A 3-axis micro-milling machine tool composed of linear motor, air high-speed static-pressure electro-spindle and motion-control card DMC-1842 is developed; the CNC system of the parallel double CPU based IPC and Windows operating system is constructed. The application software of CNC system is exploited by modularized mind in C # programming language, reasonable human-computer interface is designed. Finally, in order to validate the performance of the micro milling machine' s CNC system, the miniaturized parts are machined by the 3-axis micro milling machine. Through these test analysis, the hardware and software architecture of the CNC system is verified to meet the requirements of the micro milling machine ; micro milling process is also proved to be feasible and applicable.
