전극 소재에 따른 방전가공 특성에 관한 연구

A study on the characteristics of EDM with the electrode materials

In this study, the characteristics of Electrical Discharge Machining (EDM) with the electrode materials were investigated. EDM experiments have been carried out on electrodes with eight different copper-based and graphite-based materials. From the results, the copper-based electrodes showed excellent surface roughness than the graphite-based electrodes. But graphite based electrodes have advantages in economic aspects.
