Abstract:
A workpiece micro-positioning apparatus for correcting small pitch and yaw location errors in a workpiece supported on a fixture for manufacturing operations, the apparatus comprising:a biaxial micro-positioner including: a pitch motion mechanism configured to support a workpiece for rotation about a pitch axis; a yaw motion mechanism supporting the pitch motion mechanism for rotation about a yaw axis generally normal to the pitch axis; and a base supporting the pitch and yaw motion mechanism; the apparatus further comprising:a fixture supported on the micro-positioner and configured to releasably hold a workpiece, the micro-positioner configured to allow rotation of the fixture about the pitch and yaw axes to correct any pitch and yaw deviations from a desired workpiece attitude relative to the base and to releasably lock the pitch and yaw motion mechanisms following such correction.
