ABSTRACT

Numerical control technology and CNC machinery manufacturing industry in today's huge benefits and the important position in the country, and shows its strategic role in modern industrial base, and has become a traditional mechanical manufacturing industry upgrading transformation and automation, flexibility and integrated production of important means and logo. Numerical control technology and the wide application of nc machine tools, machinery manufacturing industry structure, product categories and class and production brought the revolutionary change. CNC machine is the most important modern processing workshop equipment. It is the development of the information technology （1T）and manufacturing technology development （MT）. Modern CAD/CAM, FMS, CIMS, agile manufacturing and intelligent manufacturing technology, are built in the numerical control technology.

CNC equipment manufacturing is the machine tools, techniques and equipment manufacturing is the cornerstone of modern hi-tech industry development is the guarantee of the modernization of national defense and the strategic equipment. In the global advocate green manufacturing environment, nc reform has become hot. It includes ordinary numerical control machine tool CNC transformation and upgrade.

This design is introduced the contents of nc machining process and characteristics, and analysis of CNC programming. And through certain examples of detailed introduced nc machining process analysis method.

Keywords:CNC，technology process，programming
