0 Overview At present, the application of CNC lathe is increasingly popular, more and more types of machining parts, how to improve machine efficiency, shorten the processing time is a topic worthy of further study. Here is an example of using a CNC lathe for machining male and female starting ends. The machine used CK6140, CNC system for SINUMERIK802S. 1 parts of the process analysis and programming points As can be seen from Figure 1, the parts require external surface machining, the thread, the process requires the processing of thread starting point to 1/3 thread (Figure 2A → B → C part of the thread). General processing technology with ordinary lathe or CNC car
