abstract = "The mechanism of subsurface crack formation and extension in grinding optical glass by single abrasive based on the dynamic impact effects is studied. Experiments show that the single abrasive grinding cracks of optical glass is dynamic impact crack. Analyzing according to crack system, it can be generated that the impact stress in single abrasive regional is cylindrical stress. The mathematical model of single abrasive area impact stress wave is established, and the influence law of the single abrasive grinding impact area on the sub-surface crack depth is derived. According to the experimental results, the single abrasive grinding cracks is a kind of impact crack, and cylindrical stress wave mathematical model is consistent with the experiment, and the sub-surface crack depth increases in pace with the increase of chord length of impact arc. The dynamic impact crack of optical glass in extending downward has its own self-limiting, and occur lateral bending to some extent.",
