A computer‑controlled polisher employs a small rotating tool that scans the workpiece surface. The system controls tool velocity to remove a prescribed amount of material at each point, and it was optimized by adjusting tool configurations, dwell times, scanning paths, and operating parameters. Using a small tool enables rapid figuring of aspheric, lightweighted workpieces, and the unit produced several parts, including a mirror with a 1/80‑wave rms departure (0.6328 µm).
The computer controlled polisher uses a small, rotating tool which travels over the workpiece surface. By accurately controlling the velocity of the tool, a prescribed amount of material may be removed at each point on the surface. The use of a small tool permits rapid figuring of aspheric surfaces for lightweighted workpieces. The computer controlled polisher was optimized with regard to tool configurations, dwell times, scanning paths, and operating parameters. The unit has successfully fabricated several different workpieces including a mirror with a 1/80-wave rms departure, where a wave is 0.6328 microm.
