Abstract
Numerical control technology is a highly technicalwork, especially in the field of mechanical processing, the mostwidely used, so this requires the employeeswith avery high knowledge of machining process, NC programming knowledge and numerical control operation skills.
At the beginning of this design, the development of NC machining technology is explained. In the second chapter, the part drawing is analyzed to understand the product structure and size. The third chapter mainly describes the parts needed to be processed and the machining methods, selects the parts blank, selects the positioning datum and machining process route of the parts, and selects the machining machine tools and the tools used. At the end of the chapter, the cutting parameters of the cutting tool are determined, and NC machining process card is filled in. In the fourth chapter, the programming method of parts is selected,which is automatic programming. This paper describes how to create geometry and tools in UG software. Then it tells the story of Ping. Surface milling operation, drilling operation, cavity milling operation, complete parts processing. In the last chapter of the article, the parts are processed by simulation to ensure that the cutting path and process arra
Keywords: NC programming, processing technology, UG software, programming, modeling.
