We have a part that we are making on our CNC lathe (Feeler FTC-200L with a Fanuc Oi-TD controller) that has a 7/16-14 UNC threaded section on one end. I am using the G76 command to cut the threads, but I am getting a burr on the lead in. I tried to increase the size of the chamfer on the part before I thread, but the thread tool pushes material out so the nut won't go one. Is there a way to chamfer with the thread tool in the G76 step to get more of a tapered lead in?
