Out of all the machining processes used worldwide, Electrical discharge machining (EDM) is one of the most commonly used processes for material removal from a surface. It is a process for shaping hard metals and forming deep holes by subsequent erosion, which can be done in all kinds of materials which can conduct electricity. In this process, erosion occurs when electric discharge takes place in a small gap between the work piece and the electrode; this removes the unwanted material from the parent metal through melting and vaporizing in presence of dielectric fluid. In recent years, researchers have explored a number of ways to improve Electrical Discharge Machining process parameters such as Electrical parameters, Non-Electrical Parameters, Tool based parameters & Powder based parameters. This paper reviews and outlines the research work carried out in the recent years and also discusses the scope for future research work in the field.
