WebSurface 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 ...

WebFor moving parts, usually you'll be using something like a bush or bearing which specifies the surface finish (and other things like hardness) of the mating parts. For rough parts, flame-cut, water-cut etc, it can be helpful to specify a profile tolerance all round (e.g. 0.8 mm, not micron) if the external dimensions aren't critical.
