Review of Research Work in Nano powder Mixed Electric Discharge Machining

Nanopowder mixed Electrical discharge machining (NPMEDM) is a non-conventional machining process used to manufacture intricate profiles, complex cavities in dies and molds, machining of advanced materials that are extremely difficult to machine by conventional machining processes. In recent years, researches have emphasized on machining of workpiece material after the addition of nano particles into the dielectric fluid of EDM. This technology is termed as NPMEDM. This article presents a review of ongoing research and development in NPMEDM. The critical analysis of the use of powders for micro and nano machining is also presented. The last part of the article discusses the future research directions.
