[0002] Electrospark machining is a machining method that uses the thermal effect generated by discharge to remove conductive materials. It is mainly used to manufacture workpieces with complex shapes such as molds, cavities, small holes, and special-shaped holes. The basic principle of electrospark machining is to apply a pulse voltage between the tool electrode and the workpiece to generate discharge in the gap between the two. When the discharge occurs, high temperature is generated in the local area, causing the material on the surface of the workpiece to melt and evaporate, thereby achieving material removal. By controlling parameters such as the time, frequency, and energy of the discharge, the amount and shape of material removal can be precisely controlled.
