| Outline of Final Research Achievements |
This study proposes the simultaneous machining of polygonal microelectrode and microholes using tandem EDM mechanism. Two types power sources for forming polygonal pillar electrode and hole machining were installed on the same machine. These process are carried out at the same time. A mask plate with the target shape is used for forming electrode. Planetary motion was applied to the mask plate and the polygonal micro pillar electrode was produced by this reduced scale process. In this process, low wear condition of the mask plate and high wear condition of the electrode were chosen. After the electrode was forming, polygonal microholes were drilled into the tungsten material using this electrode. In order to perform simultaneous machining of a microelectrode and microholes, a tandem structure mechanism was constructed. Continuous polygonal microhole machining was attained by applying the tandem EDM mechanism under the appropriate conditions.
