Electrical discharge machining (EDM) is a non-conventional metal removal process as well as one of the best manufacturing processes suitable for producing jigs, fixtures, and dies. Among others, the advance EDM machine is able to cut a workpiece having oblique and taper form. The objective of this paper is to optimize the input parameters of EDM machine, such as discharge current, pulse on-time, pulse off-time, dielectric level and flushing pressure for machining AISI H13 tool steel. The Taguchi design of experiments, the signal-to noise ratio, and analysis of variance are employed to analyze the effects of the input parameters by adopting L27 Taguchi orthogonal array (OA) to conduct experiments. In order to achieve the minimum surface roughness (SR), five controllable factors, i.e., the parameters of each at three levels are applied for determining the optimal combination of factors and levels. The results reveal that the SR is greatly influenced by the discharge current. Experimental results affirm the effectiveness of the method, and also prove that the Taguchi method is suitable to solving the stated problem within minimum number of experiments as compared to that of a full factorial design.
