Along with numerical control technology unceasing development and application domain expansion, CNC processing technology to the peoples livelihood some important professions (IT, automobile, light industry, medical service and so on) development plays more and more important role, for efficiency, quality is the main body of advanced manufacturing technology. High speed, high precision machining technology can greatly improve efficiency, improve the quality and grade of the products, shorten production cycle and improve the market competition ability. For the numerical control (NC) machining, whether manual programming or automatic programming, enrolled ChengQian are to the processing of parts for process analysis, draws up the processing plan, choose the right tool, to determine the cutting dosage, for some technology problems (such as the cutting point, processing route, etc.) also need to do some treatment. And in the process to control the accuracy of the method, we can work out qualified products. In this paper, according to the characteristics of the numerical control machine tool, in view of processing the ashtray parts, the technology scheme analysis, the scheme determination of tools, cutting tools and selection of cutting parameter, determine the processing sequence and p
