- Abstract
In order to better control the grinding temperature and workpiece quality, in this work, the bionic phyllotaxis was applied into the internal cooling cup wheel. According to the principle of bionics, the arrangement of sunflower seed was set as research object; then, the parameters of the phyllotaxis arrangement were analyzed; here, the arrangement of sunflower seed was called phyllotaxis arrangement. After that, the computational fluid dynamics (CFD) method was used to explore flow characteristics of the cup wheel with different structured surface, and the influence of phyllotaxis growth coefficient on coolant supply of internal cooling cup wheel was analyzed. Then, the corresponding structured abrasive grain ring was prepared by electroplating method, and the grinding experiment of internal cooling cup wheel was carried out. According to the experimental results, by application of bionic phyllotaxis in internal cooling cup wheel, the grinding temperature decreased by 32.8% at most, the surface roughness decreased by 39.9% at most, and the surface microhardness decreased by 9.6% at most. The above results indicate that the application of bionic phyllotaxis can significantly enhance grinding performance of the cup wheel, and the phyllotaxis parameters had obvious influence on the temperature of grinding and the surface quality of workpiece.
