Abstract

Small grinding and polishing tools are useful for certain applications since they can closely follow the curve of an aspheric surface and are less affected by workpiece distortion than larger tools. Also, the use of a computer to control the action of grinding and polishing tools can increase the efficiency and accuracy of the process. The computer controlled polisher (CCP) takes advantage of both features, moving a tool assembly with small pads over the workpiece under computer control. By varying the amount of time the machine works any region, a controlled amount of material may be removed. Using computer modeling, the best tool configurations are developed to perform any figuring operation. Based upon experimentation, the proper operating parameters for the CCP have been obtained. The machine has been used to fabricate a number of difficult mirrors. As a result of this work, the CCP will be used on important fabrication efforts.
