A method of reducing the cost of large optical telescopes is the use of a segmented primary mirror. The computer-controlled polisher approach is ideally suited to the fabrication of telescope mirror segments. Since the process achieves controlled material removal by regulating the tool motion, there is no need for any surface symmetry. Recent experiments have demonstrated the ability of this process to figure mirror segments.
