In this CNC programming tutorial, @G-Code Tutor demonstrates how to use G32 to cut straight-shanked and tapered threads.
G32 is typically used to produce single-point threads on a CNC lathe. Unlike other some of the more common thread cutting G-codes, such as G76, G32 is not a cycle. It is classified as a module for a couple of reasons. First because the taper and/or lead can vary continuously throughout the entire thread. Second, because no automatic position return is performed at the end of the threading operation.
In “simple” terms, the G32 command locks in the rotation of the lathe spindle with the feedrate of the tool. So as the spindle rotates one revolution, the feedrate will lock in each time to be able to produce a thread, in a similar fashion as a manual lathe would cut a thread.
