ABSTRACT:
In accordance with a preferred, exemplary embodiment of the invention, an apparatus for forming a blisk from a workpiece is disclosed. The workpiece includes a 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.
The apparatus includes first and second complementary electrodes positionable about the workpiece blank. Each electrode has a support portion and a working portion. Means for channeling electrolyte from an inlet to an outlet defined between the electrodes, and means for sealing the working portions to prevent leakage are disclosed.
Electrolyte is channeled between the first and second edges to finally electrochemically machine an airfoil in a single operation from the blank.
