Mastercam Lathe Threading Operations

Typically, threading toolpaths are the last toolpaths added to a part due to the increased need for accuracy. Here we will explain how to add an OD thread. Expand the General gallery and select thread from the list. Return to the toolpaths parameter tab and select the proper threading cutter. Typically, threads will be cut at a much lower spindle rpm than most other passes of the same diameter.

The lead value for the thread can be set here numerically. The next step is to define the thread’s outer diameter by clicking the Major Diameter button.
