Anandkumar Nikalje

Abstract

Electric discharge machining (EDM) is a cutting-edge machining technique that has been extensively applied to machining difficult-to-cut elements in a variety of industry sectors. It is a non-conventional material removal technology capable of accurately machining complicated forms and morphologies. The EDM method works on the principle of using thermal-electric energy to degrade electrical elements using quickly recurring sparking technique between a non-contact electrode and a titanium Ti-6Al-4V work piece. The MRR (material removal rate) is low and surface finish is poor.to overcome this powder mixed in dielectric fluid is used to increase its conductive strength which is PMEDM (powder mixed EDM). This work provides a thorough evaluation of research investigations on the Electric discharge machining of titanium Ti-6Al-4V workpiece. First, we discuss the characteristics of titanium alloy. Secondly, EDM is discussed with its basic working and types. Next critical analysis of surface integrity in relation to EDM is discussed. Then this work summarizes practical and theoretical EDM investigations targeted at improving process performance, such as MRR, surface roughness, surface morphology, recast layer and residual stress. Furthermore, the study highlights current EDM challenges as well as directions for future research.
