Centerline Drilling siemens NX

Use Centerline Drilling to perform drilling operations with a non-rotating tool on the lathe spindle centerline with the workpiece rotating.

The centerline drill operation supports two different types of cycles:

  • Controller (canned) machine cycles — The system outputs one cycle event containing all cycle parameters and a single GOTO statement representing the start position of your NC machine-specific drilling cycle.

  • Simulated machine cycles — The turning processors compute a centerline drilling tool path. The system outputs a series of GOTO statements and no CYCLE event.
