WebMay 26, 2014 · 1. Fitting. The first step in dealing with surface finish or surface “texture” is removing the underlying “shape”. In many cases the surface to be measured is tilted relative to the measuring device. In other cases, the surface may be nominally curved. In either case, the underlying geometry must be removed. WebMay 13, 2024 · Surface finish is the process of creating the desired surface roughness on a fabricated part. It is the result of the manufacturing processes used and can have a major impact on the function, aesthetics, and durability of the final product. However, achieving precise surface roughness seems not very easy and may be costly.
