High speed and high precision processing technology can greatly improve efficiency, improve the quality and grade of products, shorten production cycle and enhance market competition ability. For the nc machining, manual programming or automatic programming before will be made of parts manufactured by technology analysis, drafting processing scheme, choosing the appropriate cutting tool and cutting parameter is determined, to some process problems (such as the cutting point, processing route etc.) also need to do some processing. And master the methods of control accuracy in machining process, can produce qualified products. In this paper, according to the characteristics of the nc machine tool, in view of the specific parts, process analysis, scheme of equipment, cutting tool and cutting parameter selection, determine the processing order and processing route, the nc machining programming. Through the whole process of the process, fully embodies the nc equipment in the guarantee machining accuracy, efficiency, simplify the working procedure such as advantage.
