Wire EDM, unlike die sinking EDM machines, has a pure copper wire as the electrode tool. This wire, acting like a cutting tool, moves vertically and advances in the workpiece.... The shape to be obtained is memorized by the machine through the insertion of the work program. Subsequently, the information is transferred to the axes that will guide the wire along the established trajectory in order to obtain the desired shape fully automatically. The wire EDM machine was born and evolved only later after the diffusion of die-sinking EDM. Wire EDM, however, was immediately very successful and is highly appreciated by the market, especially for the machining of precise and complex profiles. As explained in the case of die sinking EDM, the removal process by EDM is due to a combination of thermal and electrical effects. In this process, a conductive material can be eroded if it is struck by a series of electrical discharges, each of which has an imperceptible duration of just a few milliseconds.
