摘要

The geometry of the intermediate space between both electrodes is measured so that only the points of the zones to be processed lie within the maximum distance dmax. Process for electrochemically processing a workpiece comprises using a voltage that has a value lying within the region of the system characteristics, in which no noticeable reaction stream flows. The deviations of the amplitude of the voltage relative to the average value are dimensioned so that the electrochemical double layer is periodically shifted between two charging voltages on the workpiece or only in regions lying not further than a selected maximum distance dmax from the tool electrode. The geometry of the intermediate space between both electrodes is measured so that only the points of the zones to be processed lie within the maximum distance dmax.
