The principle of EDM (Electrical Discharge Machining) is simple.
The workpiece and tool are placed in the work position so that they do not touch.
A gap remains, filled by the A gap remains, filled by the "dielectric." The workpiece and tool are connected to a direct current power source via a cable.
A switch is inserted in the connection. When closed, an electrical current is set up between the workpiece and tool

In die-sinking EDM, the required shape is formed negatively in the metal with a three-dimensional electrode. By superimposed movements in the main axes x, y, c, z, the most varied shapes, indentations and cavities are created, such as cannot be achieved by any other machining system.

In wire-cutting EDM, the required shape is "computer" stored and passed as comprehensible codes to the machine, which then cuts the shape independently by guiding the wire along the given stretch.
