Abstract: A rapid acting adjustable clamp includes a precision ground dovetail track which carries a cam actuated locking assembly along a bridge portion of the clamp to provide quick initial setup, secure workpiece retention, quick release, and highly repeatable subsequent re-actuation of the clamp. The resulting positive acting clamp is particularly advantageous for use in precision grinding, milling, and electron discharge machining operations where a number of similar workpieces are to be machined. The dovetail joint provides rapid sliding adjustment along a first workpiece engaging axis while a single threadedly adjustable screw provides rapid setup along an orthogonal workpiece engaging axis. The combination of these quick adjustments with the single lever cam locking actuation greatly reduces the number of repetitive operator manipulations required in its use, resulting in significantly improved clamping action and in increased productivity by its use.

Abstract: A pinchuck is formed in accordance with this invention by using lithographic techniques to define and to etch a pattern of pins from an extremely flat etchable surface. Since the pins are formed from a surface which is already flat, it is not necessary to level or polish the pins after they are formed. Since lithographic techniques are used, the pin head dimensions, the number of pins, the arrangement of pins, and the density of pins all may be freely chosen without affecting the fabrication cost. By surrounding the region of etched pins with an unetched band, a raised peripheral ring will be formed which can act as a vacuum sealing ring when the pinchuck is used as a vacuum pinchuck. By fabricating the pins from an electrically conductive material (such as doped silicon) and then covering the pins with a dielectric film (such as silicon dioxide), the pinchuck can be used as an electrostatic pinchuck.
