Abstract
A bucket tip shroud in a gas turbine includes a seal rail having a cutter tooth at one end. Bucket tip shroud creep rate can be reduced by removing the cutter tooth from the bucket tip shroud seal rail after use or with a pre-groove honeycomb shroud. Preferably, the remaining geometry matches a geometry of the seal rail within a predetermined tolerance.
