Abstract
A fixture for an electro-chemical machining (ECM) electrode is provided. The fixture may include a clamp having a shape and size configured to selectively engage in at least a portion of a selected dovetail slot of a plurality of dovetail slots in a turbine wheel. An electrode mount positions an electrode head relative to the clamp such that the electrode head operatively engages a portion of the selected dovetail slot for electro-chemical machining of the portion. The fixture's electrode may act as a cathode for the ECM process. The fixture allows for ECM on site without removing a turbine wheel from a turbomachine.
