs each grouping related settings.

• DCS (description coordinate systems)

• Colors

• Turning (turning technology)

• Turning oversize (supplementary specifications for turning technology)

• Milling/drilling (milling and drilling technology, in preparation)

• Tools (specifications for tools and tool test)

Five operator buttons are provided at the bottom of the tabs which havethe same effect on all of the tabs.

Applies all current settings and closes the dialog.

"Cancel" or <ESC> discards all settings made since the Options dialoghas been opened or all settings that have been made since the last timethe "Apply" button was used. The dialog is closed.

DCS TabThe DCS tab allows to define, edit and delete description coordinatesystems. A description coordinate system is only applicable to thechannel under consideration ("Requirements", p. 1-3).

GNPU_OptionDCS_gr.bmp

Fig. 1-4: Description coordinate systems DCS

The "Designation" field provides a list containing all names of the DCSalready defined. You can select the DCS with the cursor keys or themouse. The fields and buttons described below will refer to that particularDCS. The "Standard" option shows the name of the default DCS. Thedefault DCS is derived from the configuration parameters and can,therefore, be edited only within certain limits. The default DCS is assignedto those geometries which do not contain any DCS declaration in thecycle head.

The "NC Code" field displays the declaration of the DCS currentlyselected. This declaration according to the DIN code is used to identifythe DCS, e.g. if it is mentioned in a contour definition.

Click the "New" button to create a new DCS before the current cursorposition in the "Designation" list. This opens a dialog where you shouldenter the designation. Initially, the declaration of the default DCS isassigned to the new DCS. Then change the declaration with the "NCCode" function.

The "Designation" function permits to change the name of a DCS at anytime (rename). Apart from the display function, the designation does nothave any further meaning.

Designation



Click the "NC Code" button to change the declaration of a DCS. Thedeclaration has a considerable effect on the definition of geometries andcomprises the following definitions:

• Diameter/radius programming

• Interpolation level

• Two to three axis names (to be entered with reference to the axisfunctionality; the axis perpendicular to the interpolation plane may bemissing)

• Cylinder coordinate transformation (involute) yes/no.

The declaration of the default DCS must not be changed, with theexceptoin of the axis designations. If logic axis designations are availablein addition to physical axis designations, then either can be used.

GNPU_OptionDCSCode_gr.bmp

Fig. 1-5: Entering the NC code (DCS declaration)

If you click on "Selection/Deselection of transformation" button, anadditional dialog will be opened, where you can file NC block sequencesof any contents for activation and deactivation of the DCS. This option isparticularly provided for activating and deactivating transformations, as ithas been taken into account in the submission of proposals (keyfunctions). Please take note of the wildcard "%RI%" which stands for thecurrent reference radius. If you do not file the block sequences forselecting and deselecting the transformation, you will have to manuallyprogram the appropriate sequences yourself before and after the cycle.

The "View" function allows you to enter the window coordinates tobecome effective in the contour dialog on "zooming out" in the imagedimensions.

Clicking the "Delete" button will remove a DCS after a safety prompt. Thedefault DCS does not provide this function.

Turning TabThis tab allows you to set default data for turning cycles. Most of thesesettings exist as cycle parameters. The settings you make here will beprovided as presettings when you call up the GNP cycle dialog. Valuesnot edited in the dialog are not applicable as parameters in the cycle.

Some of the settings are no cycle parameters, but do still have an effectin the cycles. You can change these settings only on this tab (e.g. tooledge radius correction).

Turn Oversize TabThis tab is assigned to the turning technology. These settings areintended to exclude short contour elements (lines only) from beingsubjected to an oversize. These contour elements whose length does notexceed the particularly specified numeric value are always turned to theirfinal size, irrespective of the contour oversizes that have beenprogrammed. For example, this is often desired in case of undercuts.Enter the values separately for vertical and plane surfaces and forascending contour sections and undercuts.

Tools TabThe "Tools" tab provides presettings for tool data. These are the tool edgeradiuses for the contour turning and grooving cycles. On being called, theGNP cycle dialog provides these radiuses. If it remains unchanged, theradius preset in the dialog will not appear as cycle parameter. Thefollowing assignment applies:

• TR in the standard tool edge radius plunging cycles (G720, G721,G722).

• TR2 is in the standard tool radius for all contour turning cycles (G710,G711).

All other settings in this dialog (tolerance, tool addressing) are not usedpresently. Their assignment is irrelevant.

1.3 Geometry Definitions

Inserting a New Contour (Train of Contour Elements)

Example Contour

Note: Since geometric problems are manifold, examples will be usedbelow to illustrate the operator steps required for defining thetool geometry.

GNPU_ContourSample_gr.bmp

Fig. 1-9: Example contour of a turned part

Calling the Contour Definition and Assigning it to aDescription Coordinate System (DCS)To insert a new contour definition, position the cursor on that line in theparts program (in the NC Program Editor) that follows the position whereyou wish to insert the new contour, e.g.

G96 S1=270 M104

G0 G18 X200 ; cursor position

Click <F5> "Insert…" and, thereafter, on the new F-key level that opens,click on <F4> "GNP contour".

If the GNP configuration provides several description coordinate systems(DCS), you can select the DCS desired by clicking on the F-key <F4>"Next DCS". For example, this is necessary for turning machines withdriven tools, where either a turning contour definition or a milling contourdefinition (end face/jacket face) can be selected. This is visually indicatedby the axis names next to the coordinate system and the DCS name thatis shown to the upper right. At the same time, all geometry elements(contours/form elements) that have been programmed previously andthat are assigned to the particular description coordinate system indicatedare displayed.

For the example, select a DCS with the axis names Z and X; specify X inits diameter (diameter symbol at the vertical axis).

Then the F-key level moves to the "Menu following element". The lastcontour entered will remain visible for information purposes until you haveselected the next element or a correction is necessary. This F-key levelprovides the following additional functions:

Click <F3> "Correction" to enter the correction mode. The correctionmode provides the possibility of correcting any element of the contour orof subsequently inserting and/or deleting transitional elements (chamfers,roundings, undercuts).

Click <F4> "Append Straight Line" to define addition of a straight line(line) after the last contour element.

Click <F5> "Append Circle" to define addition of a circle (circular arc) afterthe last contour element.

Click <F6> "Append Transition" to define transitional elements (chamfers,rounding radiuses, undercuts). This function is not available immediatelyafter the starting point; therefore, it is disabled.

Since the next element in the example is a straight line (line), click <F4>"Append straight line" to move to the function of defining straight lines.

Following Element: Straight Line 1After you have called the straight line definition function, the next F-keylevel "Menue course of straight line" is opened. This menu provides thefollowing F-keys.

<F3> "LIN (inclined)" defines that the straight line may extend in anydirection desired.

<F4> "LIN TG (inclined)" defines that the straight line follows at the end ofthe preceding element in tangential direction. This function is disabledsince a tangential direction is not or cannot be determined immediatelyafter the starting point.

<F5> "LIN (axially parallel vertical) defines that the straight line extends inparallel to the vertical axis.

Correcting Contour ElementsThe contour creation function provides the possibility of correcting contourelements that have already been defined. The correction, however, refersonly to the existing "design rule". That means that, if a circle comprisingradius and X-end point has been defined, only these values can bechanged. If not, the elements including the incorrect element must bedeleted element by element. In contrast to that, transitional elements(chamfers, roundings, undercuts) can not only be corrected, but alsoadded between two elements or deleted.

Start correction by clicking on <F3> "Correction" in the "Menu followingelement". The dialog moves from the insertion to the correction mode.This is also indicated in the status bar ("CORR").

The next F-key level, "Correction Menu", provides the following functions.

Click <F3> "Delete Element" to remove the contour element currentlyselected. This function is available for the last contour element and for alltransitional elements.

Click <F4> "Next Element" to navigate towards the end of the contour andto the following contour element. This is then displayed in a selectioncolor, and all of its determinants are displayed or provided for editing.

Click <F5> "Previous Element" to select the following contour elementthat is positioned towards the starting point of the contour for correction.

Click <F6> "Append Transition" to add a transitional element (rounding,chamfer, undercut) after the contour element selected. This function isnot available if a transitional element has already been defined at thispoint.

Click <F8> "Delete Contour" to delete the entire contour after confirmationof a safety prompt and return to the NC Program Editor.

Example 1:

The angle of the first straight line in the example program is to bechanged from 125 degrees to 125.1 degrees.

Click <F5> "Previous Element" until you have selected the straight lineto be edited and the associated input values are displayed. Then changethe value from 125 to 125.1 and confirm with <ENTER>. Then you canmake other corrections.

Since a geometry must be defined in the DCS for the majority of cycles, itis in many cases necessary to select the DCS first and then the cycle. Asa matter of principle, these steps can also be carried out in the reverseorder, provided that the button for the cycle to be inserted is enabled inthe non-desired DCS.

Note: Cycles not refering to a geometry definition include only a fewturning cycles (e.g. center drilling). Where these cycles areconcerned, all geometric definitions are transfered viaparameters. These cycles can only be used in the defaultDCS.

2.1 Geometry Definitions

Basic Information on Geometry Definitions

General InformationGeometry definitions determine the location and, in the most cases, alsothe final form of machining processes. These are two-dimensionaldescriptions of contours and drilling positions (points sets) which, bythemselves, do not trigger motions on the CNC. They do not have anyeffect in the program similar to that of a comment.

The motional sequence only develops in conjunction with a GNP cyclethat has reference to a geometry definition. To achieve this, an ident ornumeric ID that is unique in the entire NC program is assigned to eachgeometry definition. The reference of the GNP cycles to a geometrydefinition permits to reuse a geometry definition in cycles as often asdesired for various machining steps (e.g. rough-cutting and finish-cutting).

There are two main groups of GNP instructions:

• Geometry definitions, and

• GNP cycles.

A geometry can be defined at any point in the NC program. The definitionis independent of the context in the program. But it must be noted that thedefinition must always be placed at a position preceding its first utilization.

Geometry definitions are multi-line instructions. They always consist of

• a header instruction,

• one or more geometric elements, and

• an end instruction.

This order must be kept in the NC program. It must not be disturbed byDIN and CPL instructions. Comments must be avoided in a geometrydefinition.

There are two geometry header instructions:

• CONT for contour definitions, and

• PATT for point set definitions.

The header information contains the unique ident of the definition, limitsthe possible sequence of geometric elements (contour or drilling position)and assigns the definition to a description coordinate system (DCS).

The geometric elements are the actual components of each definition.They are subdivided as follows:

• contour element instruction (lines, arcs, and transition elements, withthe sequence forming a train of contour elements),

• form element (schematic contour definition, mostly consisting ofseveral contour elements, e.g. rectangular pocket);

• manipulation instruction (turning, shifting, mirroring and mergingpredefined contours and point sets);

• Point set instruction (drilling positions).

The geometry definition is completed with an end instruction. In thismanner, header and end instructions form a "bracket" around thegeometric elements.

• END_CONT - end of a contour

• END_PATT - end of a point set definition

The GNP instructions are based on a high-level language syntax. Theyconsist of

• function names (no long and short forms),

• opening round bracket for parameter list,

• parameter list (parameter address followed by its value, with severalparameters being separated by a comma), and

• closing round bracket.

If parameter lists are empty, the brackets are not necessary.

Note: In this manual, we mark optional parameters with curlybrackets. In contrast, the obligatory parameter is displayedwithout curly brackets.Wildcards for the values to be programmed will be identifiedby angle brackets. Curly and angle brackets are notprogrammed.

Example: FKT (PA<pa> {, PB<pb>}).

In this manual, we mark existing parameters that cannot beused simultaneously (alternative parameters) with the "|"symbol between the two alternatives. The "|" symbol is notprogrammed.

Example: FKT (PA<pa>|PB<pb>).

If a parameter is an axis name which ends with a figure, theparameter name must be separated from the value by a blankor “=”.

Example: FKT (X1 75, Y1=44).

As a matter of principle, the function names and parameters are onlyeffective by sets, i.e. even equal parameters and keywords must berepeatedly programmed in the following block. All parameters must beconstants, i.e. they must not contain any expressions or inline CPL.

Coordinate values must always be specified as absolute values. Theapplicable linear measuring unit (mm/inch) is always the measurementunit that is active after the basic channel position or mm, i.e. the basicprogramming unit. Coordinates with the X axis meaning can be specifiedin the diameter size, if necessary. Angles are always measured indegrees.

Geometry Header Instruction CONT(...), PATT(...)Each geometry definition starts with a header instruction. On selecting thefunction, it is also determined whether it is a contour or a train of drillingpositions.

The header information contains the unique ident of the definition(applicable within the program file) and assigns the definition to a specificdescription coordinate system.

is the unique ident number (>0), and

is the description coordinate system.

The description coordinate system assigned to the definition (called DCS,Description Coordinate System below) essentially defines the axisidentifiers and the interpolation plane to be applicable to the two-dimensional definition.

The DCS has the following characteristics:

• Radius/diameter programming (RAD/DIA);has an effect only on the NC axis with the X functionality.

• Plane (G17, G18, G19, or G20).

• Axis identifiers (e.g. X Y Z).

• Reference radius for cylinder jacket transformation (RI).

The DCS declaration must satisfy the following syntax:

{<Xsc>} {<plane> {({<axis1>}, {<axis2>} {, {<axis3>}})} {RI<ri>}

where

defines whether the axis with the X functionality is programmed in theradius or diameter size, with the possible words being RAD and DIA. If<Xsc> is not programmed, the condition after the basic channel positionor RAD is applicable.

stands for the interpolation plane, with the possible words being G17,G18, G19, and G20. If no plane is specified, the plane activated after thebasic channel position or G17 is applicable.

stands for the name of the axis with the X function.

stands for the name of the axis with the Y function.

stands for the name of the axis with the Z function.

The definition of the plane is linked to the axis identifiers according to theNC syntax for the extended plane conversion (see Rexroth IndraMotionMTX Programming Manual DOK-MTX***-NC**PRO*V02-AW01-EN-P,Section "Extended Plane Conversion").

The feed axis for the particular interpolation plane (applicate) may beomitted. In this case, it will not be addressed by the GNP cycle (e.g.G18(X,,Z)). At the same time, a non-defined feed axis restricts the scopeof usable GNP cycles (e.g. drilling not possible).

If the list of axis names is not programmed, the logic axis names of thesynchronous axes in the basic channel position are applicable. If logicaxis names are not available, the appropriate physical axis names areapplicable.

The DCS corresponding to the basic position in all of its parameters is thedefault DCS. If the default DCS is used, the DCS declaration may becompletely omitted in the header information.

Programming Trains of Contour Elements

Elementary Information on Trains of Contour ElementsAn "NC-compatible" workpiece drawing should contain all coordinatesrequired for programming lines and circles. Since drawings often reflectdesign requirements rather than technical production requirements, thedetermination of coordinates often require extensive mathematicalcalculations. This is essentially facilitated by the function of programmingtrains of contour elements.

A train of contour elements is the definition of a contour of any shape. Ithas a beginning (starting point) and ends with the last contour elementbefore END_CONT. There are no interruptions in-between.

Trains of contour elements are subdivided in open and closed contours.The starting and end points of the latter are identical.

Examples

Function

Syntax

Examples

Function

The definition of a train of contour elements consists of a starting pointand any number of contour elements (lines and arcs) as well astransitional elements. That means that the following elements areavailable for describing a contour:

• Starting point

• Straight line (line)

• Circle (arc)

• Transitional elements between two lines or arcs:

• chamfer,

• rounding,

• undercut, and

• thread undercut.

The given parameters of a contour element are used for calculating thecontour element. If these fail to be conclusive, the previous and thefollowing elements are also included in the calculation. The definition canattain its geometric determination by re-calculating up to two contourelements before the last (transitional elements are not included here). Anexcess determination is impermissible and will cause error messages.

Starting Point SPT(...)The starting point of the train of contour elements is defined in the twomain axes of the DCS.

The SPT instruction follows immediately after CONT; it may be writtenonly once per contour definition.

SPT {<SP>}

where

stands for the starting point coordinates. They define the starting point inthe first axis of the plane (horizontal axis, abscissa) and the second one(vertical axis, ordinate). The axis name must be specified for each axis,followed by the coordinate value. The parameters are separated by acomma.

The starting point of the contour is at X20 and Z0.

SPT (X20, Z0)

Line LIN(...)A contour element is defined as a line.

LIN {({<trs>} {,<EP>} {, AA<aa>} {, R<r>} {MD<md>})}

where

defines the angle of lead via the tangential connection to the precedingelement. TG stands for tangent, TR for the reverse tangent and as defaultcorner transition.

stands for the end point coordinates, which define the end point in the firstaxis of the plane (horizontal axis, abscissa) and/or the second one(vertical axis, ordinate). The axis name must be specified for each axis,followed by the coordinate value. Two coordinate value parameters mustbe separated by a comma.

stands for the lead angle in absolute relation to the positive horizontalaxis.

stands for the length (radius).

stands for the possibility of selection from several solutions (MD1 or MD2;MD1 is the default value).

Clockwise:

CW {({<trs>} {,<EP>} {, <IP>} {, AA<aa>} {, EA<ea>} {, OA<oa>}{, R<r>} {MD<md>})}

Counterclockwise:

where

Elementary Information on Form ElementsForm elements are geometric elements belonging to the group ofcontours. Herein, these contours comply with a form pattern that recurswith many workpieces.

The definition of a form element must always start with "CONT" and endwith "END_CONT".

A contour definition may contain any number of successive formelements. In this case, the contour comprises interruptions. It is alsopossible to combine form elements and manipulations of contours in acontour definition.

Note: In milling cycles, non-coherent contour segments are treatedas separately programmed contours with regard to approach,run-out, infeed, "closedness", etc. In turning cycles,interrupted contours cannot be processed.

Programming Manipulations (Mirroring, Turning, and Moving)

Elementary Information on ManipulationsManipulation instructions serve to define a new contour or point set bymirroring an already programmed geometry or by turning or moving it ntimes. That means that manipulations are transformations.

Several successive manipulation instructions are permitted in one and thesame geometry definition. The resulting geometry is then considered tobe the summation of several starting geometries which have, in turn,originated from transformations.

Note: The DCS of transformed geometries must comply with theDCS of the starting geometries.

Depending on the parameters specified and on the transformationfunction, the resulting contour may consist of several non-coherent singlecontours. The algorithm of the transformations is designed such thatpriority is given to merging resulting contours (starting and/or end pointsare brought together). If necessary, the direction of contour pieces isreversed (mirroring function).

If merging is not possible, the resulting contour comprises interruptions.

Contour manipulations can be combined with the form elements in acontour definition.

Note: In milling cycles, non-coherent contour segments are treatedas separately programmed contours with regard to approach,run-out, infeed, "closedness", etc. In turning cycles,interrupted contours cannot be processed.

Manipulations of point sets may be combined with point set definitions.

Mirroring MRR(...)The starting geometry is mirrored about the straight line defined by apoint/angle. In addition, it can be defined whether or not the targetgeometry should include the source geometry. Herein, the direction ofdefinition is, at the same time, reversed internally for the partial resultmirrored. Mirrored contours can then be machined with the same radiuscorrection direction as the starting contours (milling).

Stock Contour for SimulationThe definition of a stock contour for the simulation of turning operationswith the syntax mentioned below permits to use a predefined contour fordescribing the shape of the stock directly in the simulation and, thus, toeasily describe preformed stock. This type of stock definition forms a linkbetween the GNP and the simulation.

The contour must have been described in a DCS of plane G18 withdiameter programming. The contour must not comprise any self-intersections or loops. It does not have to be closed. A non-closed stockcontour is closed internally by a connection line.

The stock definition should be inserted near the program start.

If the preformed stock is defined in a subprogram, at least one DINinstruction must be contained in the line next to the "//STOCK/...“comment.

2.2 Machining Cycles

Fundamental Information on GNP Cycles

Machining cycles are technological subprograms which can be used toimplement a machining process. The actual machining sequence resultsfrom the parameters of the cycle. There are three groups of GNP cycles:

• turning (including center drilling),

• milling, and

• drilling (driven tools).

A cycle is called up by specifying the appropriate G-code. This code isfollowed by the necessary parameters in parentheses.

Before the cycle can be called up, the machining tool, the appropriatespindle speed or constant cutting speed, the direction of rotation and, ifnecessary, the gear stage must be programmed in the NC program.Where turning cycles and drilling cycles with one feed being effective perspindle revolution are concerned, the feed spindle must be definedbeforehand with MAINSP.

All GNP cycles preselect the appropriate description coordinate systemprior to machining and deselect it again after machining. This isapplicable, without any limits, for setting the radius / diameterprogramming and the interpolation plane. Transformation functions andfree plane definitions can be activated and deactivated optionally in thecycle. This requires that additional block sequences be declared in theDCS ("DCS", p. 1-38).

The DCS assigned to the cycle is the coordinate system which was filedin the header information of the geometry definition to be machined oredited. (Turning) cycles not using any contours or point sets always usethe default DCS.

Before the cycle is started, a safe starting position must be approached,from where it is possible to move the tool to the starting position of themotional sequence without any collisions. At the end of the cycle, the "toolretract" parameter can be used in various versions to move back to thestarting position before the cycle. Where milling cycles are concerned, thereturn motion is limited to the drilling or feed axis (applicate).

At the end of the cycle, the conditions regarding the previouslyprogrammed G-groups and M-groups having been applicable before thecycle has been called are present. In other words, they will be set againinternally at the end of the cycle.

The actual NC control blocks representing the cycle are formed in what iscalled a compiler run and are internally provided as a subprogram.

All parameters are provided with their own parameter address, thusallowing any order of parameters in the NC block. Parameters areseparated by a comma. Decimal places are separated by a "point".Mathematical expressions in the form of arithmetic operations andvariables are not permitted as parameter values.

Functions that have not yet been implemented are “dimmed”.

Note: It is not possible to represent all parameter constellationsincluding their effects which are theoretically conceivable. Forthat reason, only those circumstances with regard toparameters and cycles which are the most frequent in practicewill be described in the sections below.

CAUTION

Since the number of possible combinations ofgeometry and machining variance is very great, theNC programmer has to take the necessary carewhen he checks and incorporates the results.Among others, a recommended tool for this check isthe NC simulation.

Prior to cycle processing, default values are assigned to the parameterswhich are no mandatory parameters of the cycle and which have not beenprogrammed explicitly. Some of these default values can be adjusted via"Options"; others cannot be changed. This is indicated under "StandardSettings" in the parameter description.

DANGER

Copying NC programs from other channels /devices with possibly deviating defaultparameter settings causes the risk of collision!⇒ When transfering NC programs, please check

whether the cycles still comply with the possiblydifferent standard settings.

Before the cycle is executed on the CNC, the tool edge position and thetool edge radius are checked for compliance with the tool edge positionand radius set on creation of the cycle. If they fail to comply, a warning isdisplayed on the CNC. In this case, the start of the cycle must beseparately confirmed by the user. (Tool tests are not carried out yet inthe present version.)

stands for the general oversize which must remain after machining, forfurther machining steps on the contour if necessary. It is applicable to theentire contour, unless an additionally programmed oversize for vertical orplane surfaces becomes effective with individual contour elements (>=0).

stands for plane oversize, i.e. the oversize which must remain aftermachining, for further machining steps on plane surfaces if necessary. Itmust always exceed the general oversize "RSG". It is assumed that thetool angles permit a "relief cut" that is "RSF" in size on the plane surface.

stands for the vertical oversize which must remain after machining, forfurther machining steps on vertical surfaces (cylinders) if necessary. Itmust always exceed the general oversize "RSG".

Note: Additional oversizes for vertical and plane surfaces mustalways exceed the general oversize RSG because, otherwise,the general oversize will be implemented on these vertical andplane surfaces.

The Options dialog can be used to exclude lines (contourelements) up to a specifiable length from being subjected toan axially parallel oversize. These specifications can bedefined separately for vertical and plane lines in ascendingcontours and in undercuts / relief cuts. For example, thissetting can be used to finish undercuts with a simultaneousvertical oversize on the other vertical surfaces.

Simple Grooving G722(...)The simple grooving cycle G722 can be used to machine grooves whichare rectangular in cross-section in various variants.

Sequence:

The tool is approached in X and Z at the start position plus the "AT"approach path for the first machining cut. The tool edge position specifiedby "TEP" defines whether an internal or an external groove is necessary.This is followed by machining cuts (grooving) in the feed mode. After thegroove base has been reached, a waiting time (dwell time/dwellrevolutions) may elapse until the tool retracts to position "AT" for apossible further grooving cut. If necessary, this is followed by furthergrooving cuts for machining the entire width of the groove. If a "CF"chamfer width is specified, the edges are chamfered on the upper side.To achieve this, a 45-degree bevel is turned (without tool edge radiuscorrection) which is followed by a short travel of 0.2 mm along the flank toprevent burrs from developing. However, the short overtravel is notdeeper than the groove base. There is no change of tool cutting edges onchanging to the other chamfer. At the end of the cycle, the tool returns to"RP" or "AT". Where radial grooves are concerned, this machiningsequence can be repeated several times (offset "DZ", repeat factor "NR").Finally, the tool moves back as specified by parameter "TRV".

Turning Cylindrical Threads G760(...)The turning cycle for cylindrical threads G760 implements the entiremotional sequence including auxiliary motions, which is required forproducing threads by means of a thread turning tool.

Sequence:

Whether the thread concerned is an internal or an external thread, isdetected by the cycle by means of the "SX" starting point and "EX" endpoint variables. Then the tool is fed in the rapid traverse mode in X-direction by the first infeed increment "NI" and with the flank angle "EA" inZ-direction being accounted for. Then, synchronously with the speed ofthe main spindle, a longitudinal cut is made with the pitch "P" until the endpoint "EZ" is reached. Thereafter, the tool is retracted in the rapid traversemode in X-direction for 1 mm above the thread and moved back to thestarting point "SZ". The infeed, longitudinal cut, retract and move-backsteps are repeated until the end point "EX" is reached; at the same time,the infeed is reduced to keep the chip cross-section at a constant value.

The reduced infeed is calculated from the first infeed increment "NI",multiplied by the square root of the "ith" cycle. Then the number of glazecuts "GC" is processed.

Positioning to the starting point "SX" in rapid traverse mode completes thecycle.

Then the tool is moved to the starting position.

Drilling With Multi-Chamfer Step Drill G803(...)The drilling with multi-chamfer step drill cycle G803 implements the entiremotional sequence for drilling with step drills and is suitable for drillingoperations requiring two speeds and/or feeds, such as:

• drilling with preceding centering (drilling a point with low feed),

• countersinking with a counterbore.

This requires that the tool be measured at the large diameter. It is alsopossible to use two cutting edge corners: cutting edge A (chamfer A) isrelated to the large diameter; cutting edge B (chamfer B) is related to thetool tip.

Sequence:

In rapid traverse mode, the tool is positioned to the first drilling point in theplane and then, with its tip, from the previously approached position to thesafety distance "SD". If a specific speed has been programmed for step B(SB), or if "DA" and "DB" are specified, then the speed "SB" or a speedthat has been increased by the ratio of DA to DB is activated (aiming at aconstant cutting speed). This speed or the starting speed is used to drill toa depth defined by "LB" (feed FS/FVS or F; if FV is the only feed defined,it is adjusted with the speed ratio). Then the starting speed is used again.Thereafter, the tool drills to "DT" with chamfer A (large diameter) with feed"F"/"FV"; finally, the dwelling time "DT" is processed, and then the tool ismoved with its tip to the return position "RP" or to "SD" in rapid traversemode.

Shop Floor Programming Simulation 3-1


3 Simulation

3.1 Basic Information

General Information on Simulation

The simulation is an effective graphical means for the visual check ofparts programs and focuses on geometric aspects, such as thedimensional accuracy of the workpiece, the possibility of collisions, thecontact conditions of the tool, etc. In other words, the simulation involvesworkpieces.

The simulation presented here is based on the interpretation of the partsprogram outside of the CNC and is independent of the latter's operatingstate to a large extent. The motion instructions are animated, i.e. theworkpiece in its particular machining state, the cutting edge part of theworkpiece and, if necessary, line graphics corresponding to the traversinginstructions are visible on the screen.

The simulation is an optional part of the Rexroth IndraMotion MTX. It isavailable in two versions, corresponding to the main machining method ofthe machine tools under consideration. The simulation is an integral partof the following technology package for shop floor programming (softwareoptions):

• Simulation for turning machines:including driven tools:Technology package "Shop floor Programming Turning", type code:SWS-MTX***-RUN-NNVRS-D0-SFPT

• Simulation for milling machines:Technology package "Shop floor Programming Milling", type code:SWS-MTX***-RUN-NNVRS-D0-SFPM

Requirements and Conditions of UseThe simulation is an optional component which requires a license. It isactivated by the Bosch Rexroth Service.

The simulation can only be used for milling and turning machines. It isbased on 2½D programming and supports the simulation of turningoperations and of drilling and milling operations including driven tools onturning machines. As regards the coordinate transformation, only the endface transformation and the cylinder jacket transformation (involute type)for turning machines are provided

The simulation for milling machines can only be used for rotary axes Aand B. These rotary axes rotate the workpiece (circular table, dividingunit).

The simulation is based on a partial simulation of the CNC. This results inrestrictions with regard to accuracy of details of the graphics and,occasionally, with regard to the syntax or special program runs.

The NC program is syntactically edited by the interpreter of the simulatorand converted into motions. Almost all instructions which are usually usedin workpiece programs are implemented in the interpreter of thesimulator. The restrictions of the NC program will be treated in more detailin a further section.

3-2 Simulation Shop Floor Programming


The first startup of the simulation on a real control requires someoperations that must be carried out once ("Simulation Startup", p. 3-21).

Simulation Input DataThe NC program the user has selected for simulation (main program) aswell as the subprograms called represent the only input data for thesimulator.

Further NC data, such as zero offset lists, D-corrections, etc. are notconsidered in the graphics. This results in restrictions with regard to thequality of the simulation (e.g. consideration of zero shifts).

On the other hand, however, this approach allows the programmer to testhis NC program practically in any stage of the programming processwithout having to prepare all of the NC data beforehand, such as tool andzero offset lists.

Note: During simulation, NC data must be available on which it canbe referred in NC program (e.g. via ZOTSEL instruction). Ifthis data can not be accessed, a corresponding error status isreached. Anyhow, the contents of this NC data do not have aninfluence on the simulation result.

The programmer can insert additional information for simulation in thecontrol program. Such information will improve the graphical quality of thesimulation. However, this is not mandatory.

Such additional information can, for instance, be used to describe

• the stock and

• the tool shapes.

To achieve this, a special syntax is used in NC comments (to be startedwith "//" ("Additional Information in the Parts Program for Simulation", p. 3-4).

Syntactic and Other Restrictions

There are a number of instructions that have not been implemented orare not permitted. The list below (which is not complete) contains themost important DIN instructions that are typically used in parts programsfor the target applications of turning, drilling and milling with 2½Dprogramming at the most:

• Moving, rotating, mirroring and scaling with SHT(), TRS(), ROT(),MIR(), SCL() and PLS() (in preparation)

• Setting of the program position with G92 (in preparation)

• Tangential circle entry G5

• Chamfers and roundings with CHL, CHS, RND, RNE

• Conversion of length measurement unit G70/G71 (in preparation)

• All commands evaluating information saved in NC data: D-command,G53..G59.5, placements, etc.

• Programming of polar coordinates

• Coordinate transformation except end face transformation and cylinderjacket transformation (involute, depending on the particular version)

Note: Non-implemented instructions usually result in incorrectgraphics.

Additional information in theparts program

Syntactic or geometricrestrictions



The simulation converts only those synchronous axes into graphicalrepresentation the names of which are X, Y or Z, maybe extended by anumeral. The graphic axis orientation is fixedly associated with the nameof the axis.

Rotary axes considered are those with the names A, B and C, maybe alsoextended by a numeral. A rotates about the X-axis; B rotates about Y-axis, etc.

Note: Names reflecting the spatial orientation of the NC axes shouldbe used for their graphical representation. If necessary, theappropriate physical or optional axis names can be used.

Where turning machines are concerned, orientation of the main spindlecan be achieved in the same manner as positioning of the C-axis. Thepertinent M-command must be declared with Mx19 (x = 0...9) in theconfiguration parameters.

For the simulation, an NC program must satisfy the following and othercriteria:

• Start requirements specified from without the NC program are notpermitted. In other words, permanent variables may only be used inexpressions and conditions if they have been initialized beforehand inthe NC program.

• The NC program must not comprise any endless loops.

If a parts program is not suitable for simulation for syntactic or otherreasons, then there are two possible solutions:

• Copy the NC program and simplify or remove the instructionsconcerned.

• Suppress/insert NC blocks for simulation by NC instructions with aspecial syntax.

Note: NC programs which are not parts programs, i.e. do not containany motion instructions, cannot be simulated.

3.2 Additional Information in the Parts Program forSimulation

Stock Description

General Information

Using the stock description, the simulation can create a three-dimensionalmodel of the workpiece and simulate the cutting process as a removal ofvolume. The stock description is used for image dimensioning. Theparticular processing state is used for collision monitoring. The 3D modelis also necessary for calculation of sectional views (full section, halfsection, any other sectional views).

Preferably, the stock description should be inserted before the motioninstructions after the main program has been started.

Note: Stock descriptions in a subprogram do not have any effect ifthey are placed in a block without any DIN instructions. In thiscase, at least one DIN instruction must be added.

e.g. G90 //STOCK/...

If a parts program contains more stock descriptions than one, usually onlythe first stock definition is applicable.

Particularly in the simulation for milling machines, a separate stock can bedefined for every rotary axis position (usually the position of the A-axisand/or B-axis). The particular stock, including its machining state, isredisplayed whenever it returns to this position. Workpiece sides withoutcorresponding stock definition can only be simulated in tool path mode.

Where turning machines are concerned, the stock can be repeatedlydefined for reclamping (in preparation).

Without a stock description, it is not possible to simulate the cuttingprocess, but only the traversing motions. In this case, image dimensioningis based on the space enclosed by the feed motions.

Preformed Stock (Turning the Stock Contour)

Usually, it is reasonable to define a preformed stock in case of cast,forged or pre-turned workpieces. This definition can only be used for the"turning machine" simulation type.

The stock contour is defined with motion blocks by means of the knownDIN syntax of the Rexroth IndraMotion MTX for G1, G2 and G3. Eachcontour corner point is described with its own block. It is started with twoslashes (comment). It must be ensured that the contour is closed. If thisrequirement is not met, the last point of the contour is internally connectedto the starting point by a straight line.

Tool Description

General Information

The tool description only describes the cutting edge part. In combinationwith the motion, the shape of the cutting edge part defines the volumeremoved and, thus, the form of the workpiece. The description of thecutting edge, thus, forms a further requirement for workpiece modeling,but also for the collision aspect which is, however, only limited to thecutting edge part described (collision of the tool cutting edge with theworkpiece in rapid traverse blocks). The specification of the cutting edgeradius or of the tool diameter is additionally included in the tool radiuscorrection as equidistant path.

Note: Manual insertion of tool descriptions is an optional function.But there is also an automatic function associated withprogramming of GNP cycles and supplementing missing tooldescriptions during the simulation preparation phase.

The tool information should be added immediately after the tool change inthe NC program. If the tool form (double tool) is also changed when thecutting edge is changed (G47 ED <cutting edge no.>) or if sides arechanged when grooving tools with more than two cutting edges ED areused, the tool description must be repeated at the appropriate place.

Note: Tool descriptions in a subprogram do not have any effect ifthey are placed in a block without any DIN instructions. In thiscase, at least one DIN instruction must be added. It is notsufficient to jump to the tool change subprogram.

Double-Edged Turning Tools (Grooving Tool)

The grooving tool description form must be used for all double-edgedturning tools.

These may include:

• Grooving tools

• Double-edged circular cutting tools

• Parting-off tools

• Double-edged contour cutting tools

The tool description is related to one of the two possible cutting edges. Itis marked with "R1" and "+" (center point of cutting edge radius) in thepictures below. The first cutting edge of the tool description is active afterthe tool description. The relation to an ED command is only established inthe first following motion block. The opposite cutting edge becomesoperative only after the cutting edge conversion (new ED command that isdifferent from the last one), with the assignment to one cutting edge ED

If more than two cutting edges ED are used between two tool changes,the tool description must be repeated with the third ED command, unlessthe third and any further yet unused cutting edge ED are to refer to thefirst cutting edge of the description rule. After the repeated tooldescription, the rules for cutting edge assignment are applicable again.These facts are illustrated in more detail by means of the followingexamples.

Note: If more than two cutting edges ED are used under a single tooldescription, then the first cutting edge of the description rulewill always be the one addressed with the third and any furthernew ED words.

Note: The tool description must also be repeated if a following newsecond ED word should address the already active cuttingedge.

The tool definition is always analogous for all installation positions. Toachieve this, the dimension sketch must be turned to the desiredinstallation position in the description plane.

If the respectively other cutting edge of the description rule must bedeclared in relation to the first description rule, the width W must bespecified with a negative sign. In this case, the tool edge position code ofthe new first cutting edge must be specified by ITP. The positions of thetool edge radiuses and relief angles remain the same. In other words, R2is still used to program the radius of the right cutting edge, as shown inthe diagram.

Programming with more than two cutting edges ED is illustrated by meansof the example below.

Task: A radial grooving tool (external) is to turn the left flank of a groove 1with ED2 and then the right flank with ED3. As a result of this order, thegrooving width W is to be specified with a positive sign.

Then a further groove is to be turned with the command ED4 which, inturn, is to address the right corner. Since the third (and any further) EDcommand is assigned to the first corner of the description rule in thesimulation, a new tool description becomes necessary; this time,however, the cutting edge width must be specified with a negative sign.

Finally, the same right corner is to be used to machine a third groove. Toensure that certain tolerances are kept, now the cutting edge ED1 is to beused. Since the second ED command ED1 is assigned to the opposite leftcutting edge, a new tool description is again necessary.

Manipulation of the Program Run for Simulation

Some of the parts programs may contain instructions which cannot beprocessed by the simulation. If necessary, it may also be desired ornecessary that the program be simplified.

In other cases, it may be necessary to create defined program startconditions for the simulation, e.g. starting positions for NC axes.

In all of these cases, the instructions mentioned below can be used tomanipulate the program run in the simulation. It is possible to exclude oneor more DIN / CPL blocks from the simulation or to execute a DIN / CPLblock in addition to the simulation.

Deactivation of the simulation:

//SIMULATION/OFF

Activation of the simulation:

//SIMULATION/ON

Block to be executed in the simulation only:

3.3 Preparing the Simulation

Simulation Startup

Simulation with a Real NCOperation of the simulation with a real NC is the normal case. Theapplication case is characterized by the presence of a real NC control withits file system and its current configuration parameter (MACODA) on theone hand and, on the other hand, by the necessity that the emulation(hostlib, virtual NC) must also be used in parallel while the NC program isprepared for the simulation. Here, it must be ensured that

• access to the NC program and to the subprograms it uses is ensuredfor emulation;

• the emulation is operated with the same configuration as the real NC;and

• the emulation uses the same NC data (or other NC data if it is notrelevant for the simulation result).

Intended use

Syntax

Example

Conditions of use



Setting up a common mount directory

To ensure that both the emulation and the real control have commonaccess to the same NC program, the emulation also has to mount amount directory of the real NC in the same manner (identical mountpoint).

During installation of the IndraWorks user interface, such a mountdirectory has already been set up under "C:\mnt". The steps describedbelow should only be carried out if this mount directory fails to meetrequirements or if there are further requirements.

Using an editor, open the "export.us" file in the Indraworks\MTX\Bin folderand update the Windows path name of your mount directory or add anew line (more mount directories than one). The path name must befollowed by "localhost", separated by a blank character.

If it does not exist, a file with this name must be created.

Example:

C:\MyMount localhost

Only directories with "localhost" in their name can be used for thesimulation.

After having saved "export.us", please ensure that the Bosch Rexroth

NFS server is activated (symbol in the task bar). If this is not thecase, this server must be activated via the Control Panel.

Now right-click on the symbol and select "Reload Export.us". Thiscompletes the operating step of "adding/changing mount directories". Thedirectory concerned is now installed as mount directory of the real NC.

When an NC program is simulated for the first time based on the newmount directory, the directory concerned is automatically mounted for theemulation. This delays the preparation process and displays anappropriate message in the status bar.

The simulation also requires that the same subprograms can also beused by the emulation. To achieve this, copy all subprograms to a folderof the commonly used mount directory.

Adjust the MACODA parameter 3080 00001 "Search path forsubprograms" according to the new memory location of yoursubprograms. The parameter can be reached in IndraWorks Configuratorvia path NCO -> FileOrg -> SubProgPath.

Adjustment of configuration parameter (MACODA adjustment) )

New (changed) configuration parameters are applied automatically by theemulation on preparation of the simulation. This does not require anyadditional operator steps.

Ensuring compliance of the configuration delays the preparation processand is displayed in the status bar.

Compliance of NC data

NC data and subroutines residing in the root directory or in the /usrfepdirectory or in the subroutine of /usrfep cannot be provided by commonemulation mounting, but only by being copied to the file system of theemulation.

Activation of same data (e.g. anwperm.dat, wmhperm.dat machdef.dat)requires the restart of the emulation. This leads to further delays duringadjustment procedure if modifications are in this data ("MTXCompiler.INI",p. 3-52).

Adding/changing mountdirectories

Mounting by the compiler

Search path for subprograms



Note: For purposes of efficiency, NC data should preferably besaved to a common mount directory. In this case, datacalibration is not necessary.

Simulation with an EmulationUsing the running emulation

If the user interface of the IndraMotion MTX is operated with an emulation(case of application in the work preparation or development phase), thealready running emulation is used for preparing the simulation (defaultcase). The simulation will have an effect on the operating mode, the NCprogram selected and the process indicators.

Startup of the simulation does not require any additional steps.

The NC programs, subprograms and NC data may reside in anydirectories. There are no restrictions. Ensuring compliance of theconfiguration parameters is not necessary.

Using the second emulation in the background

If the user interface of the IndraMotion MTX is operated with an emulation(case of application in the work preparation or development phase), it isalso possible to start a second emulation in the background for preparingthe simulation. The simulation will then not have any effect on theoperating mode, the NC program selected and the process indicators ofthe already running emulation.

If not yet available, the MTXCompiler.ini file must be created inIndraWorks\user\config by copying the file of the same name fromIndraWorks\config. Using an editor, the "UseRunningEmu" entry must beset to "0".

The subprograms and NC data which are not subjected to any changes(e.g. by editing) can reside in any directories. Any other data and the NCprogram itself must be filed to a mount directory. NC data andsubprograms which are not saved to this mount directory are currentlyprovided to the simulation only after the file system has been saved. Toachieve this, exit the user interface and exit the DOS box of the Sco.exefile by entering "14".

Preparatory StepsTo prepare an NC program for the simulation, a number of steps must becarried out once before the graphic is displayed. These steps provide allinput data to the simulator in the form expected. The NC program isprocessed by a compiler. This requires the following steps:

• Resolve GNP cycles and stock descriptions

• Exclude or insert NC blocks for the simulation.

• Resolve CPL and subprogram jumps by using the emulation (Hostlib).

• Insert missing tool descriptions.

• The simulator interprets and processes images.

Resolving GNP Cycles and Stock DescriptionsIn this step, compilation is achieved with the GNP compiler stage. Using"//STOCK/ID<id>", create a subprogram file for each GNP cycle of themain program and the stock description. Please note that a temporarymain program is created for the simulation. This temporary main programis deleted at the end of the simulation and ensures that there are nocorrelations between the simulation and the processing of preselected oractive NC programs.

Excluding or Inserting NC Blocks for the SimulationThis step converts all NC blocks of the main program, which are presentbetween the "//SIMULATION/OFF" and "//SIMULATION/ON" NCinstructions, into comment lines. Comments with"//SIMULATION/<instructions>" will become genuine DIN and/or CPLblocks.

Resolving CPL and Subprogram Jumps by the Emulation (Hostlib)The following step is intended to resolve the CPL contents in the program,such as subprogram jumps and program control structures.

After it has been created, the temporary main program is preselected andstarted by the emulation (automatic block search mode).

The progress of the program is displayed in the status bar. If occurring,runtime errors and warnings are displayed after completion of thepreparatory steps.

Inserting Tool DescriptionsTool descriptions should be added immediately after the tool has beenchanged, i.e. before the first subsequent motion block. Unless he hasalready done this manually, the programmer is supported when usingGNP cycles. This requires that one or more tool changes have beendescribed in the parts program.

The tool change is detected by means of the instruction declared as toolchange instruction in the MTXCompiler.INI file in the[SIMCOMPILER.DLL] section under the parameter "ToolChange"("MTXCompiler.INI", p. 3-52).

Only DIN instructions which are reliably and exclusively run on each toolchange (when, e.g., the modal M-function "M6" is called or in the toolchange subprogram itself) may be used as possible entries. Names ofsubprograms are not suitable. If you fail to find a DIN instruction uniquelyused in connection with the tool change, then please use a different oneand supplement it with a unique comment in round brackets (e.g. "WAIT(###Special label for tool change###)").

Prerequisites:

Tool change text feature



If there is no tool description between two successive tool changes orbetween a tool change and the program end, then the simulationpreparation function itself attempts to insert tool descriptions immediatelyafter the tool change. In this process, the tool type and dimensions arederived from the GNP cycle parameters.

Note: The automated insertion of tool description is only intended tosupport the NC programmer and is not limited to the mainprogram. If necessary (wrong tool type or inappropriatedimensions), the manual specification must be used for thetool description.

If GNP cycles (Graphical NC Programming) are called up, the informationon the particular tool that is provided by the cycle parameters is convertedin a tool description and is inserted immediately after the tool change. Anydescription parameters that are not contained in the cycle aresupplemented by reasonable assumptions.

Tool descriptions that are specified manually after the tool changesuppress the automatic insertion of the description for this tool.

Note: The generation of tool descriptions from GNP cycleparameters can also be used if "Apply DIN Code" has beenselected from the GNP cycle dialog. This can be done only ifthe comment "//_TOOL/…" is not deleted or changedsubsequently.

Interpretation and Image Processing by the SimulatorIn the last step, the NC program is interpreted by the simulator. Themotion instructions including offset calculation are processed to form asequence which, e.g., also allows backward and stepwise simulation.

Preparation is completed by creating a 3D model and calculating theimage dimensions (scale for a full-screen workpiece).

3.4 Performance and Structure of the Simulation

Calling the Simulation

As a rule, the simulation is related with the channel activated on theinterface. If the main program contains a channel ID in the first line, thenthe channel filed there is considered to be the target channel for thesimulation (see Rexroth IndraMotion MTX Programming Manual DOK-MTX***-NC**PRO*V02-AW01-EN-P, Section "Channel ID").

If the program does not contain any channel ID, the desired channel mustbe activated on the user interface if necessary (channel selection).

The simulation can only be started from the list view in the "Program"operating area. To achieve this, select the parts program to be simulated(cursor keys or mouse). Please note that the NC program must have the".npg" extension for NC programs.

Once an NC program has been selected, then an additional F-key <F8>"NC Program Functions" becomes visible. After <F8> has been clicked,the screen switches to a second F-key level providing the key <F2>"Simulation".

Simulation Performance

Overview of Performance and Method of OperationEssentially, the simulation provides the performance features describedbelow. These performance features as well as the particular andassociated features described here will be refered to in the followingchapters.

Up to 4 different simulation views are possible at the same time. Thereare 6 orthogonal views and one 3D view.

The simulation can be run in the sequential mode, that is a method ofoperation comparable to the automatic mode of the CNC, and in the stepmode.

The step mode cannot be directly compared with the CNC mode"automatic single block". The simulation only allows a stepwise approachwhere a step is always a motion block.

The step mode can be used in forward and backward directions.

In the step mode, a box showing the from and to coordinates per block isdisplayed.

SIM_StepBox_gr.bmp

Fig. 3-17: Simulation in step mode with displayed coordinate box (turningmachine)

View

Sequential mode and step mode

The solid mode permits three-dimensional modeling of the workpiece.This mode provides collision monitoring and the representation ofsectional views. This mode requires the presence of a stock description.

The tool path mode does not provide 3D modeling. The screen onlyshows the programmed path as a polyline. This mode is the only oneprovided if there is no stock description.

These two modes can only be toggled via the Options dialog ("SimulationOptions", p. 3-41).

The cutting edge and the tool are monitored for possible collisions whilerapid traverse motions are made. If a collision is detected, the simulationis stopped and a box showing the from and to coordinates and anappropriate message will appear. Any portions of the workpiece surfacethat are involved in the collision are shown in a separate color.

The collision monitoring function is only provided in the solid mode andcan be deactivated if necessary ("Simulation Options", p. 3-41)

The velocity behavior does not correspond to the real velocity behavior atthe CNC.

In the tool path mode, every motion block is subdivided in several partialsteps. The animation rate can be regulated with the numeric keys 1 (slow)to 9 (fast).

The solid mode does not provide the possibility of regulating the velocity.Every motion block is represented in one line.

The image detail of every view can be changed by means of the zoomfunction.

The move function is the second possibility of changing the visible imagedetail.

The image detail can be easily moved by pressing the <ALT>+<cursor>keys at any time.

In addition, the workpiece can be rotated about almost any angle in a 3Dview.

The graphic can also be rotated by pressing the <CTRL>+<cursor> keys.

During simulation, any other views can be defined, for instance, in orderto permit approved evaluation of the geometry of inside forms:

• Lengthwise cuts (axially parallel sectional views)

• Radial cuts ("pie sections"; turning machine only)

• Vertical cuts (Z-parallel cutting plane, defined by two X-Y coordinates;milling machine only)

This cuts effect in all graphic windows at the same time and are retainedup to closing the simulation ("Determine Cut", p. 3-38).

The rotation simulation provides the following further sectional viewswhich can be selected separately for each graphic window and which willbe maintained permanently:

• Half section and

• Full section.

The simulation covers a great variety of configurations/types of turningmachines. These include driven tools as well as multi-spindle turningmachines (spindle and counter-spindle).The orientation of the views can be adjusted to the machine type. Thepresent release takes horizontal and vertical machines (suspendedspindle) "behind the turning center" into consideration.

Fig. 3-19: Simulation screen structure

The graphic windows are the graphical output areas for simulation, i.e. theviews. Up to four different views can be represented at the same time.The window with the focus is identified by blue borders.

The NC program window displays the NC program and the subprogramscalled by the NC program. During the simulation, the cursor is alwayspositioned on the current NC block. The NC program window can also beused for interactions (e.g. searching).

The status bar provides information on current conditions, such ascoordinates, feed and spindle value. The coordinates are superimposedby the cursor position.

ZoomZooming is the function for magnifying or reducing the image. Zoominghas different effects in the solid and the tool path modes.

In the solid mode, zooming is based on the magnification of the modelthat is cut off at the zoom limits. This becomes clear when the model ismoved subsequently.

Zooming results in a complicated recalculation of the solid model andrequires calculating time.

The tool path mode provides quick zooming of the views.

The graphic windows provide three different functions which are executedwith the mouse and change the graphics. Each of these functions isrepresented by its own cursor type. The zoom function is the defaultfunction and is activated whenever a cross-hair is visible.

Zooming with the mouse is the first option of magnifying an image detail.Move the cursor to the first corner point of the desired image detail(rectangle) and, while holding the left mouse button, drag it to the secondcorner point. Release the mouse button. The new image will becalculated.

Zooming with keys has the same function as zooming with the mouse andcan be used if a mouse is not available. This function is described in thesection on the graphic windows F-key bar.

Zoom +/- efficiently magnifies or reduces the image in relation to thecenter of the image. These F-key functions are recommended forzooming if a mouse is not available.

MoveThe moving function allows to change the visible image detail withoutchanging the scale.

Moving is a further function of the mouse pointer which is indicated by itsown "Move" cursor type, i.e. a cross with arrows.

The "Move" cursor type is visible whenever <F2> "Move" has beenselected. Move the mouse pointer to move the detail in the samedirection. Press <ESC> or click <F9> to reset the cursor type to the cross-hair cursor.

Moving with function keys is also possible by clicking <F2> "Move". Theopening F-key level "Move with keys" provides a separate key for everydirection.

Moving with shortcuts allows to move the image detail irrespective of thecurrent cursor type. To achieve this, use the cursor keys in combinationwith the <ALT> key.

TurnThe turning function allows to rotate a 3D view to any position. Toaccelerate the graphical representation, the tool path mode is temporarilyactivated. After starting of the animation or pressing of the ESC key, thesolid model will again become visible.

Turning is the third function of the mouse pointer in the graphic windowswhich is indicated by its own "Turn" cursor type. This type is identifiedby a cross with arrows on a spherical surface.

The "Turn" cursor type is visible whenever <F3> "Turn" has beenselected. Move the mouse pointer to turn the workpiece. Press <ESC> orclick <F9> to reset the cursor type to the cross-hair cursor.

Turning with function keys is also possible by clicking <F2> "Turn". Theopening F-key level "Turn with keys" provides a separate key for everydirection.

Turning with shortcuts allows to move the graphics irrespective of thecurrent cursor type. To achieve this, use the cursor keys in combinationwith the <CTRL> key.

Determine Cut

General Information on Sectional ViewsThe freely definable cuts treated here are not the same as those of the"Sectional view" setting of the popup menu. Whereas, in the popup menu,the half and full sections can be specified window by window and thissettings are retained also after exiting the simulation, the freely definablecuts are intended to be in all graphic windows at the same time and onlyup to exiting the simulation. The freely definable cuts overlap with the"Sectional view" settings of the popup menu.

Note: The display of sectional views is only available in the solidmode.

Cut radialA radial cut removes an angular segment of the workpiece (specified bythe angle about the vertical axis).

Circular Table PositionThe "Circular Table Position" dialog permits the simulation to be run for aspecific position of the rotary axe only (turning the workpiece, A and/or Baxis positions) or completely across all positions. The dialog guide ismainly designed for a B-axis or an A-axis (circular table), but also allowsany combination of A and B positions.

Note: The "Circular Table Position" function is only available for thesimulation of milling machines.

SIM_SelectRAPosBox_gr.bmp

Fig. 3-34: "Circular Table Position" dialog

The four upper buttons can be used to select the 0-degree, 90-degree,180-degree and 270-degree sides (either A or B position). The sidesinclude the appropriate multiples of 360 degrees.

Only those buttons are provided for which a rotary axis position A or Boccurs in the NC program.

If positions different from multiples of 90 degrees or any combinations ofA and B angles occur in the NC program, then the position desired can beselected from a list. This is achieved by clicking the button to the lowerleft.

The button to the lower right allows to simulate the program in its entirety.Here, it must be noted that a separate graphic is displayed for eachposition of the rotary axis, i.e. the correlation among several sides cannotbe tracked visually.

Simulation Error Messages

Errors and WarningsSimulation error messages may have two causes:

• Preparation:These messages are generated by the compiler and mainly containerrors related with the GNP and runtime errors.

• Simulation start:The simulation error messages are always displayed on start of thesimulation and after completion of the preparation by the compiler.They are detected on syntactic and geometric preparation by thesimulator.

After an error has been detected, the NC program must be correctedand/or the error cause be eliminated.

Warnings only occur during the animation. The most important warning isthe collision warning.

Could not calculate the equidistant arcThe tool edge radius of an internal arc travelled with tool edge radiuscorrection is greater than the circle radius. Correct the preceding tooldescription ("Tool Description", p. 3-9).

Instruction in simulation not realizedA DIN instruction that is not implemented in the simulator occurs in theNC program. If possible, simplify the NC program ("Manipulation of theProgram Run for Simulation", p. 3-21).

Internal errorAn exception caused premature termination. This error cannot beeliminated. If necessary, the user interface must be exited and restarted.

File Meaning and Origin

The file described below contains all options of the simulation. The userinterface automatically creates this file when the simulation is started andfills it with a number of presettings. Since a few assumptions are madewhen the file is created, it must be manually revised or edited with theOptions dialog of the simulation, if so required in case of certain machineconfigurations.

The file resides in the <Installationsverzeichnis>\IndraWorks\user\configpath; file name: MTXSimConfig_xxx_yyy.INI (with xxx being the devicename (presently always "000") and yyy being the channel number).
