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 caster-camber plate assembly has a fastener plate including fastening members. A lower adjustment plate has a first side face positioned adjacent a first side face of the fastener plate such that fastening members of the fastening plate extend therethrough. The lower adjustment plate is moveable with respect to the fastener plate along first and second translation axes. An upper adjustment plate has a first side face thereof positioned adjacent a second side face of the lower adjustment plate with the fastening members extending therethrough. The upper adjustment plate and the lower adjustment plate are jointly configured for allowing the upper adjustment plate to be moveable with respect to the fastener plate along the second translation axis. A plate interlocking structure accommodates relative movement between the adjustment plates along the first translation axis and effectively inhibits relative movement between the adjustment plates along the second translation axis.
