Ra RMS Surface Roughness Calculation
The electropolishing process may improve a surface finish by up to 50%. The electropolishing reaction removes material while it improves surface roughness. Because of the material removal, process runtimes are often limited to maintain dimensional tolerances. Limited runtimes result in real world surface roughness improvements from 10 to 35%. Remember, electropolishing improves a surface .

Grinding and finishing processes
· The selection of grinding wheels for high performance grinding appliions is focused on three basic grinding regimes, namely: rough, finish, and fine grinding. The grain size of the grinding wheel is critical in achieving a specified workpiece surface roughness. The grain size is specified by the mesh size of a screen through which the grain can just pass while being retained by the next ...
Hardness testing insight |
It can be difficult to obtain planeparallel surfaces during preparation for the hardness test. Also, the indenter should be perpendicular to the test surface. For the Vickers hardness test, the measured diagonals should not deviate more than % from each other. For the Knoop hardness test, the two halves of the long diagonals must not differ by more than % from each other.

· Grinding is often a final machining step to achieve desired surface finish or final dimensions. Grinding is a highenergy process where a lot of frictional energy is concentrated over a small region [1]. This localized energy is confined to the surface layers of the part being ground, resulting in a local rise in the surface temperature. Depending on the increase in temperature, changes in the ...
