An Experimental Study of the Effects of Electrode Shapes on Micro-EDM Performances

摘要：

　　In this paper, experiments were conducted to investigate the effects of cylindrical electrode and helical electrode on the micro electrical discharge machining (EDM) performances during micro-hole machining of titanium alloy.The results show that the material removal rate (MRR) and the tool wear rate (TWR) increase with open circuit voltage, regardless of electrode shapes.Compared to the cylindrical electrode, helical electrode can result in higher MRR and lower relative tool wear ratio (RTWR).It can be concluded that the helical electrode is more suitable than cylindrical electrode for machining micro parts.
