Example: Interpolation Turning Cycle 292

The following NC program illustrates the use of Cycle 292 CONTOUR.TURNG.INTRP. This programming example shows how to machine an outside contour with the milling spindle rotating.

Cyc292_1
  • Program sequence
  • Tool call: Milling cutter D20
  • Cycle 32 TOLERANCE
  • Reference to the contour with Cycle 14
  • Cycle 292 CONTOUR.TURNG.INTRP.

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.

 
Tip

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.
