Comparison of Materials for Use in the Precision Grinding

The ductile grinding of optical materials is a rapidly evolving process. Ductile regime grinding is the technology of grinding brittle materials at material removal rates and depth of cuts that allow for predominantly ductile removal of material as opposed to brittle fracture of the material. It has been hypothesized that for any material, if the material removal rate is sufficiently small
