This paper introduces the computer control method and electric sparkle processing technology applied to grind shaping. It is utilizing the high purity graphite for electrode, making electrode to promised shape. This method can finish the workpiece process by controling electrode movement to workpiece and pulse parameter, can greatly reduce the effect to precision and roughness caused by electrode wear down. Utilizing these method and technology, the problems of shaping hard, breakable, deformable workpiece can be solved. It gives a formula for calculating loss of electrode radius.
