Over the past two decades, the advancement of metals and alloys with increased difficulty in manufacturing and processing has presented challenges for researchers in the manufacturing sector. This surge in demand is particularly prevalent in technologically advanced industries such as nuclear reactors, automobiles, and aeronautics, necessitating high strength temperature resistant (HSTR) materials with significant strength-to-weight ratios. Materials science scholars are actively engaged in developing materials with enhanced strength, hardness, and durability, which also drives the need for advancements in cutting instrument materials to maintain productivity. Despite recent technological progress, conventional machining methods struggle with processing HSTR alloys, die steels, and complex shapes. Consequently, there is a growing imperative to adopt more recent developments in metal machining, often referred to as unconventional or sophisticated machining processes, where direct energy is utilized instead of conventional tools. Electric Discharge Machining (EDM) is one such process, notable for its ability to achieve precise machining through the use of electrical discharges to erode conductive materials. This paper examines the mechanism, capabilities, advantages, and limitations of EDM, as well as its applications, focusing on the machining of superalloys like Inconel. Additionally, Powder Mixed Electric Discharge Machining (PMEDM) is explored as a hybrid process to enhance machining capabilities and surface quality. The study encompasses experimental investigations on various machining parameters and materials to optimize EDM performance, offering insights for future research in this domain.
