the cutting tool is programmed to move in 4-nm increments along an x axis and an omega axis. exceptionally stiff and accurate control of the tool is possible with this system. copper surfaces of revolution have been produced with a 12.3-aa rms surface finish and a contour accuracy of 75 nm. in conjunction with a thermally stabilized air bearing spindle and machine calibration equipment, the omega-x system permits a significant advance in the fabrication of optical-quality surfaces for use with the visible spectrum
