ABSTRACT:
A control system for precision machine tools and similar devices provides a precise position during active operations on a table supported workpiece or part. The present system provides a support table on which a machine part or specimen is mounted that is controlled in its position through a friction free spring type hinge relative to a base, and which is held therein with a piezoelectric actuator operated in an active closed loop system to maintain a set position without any backlash.
