Summary
Details
A multi-start thread is cut in a Thread Milling operation. One tool can only cut a single thread per pass while another can cut multiple threads. What setting is used to accommodate these two tools?
When a thread tool that cuts only one thread at a time is used to cut a two-start thread, as an example, the tool will need to cut twice. Below is a picture of the part while cutting the first pass and then while cutting the second pass.
If a thread tool that can cut two threads per pass is used to cut the same thread than only one pass will be needed.
To get NX to cut two threads at the save time set the (FL)Flute Length to two times the (P)Pitch. To cut a single thread per pass set the (FL)Flute Length to the same value as the (P)Pitch.
