Associate Editor, Modern Machine Shop. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.

Surface formation process. From Fig. 1(d), it can be seen that when the abrasive grain scratches the surface of the workpiece, part of the material is removed, and a scratch is left on the workpiece surface. After all the effective abrasive grains on the grinding wheel have scratched the surface of the workpiece, numerous scratches intersect each other and form a new surface morphology.
