PROSPECTIVE DOUBLE-SIDED PROCESSING TECHNOLOGY OF HIGH-PRECISION OPTICAL COMPONENTS WITH SPHERICAL SURFACES

Abstract

The paper describes technological machinery schemes for simultaneous double-sided processing of components with high-precision spherical surfaces characterized by different sense of curvature. The paper also presents a developed mathematical modeling of stock allowance removal regularities during spherical surface formation by a free fitting-in method. The methodology of numerical computer-aided investigations has been developed for determination of the most favorable machine settings at the stage of technological process creation for simultaneous double-sided grinding and polishing of lenses. The paper describes a methodology for evaluation of lense stress state that allows to determine optimal plane position of their clamping to the side surface.
