Abstract Accurate prediction of electrode shapes is most important in electrochemical manufacturing process which includes electrochemical machining and electroforming. In the former process, the electrode design is focused on the prediction of the cathode tool which significantly affects the machining accuracy. In the electroforming process, the anode electrode shape determines the current density distribution and so the properties of the deposited metal. This paper proposes a finite element approach to accurately determine these electrode profiles. The proposed method does not require Iterative redesign process, therefore provides excellent convergence and efficient computing. Close agreements between theoretical and experimental results have been observed.
