In this paper, the effect of silicon powder mixing into the dielectric fluid of EDM on Surface roughness of Al6063 aluminium alloy has been studied. Three process parameters, namely peak current, pulse on time, concentration of powder has been considered. The process performance is measured in terms of surface roughness (SR). The research outcome will identify the important parameters and their effect on SR of Al6063 alloy in the presence of suspended silicon powder in an EDM oil dielectric. The study indicated that all the selected parameters have a significant effect on the mean and variation in SR (S/N ratio). A well-known Taguchi methodology is applied to optimize the SR. The confirmation runs showed that the setting of peak current at a low level (1 A), pulse-on time at a low level (10 μs), powder concentration at a medium level (4 g/l) produced best surface finish from Al6063 alloy surfaces when machined by silicon powder mixed EDM.
