Study on Powder Mixed Elecrtical Discharge Machining Process: A Review

Abstract

Powder mixed electric discharge machining (PM-EDM) process is a hybrid machining process by which the required profile is attained using thermal energy of sparks between tool and workpiece with addition of powder in dielectric fluid at low pulse energy. PM-EDM process enhances the capabilities of EDM process on machining of difficult to cut materials. This chapter explores the findings of research work carried out so far in the domain of PM-EDM of different hard and conductive materials. The effect of aided conductive powder into the dielectric fluid, electrical and non-electrical EDM process parameters on performance characteristics for machining various advanced materials has been studied under this chapter. This chapter also reviewed the industrial and academic work performed by various researchers from the origin to development of PM-EDM over the past decades. The research findings with major challenges along with the future scope have also been paved out.

An insight on Powder Mixed Electric Discharge Machining: A state of the art review

“…84,88,89 A progressive method in the flank of the augmentation of the capabilities of conventional EDM process is Powder Mixed EDM. 90,91 Padhee et al 92 presented the contrast between EDM and PMEDM while using paraffin as a dielectric. It was observed that the MRR was higher for PMEDM as compared to conventional EDM.…”
