Abstract

The PrecessionsTM process has been developed for the control of texture (�??polishing�??), preservation of form during polishing, and control of form (�??figuring�??), on flat, spherical and aspheric surfaces. In this first and introductory paper, we summarize the need for aspherics, review some aspheric technologies, and then distill a �??wish-list�?? of attributes for an aspheric process. Within this context, we focus on special properties of Precessions tools, their use in a family of 7-axis CNC polishing machines, and present experimental results.
