Review on Surface Modifications of the Workpiece by Electric Discharge Machining

The recent times have seen an expanding enthusiasm for the novel uses of electrical discharge machining (EDM) method, with specific accentuation on the capability of this procedure for surface modification. Other than the disintegration of work material amid machining, the inborn idea of the procedure results in the expulsion of tool material too. Through either dispersing metallic powders in the dielectric or by utilizing composite or both intentional material exchanges might be done under explicit machining conditions. In this review paper, secondary use of EDM is discussed which has revolutionized the concept of surface modification. A review of the wonder of surface adjustment by EDM and future potential applications has been presented in this paper.
