Abstract

LLNL is collaborating with the Center for Optics Manufacturing and the American Precision Optics Manufacturers Association to optimize bound diamond ring tools for the spherical generation of high quality optical surfaces. An important element of this work is establishing an experimentally-verified link between tooling properties and workpiece quality indicators such as roughness, subsurface damage, and removal rate. In this paper, we report on a standardized methodology for assessing ring tool performance and its preliminary application to a set of commercially available wheels. Our goals are to 1) assist optics manufacturers (users of the ring tools) in evaluating tools and in assessing their applicability for a given operation, and 2) provide performance feedback to wheel manufacturers to help optimize tooling for the optics industry. Our paper includes measurements of wheel performance for three 2-4 micron diamond bronze-bond wheels that were supplied by different manufacturers to nominally-identical specifications. Preliminary data suggests that the difference in performance levels among the wheels were small.
