Abstract

Current literature is rich with information on the interaction between coolants and metals in metal working. This includes the study of optimum coolant velocities, nozzle positioning, and coolant formations. Very little information exists on the role of coolants in glass grinding. The CNC deterministic microgrinding machines at the Center for Optics Manufacturing utilize water based coolants to provide lubrication at the part/tool interface, to remove heat from the metal bonded diamond tool, and to help keep the tool surface free of debris. We show that the angle of coolant delivery and the coolant velocity do not affect the rms microroughness of a variety of glasses when ground at commercially relevant in-feed rates. We discuss a preliminary experiment utilizing a high pressure coolant delivery system.
