摘要

A system (40) for modifying a slot (24) in a rotor (18) includes a base (44) having a vertical axis (46). a drill (42) is slidingly connected to the base (44) along the vertical axis (46), and a clamp (80) is connected to the base (44) and configured to engage with an interior surface of the slot (24). a method for modifying a slot (24) in a rotor (18) includes locating a drill (42) proximate to the slot (24) and inserting a clamp (80) into the slot (24), wherein the clamp (80) is slidingly connected to the drill (42). the method further includes engaging the clamp (80) with an interior surface of the slot (24) and operating the drill (42) to create a cavity (28) in the slot (24).
