本文的目的是阐明刀具与工件之间相对滑移较小的接触状态下的表面光顺过程。研制了内熨烫装置，用于观察加工过程中的表面情况。观察发现，表面光滑过程主要发生在从接触区入口处开始的很短的接触长度范围内，此时块体材料处于弹性状态，表面层的塑性变形可以显着地促进表面光滑过程。表面粗糙度随压下量的增加而减小，干燥状态下达到Ra=0.0 1μm，初始表面粗糙度Ra约为0.0 7μm时，表面粗糙度下降30%，表面光顺过程可用滑移线场理论来解释
The purpose of this paper is to clarify the surface smoothing process under contact states with a small relative slide between the tool and workpiece. An internal ironing apparatus was developed to observe the surface during the processing. Observation revealed that the surface smoothing process is largely developed during a very short contact length from the entrance of the contact zone where the bulk material is in the elastic state and can be markedly promoted by the plastic deformation in the surface layer. It was also confirmed that the ironed surface roughness decreases by increasing the ironing reduction in thickness and reaches the surface roughness of container R a =0.01 μm under dry condition and 30 percent in the reduction when initial surface roughness R a is about 0.07 μm. The surface smoothing process could be understood by the slip-line field theory
