A machine has been constructed for fabricating concave aspheric surfaces of diameter up to 200 mm and reference radius from 20 mm to 150 mm. The principle is to use a plastic-bonded silicon carbide wheel with a convex cutting surface, which is continually dressed by a diamond form dresser. The cam used for directing the grinding wheel is cut on a numerically controlled jig borer with a tool of the same diameter as the cam follower. In operation, the location of the diamond dresser is used to provide feedback corrections for the grinding wheel.
已制造出一台用于加工直径达200毫米、参考半径为20毫米至150毫米的凹面非球面的机器。其原理是使用具有凸形切削面的塑料粘结碳化硅砂轮，该砂轮由金刚石成型修整器持续修整。用于引导砂轮的凸轮是在数控坐标镗床上用与凸轮从动件直径相同的刀具加工而成的。在操作过程中，金刚石修整器的位置用于为砂轮提供反馈校正。
