In this research two different materials have been machined by sintered copper, brass, and bronze electrodes in electrical discharge machine. The input parameters are varied and output responses have been studied by adopting design of experiments. Response surface methodology has been adopted for analysis of the parameters. Mathematical model has been formulated for all sintered electrodes and to optimise the parameters to obtain maximum material removal rate , minimum tool wear rate and minimum surface roughness. The effects of interaction of parameters has been studied among the three sintered electrodes. Copper electrodes removes high rate of material compared with sintered brass and sintered bronze electrode. Tool wear rate is high for brass electrode.
