Machining Grinding; Machining is one bulk material removal process (i.e. high MRR). Thus it is economical and suitable to give proper size and also for semi-finishing. Grinding has low material removal rate and is preferred only for finishing. Accuracy and tolerance achieved by conventional machining operations are not so good.

Evan Doran. Assistant Editor. 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.

Abstract. Abrasive flow machining (AFM) is a fine finishing process for difficult to reach internal surfaces through the action of extrusion pressure, combined with the abrading action of the polymer media laden with abrasive particles. To improve the material removal and surface finishing, various variants of AFM process have been developed.
