Example: Program various depths with OCM cycles
The following NC program illustrates the use of OCM cycles. You will define one pocket and two islands at different heights. Machining includes roughing and finishing of a contour.
Program sequence
- Tool call: Roughing cutter (Ø 10 mm)
- Program CONTOUR DEF
- Define Cycle 271
- Define and call Cycle 272
- Tool call: Finishing cutter (Ø 6 mm)
- Define and call Cycle 273
- Define and call Cycle 274
