Example: Open pocket and fine roughing with OCM cycles
The following NC program illustrates the use of OCM cycles. You will program an open pocket that is defined by means of an island and a boundary. Machining includes roughing and finishing of an open pocket.
Program sequence
- Tool call: Roughing cutter (Ø 20 mm)
- Program CONTOUR DEF
- Define Cycle 271
- Define and call Cycle 272
- Tool call: Roughing cutter (Ø 8 mm)
- Define and call Cycle 272
- Tool call: Finishing cutter (Ø 6 mm)
- Define and call Cycle 273
- Define and call Cycle 274
NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.
Change the following contents as needed:
- Tools
- Cutting parameters
- Feed rates
- Clearance height or safe position
- Machine-specific positions (e.g., with M91)
- Paths of program calls
Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.
In addition, test the NC programs using the simulation before the actual program run.
With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.
