What's the Differences between Surface Roughness and Surface Finish !!
Abstract Surface roughness refers to the quantifiable measurement of the irregularities on a surface, while surface finish is a qualitative assessment based on its appearance or indirectly from the roughness value. However, in machine shops, it is common for the term surface finish to be used to describe only the surface roughness.

Surface Roughness: Basic concepts Surface Roughness is the measure of macro and micro asperities and irregularities present on a finished surface after machining. It is the quantitative approach to find out height of peaks and depth of valleys of surface asperities. There are various instruments to facilitate such measurement. 2.
