Study of Tool Electrode Wear in EDM Process

Abstract:

Technology of Electrical Discharge Machining (EDM) uses thermal energy in material removal, in which is the electrical energy transformed, generated between the electrodes (tool and workpiece). The material removal occurs through the rapid periodic repetitive electrical discharges in the presence of dielectric fluid. By the action of electrical discharges occurs to decline not only particles of a metal workpiece material, but also to decline in a certain proportion of metal particles in tool electrode. The paper deals with the diagnosis the size of the electrode wear of tools made from copper and graphite used in EDM machining.
