Study on realization of the tool movement envelope for thefine ceramics by electrical discharge machining

对绝缘Si_3N_4陶瓷进行了放电成形研究。并对绝缘Si_3N_4陶瓷电火花加工中的电极材料进行了考察。此外，我开发了导线放电铣削法（wedd铣削法）利用导线导轨往复旋转运动。不需要考虑工具电极的磨损，因为我们通过这种方法使用导线作为工具电极。

Electric discharge forming for insulating Si_3N_4 ceramics was carried out in this study. And the electrode material in the electrical discharge machining to insulating Si_3N_4 ceramics was examined. Furthermore, I developed the wire electrical discharge milling method (WED-milling method) using wire guide with reciprocating rotary motion. It is not necessary to consider the wear of the tool electrode because we use a wire for a tool electrode by this method.
