Optimization of machining parameters of Electric Discharge Machining for 202 stainless steel
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 4
Abstract
: Electric discharge machining is used for machining of hard materials like steel. In this paper, the effect of electrical discharge machining (EDM) parameters such as pulse-on time (TON), pulse-off time (TOFF), and current (I) on material removal rate (MRR) in 202 stainless steel was studied. The experiments are carried out as per design of experiments approach using L27 orthogonal array. The results were analyzed using analysis of variance and response graphs. From this study, it is found that different combinations of EDM process parameters are required to achieve higher MRR and greater surface finish. Signal to noise ratio (S/N) and analysis of variance (ANOVA) is used to analyze the effect of the parameters on MRR and also to identify the optimum cutting parameters. The contribution of each cutting parameter towards the MRR is also identified.
