A grinding machine uses an abrasive product — usually a rotating wheel — to shape and finish a workpiece by removing metal and generating a surface within a given tolerance. A grinding wheel is made with abrasive grains bonded together. Each grain acts as a cutting tool, removing tiny chips from the workpiece.

Normal and tangential forces are generated between the grinding wheel and the workpiece. The forces cause abrasive grains of the grinding wheel to penetrate the workpiece. A grain that cuts deeply into the workpiece carves out a chip whereas a grain that rubs the workpiece very lightly may fail to penetrate the surface.
