| Outline of Final Research Achievements |
I developed a new method combining the advantages of ED-milling and WEDM/WEDG. It is named WED-milling (wire electrical discharge milling). In this method a wire guide with a hemisphere tip is used.
In this study, some method to stabilize a machining state was examined. The assisting electrode method was improved. Furthermore, a new electrical discharge wave form control system was applied, and the stable machining for functional ceramics was realized.

| Academic Significance and Societal Importance of the Research Achievements |
この加工手法では、従来の放電加工法では実現できなかった工具形状が変化しない形彫放電加工を実現できる。さらに、本研究では補助電極法を適用することで、放電が発生しないため加工の対象外と考えられてきた機能性セラミックスに対する加工を可能とする。当該材料に対する安定した加工が実現でれば、その工業的価値が極めて高くなる。
