Numerical control technology, is the method that USES digital control of one of the working process of automatic control technology. It is usually controlled by the position, Angle, speed and other mechanical quantity and amount related to the mechanical energy flow switch. Numerical control depends on the data carrier and the binary form data operation. And CNC milling machine is in the common milling machine used digital control system, can be under the control of the program code accurately for milling machine.
This article for programming and machining of the parts, through the processing of CNC milling machine, for specific parts of the process of analysis, the scheme of machining tool and cutting parameter selection, determine the processing order and processing route, the nc machining programming. This article mainly from the construction of the 3 d model, processing technology analysis and the general steps of machine tool programming, improve my understanding of the use of CAD/CAM software and figure drawing, improve my reading ability. Finally, automatic programming and processing, the hope can find better ways of programming and processing in the process method, improve efficiency, and applied to real work can further understand the machining characteristic of nc machine tools.
KEY WORDS: CNC milling machine, cooperate with parts, 3 d model, processing technology, automatic programming
