WEDM is a one of the non-conventional machining processes used for machining complex shape components and hard materials to produce intricate shapes on the wide variety of materials. With the increasing demands of high surface finish and high rate of MRR of complex shape geometries, WEDM machining process is now being replaced by non-traditional machining processes. According to this paper, opt...

Wire electrical discharge machining (WEDM) is a special form of traditional electrical discharge machining in which the electrode is a continuously moving conducting wire. The mechanism of metal removal in wire electrical discharge machining involves the complex erosion effect from electric sparks generated by a pulsating direct current power supply. The sparks generated between two closely spa...
