The Basics of Surface Finish | GD&T Basics
Surface finish is highly dependent on the process used to manufacture the part, and very smooth surface finishes usually require additional processing such as grinding or polishing. Since additional processing will add additional cost, it is important that the engineer or designer does not impose unnecessarily low roughness requirements.
Eight tips for effective grinding - The Fabricator
Pushing too hard overloads and overheats the disc, causing the grains to glaze over and become smooth. The grains are no longer cutting into much weld metal, which in turn reduces spark production. Similarly, if you don't push hard enough, the grains don't fully engage the workpiece, so they don't remove much weld metal with every disc rotation. 4.

Surface Roughness Chart: Understanding Surface Finishes ...
Surface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.
