“…Moreover, usage of graphite powder helps to decrease the machining time by 5 times and increase the vibrational speed of electrode tool by 3 times. Chromium micro powder was used by Ojha et al [91] in machining EN-8 Steel. In addition to this, researchers also studied the impact of electrode shape on machining.…”

Electrical discharge machining (EDM) is an advanced machining method which removes metal by a series of recurring electrical discharges between an electrode and a conductive workpiece, submerged in a dielectric fluid. Even though EDM techniques are widely used to cut hard materials, low efficiency and high tool wear remain remarkable challenges in this process. Various studies, such as mixing different powders to dielectric fluids, are progressing to improve their efficiency. This paper reviews advances in the powder-mixed EDM process. Furthermore, studies about various powders used for the process and its comparison are carried out. This review looks at the objectives of achieving a more efficient metal removal rate, reduction in tool wear, and improved surface quality of the powder-mixed EDM process. Moreover, this paper helps researchers select suitable powders which are exhibiting better results and identifying different aspects of powder-mixed dielectric fluid of EDM.

“…I P was most influential parameters for MH, while kerosene produced better results than EDM oil as the dielectric fluid. Ojha et al (2011) and Garg and Ojha (2012) machined EN-8 steel with Cr powder added to dielectric using EDM process. Optimum parameters for MRR, SR and TWR were performed using response surface methodology.…”

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.
