Abstract

The wear particle impact action on specimen is directly related to the shape and depth of sub-surface crack in the grinding process of optical glasses. Thus, the research on the optical glasses grinding wear particle dynamic impact effect is an important fundamental task to the field of optical manufacture. According to the influence law of the optical glasses grinding wear particle impact effect on the shape of sub-surface crack, this paper studies on optical glasses single-grit low speed scribing and linear impact. There are long cracks extending to both sides in the sub-surface crack which is formed in low speed scribing. The gap contour of low speed scribing specimen is indistinct. There are circumferential cracks in the sub-surface crack which is formed in linear impact. The gap contour of linear impact specimen is distinct. This paper studies on the sub-surface crack shape of single-grit low speed scribing and linear impact optical glasses specimen and specimen gap contour. The results showed that the single-grit wear particle dynamic impact effect on optical glasses specimen has important influence on sub-surface crack shape. The optical glasses grinding sub-surface crack is dynamic impact crack.
