The system adopts CPU board with fast processing elevator operational program, data signal exchange, and HMI screen, which can make sure reliable operation and high speed. It also has PHILIPS SJA1000T field CAN bus, 82C251 Bus interface and the latest serial storage technique to record data. The functions of external watchdog and control chip internal watchdog compose two-level procedure monitoring, so as to ensure the normal operation of the control program. Heavy-current switch power LM2576 ensures the stable system working power, which has low requirements for the power supply. High-speed optoelectronic isolator and internal frequency division technology can make NW3P08-41C (42C) CPU receive the input impulse up to 1-phase 100 KHZ*2 CHANEL or 2-phase 50KHZ*1 CHANEL 32bit.

GA often uses C or Visual C++ to compile codes, so the program is not only long and cockamamie but also the efficiency is low and the velocity is slow. This paper uses software Matlab powerful calculating ability and many functions to compile programs, then encapsulate and link those programs to run without Matlab environment. At last use Visual C++ friendly alternate function to compile in-out interface.

针对遗传算法常用C或Visual C++编写源代码，程序庸长繁琐，效率不高，运行缓慢的特点，本文采用Matlab强大的数值计算能力和众多的库函数编写算法；然后封装和链接程序，使Matlab编写的算法能够完全脱离Matlab的编程环境；利用Visual C++良好的人机交互功能，用Visual C++编写算法的输入输出接口界面。

Adopting this method, a series of face milling cutters have been developed, which are more accurate than the products that are programmed by labor.
