| Popis: | In the present investigation, the influence of drinking water as dielectric fluid and graphite powder concentration on electric discharge machining of Ti-6Al-4V alloy is studied. Taguchi parameter design approach was used to get an optimal parametric setting of EDM process parameters namely, discharge current, pulse on time, pulse off time and graphite powder concentration that give up optimal process performance characteristics such as material removal rate, surface roughness and recast layer thickness. Also individual effect of process Parameters on performance characteristics was studied. Experiments were conducted on experimental setup with modified dielectric fluid circulating system. To identify the significance of parameters on measured response, the analysis of variance (ANOVA) has been done. Further empirical models were developed by performing nonlinear regression analysis to predict the process performance characteristics. Confirmation tests were conducted at their respective optimum parametric settings to verify the predicted optimal values of performance characteristics. |
