目的：通过引入坡变换，揭示表面测量中形态学操作的本质。创新点：引入坡变换，将空间域的形态学膨胀操作转换为坡域的加法操作，揭示结构元素对表面轮廓坡度和曲率的改变。方法：1.基于坡变换理论，空间域的切膨胀操作对应于坡域的加法操作（图9）；2.分析圆结构元素作用于正弦波和圆的理论解；3.用不同半径的圆结构元素作用于正弦波，分析切膨胀和经典膨胀的相同和不同之处。结论：1.坡变换将形态学操作从空间域转换到坡域，可获取类似于傅立叶变换将卷积操作从空间域转换到频域的分析能力；2.切膨胀操作为经典膨胀操作的上确界，但会产生重叠区域。

With the development of precision manufacturing, the understanding of tolerance has become a research hotspot in the field of manufacturing. An adaptable design method for understanding tolerance in the precision stamping process is proposed in this study. First, fluctuations of tolerance which are caused by differences in the stamping process are analyzed, such as differences in material and thickness, which can lead to changes in the metal flow stress curve. Second, a condition-driven adaptive design method is constructed based on a monitoring system and hydraulic control system. The mapping rules between multiple dis-turbance factors and the execution strategy are established by the hidden Markov model algorithm. Third, executive parameters, such as velocity, pressure, and gaps, are calculated and optimized by the data statistics of partial tolerance fluctuations in the control module. Then disturbances of various conditions could be adaptively controlled timely and effectively by the executive parameters. Finally, the adaptive design method for tolerance of one precision stamping part is applied, and the effect of the application is proved by the optimized results.
