Thread NC sequences are used to cut threads on a lathe. The threads can be external and internal, blind and through. This NC sequence does not remove any material from the workpiece on the screen. The proper cutter path will, however, be generated.

A Thread NC sequence is defined by sketching the first tool movement, which corresponds to the major diameter for an external thread and to the minor diameter for an internal thread. The final thread depth is calculated using the THREAD_FEED parameter.

Creo NC supports ISO standard thread output as well as AI Macro output.

You can reference geometry of existing Thread cosmetic features, created in Part mode. It is especially convenient for blind threads.
