Abstract
In a method for setting the distance between an electrode and a workpiece in electrochemical metal working, the electrode is moved by an oscillating drive system, in which an acceleration signal of the oscillating drive system is picked up, the acceleration signal is divided into individual sections, characteristic magnitudes of the individual sections of the acceleration signal are determined, the characteristic magnitudes of the individual sections are compared to one another and the distance of the electrode from the workpiece is adjusted in response to a deviation of the characteristic magnitudes from the specified values. A device for carrying out the method includes an electrode, that is connected to a drive axis, an oscillating motion being able to be transferred to the electrode via the drive axis. A sensor is situated on the drive axis which picks up acceleration signals.
