摘要： An apparatus for forming a blade or blisk from a workpiece by electrochemical machining 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 invention provides for such apparatus a pair of complementary electrodes (18,20) positionable about the workpiece blank. Each electrode has a support portion (140,148) and a working portion (146,150), means (152-164,166-178) channelling electrolyte from an inlet to an outlet defined between the electrodes, and means for sealing the working portions to prevent leakage. Electrolyte is channelled between the first and second edges to finally electrochemically machine a blade in a single operation from the blank.

摘要： In accordance with a preferred, exemplary embodiment of the invention, a method of forming a blisk from a workpiece is disclosed. The workpiece (12) includes a blank (14) 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 method comprises the steps of: positioning first and second electrodes (18,20) adjacent to the first and second faces, respectively, of the blank; supplying (48) a positive voltage to the blank and a negative voltage to the first and second electrodes; channelling an electrolyte (28) between the blank and the first and second electrodes for electrochemically machining the blank; moving the first and second electrodes toward (U,X) the first and second faces of the blank; and moving the workpiece toward (Z) the first and second electrodes. An apparatus is disclosed for practicing the method and the invention can be used for electrochemically machining an airfoil.
