ABSTRACT:
Apparatus for precisely positioning a workpiece in a measuring machine having a pair of intersecting reference axes by using first and second physically identifiable workpiece reference points positioned at known locations relative to a workpiece zero line. The apparatus includes a clamp plate (20) on which the workpiece may be mounted, a bearing structure (36,37) for supporting the clamp plate (20) for uniplanar motion and a centering pin and carrier (60) for constraining the clamp plate to pivot about one of the workpiece reference points. A centering spindle (7) supported on the machine may be used to locate accurately the workpiece reference points and thereby to position accurately the workpiece zero line relative to the intersecting reference axes of the measuring machine.
