2.1: Grinding Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used.

Surface Roughness Chart: Understanding Surface Finish in ...
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.

The condition of your chips is also important information. When grinding, the workpiece is ground by the cutting edges of abrasive grains, discharging fine chips. The shedding, glazing, etc. of grinding wheel occur from the relationship between this chip shape and each cutting edge of abrasive grain. This phenomenon occurs from a constant timing.

After a grinding distance of about 8 meters, when the diameter of the grinding wheel is reduced to about 45 microns, the surface finish deteriorates. At the same feed rate, reducing the depth of cut from 0.2 mm to 0.1 mm can significantly reduce the wear of the grinding wheel after grinding 10 meters to less than 10 microns.
