Ra vs rz surface roughness

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-… WebRoughness affects various part characteristics, including the amount of wear, the ability to form a seal when the part makes contact with something, and the ability to coat the part.
