For influence factors and rules of machined surface roughness, we studied on the influence factors of machined surface roughness such as scallop-height, path interval, feed rate and optimum tool path.

在表面粗糙度的影响因素和影响规律方面：主要研究了残留面积高度、走刀行距、每齿进给率和最优化走刀路径对零件加工表面粗糙度的影响。

The change in the specific roll pressure of workblanks is investigated as the tool surface roughness and the relative height of workblanks are changed.

探讨了具有不同表面粗糙度的工具和相对高度毛坯，在变形时单位压力的变化情况；

The bed roughness height was expressed by the corrective height of vegetations, and the non-uniformity roughness was expressed by the variance of the height.

以植物高度表示有植物床面的粗糙突起程度，以高度的方差表示粗糙度的非均匀性。
