Abstract
AbstractCurrent study reports the experimental analysis of SS 304 and the effect of process parameters (such as pulse-on time, pulse-off time, arc on time, arc off time, wire feed and servo voltage) on the responses (such as material removal rate and surface roughness) in Wire EDM. L27 orthogonal array offers to minimize the experimental run number and to analyze the effects of significant process parameters on the performance characteristics, the RSM (Response Surface Methodology) technique is called for. ANOVA (Analysis of Variance) analysis is carried out to resolve the outcome of process parameters and to establish a correlation among the parameters. To evaluate the responses, the second-order quadratic mathematical model has been developed. The analysis exposes that servo voltage and pulse on time (higher terms) are the most important among the process parameters for finding the MRR (Material Removal Rate) and KW (Kerf Width), respectively.
