Glass plates were damaged by single‐point and multipoint grinding at various set depths and wheel speeds to evaluate the usefulness of single‐point grinding to simulate the mechanisms of damage penetration and material removal during multipoint grinding. The observed damage was much more severe in single‐point than in multipoint grinding. In both single‐point and multipoint grinding, the vertical load (P v ) dependence of the crack depth (c) P v ∞ c 1.2 . In glass, the effect of the residual stresses in reducing the remaining strengths of the damaged bars was less than that observed for other ceramics previously investigated, mainly because much of the irreversibly deformed zone was removed by crushing. The advantages and disadvantages of using single‐point grinding to simulate multipoint grinding are discussed.
