Electrodes for electrochemically machining airfoil blades

An electrode pair for electrochemically forming a blade from a workpiece blank having oppositely facing first and second faces defined by a radially inner base, a radially outer top, a first edge, and a second edge, said electrode pair comprising:

• an electrically conductive first electrode having a support portion and a working portion for electrochemically machining said first face of said blank, said working portion having an inlet end and an outlet end;
• an electrically conductive second electrode having a support portion and a working portion for electrochemically machining said second face of said blank, said working portion having an inlet end and an outlet end;
• said first and second electrodes being positionable about said blank for defining an inlet and an outlet between said inlet and outlet ends, respectively, of said working portions of said first and second electrodes;
• means for channeling electrolyte from said inlet to said outlet, portions of said channeling means being fixedly connected to at least one of said first and second electrodes;
• and
• means for sealing said working portions of both said first and second electrodes to substantially prevent leakage of electrolyte from said inlet and outlet, portions of said sealing means being fixedly connected to at least one of said first and second electrodes.
