内容摘要 没有理论指导的实践是盲目的实践，没有实践的理论是空洞的理论。Abstract no theory guidance practice is blind practice, no practice theory is empty theory. 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 processing route, nc machining programming. Through the whole process of the formulation of the process, fully embodies the numerical control equipment in the guarantee machining accuracy, processing efficiency, simplify the advantages of the process. Key words: process analysis theory guide feed line manual programming.
