Electric Discharge Machining and its Process Parameters: A Review

Vishal Pathania

Abstract


Electro-discharge machining (EDM) process is used in industry for high precision products It involves non-conventional and non-contact machining operations. EDM is known for melt any electrically conductive material regardless of its hardness. EDM results depend on thermal conductivity, electrical resistivity, and melting points of the materials. The tool and the workpiece are adequately both immersed in a dielectric medium, such as, kerosene, deionized water or any other suitable fluid. This study provides an important review on different types of EDM, Classification of EDM dielectrics and characteristics of EDM process and its process parameters.
