Abstract

The Precessions™ process polishes complex surfaces from the ground state preserving the ground-in form, and subsequently rectifies measured form errors. Our first paper introduced the technology and focused on the novel tooling. In this paper we describe the unique CNC machine tools and how they operate in polishing and correcting form. Experimental results demonstrate both the ‘2D’ and ‘2½D’ form-correction modes, as applied to aspheres with rotationally-symmetric target-form.
