Abstract: A gas turbine component blank is shaped by clamping the gas turbine component blank into a fixture that accurately positions the gas turbine component blank in three dimensions. The positioning is accomplished against stops accurately machined into a base of the fixture, by first supporting the gas turbine component blank on one set of stops that prevents movement in the direction perpendicular to a plane of the base, and then operating a movable clamp to force the gas turbine component blank against other sets of stops that limit the movement of the gas turbine component blank in directions lying in the base plane. The clamp has a compound movement that simultaneously forces the gas turbine component blank against stops that prevent movement in orthogonal directions lying in the base plane.

Abstract: A non-contact holder including one or more chucks holds a planar workpiece such as a semiconductor wafer, particularly a thin wafer. Each chuck in the holder includes a cavity that opens to a surface adjacent to the workpiece. A tangential orifice introduces a tangential gas flow into the cavity to create a vortex having a central, low-pressure region. A central orifice directs a gas flow into the low-pressure region of the vortex. The combination of gas flows creates a more uniform vacuum attraction holding a workpiece in close proximity to the chuck. The gas exiting from the chuck provides a cushion that prevents contact between wafer and chuck. Small diameter chucks located close to each other help avoid distortion when processing very thin workpieces. In addition to equalizing pressure, the central gas flow increases the angular spread of gas exiting from each chuck and thus simplifies the design of a holder providing a gas flow that inhibits entry of contaminants between the holder and the workpiece.

Abstract: The devices and systems encompass the provision of a plurality of supports specially designed to closely support a work piece immediately adjacent the edge being worked, ground or polished. The top surfaces of the supports are machineable in place on the working table to insure that all are brought to exactly the same height to prevent adjacent supports from creating uneven support and adjacent shear forces. The top members of the supports are a hardened plastic which will not enable the work piece to displace downwardly but which will provide a vacuum downward force. The hardened plastic top of the edge hold down are machineable without losing the ability to act as a vacuum hold down. The shape of the hardened plastic top portions of the edge hold downs are complementary to each other and provide gently interlocking support and can be placed closely enough to eliminate the possibility of any significant amount of work piece area exposure which could produce shear forces.
