Abstract
A method of machining an inner surface of a shroud assembly extending generally circumferentially around a central axis of a gas turbine aircraft engine. The method includes determining pre-machined radial clearances during flight between tips of rotor blades in the engine and the inner surface of the shroud assembly at each of a plurality of circumferentially spaced locations around the shroud assembly. The inner surface of the shroud assembly is machined based on the pre-machined radial clearances to provide a generally uniform post-machined radial clearance during flight between the tips of the rotor blades and the inner surface of the shroud assembly at each of the circumferentially spaced locations around the shroud assembly.
