NC technology and the widespread application of NC machine tools, machinery manufacturing to the industrial structure, product variety and quality and production methods brought about a revolutionary change. NC machine tool processing workshop is the most important modern equipment. It is the development of information technology (1 T) and manufacturing technology (MT) with the result of the development. Modern CAD / CAM, FMS, CIMS, agile manufacturing and intelligent manufacturing technology, are built on the technology in the NC. NC master modern technology of modern machinery and electronic knowledge is essential to professional students. The design of the content on the characteristics of the CNC processing and analysis of the general steps NC programming. And through ball shaft parts on the process of analysis a correct solution components in processing process localization. Clamp as well as craft route arrangement. Questions and so on craft size determination, guarantee components processing quality The academic society uses the graph data as well as t
