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 d...
