Abstract: A method and system temporarily holds a workpiece, most suitably an aero engine turbine blade element during manufacture. The workholding system includes a support body with a contoured body surface, complementary to a workpiece surface, formed of a transparent material to define a bonding zone. The support body is supported by a base to form a workpiece shuttle, and a bond station receives the workpiece shuttle. Complementary zero-point locating elements on the shuttle and station assure accurate positioning. The bond station further has workpiece locating elements configured to accurately position the workpiece on the shuttle in a predetermined position relative to the zero-point locating elements of the shuttle, thereby compensating for shuttle-to-shuttle variance. An adhesive, such as a UV curable adhesive, is applied to the bonding zone and cured by UV through the transparent material, thereby fixing the workpiece in the predetermined position.

Abstract: A method of allowing a work-piece to obtain its free state shape while bonded to an adhesive fixture includes allowing the fixing surfaces to change shape or position relative to a fixture base without degrading the holding strength of the adhesive joints. A floating adhesive fixture may use one or more floating adhesive fixture devices. Each device includes a fixture element with an integral fixing surface that can displace relative to the fixture, a clamping system that can release or prevent this motion, and a suspension that keeps the fixture element in a nominal position when the clamping system is disengaged. A method includes unclamping the fixture elements and allowing them to displace as the adhesive joints and work-piece reduce strain energy. The clamping of the fixture elements prepares the fixture for the ensuing manufacturing process.
