Electric Discharge Machining (EDM) is a non-traditional manufacturing process that uses controlled electrical sparks to erode conductive materials. This article explores the working principles, types (Sinker, Wire, and Hole Drilling EDM), key components, and diverse applications across industries including aerospace, medical, and tool making. EDM offers unique advantages for machining hard materials and complex geometries without mechanical forces, though with limitations like slower material removal rates. The technology continues to evolve with trends toward automation, environmentally friendly systems, and micro-scale applications.
