Cycle Call select key (Non-Modal)

Activates the last Modal Canned Cycle Definition (Not Data Definition)

Label Set select key (LBL ?)

Sets a Label around information which may be repeated. Label number

must be a unique number up to 3 digits long and the information followingthis label start must be finished with LBL 0.

Label Call select key (CALL LBL ?)

Calls the required LBL ? and prompts the programmer for the amount of

required repeats.

NOTE: There is a procedure to how this works safely. If no repeats are necessary

the Call LBL ? can be input anywhere in the program. If there are repeats on the

Call LBL ? and do not follow straight after the specified label LBL 0 line then

the Call LBL ? MUST be enveloped around its own Label ?, the repeats taken

away from the repeated Call LBL ? line and then added to the 2nd Call LBL ?

with the same repeats less one. (As Follows)

LBL 1

LBL 2

CALL LBL 1 (label requires repeating 10 times)

LBL 0

CALL LBL 2 REP 9 (9 times repeat because LBL 2 has been read once)

The easiest alternative is to program the CALL LBL 1 with no repeats 10

individual times one after the other or to ensure that the label is written in the

program after the program end M2.

Cutting Condition Commands

Cutting conditions should be carefully examined when preparing a program, since

these conditions greatly influence cutting efficiency and accuracy. The cutting

conditions that determine the rate of metal removal are the Cutting Speed, theFeedrate, the Depth of Cut & the Width of Cut. These cutting conditions and

the nature of the material to be cut determine the power required to take the cut. The

cutting conditions must be adjusted to stay within the power available on the machine

tool to be used. These conditions also effect the tool life, which would need

consideration.

The following cutting conditions are required for all tooling used:

Spindle Speed R.P.M. (Revolutions per Minute)

Designated with an S command.

400 rpm S400

Formula

R.P.M. = Constant Surface Speed (C.S.S.) x 1000

x Diameter

C.S.S. can be found in all manufacturers tooling guides.

Feedrate mm/min. , inch/min. , feed/tooth, feed/rev.

Designated with an F command.

400 mm/min. F400

Formula

Feed = Number of teeth x feed/tooth (pitch) x R.P.M.

Feed/tooth can be found in all manufacturers tooling guides.

M00 Program Stop:After executing the block where the M00 is commanded, automatic operation stops

the machine including the feed, spindle and coolant. Pressing the Cycle Start button

resumes all operations.

M01 Optional Program Stop:

M01 is identical to M00 but is actioned by a switch in the screen. When this switch is

ON then the code acts as M00, but when the switch is OFF the code is ignored

and operation continues as programmed. Applications include: Checks on dimensions,

Checks on tools and to remove chips during machining.

Pecking (Cycle 1)1)The tool drills from the Current Position to the first PECKING DEPTHat the

programmed FEED RATE F.

2)When it reaches the first pecking depth, the tool retracts in rapid traverse FMAX

to the starting position and advances again to the first PECKING DEPTHminus

the advanced stop distance t.

3)The advance stop distance is automatically calculated by the control:

At a total hole depth of up to 30mm :t = 0.6mm

At a total hole depth exceeding 30mm :t = hole depth / 50.

Maximum advanced stop distance = 7mm.

4) The tool then advances with another infeed at the programmed FEED RATE F.

5) The TNC repeats this process (1 - 4) until the programmed TOTAL HOLE

DEPTHis reached.

6) After a DWELL TIMEat the bottom of the hole, the tool is returned to the

starting position in rapid traverse FMAXfor chip breaking.

NOTE: Program a positioning block for the starting point (hole center) in the

working plane with RADIUS COMPENSATION RO.

Program a positioning block for the starting point in the tool axis (SET-UP

CLEARANCE above the workpiece surface).

The sign (+ or -) for the cycle parameter TOTAL HOLE DEPTH determines the

working direction.

SETUP CLEARANCE - (Incremental) Distance between tool tip (at startposition) and workpiece surface.

TOTAL HOLE DEPTH - (Incremental) Distance between workpiece surface

and bottom of the hole (tool tip).

PECKING DEPTH - (Incremental) Infeed per cut. The tool will drill to the

Tapping with chip breaking (Cycle 209)1)The TNC positions the tool in the tool axis at rapid traverse FMAXto the SET-

UP CLEARANCEabove the WORKPIECE SURFACE COORDINATE. There

it carries out an orientated spindle stop.

2)The tool moves to the programmed infeed depth, reverses the direction of the

spindle rotation and retracts by a specific distance or completely for chip release,

dependant on the definition.

3)It then reverses the direction of spindle rotation again and advances to the next in

feed depth.

4) The TNC repeats this process (2 3) until the programmed thread depth is

reached.

5) The tool is then retracted to SET-UP CLEARANCE, and if programmed, to the

2ND CLEARANCE withFMAX.

6) The TNC stops the spindle turning atSET-UP CLEARANCE

Linear Pocket Milling (Cycle 4)1)The tool penetrates the workpiece at the starting position (pocket center) and

advances to the first PECKING DEPTH.

2)The cutter begins milling in the positive axis direction of the longer side (on

square pockets, always starting in the positive Y axis) and then roughs out the

pocket from the inside out.

3)This process (1 - 3) is repeated until the DEPTH is reached.

4) At the end of the cycle, the TNC retracts the tool to the starting position.

Linear Pocket Finishing (Cycle 212)1)The TNC automatically moves the tool in the tool axis to SET-UP

CLEARANCE, or - if programmed - to the 2ND SET-UP CLEARANCE, and

subsequently to the center of the pocket.

2)From the pocket center, the tool moves in the working plane to the starting point

for machining. The TNC takes the ALLOWANCE and the tool radius into account

for calculating the starting point. If necessary, the TNC plunge cuts into the pocket

center.

3)If the tool is at the 2ND SET-UP CLEARANCE, it moves in rapid traverse

FMAX to SET-UP CLEARANCE, and from there advances to the first PLUNGING

DEPTH at the FEED RATE FOR PLUNGING.

4) The tool then moves tangential to the contour of the finished part and, using

climb milling, machines one revolution.

5) After this, the tool departs the contour tangential and returns to the starting point

in the working plane.

6) This process (3 - 5) is repeated until the programmed DEPTH is reached.7) At the end of the cycle, the TNC retracts the tool in rapid traverse to SET-UP


finally to the center of the pocket (end position = starting position).

NOTE: The sign (+ or -) for the cycle parameter DEPTH determines the working

Slot Milling (Cycle 3)Roughing Process

1)The TNC moves the tool inward by the milling allowance (half the difference

between the slot width and the tool diameter). From there it plunge cuts into the

workpiece and mills in the longitudinal direction of the slot.

2)After downfeed at the end of the slot, milling is performed in the opposite

direction. This process is repeated until the programmed MILLING DEPTH is

reached.
