Abstract
In the electroerosive working or machining of electrically slight or non-conducting workpieces, the workpieces are made electrically conductive, at least in parts of an electroerosion working zone, by means of the supply to the workpieces of electromagnetic energy. As a result, the valency band of the atoms of the workpiece is raised, which produces therein the electrical conductivity.
