Abstract

Eng. Mona A. Younis

Electrical Discharge Machining (EDM) is used in cutting special steel accurately; in this paper the effect of electrode material will be studied to avoid the surface cracks. Two grades of tool steels are chosen as test materials, DIN 1.2080 and DIN 1.2379 they are a high carbon, high chromium alloy tool steels with excellent resistance to wear and abrasion four types of EDM electrode material has been chosen, Dura graph 11, Dura graph 15, Poco graphite “EDM-C 3”, and copper electrodes.
