摘要： An electrochemical grinding tool and method capable of rounding sharp edges that may be prone to cracking, for example, edge regions of cooling slots within dovetail slots of turbine wheels. The electrochemical grinding tool includes a drilling assembly, a conductive bit, and a motor for rotating the conductive bit about an axis thereof. The conductive bit of the electrochemical grinding tool is inserted into a first slot, an electrolyte solution is applied between the conductive bit of the electrochemical grinding tool and a second slot that intersects the first slot, an electrical potential is applied to the conductive bit and the turbine wheel to create a potential gradient between the conductive bit and the edge of the second slot, and material is removed from the edge of the second slot by displacing the conductive bit about and along the edge.

摘要： A system for modifying a slot in a rotor includes a drill, a clamp connected to the drill and configured to engage with an interior surface of the slot, and means for supporting the drill from a stationary platform adjacent to the rotor. A method for modifying a slot in a rotor includes connecting a coupling to a stationary platform adjacent to the rotor, connecting a drill to the coupling, and locating the drill proximate to the slot. The method further includes inserting a clamp into the slot, engaging the clamp with an interior surface of the slot, and operating the drill to create a cavity in the slot.

摘要： A method and a machining kit for machining a bore hole into a shroud block are disclosed. The method includes designating a location of the bore hole on an exterior surface of the shroud block, positioning the shroud block in a machining device, securing the shroud block in the machining device, and machining the bore hole in the shroud block. The machining device includes a locating tool, a machining tool, a platform, a securing device, and a radial support. The radial support is configured to mate with a radial exterior surface of the shroud block such that a machining axis of the machining device may be aligned with a radial axis of the shroud block during positioning.
