a tooling assembly for installation relative to a first and second turbomachine component is provided. The tooling assembly includes an axial mounting portion removably couplable to the first turbomachine component. The axial mounting portion includes a first plate, a second plate spaced apart from the first plate, and at least one turnbuckle assembly that extends between, and is coupled to, the first plate and the second plate. At least one of the first plate and the second plate include a radial compression portion. The radial compression portion includes a compression bar radially movable relative to the axial mounting portion and configured to contact the second turbomachine component.

Mounting apparatuses for turbine airfoils of turbine systems are disclosed. The mounting apparatuses may include a body portion configured to be at least partially positioned between a first airfoil and a second airfoil of the turbine system, and an adjustable, first retention component formed on a first side of the body portion. The adjustable, first retention component may be configured to contact a portion of a suction side of the first airfoil of the turbine system. The mounting apparatuses may also include a second retention component formed on a second side of the body portion, opposite the first side. The second retention component may be configured to contact a portion of a pressure side of the second airfoil of the turbine system.

Mounting apparatuses secured to turbine airfoils of turbine systems

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.

Method for electro-chemical machining turbine wheel in-situ

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.

Fixture for electro-chemical machining electrode

A system for repairing dovetail slots includes a slot adaptor having a body configured and disposed to nest between first and second side walls of a dovetail slot, and a tool holder configured to be coupled with the slot adaptor. The tool holder includes a tool guidance system configured and disposed to direct a tool into contact with one of the first and second side walls of the dovetail slot. A cutting tool is mounted in the tool holder. The cutting tool includes a tapered surface configured and disposed to form a tapered recess in the one of the first and second side walls of the dovetail slot.

Method and system for repairing turbomachine dovetail slots

A milling tool is disclosed. The tool may include a base including a clamp for coupling to a selected mounting slot of a plurality of slots of the rotor; a milling tool including a motorized milling head; and a motorized linear actuator coupling the milling tool to the base. The base mounts the motorized linear actuator at an acute angle relative a portion of the slot to allow the motorized linear actuator to linearly move the milling tool to machine the portion of the slot. The portion of the slot may include, for example, an end face and, more particularly, a root corner of the slot where a cooling slot flange extends from the root of the slot. The milling tool may be portable.
