Abstract: The present application provides a tool for cleaning a groove of a turbine rotor disk. The tool may include a pair of guides spaced apart from one another in a direction of a longitudinal axis of the tool, and a number of cleaning sheets positioned between the guides in the direction of the longitudinal axis of the tool. At least a portion of each guide may have a cross-sectional profile corresponding to a cross-sectional profile of the groove, and at least a portion of each cleaning sheet may have a cross-sectional profile corresponding to the cross-sectional profile of the groove. The present application further provides a method for cleaning a groove of a turbine rotor disk, and a tool system for cleaning a groove of a turbine rotor disk.

Abstract: A milling device for machining a slot into an inner surface of a casing for a gas turbine engine. The milling device includes a frame assembly including multiple structural guides configured to engage structural features on the inner surface of the casing to maintain an axial position of the milling device relative to a longitudinal axis of the casing. The milling device also includes a milling cutter coupled to the frame assembly. The milling device is configured to be displaced in a circumferential direction relative to the longitudinal axis to machine the slot, via the milling cutter, along the inner surface of the casing in the circumferential direction.
