摘要: 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。Abstract: 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.
