Abstract

Abstract: Electrical discharge machining behavior of nickel based super alloy using titanium carbide powder mixed dielectric fluid turned into studied. Experiments were completed consistent with face centered central composite design. 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. The effect of input parameters such as current, pulse on-time and flushing pressure on the output responses like material removal rate and tool wear rate are evaluated. Dielectric fluid used in this experiment was kerosene mixed with titanium carbide powder.
