Study of Combined Process in Micro-EDM

Abstract

Micro-EDM is a flexible process which has many technique methods such as forming, drilling, milling, copying and WEDM. Combined these methods together can enhance the EDM machining ability. In this paper a set of route design regulations used in combined machining is proposed. Through these regulations, the optimal route of combined process can be obtained which can improve high machining quality and efficiency. To test performance of the regulations, the combined route of a micro part is designed and its fabrication is performed at last.
