EDM can also be used to produce finished parts, such as special shaped cutting tools, parts cut from solid pieces of metal and other items of complex shapes. EDM works by using electricity rather than cutting. The electric spark actually vaporizes the metal. The sparks, produced by a spark generator at regular intervals, create a succession of craters in the workpiece. In EDM, an electrical discharge is created between the surface of the object and the finishing tool that induces temperatures of between 10,000 and 20,000 degrees centigrade. The size of the crater depends on the energy turned out by the spark generator. The range of the sparks varies from a few microns to 1mm.Design a product (job piece) using the Electrical Discharge Machining (EDM) wire cut through NC programming.
