[0002] Wire cutting, also known as wire cutting, is a processing method that is developed on the basis of electric spark perforation and forming processing. This method uses a moving metal wire as an electrode wire, and generates high temperature through pulsed electric spark discharge between the electrode wire and the workpiece, so that the metal melts or vaporizes, thereby cutting out parts. Wire cutting has the characteristics of high precision, high cutting speed, and high finish, and is suitable for metal processing, mold manufacturing, and electronic manufacturing.
