The High-Energy Gas Laser Fusion Program requires several large optical elements containing aspheric surfaces. A fabrication process utilizing diamond turning for figuring has been chosen as the most feasible when considering cost and allowable. time for fabrication. To diamond turn optics of this size (80-inch diameter), a two-axis horizontal spindle, numerical control turning machine was chosen. Improvements in vibration control, tool path control, and size capability were needed to achieve the desired capability. This paper describes some basic criteria needed for diamond turning. In addition, the major modifications required to achieve these criteria in a machine tool are discussed.
