WebSep 9, 2024 · Since the surface finish requirement is 1.6 microns, national specifications recommend a cut-off value for this roughness value of 0.8 mm in length. This minimum length of 0.8 mm ensures that there is “enough roughness” to perform the mathematical calculation of roughness. WebJan 6, 2024 · Surface Finish consists of waviness, lay, and roughness, but it is common for only roughness to be specified on technical drawings. Ra is average roughness, and it under-estimates surface height variations. Rz is mean roughness depth, and it approximates the size of the most severe surface height variations. Ra < Rz in most cases.
