Grinding can also be considered as a machining process, i.e. process of removing metal, but comparatively in smaller volume. To grind means 'to abrade', to wear away by 'friction' or 'to sharpen'. In grinding, the material is removed by means of a rotating abrasive wheel. The action of grinding wheel is very similar to that of a milling cutter.
