Electrical discharge machining characteristics of inconel 718 alloy using titanium carbide (TiC) nanoparticles mixed dielectric fluid was studied. Experiments have been performed according to face centered central composite design. The effect of input parameters such as current, pulse on-time and pulse off-time on the output responses like material removal rate (MRR), tool wear rate (TWR) and surface roughness (Ra) are evaluated. Dielectric fluid used in this experiment was kerosene mixed with TiC nanoparticles. The result shows that MRR and Ra gets improved, TWR get reduced.
