The Effects of Material Properties and Process Parameters on Surface Quality During Microgrinding of Glass

Recently, the Center for Optics Manufacturing at the University of Rochester has collected data on the deterministic microgrinding of glasses [Golini and Czajkowski, 1992; abbreviated as GC]. The system used is called OptiCAM and the glasses studied were SF7, F7, K7, BK7, SK7, and KzF6. The process parameters were the tool speed, the infeed rate, and the average diamond particle size. The measured parameters were the subsurface damage and the surface roughness. At the same time, the relevant material properties, the hardness and the fracture toughness, for the same glasses were measured by micro-indentation techniques [Cumbo, 1992].
