Abstract

The roughness dynamics of glasses of types BK7 (K8) and TF1 are investigated at the stage of grinding and polishing when they undergo free-lap processing. The relationship is established between the arithmetic-mean roughness and the abrasive graininess at the stage of grinding and the polishing time. It is shown that one can distinguish three stages in the formation of roughness during polishing.
