Abstract:
Present work aimed to investigate the surface roughness process parameter optimization during WEDM process for steel. Response Surface Methodology (RSM) is use to investigate the effect of five independent input parameter namely gap voltage (Vg), Pulse on time (Ton), pulse off time (Toff), wire feed (Wf) and flush rate (Fr) over CLA value of surface roughness (Ra).A fractional factorial Design of Experiment of two level were employed to conducted the experiment on EN-31 die steel with chromium coated copper alloy wire electrode. The responses were observed by mathematical modelling using RSM on experimental data. The significance coefficients were observed by performing analysis of variance (ANOVA) at 95% confidence level. Second order RSM modelling technique is the best method to found the significance factor affecting the surface roughness by conducting only very less experimentation. Keywords: WEDM, RSM, SR and ANOVA etc.
