ABSTRACT : Electrical discharge machining (EDM) is a nontraditional process that uses electrical spark discharge to machine electrically conducting materials such as tool and dies steels, ceramics, etc., for geometrically complex shapes, which are difficult to machine using a more traditional approach. However due to the process nature there is still failure to accurately understand process parameter influence on the surface quality, material removal rate etc. On the other hand, designing and re-shaping of required electrodes for each feature are time consuming and the number of electrode stored is very high. Therefore to increase the productivity, quality and flexibility standardized simple electrode shapes, capable to machine different features, must be analyzed. This study present the analysis based on Taguchi design and Analysis of Variance (ANOVA) we conduct experiment and find the contribution of Tool Geometry on the Surface Roughness and Material Removal Rate (MRR) with other processing parameters. And find the most significant parameter for both output parameters.
