Abstract: Electrical discharge machining (EDM) is one of the non-conventional machining processes. Thermoelectric power between the tool and work piece is main factor for on which EDM is based. In EDM process, the material removal rate is important performance measure. Many of the researchers found the no. of ways to improve the MRR. By using Dielectric medium between work piece and tool erosion of electrically conductive work piece is controlled with the rapid and repetitive spark discharge. Work piece and tool both are taken as conductor of electricity, in order to generate the spark. EDM is used for machining of thin and fragile parts. In this paper the micro drilling on conduction material by using EDM is attempted. Based on concentration, current, time and diameter of tool, the MRR is studied.
