    摘要: The present application further describes a method for extending the operating life of a tip shrouded turbine blade that includes the steps of: 1) removing an end located cutter tooth from a seal rail of a tip shroud, the end located cutter tooth including a cutter tooth located at the end of one of the suction side and pressure side of the seal rail of the tip shroud; and 2) attaching a center located cutter tooth to the seal rail of the tip shroud, the center located cutter tooth including a cutter tooth that is located in the approximate center of the seal rail of the tip shroud. In such method, the center located cutter tooth may be attached to the seal rail such that the center located cutter tooth is inside the airfoil if it were projected radially outward from the narrowest point below a tip shroud fillet.
