WebFeb 22, 2024 · Overall, the best surface finish measurement is Ra. It gives you the most accurate reading of the surface finish, and it’s common on a surface finishing chart. While it can help to focus on the extremes with Rmax and Rz, those are more specific. You can use those measurements if you’re trying to compare parts of a single surface. WebRMS is calculated as the Root Mean Square of a surfaces measured microscopic peaks and valleys. Each value uses the same individual height measurements of the surfaces peaks and valleys, but uses the measurements in a different formula. 1.
