Surface roughness refers to the micro-geometric shape features of the machined surface of a part, which are composed of small spacing and peaks and valleys. It is a microscopic geometry error.

    So, how does surface roughness come about? The surface of parts formed by cutting or other methods always has geometric shape errors due to material plastic deformation, mechanical vibration, friction and other reasons in processing. Surface roughness has an important influence on the friction and wear, fatigue strength, corrosion resistance and the mating properties of parts.
