| Abstract: | In the present study, Response surface methodology was used to investigate the relationships and
parametric interactions between the three controllable variables on the material removal rate
(MRR). Experiments are conducted on AISI D2 tool steel with copper electrode and three process
variables (factors) as discharge current, pulse duration, and pulse off time. To study the proposed
second-order polynomial mode for MRR, we used the central composite experimental design to
estimation the model coefficients of the three factors, which are believed to influence the MRR in
EDM process. The response was modeled using a response surface model based on experimental
results. The significant coefficients were obtained by performing analysis of variance (ANOVA)
at 5% level of significance. It was found that discharge current, pulse duration, and pulse off time
significant effect on the MRR. This methodology is very effectual, needs only 20 experiments to
assess the conditions, and mode... |
