英文摘要：

In order to evaluate the possibility of manufacturing micro cutter with electric spark forming, and fully understand the rules of machining the micro cutter with EDM, the experiments studying on the surface roughness and etching efficiency with two kinds of materials is performed. The reason of difference on surface roughness between micro-EDM and conventional situation is analyzed. Based on the result of the research, it is educed that the micro-electric spark forming is adapted to manufacture micro cutter.
