In modern era precision, accuracy, better surface finish, optimization of time, optimization of cost and optimization of material plays major role in every machining process. To machine complicated geometrical shapes materials which are very hard and not machined by conventional machining process such as Ceramic materials, Composite materials, Heat treated steels, Super-alloys and Carbides are easily machined by Electrical Discharge Machining. Electro discharge machining is a not a conventional machining process and known as non conventional machining process. Electrical Discharge Machines are widely used in variety of applications such as, Drilling of small holes, Mold making, Die casting industry, Tool, Electronics industry, Automobile industry and Aerospace industry. In recent decade many Electrical Discharge Machining researchers developed number of new experiments to study the effect of EDM process parameters like as Spark on time, Spark off time, Peak Current and Voltage to improve and optimize, EDM performances which are rate of material removal (MRR), OC, rate of tool wear (TWR) and Surface finish, related with surface roughness. The focus of all the researchers is to improve Surface finish, less Tool wear and Efficient Material removal rate. This paper reviews the various machining parameters related with EDM from past research works. The selection of electrodes, method of optimization, process parameters and their effects are done in this paper, concluded from previous research works.
