Shear-Mode Grinding Based on The Constant Grinding Force.

Journal of the Japan Society for Precision Engineering, 1997
In the shear-mode grinding of brittle materials, the performance of grinding wheels is often described as the grinding force, which usually changes during the process. However, it was ascertained that a steady constant grinding force exists under shear-mode grinding of optical glass of BK7.
