  • In the traditional grinding process of zirconia ceramics, there are problems such as large grinding force and poor processing quality. According to the excellent performance of the fractal structure of the veins in drag reduction, diversion and heat and mass transfer, the adaptive growth model and fractal angle model of the veins were established, and the bionic fractal textured diamond grinding wheels with three different fractal angles ( 30 °, 45 °, 60 ° ) were designed. The effects of the original grinding wheel and three bionic fractal grinding wheels on the surface roughness, grinding force and grinding force ratio of zirconia ceramics were compared and analyzed. The experimental results show that compared with the original grinding wheel, the normal grinding force of the bionic fractal grinding wheel is effectively reduced by 12.7 % ~ 55.8 %, and the tangential grinding force is effectively reduced by 8.1 % ~ 40.3 %. When the fractal angle is 30 °, the minimum grinding force ratio is 1.4 ~ 3.0 and the minimum surface roughness value is obtained. This indicates that the bionic fractal grinding wheel has better grinding performance than the original grinding wheel, and provides further evidence for the method of constructing bionic fractal textured grinding wheel based on veins.
