abstract<br>The formulation of NC turning scheme is one of the important contents of making turning process specification. This design is based on the process method of NC turning, arranging the sequence of processes, determining the selection of cutting tools and cutting parameters. According to the design idea, this paper summarizes some comprehensive technological principles of the NC turning process, and puts forward the design scheme combined with the design and processing of the screw shaft, and makes a comparative analysis.<br>In the process of NC machining, we often encounter the processing of screw shaft. Based on the analysis of the processing technology of a screw shaft part, we compile the NC machining program, check the correctness of the NC programming and various processes, and provide a very meaningful reference for the NC machining of this kind of parts.<br>Key words: NC lathe, NC turning process, thread processing part drawing, process analysis
