摘　　要：为了更加准确地研究磨削加工机理及预测磨削结果,测量并重构单层钎焊CBN砂轮的表面形貌,并以此为基础研究不同工艺参数下的单颗磨粒切厚分布特征。结果表明:试验砂轮表面磨粒高度的分布形态并不符合正态分布特征,需要采用Johnson变换重构整个砂轮表面的磨粒高度分布特征;单颗磨粒切厚分布特征受磨削参数和砂轮磨损的影响较大。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.
