Paper Abstract

For precise deterministic microgrinding of optical components, the exact location of the region of contact between the machine tool and the glass work piece needs to be specified. Any tool compliance therefore contributes to a lack of precision during grinding and to error in the final surface of the glass work piece. The goals of this work are to analyze the dependence of ring tool compliance changes and to develop simple analytical formulas that express these relationships for machine tools used in spherical lens fabrication. Numerical predictions have also been obtained using NASTRAN, a linear finite element analysis routine. The numerical results have been compared with estimations obtained from approximate analytical expressions to determine the ranges of validity of the expressions. These simplified expressions can be used to aid the design of ring tools for smaller [O(mm) diameter] and larger [O(m) diameter] optical lens fabrication.
