Experimental research on the effect of grinding parameters on ceramic machined surface roughness

Abstract

Through the analysis of four factors such as grain size, wheel speed, grinding depth and feed rate and the data obtained from the interaction between factors in orthogonal test, it is proved that grain size, playing a leading part, has the greatest effect on surface roughness. It is also found that the interaction between grain size and wheel speed has more effects than the single factor of wheel speed on the surface roughness, and meanwhile, the interaction between grain size and grinding depth has more effects than the single factor of grinding depth, and the interaction between grain size and workpiece speed has more effects than the single factor of workpiece speed. As a result, every grinding parameter should be determined in accordance with the law of the effect imposed on surface roughness by the interaction between grain size and grinding amount rather than that of single factor.
