Zusammenfassung:	According to one aspect, a fixture 600 for an airfoil shroud having a first end edge, a second end edge, a leading edge, a trailing edge, a radially outer side and a radially inner side with respect to a rotor axis of a bucket having the airfoil shroud is provided. The fixture 600 includes a base plate 602, a first member extending from the base plate 602 configured to locate and abut the first end edge, a second member extending from the base plate 602 configured to locate and abut a side of a seal rail, a third member extending from the base plate 602 configured to locate and abut the radially outer side of the airfoil shroud 400 and a template recess formed in the base plate 602 proximate the first end edge to define a geometry of a relief cut in the trailing edge of the airfoil shroud 400.
