In this thesis, an enhancement of thermal properties of dielectric has been performed by adding copper nanoparticle into it. For this purpose the nano-particles were manufactured and whole process is demonstrated experimentally. It was found that up-to some extend conductivity of the base fluid increasing with the concentration of nanoparticle addition. Moreover, the practical application of the present concept has been experimentally analyzed by conducting the experiments on Electrical discharge machining (EDM). This work primarily focuses on enhancement of thermal conductivity of dielectric fluid used in Electric Discharge Machining. Experiments were conducted on electric discharge machine to investigate the influence of copper nano particles on the material removal rate, surface roughness and enhancement of thermal conductivity of the dielectric fluid used in Electric Discharge Machining. Here, PMEDM, a new EDM technique is used where a powder is added in the dielectric fluid. PMEDM has shown good results as compared with conventional EDM. It has been observed that material removal rate increases with the increases in discharge current. The results were obtained 18 to 36 % increment in the metal removal rate due to enhancement of thermal conductivity.
