To solve baffling problem about machining of integral components with special-shaped curved surface, electrochemical contour evolution machining and electrochemical polishing are introduced. It is discussed how to select feed movement means of electrochemical contour evolution machining. Feed parameters designing of the integral impeller blades passageway machining and special-shaped curved surface electrochemical polishing is chiefly studied. An available flowing field designing method is given. The study is very helpful for improving NC (numerical-control) programming, procedure designing and machining tests about the special-shaped curved surface’s machining .By the tests, the integral components up to standard with special-shaped curved surface are produced.
