Process analysis is to analyze the rationality of the processing requirements of the parts according to the drawings, and at the same time determine the clamping mode of the processed parts on the numerical control lathe, and make a reasonable choice of the surface processing sequence, feed route and dosage of the parts. This is the preliminary preparation stage of turning processing, and the analysis of the process formulation directly affects the subsequent programming, processing efficiency and part processing accuracy. At the same time, the turning process is very strict for the preparation, and the technical requirements for the programmer are relatively high. In order to ensure the degree of rationality and practicality, the programmer is required not only to be familiar with the programming language, but also to be proficient in the working principle, performance and processing technology of the numerical control lathe, so as to ensure the rationality and practicality of the processing technology. Therefore, when analyzing the numerical control turning process, it is necessary to ensure that the processing technology is reasonable and practical according to the characteristics of the numerical control lathe and the processing technology principles.
