A method for forming an arcuate electrode adapted for the electrolytic production of grooves in the arcuate surface of an article, in which grooves are first formed in a plane metal blank. The grooved blank is then reshaped to have a curvature corresponding to that of the article, and the grooved curved surface of the blank is coated with an insulating material. The insulating material is then removed from the surface of the blank, except in those areas overlying the grooves, and the thus bared portion of the blank is then eroded, for example, by etching, so that the residual insulating layer projects from the surface of the blank. In use, the thus formed electrode is employed as a cathode, with the projecting insulation being held in close contact with a corresponding curved surface of the article to be grooved. The article is connected as an anode, and an electrolytic liquid is directed to flow in the channels formed between the electrode and the article. |
