Abstract The EDM method is non-conventional in machining for machining of geometrically unpredictable or hard materials and electrically conductive materials that cannot be machined with ordinary forms of machining. With latest strategies, research has emphasized EDM's increased machining efficiency. PMEDM is an ongoing method where a Mixed conductive powder with the dielectric liquid to improve EDM machining capabilities in this direction. This paper introduces the review work done to improve the performance characteristics of machining like MRR, SR and TWR for different Machining parameters like Ip, Duty factor, Ton, Toff, Work piece material, powder type, concentrated powder with different dielectric liquids and powder materials. Also in the paper reports and summaries Current trends in the research, PMEDM using various powders such as Nano powders mixed in dielectric fluids and examined the current challenges, future scope of research and impediments of the PMEDM process.
