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.
