Abstract

This paper is an updating and continuation of an earlier paper, Annular Lapping of Precision Optical Flatware. Restricted to precision lapping and to machines that can move parts in pure translation across a viscoelastic medium, it will discuss: the availability, cost, and cost effectiveness of the process; the pure translation principle; and behavior of the viscoelastic medium; current thinking on control; the new generation or large laps in planning; and near flat spherical lapping. It is geared to extending the technology with particular emphasis on large parts.
