International Comparison of Surface Roughness and Step Height …

Surface roughness, often shortened to roughness, is a component of surface finish (surface texture). It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth. In surface metrology, roughness is typically considered to be the high-frequency, short … WebMaximum profile valley depth indicates the point along the sampling length at which the profile curve is lowest. * Valleys are determined for each region that falls below the average line.
