Abstract: The numerical control programming technique for high speed milling is a kind of comprehensive technique. It includes a comprehensive factor taking account of many factors. Whether a program is written properly directly influences time spent and quality of device to be manufactured. Employing a good programming strategy suitable for high speed is very important, only so a scientific, excellent, and practical CNC program for high speed milling can be written, and be realized in high speed milling. Thus the high quality of device produced by high speed milling, high yield, and low power consumption are achieved.
