将数字散斑相关法（DSCM）和能谱（EDS）相结合的扫描电镜（SEM）三维重建技术应用于刀具磨损的研究。基于扫描电镜三维重建技术，对后刀面磨损和弧坑磨损进行了刀具磨损形态分析。利用最小二乘法得到磨损表面与参考表面的比较，从而确定磨损深度。用已知三维结构的压痕对计算结果进行了验证，结果与体积不变原理一致。结果表明，结合DSCM的SEM三维重建方法在磨损观测中是可靠的，在真实的工程应用中具有很大的优越性。
The 3D reconstruction of scanning electron microscope (SEM) combining digital speckle correlation method (DSCM) and energy dispersive spectroscopy (EDS) were introduced to investigate the wear of cutting tool. The tool wear morphological analysis for flank wear and crater wear were carried out based on the SEM 3D reconstruction. The wear loss depth was detected by comparing the wear surface to its reference surface which was obtained by using least square method. An indentation with known 3D construction was used to vaLidate the calculating results, and the results were well consistent with the principle of constant volume. It is concluded that the SEM 3D reconstruction combining DSCM is reLiable on wear observation and presents great advantages in real engineering appLications.
