| 摘 要： | 原子力显微镜(AFM)是获取金刚石刀具刃口纳米级三维形貌的重要手段,但其存在测量范围小,难以表征参与切削区域整段刃口形貌特征的问题。采用基于迭代最近点法的刃口AFM测量数据拼接算法,获得了由多组数据拼接得到的刃口纳米级三维形貌,并进行了切削实验验证。实验结果表明,采用的数据拼接方法可较好地用于表征刀具刃口三维形貌。

| Abstract: | The atomic force microscopy(AFM)is an important means to obtain the nano-scale three-dimensional profile of diamond cutting edge.However,its measurement range is small and it is difficult to represent the whole profile of cutting edge involved in cutting process.In this paper,based on the iterative closet point method,the AFM measurement data stitching algorithm is used to obtain the nano-scale three-dimensional profile of cutting edge by stitching sets of data,and the cutting experiment is done for verification.The result shows that the data stitching method used in this paper can be used to represent the three-dimensional profile of tool cutting edge well. |
