Lathe Screwcutting Idea
John Hill:
I suppose one could start the carriage moving at an instant synchronised with a single contact on the spindle, advance the carriage the required distance, retact the tool, reverse the carriage the same distance, advance the tool, restart the carriage again at a time triggered by a spindle contact.
Providing the pulses to move the carriage were synchronised to spindle speed the process seems almost trivial, I am probably missing something. :coffee:
Weston Bye:
What John describe is precisely what happens with a CNC lathe. There are a couple of them where I work that turn, face and single point threads on a part all at the same fast spindle speed. The threading takes 6 or 7 passes of the tool and moves back and forth in the motions John describes to thread a section about 3/8" long faster than I can brush my teeth.
Powerful motors are used, as the tool holding axis is massive and supports multiple tools.
