APPARATUS FOR CONTROLLING RELATIVE MOTION BETWEEN GAGE JAWS ON A CONTACTING GAGE

摘要: An apparatus for controlling the relative motion and final position between gage jaws on a contacting type of gage. A driving mechanism is coupled to one provide said jaws. command circuit supplies signals mechanism. Each time commanded move, feed back measures actual jaw produces control signal in response predetermined magnitude motion. The used gate subsequent Consequently, can be brought contact with workpiece held thereon without danger damage workpiece.
