Abstract
A method for fabricating a turbine bucket and an apparatus facilitate reducing tip shroud creep. The method includes providing a turbine bucket that includes a tip shroud including at least one seal rail. The method also includes coupling at least one cutter tooth to the tip shroud, wherein the at least one cutter tooth is fabricated from an abradable material that enables the at least one cutter tooth to be removed from the tip shroud during operation of the turbine engine.
