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.

Identifying and regulating the starting behavior during electrochemical machining of workpieces

A method for removing a layer made of a first material from a surface of a body made of a second material is disclosed. The body is subjected to a pressurized jet containing a blasting medium composed of particles, where the pressurized jet at least intermittently has an Almen intensity of at most 0.35 Almen A, preferably at most 0.3 Almen A and particularly preferably at most 0.25 Almen A.
