BEGIN PGM 360511 MM ................................... Begin program; program number 360511; dimensions in
millimeters
1
BLK FORM 0.1 Z X+0 Y+0 Z–20
2
BLK FORM 0.2 X+100 Y+100 Z+0 ..................... Define blank form for graphic workpiece simulation
(MIN and MAX point)
3
TOOL DEF 1 L+0 R+5
4
TOOL CALL 1 Z S1000 ....................................... Define tool in the program; call tool in the spindle axis Z;
spindle speed S = 1000 rpm
5
L Z+100 R0 FMAX M6 ....................................... Retract in the spindle axis; rapid traverse; insert tool
6
L X–10 Y–10 FMAX ............................................. Pre-position in X and Y; rapid traverse
7
L Z–10 FMAX M3 ............................................... Move to working depth; rapid traverse; spindle on with
clockwise rotation
8
L X+5 Y+5 RL F100 ............................................ Move to first contour point – corner point 1 – with radius
compensation (RL) and reduced feed rate (F 100)
9
L Y+95 ................................................................ Move to second contour point – corner point 2: all values that
remain the same as in block 8 need not be re-programmed
10
L X+95 ................................................................ Move to third contour point – corner point 3
11
L Y+5 .................................................................. Move to fourth contour point – corner point 4
12
L X+5 Y+5 .......................................................... Conclude milling, return to first contour point
13
L X–10 Y–10 R0 FMAX ....................................... For safety reasons, retract in X and Y; rapid traverse
14
L Z+100 FMAX M2 ............................................. Move tool to setup clearance; rapid traverse;
spindle off, coolant off, program stop,
Return jump to block 1
