Abstract

A fixture for locating a workpiece in a precisely established position comprises a lower magnetic base and an upper fixture plate, the workpiece being fixtured on the plate. The base includes a permanent magnet which normally clamps the plate to the base but which is disabled and releases the plate when an electromagnet in the base is energized. Prior to clamping the plate to the base, the plate is located in a precise edgewise position on the base by quickly insertable and removable dowel pins adapted to be received by the plate and the base with a precision fit.
