To improve the lower precision and the stability of the domestic EDM CNC system ,the research developed the high-speed and high-precision EDM CNC system which on the basis of the modern PC platform and NC controller. In this system ,a PC and Windows operating system was employed as the principal computer, and the PCI,DSP,FPGA was employed as the subordinate computer. It was able to achieve multi-axis orbital machining and high-speed complex jump machining. By being applied to EDM machine and carrying out the experiments of jump and multi-axis orbital machining,the system validated its performance of high stability and reliability.
