Abstract
The electrical discharge machining (EDM) process is one of those nonconventional processes that is used frequently for cutting brittle, hard materials and for making difficult shapes. It is used to manufacture metal matrix compounds and very solid materials. This research focused on studying the effect of three different materials type of electrodes tool. The performance of electrodes produced from copper (Cu), graphite (Gr), and composite materials (Cu-Gr) specified is compared in assessing the roughness (Ra) of the workpiece and the electrode's wear (EW). These electrodes were used in a process to machine titanium alloy, aluminum alloy, and stainless steel 304 samples. Through the experiments and based on the data obtained, it has been proven that electrodes made of (Cu-Gr), some experiments, showed high performance and wear resistance (WR) than others, and to increase the electrical discharge machining processing efficiency of aluminum alloy and SS304, as well as for the processing of titanium alloy, concluded that it was suitable to use a tool produced of composite materials.
