But it is pity that few of them yield practical and valuable achievement as yet. The essential reason is that the common foundation of all these models was based on the actual measurement of specific wheel topography. So it didn’t have universal applicability. Considering that the absolute irregular distribution of grains is not the requirement of the grinding process, contrarily it will bring much negative influence to grinding process. By conversely reasoning, a new conception on the relatively regular and reasonable distribution of grains on the wheel surface in accordance with different machining demands is put forward in this paper, and furthermore a creative idea of optimization design of grinding wheel topography in accordance with machining demands and grinding parameters as well as the optimization of grinding parameters in accordance with machining demands and grinding wheel topography is proposed. In the light of this idea, not only the modeling and simulation of grinding process can be really carried out, but also the optimization of grinding process and the estimation of grinding results can be realized straightway. In conclusion, a superabrasive slotted grinding wheel is designed as a practical application of the optimization model and a creep feed deep grinding experiment is carried out to verify the optimization results.展开更多
