Wire Electrical Discharge Machining
Wire electrical discharge machining (EDM) is a process of metal machining in which a tool discharges thousands of sparks to a metal workpiece. A non-conventional process, though hardly a new one, wire electrical discharge machining (EDM) works on parts resistant to conventional machining processes, but only if these parts are electrically conductive; usually, they are non-ferrous, and include steel, titanium, super alloys, brass, and many other metals. Instead of cutting the material, wire electrical discharge machining (EDM) melts or vaporizes it, producing comparatively small chips and providing a very accurate cut line. Industry-wide acceptance has led to a wide variety of wire electrical discharge machining (EDM) applications, as it is highly versatile, can cut hard metals, and utilizes a relatively compact amount of workspace.
