摘要
An innovative engineered grinding wheel with an abrasive phyllotactic grain pattern was presented in this paper. In order to analyze ground surface roughness contrastively, the surface roughness model in grinding using the grinding wheel with the abrasive phyllotactic pattern and the wheel with a general grain structure pattern was established. The grinding processes using the two kinds of engineered grinding wheel have been simulated in different conditions including three kinds of workpiece speed and three kinds of grinding depth. The results showed that the roughness of the ground surface using the grinding wheel with the abrasive phyllotactic pattern was better, which had been validated by corresponding experiments. The relationship between the phyllotactic coefficient and ground surface roughness has also been simulated and compared with experimental results. With the help of the simulations, the influence rule of the phyllotactic coefficient was analyzed finally.
