Recently evaluated Electrical Discharge Machining (EDM) process performances: A research perspective

Abstract Recently, cutting edge machining approaches are used extensively for answering multifarious issues in manufacturing sectors that consist of machining larger strength materials, manufacture of intricate shaped profiles, improve surface characteristics, and lower production time. In this scenario, the development of Electro Discharge Machining (EDM) is rapidly taking place. EDM is a non-conventional thermal-based machining procedure that is used for the machining of harder materials. At large, spark erosion is the main working principle performed in EDM. This meticulous review study provides based on the recently published EDM process articles where the objective is to attempt newer work material and advanced electrode that could significantly meet industrial manufacturing domain around the globe. In addition, the concluding observations turn out with defined underlines and technological research gaps making this review article useful to related academic and scientific research community with proper identification of EDM process factors, advance work materials, material electrode tools and sustainable dielectric for achieving favorable outcomes as a frontier machining technology.
