Abstract

This thesis discusses about the analysis of electrical discharge machine (EDM) die sinking parameters on the material removal rates (MRR) of mild steel. Initially, five important factors are identified as a factor influencing and affecting MRR. The factors are electrical discharge peak current (IP), servo voltage (SV), main supply voltage (V), servo speed (S) and jump speed (JS). Even though five parameters are considered affecting MRR, it is significant to find which are affecting most. So, design of experiment (DOE) method is used to predict the most affecting parameters. After DOE analysis, it is found that only three major parameters plays a vital role in the material removal rate. They are IP, SV and V respectively significant. Based on the significant parameter, a mathematical model is constructed and developed. This design mathematical model is used in the conducted experiment and hence applied to determine the MRR of mild steel.
