Abstract
A method and device for the production of components having a three-dimensionally formed surface by a lowering operation with an electrochemical ablation process, namely a Precise Electro Chemical Machining (PECM) process, is disclosed. The method includes the steps of: a) providing a specially pre-formed workpiece featuring a specific dimensional allowance; b) providing at least one working electrode, in which case the contour of the working electrode, or of each working electrode, is adapted to the contour of the three-dimensionally formed surface to be produced; and c) lowering the three-dimensionally formed surface by placing the pre-formed workpiece and the working electrode, or each working electrode, in an electrolyte and by applying an electrical voltage or an electrical current, in which case the working electrode, or each working electrode, is moved in the sense of a circular advance motion in the direction toward the workpiece.
