In order to solve the problem that the surface roughness of engineering ceramics is difficult to control, this paper studied the influencing factors of surface roughness of zirconia ceramic grinding. The effects of grinding depth, grinding wheel speed and workpiece feed rate on surface roughness were analyzed by the orthogonal experiments of zirconia ceramic grinding. On this basis, single factor experiments were carried out respectively, and the optimal combination of process parameters was analyzed. In addition, an empirical formula of surface roughness for the grinding of zirconia ceramics was established based on the experimental results. The results showed that the grinding depth had a great influence on the surface roughness, the grinding wheel speed effect was secondary, and the effect of the workpiece feed rate on the surface roughness was not very obvious. Compared with the measured value, the maximum relative error of the predicted value was less than 5%, which indicated that the empirical formula had a better prediction effect and provided a theoretical basis for reasonable selection of grinding parameters in actual processing.
