Study the Effect of Electrode Wear Weight (EWW) in Electrical Discharge Machining (EDM)

Electrical Discharge Machining (EDM) is one of the earliest non-conventional manufacturing processes based on thermo-electr ic energy which removing material from a part by electrical discharges between the tools called electrode and the part being machined in the dielectric fluid called workpiece. One of the most important performance measures in electrical discharge machining (EDM) process are the electrode wear weight(EWW). In the present work an experiments has been done to evaluate the rapidity of wear weight electrode of different material (Copper, Brass and Steel) under the same machining condition to analyze the effect of electrode material and the current on electrode wear weight.
