Abstract

The objective of this research is to develop a ring tool polisher for deterministic finishing of optical glass parts on Opticam® machining centers at the Center for Optics Manufacturing (COM). To be successful, the ring tool must reduce rms roughness from 100-200Å to 10-20Å, remove 2-4μm of residual subsurface damage, and preserve the surface figure of the glass part. The medium used to fabricate the polisher must satisfy several criteria. It must contain and be able to release polishing agent to the glass surface in an aqueous environment. It must be capable of being formed or machined into a ring (solid or segmented) with a sharp edge. It must maintain its physical integrity at high tool velocities without exhibiting catastrophic failure under load, and it must not show excessive wear during use. It must not require the assistance of additional polishing slurry. These are formidable requirements.
