First of all utilize UG software CAD module to adjust the spare parts which will be processed and carries on the three-dimensional entity modeling, and then discusses the method, process, and processing techniques of the three-dimensional entity modeling of the spare parts. Based on the analysis of the shape and structure of the spare parts, this article develops their processing technology and analyzes the methods and characteristics of numerical control automatic programming. By using the CAM module of UG, it completes the NC programming of rough machining, semi-finishing, and finishing, and performs cutting simulation processing on the generated operations to check the correctness of the operations. Finally, post-processing is carried out on the generated operations to generate NC code programs that can be recognized by the CNC machine tools. Keywords: UG, CAD, CAM, automatic programming
