Abstract
In this study, Sparking parameters specifically Current (I), pulse on time (ton), pulse off time (toff), spark gap and dielectric flushing pressure (P) are optimized with the consideration of multi responses such as Material Removal Rate (MRR) and Electrode wear Rate (EWR). The characteristic features of the Spark EDM process are explored through Taguchi L18 orthogonal array design of experimental studies with various process parametric combinations. To optimize the above machining parameter, grey relation techniques are used. Based on the grey relation grade, optimum levels of parameters have been identified and major contribution of parameters is determined by ANOVA. Verification test is conducted to validate the test result.
