Abstract In this text, the NC system control program, communication interface and circuit diagram designed by self are released, which combine with CNC ISO standard. The system is provided with closed loop control of the work current, closed loop adjusting of the work voltage, and computer aided program. The system is not only satisfied with the Electrical melting and Explosion Machine Tool, but also can be used in usual two coordinate machine tools, which has open loop control of feed speed and displacement.
