Example: turning, simultaneous finishing

The following NC program illustrates the use of Cycle 883 TURNING SIMULTANEOUS FINISHING.

  • Program sequence
  • Tool call:Turning tool
  • Start turning mode
  • Move to safe position
  • Call the cycle
  • Reset the coordinate system with Cycle 801 and M145

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.
