Abstract

Optical surfaces produced by machining processes place a great burden on the accuracy of the machine tool system. For example, if the motion is produced by linear slide system and actuated by lead screws driven with gears, the machine is limited in figure and surface finish accuracy. A new machine is described, based on only rotary motion, pivoting on air bearing spindles. The new machine, called an Alpha-Theta machine, affords greater accuracy, elimination of lead screw drives, and also minimizes rewelding of chip material to the cut surface. The Alpha-Theta machine is a new generation single point turning machine.
