Abstract
Devices and methods are disclosed for the contactless detection of a bar-shaped or wire-shaped processing electrode of a machine tool such as a spark erosion machine. The detection is based on measuring an impedance change in the measuring area, which is caused by the processing electrode moving through the measuring area. The impedance change is measured by one or more measuring electrodes disposed in the measuring area.
