Trying to learn to single point thread g-code and it looks like it's going to be a bit more difficult. The part has a 4-40 OD thread. I'm being told a 16ER 32UN and maybe it was a 16ER 12UN pitch SP insert could be used. How is this done? I'm uncertain on how to do it even with a 16ER 40UN insert. When it comes to SPT I don't understand how the overall speed of the passes is set. What is the limit of the machine? Is the feed, F0.025" if it was a 4-40 insert? (Is this IPR?... If I'm thinking right) Then it goes off of the rpm I'm running? In both X and Z it can rapid over 900IPM. 2500 RPM X 0.025" = 62.5" Rapid. 73~ SFM so the insert should be fine there, but I don't think I've seen threading faster then 800~rpm on a lathe. Am I heading in the totally wrong direction here? I was being told you could technically thread any thread with any insert, but the top of the threads might be slightly off.
