Current Research Trends of Electrical Arc Machining (EAM) with Reference to Electrical Discharge Machining (EDM)

Abstract

thermal energy-based unconventional machining technique known as "electrical arc machining" uses arc energy to melt and vaporize work piece material. Advanced materials including metal matrix composites, super alloys, and conductive ceramics may be efficiently machined by electrical arc machining. When it comes to the pace of material removal, the procedure is thought to be more effective than the majority of other non-traditional machining techniques. However, it is constrained since it produces a very subpar surface finish. Other limitations include the rate of tool wear, the formation of recast layers, surface and subsurface cracks, and, to some extent, geometrical accuracy. The research that has been done so far in the area of electrical arc machining is thoroughly analyzed in this work. The article summarizes the thorough practical and theoretical investigations on electrical arc machining that have been carried out in order to elucidate the consequences of various input control parameters on various quality attributes. The study's final section looks at possible directions for future work in electrical arc machining. Additionally, it contains past modeling and optimization research in this area.
