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.

A method for fabricating a turbine bucket, said method comprising:
- providing a turbine bucket including a tip shroud including at least one seal rail;
- and
- 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
An airfoil bucket for a turbine engine, said bucket comprising:
- a tip shroud extending from said airfoil;
- and
- at least one cutter tooth extending from said tip shroud, said at least one cutter tooth is fabricated from a material configured to wear away during operation of the turbine engine.
