Research on surface topography reconstruction and distribution of undeformed chip thickness of monolayer brazed CBN wheels

In order to better understand the grinding mechanism and predict the grinding results for the further work,the actual distribution characteristics of undeformed chip thickness of monolayer brazed CBN wheel are investigated based on surface topography reconstruction.The results show that,grain height does not distribute normally,which requires Johnson transformation to reconstruct the surface topography of the whole CBN wheel.Moreover,grinding parameters and wheel wear have a great impact on the distribution of the undeformed chip thickness.
