Paper Abstract

Conventionally, aspherical surfaces of revolution are produced by numerically controlled machines of the XYZ axis configuration or by correction of best fitting spherical surfaces using lapping and polishing techniques. Described here is a machine and means for converting this machine to achieve best fitting toroidal surfaces to a desired aspherical surface. The common chordal generator is a simple machine used to produce spherical surfaces. By revision, it may be made to produce aspherical surfaces of revolution.
