Abstract:

This paper conducted a series researches of micro-grinding for hard brittle material soda-lime glass and discussed the influence of different grinding factors on the workpiece surface quality. The micro-grinding machining mechanism was discussed theoretically, the influences of the undeformed chip thickness and the elastic recovery in the micro grinding process were studied. According to the characteristics of micro-grinding, orthogonal test and single factor test were designed on the soda-lime glass with different machining parameters and got the general developmental law of the surface roughness of workpiece in micro-grinding. With 200# and 500# micro-grinding tools, the experiments were conducted to draw the relationship among different processing conditions and the surface roughness of workpiece, and then determine the influence of the processing parameters on the quality, providing significant results for the quality of micro-grinding and intense research for the development of micro-grinding.

Key words: micro-grinding, soda-lime glass, micro-grinding mechanism, surface roughness
