Electrical discharge machining process is a popular non-traditional machining process widely used to machine any conducting material irrespective of hardness and strength. In the present work, remarkable improvement of machining performances like material removal rate (MRR), Tool Wear Rate (TWR) and Surface Roughness (SR) have been observed using SiC powder mixed in the usual EDM oil while machining Ti-6Al-4V material. It is also observed that there is decrease of crack density of the machined surface due to addition of SiC powder in EDM oil. At last, optimum sets of process parameters have been reported using MRSN technique in both powder mixed case and without powder mixed case.
