Abstract

An electrode and method for the electrochemical machining of a workpiece is disclosed. The electrode is designed as a cathodically polarized tool electrode. It has a geometry that corresponds to the geometry to be removed from the workpiece, at least in a machining range, and perviousnesses in the electrode to allow an electrolyte to flow through and exit at the electrode surface, at least in the area of the machining range. The perviousnesses are formed by a porous design of the electrode and/or by artificially created openings in the electrode or the electrode surface. The porosity distribution and/or the number, arrangement and configuration of the openings is selected such that a uniform electrolyte flow and/or electrolyte exchange at the electrode surface is ensured at least in the machining range of the electrode.
