Surface Finish: A Comprehensive Guide to Manufacturing Surface Roughness Optimization What is Surface Finish? Surface finish, also known as surface texture or surface roughness, is a measure of the relative smoothness or roughness of a machined, cast, or molded surface or component. It is typically measured with a profilometer or a surface roughness tester, which are special instruments that measure the average height of peaks and valleys on a surface. Surface finish is often quantified by two major parameters – the average height of irregularities (Ra) and the spacing between irregularities (Rz). Ra is the arithmetic mean of the absolute…
