Wire-cut electrical discharge machining, also known as slow wire EDM, is a numerical control machine tool that uses a continuously moving thin metal wire (referred to as electrode wire, typically copper wire) as an electrode to perform pulse spark discharge on the workpiece, generating temperatures above 6000 degrees Celsius and eroding the metal to shape the workpiece. The principle of slow wire EDM is the phenomenon of continuous discharge removing metal due to the existing slit gap between the online electrode and the workpiece.
