Electric Discharge Machining (EDM) is a non-traditional machining process where tricky and multifarious profiles can be machined. Only electrically conductive materials can be machined by this practice and is one of the important machining method for machining high strength temperature resistance alloys. For accomplishing the finest performance of the EDM method, it is critical to convey out parametric design replies such as material removal rate (MRR), surface roughness (SR) etc. It is essential to consider most number of input parameters to get the better result. The objective of this work is to study the influence of three design factors current (I), pulse on time (Ton), pulse off time (Toff) which are the most relevant parameters to be controlled by the EDM process over machining characteristics such as material removal rate, surface roughness. In electrical discharge machining (EDM), a process utilizing the removal manifestation of electrical discharge in dielectric, the working liquefied plays a crucial role affecting the material removal rate and the properties of the machined surface. Choosing the right dielectric fluid is critical for successful operations. This work enhance properties of dielectric fluids by the combination of EDM oil and palm oil. In this work TOPSIS used for optimization.
