    Abstract: A tool for removing a fastener head from a fastener includes a body that includes an alignment surface configured to couple substantially flush against a structural surface proximate the fastener head. A blade coupled to the body includes a tip configured to sever the fastener head from the fastener as the blade is moved in a first direction generally parallel to the alignment surface from a first blade position to a second blade position. The tool also includes a force transfer member coupled to the body for movement parallel to a longitudinal axis of the force transfer member. The longitudinal axis is oriented at an acute angle with respect to the first direction. The force transfer member is configured to move the blade from the first blade position to the second blade position in response to an impulse received by the force transfer member.

    Abstract: A method for electro-chemical machining (ECM) is provided. Methods may include providing an ECM machine including a controller and a fixture configured for positioning an electrode for ECM, positioning the fixture in a selected dovetail slot of a plurality of dovetail slots in a turbine wheel, the turbine wheel being positioned in-situ in a turbomachine, the fixture positioning the electrode for ECM of a portion of the selected dovetail slot, applying an electrolyte solution between the selected dovetail slot and the electrode, and removing material from the portion of the selected dovetail slot by applying an electric potential to the electrode to create a potential gradient between the electrode and the portion of the selected dovetail slot. The machining may be repeated for each dovetail slot of the turbine wheel in-situ in the turbomachine.

    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.
