There are several aspects of the surface to be considered in measuring surface finish. Surface Roughness vs. Surface Finish Surface roughness measurement is a quantitative assessment of very closely occurring surface irregularities, and is sometimes used interchangeably with the term surface finish measurement. There is a difference in context, however: while surface roughness is a general term about the amount of surface variation (at a very small scale) on any given surface, whether natural, man-made or found, " surface finish" is a term implying a...
