Surface Finish can be said as the surface texture or surface topography. In Mechanical Engineering Surface finish and the surface roughness, both are referred to same. Surface Roughness is finely spaced surface irregularities. Lay is simply the pattern directions which are produced from the different operations.

Rt = Roughness Tool in microns. N = New ISO (grade) scale numbers. In our grinding shop, we most commonly discuss surface finish standards of 64RMS and 32RMS. Our standard Blanchard ground finish is 64RMS and our standard surface grinding finish is 32RMS. PGI standard machining surface finish is 125RMS unless otherwise specified.
