Closely (finely) spaced irregularities on the surface. It's results from machining operations in case of machined surfaces.
Above statement mentioned about ___________________
Roughness
Waviness
Lay
Widely spaced irregularities on the surface. It may be the result of warping, vibration or the work being deflected during machining.
