Abstract: A method for electrochemical machining of a metallic article formed by additive manufacturing includes obtaining or producing the metallic article. The metallic article includes an interior surface and a geometry. The method further includes inserting a flexible, metallic cathode tube into the article. The metallic cathode is spaced apart from the interior surface of the article, and the metallic cathode tube is inserted so as to conform to the geometry of the article. Still further, the method includes introducing an electrolyte fluid into the metallic cathode tube and the interior surface of the article and electrochemical machining the metallic article by applying a voltage across the cathode tube and the metallic article, the metallic article functioning as an anode.
