与形状特性有关的表面粗糙度新参数研究

Analysis of Shape-Relative Surface Roughness Parameter

叙述与微观不平度形状特性有关的表面粗糙度现有参数及其不足，给出新参数－ 轮廓支承长度率加权平均值的定义，从几何精度方面描述零件表面的支承与耐磨性能，通过实验与计算说明了新参数的实用性。

This paper briefly introduces the study of surface roughness parameters which are relative to profile shape. The weighted mean of the profile bearing length ratio was defined as a new parameter to describe the surface profile of precision machined parts. Tests and analysis showed that the parameter can be applied to characterizing the wear resistant ability of parts.
