The adequate selection of machining parameters is of prime importance to take into the account in of advanced engineering materials. The main focus of this experimental study is to observe the effect of electrode material and machining parameters viz. peak current, main voltage and duty factor on EDM of Cobalt-Chromium-Molybdenum (Co-Cr-Mo) using copper and brass electrodes. The findings highlight that electrode material significantly affects the process performance with respect to material removal rate and electrode wear. Better performance and higher efficiency is achieved by copper electrode. Peak current, voltage and duty factor play important roles in EDM performance and efficiency in terms of reducing machining time and improve tool utilization time and life
