Abstract:
1. A fixture assembly for retaining a workpiece during a coining process, wherein the workpiece includes an airfoil portion, a platform, and feet extending from the platform opposite the airfoil portion, the feet configured to engage a retention slot in a gas turbine engine, wherein each one of the feet defines a substantially arcuate engagement surface, the assembly comprising: a workpiece that includes an airfoil portion, a platform, and feet extending from the platform opposite the airfoil portion, wherein each one of the feet defines a substantially arcuate engagement surface; a mounting block for releasably engaging the feet, wherein the mounting block comprises: a first portion defining opposite first and second lateral edges; a slot defined in the first portion between the first and second lateral edges and having an exposed front face to provide access to the slot; and first and second retaining structures positioned adjacent to the first and second lateral edges, respectively, of the first portion, wherein each of the first and second retaining structures overhangs the slot and defines an engagement surface facing the slot, such that during engagement of the workpiece the substantially arcuate engagement surfaces of the feet contact the engagement surfaces of the first and second retaining structures to provide a pivotable engagement.
