Abstract
Grinding is applied widely in manufacturing of high-precision component. And, pursuing the forming mechanism, together with predicting topography characteristics and roughness of the grinding surface, is becoming more and more important in improving the grinding quality. The grinding surface is formed by the interaction between the grinding wheel and the workpiece. And, its topography is influenced by the grain shape, grinding wheel surface topography, and machining parameters. In this paper, the study started from establishing the topography of wheel surface. And, according to grinding kinematics, the grain trajectory equations were established. By applying the statistical screening methods, the actual cutting depth was determined. Then, the grinding surface topography was formed by simulating. Considering the influence of vibration in actual grinding, the surface topography of the workpiece under forced vibration was studied. The study results showed that the influence of grinding speed was significant for grinding surface topography, mainly in the influence for amplitude and frequency. Finally, the grinding experiments were used to verify the results of the simulation. The obtained experimental results confirmed that the as-proposed method worked efficiently and rapidly in simulating the grinding surface topography and predicting the grinding surface roughness.
