Abstract: A system for supporting workpieces during machining. The system comprises one or more adjustable workpiece support assemblies and a robotic unit. Each workpiece support assembly comprises a pedestal and a rotatable fixture element. The robotic assembly comprises means of mobilizing and immobilizing each support assembly, so that the fixture element may be secured in a particular orientation. The robotic unit moves along a frame, and manipulates and fixes the position of the fixture elements to match the contour of a workpiece. Vacuum forces may be applied through the workpiece support assemblies to secure the workpiece against the fixture elements.

Abstract: A machining system for controlling and moving work tools during machining and assembly operations. The system has multiple drive-guide systems that allow work tools to be moved along all three perpendicular Cartesian axes. The drive-guide systems have rollers that are designed to fit and move along rails, thus altering the position of the work tools. A plurality of magnets apply axial pre-load to the rollers, keeping them adequately positioned on the rails. Likewise, a preloaded roller may be used to modify the radial force applied to the drive rollers. Both this radial and axial preload can be adjusted to reduce calibration and tolerance errors throughout machining and assembly processes.

Abstract: A generally inverted “T” shaped, resiliently self locking, integral sportboard fastener is adapted to be received in a countersunk aperture formed in a sportboard such as a snowboard, ski, boogie board, skateboard or any other board which supports a person and has one or more structures attached thereto. The fastener comprises a noncircular base portion to be received within a countersink defined in the sportboard. The base and the countersink comprise two parallel sides and two opposite concentric arcs forming two opposite ends. A generally cylindrical integral ferrule portion extends upwardly from the base, through a bore defined in the sportboard, concentric with the countersink. The ferrule defines internal threads to receive a screw to secure a binding or other fixture to the sportboard. An internal annulus portion is defined at the juncture of the base and ferrule. A generally circular, preferably nylon, resilient insert ring is disposed within the annulus.
