Roughness consists of the finely-spaced deviations from the nominal surface, while waviness refers to the deviations of larger spacing. Roughness deviations lie within waviness deviations.

Surface weaviness is the repeating irregularities with spacing greater than roughness marks that result from machine deflections and vibration while surfave roughness is a texture measurement of a surface.
