The correct selection of manufacturing conditions is one of the most important aspects to take into considerationin the majority of manufacturing processes and particularly, in processes related to Electrical Discharge Machining (EDM).The principle of Electrical Discharge Machine (EDM) also called electro discharge spark erosion machining is based on the erosion of metals by sparks discharge. Metals are easy to machine by using non-traditional machining such as Electric Discharge Machine (EDM). But, during EDM, with the workpiece, even the tool wears out. This tool wear is not desired as it changes the tool geometry. To overcome this obstruction, cryogenic treatment is carried out for tool material before machining. The machining performances of the process are concluded in terms of Material Removal Rate (MRR), Tool Wear Rate (TWR) and Surface Roughness values. In this paper, the finding of the literature review on “Effect of cryogenic treatment of tool electrode on the performance parameter in EDM” has been presented.
