A conventional, manually driven Moore No. 3 coordinate measuring machine at the Oak Ridge Y-12 Plant is being upgraded to provide a continuous-path numerical control capability and simultaneously to serve as a vehicle for testing new machine slide control concepts. Besides new lead screw drive motors, an NC machine control unit and closed-loop servo system, the machine has also been equipped with vibration isolation, air-bearing slideways, and laser interferometric position feedback. The present conventional slide servo system will be replaced with a digital servo system wherein various feed back and compensation techniques can be realized through the use of a high-speed dedicated digital processor. This paper describes the improvements to date with emphasis on identification and compensation of the slide control systems.
