A fixture for holding a workpiece during a manufacturing process includes a base and a rod received by and moveable relative to the base. The rod includes a proximal end presenting a bonding surface. Adhesive establishes an adhesive bond extending between and bonding to the bonding surface and the workpiece. The bonding surface is moveable with the rod relative to the base in an adhesive bond destroying motion. A method of holding the workpiece on the fixture includes the step of adjoining the adhesive to the bonding surface and to the workpiece to create the adhesive bond between the bonding surface and the workpiece during the manufacturing process. The method also includes the step of displacing the bonding surface relative to the base and relative to the workpiece to destroy the adhesive bond between the bonding surface and the workpiece after the manufacturing process has been performed on the workpiece.

What is claimed is: 1. A method of holding a workpiece on a fixture including a base and a rod presenting a bonding surface and being received by and moveable relative to the base; said method comprising the steps of: adjoining adhesive to the bonding surface; adhering the adhesive to the bonding surface and to the workpiece to create an adhesive bond between the bonding surface and the workpiece to hold the workpiece during a manufacturing process; and displacing the bonding surface relative to the base and relative to the workpiece with at least one of a rotational movement and a vibrational movement to destroy the adhesive bond between the bonding surface and the workpiece. 2. The method as set forth in claim 1 wherein the rod extends along an axis and wherein the step of displacing the bonding surface is further defined as rotating the rod about the axis of the rod. 3. The method as set forth in claim 2 wherein the rod includes a head opposite the bonding surface on the rod and wherein the step of displacing the rod with the rotational movement is further defined as exerting rotational force on the head. 4. The method as set forth in claim 1 wherein the rod extends along an axis and wherein the step of displacing the bonding surface further includes linearly translating the rod in the bore along the axis of the rod. 5. The method as set forth in claim 4 wherein the fixture includes a lever coupled to the rod and pivotal about a pivot point spaced from the rod and wherein the step of linearly translating the rod is further defined as exerting a force on the lever. 6. The method as set forth in claim 1 wherein the rod extends along an axis and wherein the step of displacing the bonding surface is further defined as rotating the rod about the axis of the rod and translating the rod along the axis of the rod. 7. The method as set forth in claim 6 wherein the base defines a bore and threads in the bore and the rod is threaded and disposed in the bore and wherein the step of displacing the bonding surface is further defined as rotating the rod relative to the threads in the bore of the base. 8. The method as set forth in claim 1 wherein the step of adhering the adhesive is further defined as positioning the workpiece in contact with the adhesive. 9. The method as set forth in claim 1 wherein the step of adhering the adhesive is further defined as curing the adhesive. 10. The method as set forth in claim 9 wherein the adhesive is further defined as light activated adhesive and the step of curing the adhesive is further defined as exposing the adhesive to radiant energy. 11. The method as set forth in claim 10 wherein the rod includes core presenting the bonding surface and being capable of transmitting radiant energy and the step of exposing the adhesive to radiant energy is further defined as transmitting ultraviolet light through the core to the adhesive. 12. The method as set forth in claim 1 further including the step of maintaining the workpiece stationary relative to the base such that the adhesive bond is destroyed when the bonding surface is displaced relative to the base and the workpiece. 13. The method as set forth in claim 12 wherein the fixture includes at least one locator pin and the step of maintaining the workpiece stationary is further defined as blocking the workpiece against the at least one locator pin. 14. A fixture for holding a workpiece during a manufacturing process, said fixture comprising: a base; and a rod received by and configured to be moveable relative to said base with at least one of a rotational and a vibrational movement and including a proximal end presenting a bonding surface for receiving an adhesive such that the adhesive establishes an adhesive bond extending between and bonding to said bonding surface and the workpiece; said bonding surface being moveable with said rod relative to said base with at least one of said rotational movement and said vibrational movement for displacing said bonding surface relative to the workpiece to destroy the adhesive bond between said bonding surface and the workpiece. 15.
