ABSTRACT:
A workholder (6) has a contoured bonding surface (7), which essentially matches a contoured surface (4) of an airfoil (1). A plurality of studs (8) are disposed within a plurality of tapped holes (9) located about the workholder bonding surface. In operation, the studs are extended outwardly from the surface, and both the studs and bonding surface are contacted with a release agent (10). A curable resinous material (11) is applied to the bonding surface and studs, and an airfoil positioned next to the bonding surface, sandwiching the resinous material therebetween. After curing, a plurality of tapped holes (13) are formed in resin layer (11), with the extended studs fixably positioning the airfoil relative to the workholder. Removing the studs provides heatless release of the airfoil from the workholder.
