Patent number: 10336003Abstract: 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.Type: GrantFiled: July 21, 2015Date of Patent: July 2, 2019Assignee: Blue Photon Technology & Workholding Systems LLCInventors: Edward C.
