Testing Project: Surface roughness
Surface roughness is usually shortened to roughness and is a component of surface texture. It is quantified by the deviation of the normal vector direction of the real surface from its ideal form. If these deviations are large, the surface is rough; If they’re small, the surface is smooth. In surface measurement, roughness is generally considered to be the high frequency short-wave length component of measuring scale surface. In practice, however, it is often necessary to know the amplitude and frequency to ensure that the surface is suitable for a purpose.
