Abstract

Electro Discharge Machining (EDM) is one of the most effective nonconventional machining processes in order to obtain better finishing quality result. It is vastly used to machine the most complex as well as intricate shapes so as the productivity increases in a very short time interval. The input parameters are; discharge current, voltage and pulse on time. Taguchi L9 orthogonal array is used to find out the Signal to Noise ratio by optimizing the performance parameters based upon the input parameters. The performance parameters so optimize as material removal rate, tool wear rate. Using the GREY RELATIONAL ANALYSIS, the correlation has to be draw out that makes the optimized value very accurate
