WebApr 6, 2024 · Consequently, though mean roughness can easily be captured through one—or a few—profiles for standard manufacturing processes (those which leave a single texture orientation), optical areal measurement becomes mandatory to properly evaluate the surface in many cases. Surface roughness can be regarded as the quality of a surface of not being smooth and it is hence linked to human (haptic) perception of the surface texture. From a mathematical perspective it is related to the spatial variability structure of surfaces, and inherently it is a multiscale property. It has different … See more Surface roughness, often shortened to roughness, is a component of surface finish (surface texture).
