Abstract

A combination of a workpiece support means and a workstation allow a workpiece to be positioned for machining. The support includes a precision way and a transfer fixture slidable along the way. The transfer fixture has precision ground datum markers for locating a workpiece in the vertical sense, and supports means providing an upright surface against which the workpiece can be urged, thus establishing for the workpiece a limit position in one horizontal direction. Locator devices are provided to clamp the workpiece into a predetermined position in the horizontal direction at right angles to the direction established by the upright surface, and a transfer bar or the like moves the transfer fixture. At the workstation there is provided a clamping device for urging the workpiece downwardly against the datum markers, a further clamping device for urging the workpiece firmly against the upright surface, and a third clamping device for clamping the transfer fixture against the precision way.
