In NC, from parts of the design drawings to finished parts qualified to deliver, not only to consider the establishment of NC program, but also taking into account the processing routes such as the arrangement of parts, machine tools of choice, the choice of cutting tools, spare parts processing The positioning fixture and a series of factors, at the beginning of programming before, must be on the part design drawings and technical requirements detailed analysis of NC machining process in order to finally determine which is the key technology components, which are difficult for NC machining, and ease of NC programming. Machining of parts of the preparation of numerical control program of the most important and most complex part, CNC machining process design is the core of the work must be completed before the NC programming. A qualified programmers of CNC machine tool and control system functions and features, and influence every aspect of NC should have a clear and comprehensive understanding, so as to avoid the process plan as ill-considered product quality that may occur problem, resulting in unnecessary human and material resources, waste of resources.
