Electrical discharge machining is a manufacturing process with a large industrial implementation. The addition of powder particles in suspension in the dielectric modifies some process variables and creates hard and brittle materials with nano surface finish, high tolerance and accuracy to achieve a material removal rate increase. This paper presents a research work to study the performance improvement of material removal rate (MRR) and tool wear rate (TWR)on the nano particle mixed electrical discharge machining. Work piece used is Inconel 718 and tool materials used brass electrode. The electrolyte used is kerosene oil. Titanium carbide nano particle is having high mechanical and electrical properties specifically high electrical conductivity. The input parameters like current, pulse on-time and pulse off-time and outputs MRR and TWR. The experiment results analysis titanium carbide nano particle mixed dielectric fluid to achieve maximum MRR and minimize TWR.

Keywords: TiC; EDM; MRR; TWR
