user-friendly shop floor programmingManual Guide i, the user-friendly software for shop floor programming, makes it easier for you to operate the machine. The innovative programming enables development from a drawing to a production part in a very short time. Thanks to Manual Guide i, FanuC CnCs can be programmed, very easily and quickly, for turning, milling and compound machining. Self-explanatory menus and graphic simulations guide the user through the programming, producing highly efficient results even for complex machining processes.

The FanuC Manual Guide i software is based on the iSO code format and has an ergonomic CnC user interface for programming cycles. it uses a Graphical user interface with user-friendly icons which allow you to interactively create part programs in just a few steps. all of the relevant information is displayed on one CnC screen. Having to constantly change between screens is thus avoided as is the risk of getting lost in the numerous pop-up screens.

This training book will give you an overview of Manual Guide i software for the programming of lathe applications, including three practical programming examples. it was developed by specialists and will facilitate your introduction to Manual Guide i software. You will be ready to program even complicated parts with Manual Guide i once you have worked your way through the three examples.

We wish you lots of fun and success when programming. We would be delighted to hear from you if you have any suggestions relating to this training document.

1. introduction

MeM (execute or graphically simulate a program)

JOG (manual operation).

4.1 edIT operating mode

The ediT operating mode has clear and self-explanatory menus. The user can select from among the fol-lowing: create, change, copy, delete a new program as well as input or display the program on an exter-nal data carrier.

using the soft keys, you can select all other menus from the main menu.

Self-explanatory, easy-to-use data input menu for the turning cycle:

4.1.1 Creating a new program

To create a new program, press the soft key “new Program”

Then enter a program number between 1 and 9999, e.g.: 100 and press the soft key “CReaTe”. The program no. 100 is opened.

if a program number has already been allocated, it is indicated by a corresponding message.

The new program is entered as follows: STaRT CYCle eNd

each cycle consists of the following two parts: Cutting conditions Geometric data (workpiece contour)

10

4.1 ediT operating mode

11

Program start: STaRT

a personal template can be predefined for the program start and be simply called up by pressing the soft key “STaRT“ in the Selection menu.

The required data for workpiece machin-ing is entered step by step. The diagram of the program start with the description of the blank part for graphical simulation as well as tool function or replacement are repeated with minor modifications.

The controller allows you to store recurring program parts as a template in the start menu and to easily call them up as required. Typical application examples are: program start, tool function or tool replacement and program end.

The blank part definition has its own selection and input menu.

Machining: CYCle

There are a wide variety of machining cycles available for lathe machining. To select the required cycle press the soft key CYCle.

Selection is uncomplicated as can be seen in the illustration below. in this example the exterior of a cylindrical blank part is being machined. The corresponding menu is selected via the cursor and confirmed by pressing the soft key “SeleCT”. The cutting conditions menu then appears on the screen.

Cutting conditions

The cutting conditions are entered into the following screen mask:

after the cutting conditions have been entered, the contour description screen mask automatically appears.

example of workpiece

The workpiece contour to be machined is geometrically described as per the drawing.normally this figure can only be programmed by an experienced programmer. This problem can be easily solved with the Manual Guide i.

Workpiece contour for the cycle

The workpiece contour is described with the help of the following soft keys:

in the illustration below you can see the entries for radius 40 of the previous example.

Only the positions seen in the drawing for the centre point and the radius are entered. The finish points are unknown.

The adjacent graphics automatically appear, once the entry is complete. You can track the previously entered contour elements at the top of the screen.

unknown transitions are automatically calcu-lated by the CnC.

7.

Contur end X20 Z0

The above workpiece contour is described with a few simple entries!

The workpiece contour also has the option of being stored as a separate subprogram so that the figure can be used for multiple operations, e.g. roughing and finishing. This considerably reduces programming.

4.1.2 Program list

all the programs in the program list are displayed when the soft key “0 lIST” is pressed.

The following information is displayed: program number, comment, date of creation or alteration, time, size of the program and cycle time.

Program list options:

NeW new program M-CaRd Memory card COPY Copy program all del delete all deleTe delete program SRTORd Sort programs edCOM edit comment OPeN Open program SeaRCH Search program

Program input and display

The CnC controller conveniently allows you, by means of a standard memory card, to rapidly read in/out programs and all other data such as tool offset, as well as machine and controller data. The reading in/out of data is fully controlled by the menu using the soft keys.

The content of the memory card can also be displayed on the CnC controller screen. This guarantees an unrestricted, uncomplicated and above all a quick data exchange.

4.1.3 Changing the program

Press the soft key “OPeN” to display and subsequently make changes to the program.

By pressing the soft key “alTeR”‚ cycles are reconverted into the original input menu.

in the following example, the cycle G1120: TURNING (OUTER ROUGH) is selected. The precise meaning of the respective function is displayed in the marked field.

The changes are made in the input menu and are accepted by pressing the soft key “alTeR”.

4.2 MeM operating mode

Programs can be graphically simulated, executed and converted to din/iSO in this operating mode.

4.2.1 Graphically simulating the program

a program is graphically simulated in this operating mode. There are two different types of display:

a) Solid body graphical animation b) Tool path-line graphics

The machining is realistically displayed in solid body animation. You see the material removal by the corresponding machining tool. The movement of the tool tip is displayed as a line in the tool path-line graphics.

Zoom Function

By selecting the area using soft keys, detailed magnifications can be easily achieved.

it is as easy to operate as a dVd player.

4.2 MeM operating mode

18

4.2.2 Converting the program into ISO format

a “Manual Guide i” program can be fully converted to a standard iSO program. Such a program is hence not dependent on the make of the CnC controller. as a result you have the option of universally using the “Manual Guide i” program in the entire production area.

4.2.3 Executing the program

a program created using the “Manual Guide i” can be executed directly in the original format. You do not have to convert the program to execute it.

4.3 JOG operating mode

The machine can be manually operated in this operating mode. using the JOG keys or a hand wheel, the feed of the axes being processed can be either manually selected or at rapid. amongst other things, the workpiece zero point and offset are determined if the machine does not have an automatic measuring device or has no external tool pre-setting.

4.3 JOG operating mode

19

The workpiece rotates in a standard lathe. it is clamped in a chuck or a collet chuck. The machining tools are secured in the tool holder (indexer/turret) and are moved in two axes, in the Z direction (longitudinal motion, parallel to the headstock spindle axis) and in the X direction (transverse motion).

5.1 lathe co-ordinate system

There are also lathes with more than two axes. The work spindle can be designed as the “C” axis. it can then be positioned at any angle or its feed can be controlled so that it is possible to drill and mill with rotating tools at the face or lateral surface.

if the tool holder (indexer/turret) can also be adjusted heightwise it is the “Y” axis. There are also machines with a counter spindle, where the workpieces can be automatically machined from two sides.

The different machining levels are differentiated by G codes:

G18 = Movement in the axes XZG17 = drilling and milling on the face at the end face XYG19 = drilling and milling at the lateral surface YZ

5. General information

20

5.2 Zero point selection

each moving axis of a CnC machine has a measuring system. Once the machine has been switched on, these measuring systems must be synchronised with the CnC controller. There are reference points for this purpose in the measuring systems, which are found at the positive end of the axis’s traverse path and are usually started manually. There are also machines with absolute measuring systems whereby the reference points are superfluous.

Symbol for the reference point

The workpiece zero point can be freely selected from the entire positioning range. The user logically sets the zero point to be programmed at the place it is easiest to program. This is nearly always in the Z axis (the front of the workpiece diagram) in the case of a lathe, and is the centre of the work piece in the X axis. The X axis dimensions are programmed in diameter.

Symbol for the workpiece zero point

5.2 Zero point selection

21

Minimal knowledge of iSO programming is required for program inputting with “Manual Guide i”. Machining cycles are called up via 4-digit G functions. The G-code itself is irrelevant to the user as the data is entered by graphic input displays. There are very few G-functions which the user must know in order to be able to work with “Manual Guide i”. These are explained below.

G0 = Rapid Traverse

With the command “G0”, one or several machine axes can simul-taneously be moved. The axes in question move at high speed from the start to the target point without interpolating,

e.g.: G0 X100 Z2.

G1 = Feed

With the command “G1” one or several machine axes can simultaneously be moved at a programmed feed rate. in this case, the axes in question move along a straight interpolating line from the start to the target point.

For lathes the feed is normally programmed in mm/revs,

e.g.: G1 X100 Z-50 F0.3 (F = feed rate).

G90 = absolute programming

in the case of absolute programming, all of the programmed positions refer to the selected workpiece zero point.

Example G90 G0 Z-50 Z-70 Z-110 Z-140 Z-170 Z-200

6. iSO programming

22

G91 = Incremental programming

in the case of incremental programming, each dimension refers to the previous position.

Example: G91 G0 Z-50 Z-20 Z-40 Z-30 Z-30 Z-30

The functions G90/G91 and G0/G1 are “self-maintaining (modal)”, which means that they remain active until they are overwritten by the corresponding “counter function”.

G96 = Constant cutting speed

This function serves to keep the cutting speed, for each workpi-ece diameter, constant at the tool tip.Through the G96 function, the CnC controller automatically calculates the corresponding speed for each diameter position (X axis). The work spindle speed is constantly altered in the case of facing, taper turning or radius turning.The cutting speed is programmed in m/min as address “S”. as the diameter increases the speed decreases; for smaller diame-ters the speed can increase up to the maximum possible speed. To avoid damage due to centrifugal forces, the speed can be limi-ted to the respective program through the corresponding com-mand (see G92 speed limitation).

Example: G96 S250 s [m/min]

G97 = direct speed programming (R.P.M.)

drilling, milling or other tools, whose diameters do not alter during machining, are operated at a constant speed. it is also advisable to work at a constant speed when threading. The adjacent formula is used to calculate the speed.

n = Speed in rpmVc = Cutting speed in m/min (255)d = diameter in mm (18,0)

Example: G97 S4509 s [rpm]

6. iSO programming

23

G92 = Speed limitation

The function “G92” together with the address “S” bring about a speed limitation. Very high speeds occur when turning at a constant cutting speed, particularly when facing in the direction of the work spindle centre (X axis). Where parts are unbalanced even a relatively low speed can be dangerous.

Example: G92 S3500 s [rpm]

The address “S” is used for three different functions. The corresponding G function assigns constant cut-ting speed, direct speed or speed limitation. The G function and the S command must be in the same block.

G94 = Feed in mm/min

G94 programs the feed in mm/min for drilling or milling tools. The adjacent formula is used to calculate the feed in mm/min:

Vf = Feed in mm/minn = Speed rpm (4509)Z = number of teeth (for drill bit 1)Sz = Feed per tooth mm/tooth or mm/rev (0.25)

Example: F1127 F [mm/min]

G95 = Feed in mm/rev

G95 programs the feed in mm/revs for general lathe tools. These tools work at different diameters of the workpiece. The speed of the work spindle changes due to the constant cutting speed at the tool tip. The feed per revolution, however, remains the same.

Example: G95 F0.25 F [mm/revs]

M codes (auxiliary functions))

M codes are characterised as auxiliary functions, with whose help the greatest range of machine actions can be triggered. M functions are standardised to some extent and are hence the same in all CnC machine tools. There are also free M functions, which are used differently by each machine manufacturer. Please pay particular attention here to the operating instructions of the machine manufacturer. The most important M functions are listed below:

M00 = Program stop unconditionalM01 = Program stop optionalM03 = Work spindle On, clockwiseM04 = Work spindle On, anticlockwiseM05 = Work spindle STOPM07 = Coolant 1 OnM08 = Coolant 2 OnM09 = Coolant OFFM30 = Program end with resetting to program startM98 = Subprogram call-up

24

“MaNual GuIde i ” program and G codes

a program created by “Manual Guide i” is displayed in the following illustrations:

On the left, the entire program for the previous example “workpiece contour”, with the contour roughing and finishing.

The actual workpiece contour is saved as subprogram no. 71. in this way the contour description data can be used for roughing and finishing.

Only the sentences marked in yellow are entered in iSO code. They have the following meaning:

G92 S4000: Programmable speed limitation (G92) to a max. (S) 4000 rpm.

G0 X200 Z200 T0202: Rapid feed (G0) of the axes X and Z to X200 Z200, change position and tool function no. 2 with tool offset no. 2 (T0202).

G96 S100 M4: Constant cutting speed (G96) (S) 100 m/min and spindle On in an anticlock-wise direction(M4).

G0 X200 Z200 T0: Rapid feed (G0) of the axes X and Z to X200 Z200 and delete tool offset no. 2 (T0202).

M30: Program end and reset program to start.

These blocks are repeated practically in every program, tool replacement is even repeated several times. at the most, it is the tool number, speed and cutting speed that change. These entries are thereby optimally suited to be stored as a template whereby they can be called up as required, at the press of a key, from the start menu.

6. iSO programming

25

Tool offset allows you to program workpieces without having to take into conside-ration differing tool dimensions.

The tool offset usually refers to a reference tool that was used to determine the workpiece zero point.

Tool memoryrThe CnC controller has a tool memory which contains various tool-related data. The memory contains data on the type and shape of the tool as well as offset for the X and Z axes, radius and virtual tip positi-on. Below you will see tools for general turning, threading, grooving as well as tools for contour turning:

if the machine is equipped with the so-called powered tools for drilling and millingthen the tools for these operating modes are also available.

The adjacent tool list contains the offset for the X and Z axes, the radius and virtual tip position

as well as the tool shape and type.

7. Tools and offsetting

26

The mounting position of the toolas well as the geometric values for the tool angle for general tools, the width and possible grooving depth in the case of grooving tools, the dia-meter and tip angle of drill bits etc.

Creating a MaNual GuIde i program

a Manual Guide i program is created in the following steps. You must pay particular attention to the correct approaching of the cycle start point and returning to a defined withdrawal point.

1) Blank part definition (only if a program simulation is required)

2) approaching the tool indexing point

3) Tool selection

4) inserting the required G and F functions (e.g. spindle On, speed, coolant, feed)

5) approaching the cycle start point

6) Cycle: Cutting conditions (e.g. turning, drilling, thread cutting, grooving)

7) Cycle: Figure information (several figures e.g. drilling figures can be programmed after a cycle)

8) Moving to a defined withdrawal point

9) Repeating steps 2 to 8, to add additional machining processes

10) Program end, enter the required M and G functions

nOTe:activities described at point 5 can be executed in advance (between points 2 and 4) according to the operator needs.
