“…In a later study, brass was also reported to have the worst wear ratio during micro-EDM drilling of brass, magnesium, AISI 304 and titanium [46]. Surekha et al [100] applied brass electrodes in the machining of high carbon high chromium steel and developed regression models to predict performance measures. In the field of ceramics, EDM brass electrodes were used to EDM ZrO 2 using the electrode assistance method and compared to copper and graphite [55].…”

Over the years, sinking electrical discharge machining has become one of the most important production technologies to manufacture very accurate three-dimensional complex components on any electrically conductive material. This article reports a literature review on the diversity of conventional and non-conventional materials that are used or have potential to be used as EDM electrodes. In addition, additive manufacturing of EDM electrodes are also reviewed.
