 This paper examines the use of electric discharge machining, EDM, to create T6L4V surfaces with different degrees of roughness. For different electrodes were tested graphite, copper, brass, and aluminum against two experimental phases. The results showed that the aluminum electrode produced the lowest roughness while the graphite electrode produced the highest roughness. Additionally, increasing the pulse on time or current resulted in higher roughness values. This article was authored by Mohamed Umar Farouk, Saqib Anwar, Haider Ali Bhatti, and others.
