What process does Wire EDM utilize to achieve cuts?

Wire EDM (Electrical Discharge Machining) utilizes high voltage wire to achieve precise cuts in material. In this process, a thin wire, often made of brass or copper, is fed through the workpiece and is energized with a high voltage. This creates an electrical discharge between the wire and the workpiece, which results in localized melting and vaporization of the material. This enables the wire to slice through hard metals and other materials with high accuracy and minimal mechanical stress on the workpiece.

Wire EDM stands out for its ability to produce intricate shapes and contours that are challenging to achieve with traditional machining methods. It is widely used in tool and die making, as well as in the production of complex parts across various industries. The other options do not describe the Wire EDM process accurately, as they pertain to different machining techniques or energies that do not involve the specific mechanism of high voltage wire discharge.
