Abstract

The establishment of Single Point Diamond Machining as a viable production process for metallic, crystalline and plastic optics has resulted in a greater awareness of non-conventional surface geometries from both design and production standpoints. The development by Rank Pneumo Inc. of an Ultra-Precision Aspheric Grinding machine has been prompted by current and predicted market requirements which call for a precision machining process capable of yielding optically smooth aspherical surfaces to a figure accuracy in the order of one wave or less at 632.8nm on workpieces typically no greater than 150mm in diameter.
