Abstract

Disclosed is a method for the electrochemical machining of a workpiece, in which at least one electrode is situated adjacent to a surface to be machined and current pulses are generated in pulsed operation to ablate material from the workpiece. Before and/or at the beginning and/or during the electrochemical ablation, data of the current pulses are registered and analyzed to identify a starting phase or a transient phase comparable to a starting phase and/or to regulate the spacing of the electrode to the surface to be machined and/or the current flow during a starting phase or a transient phase comparable to a starting phase.
