There are generally three main mechanisms that drive the grinding process: cutting, plowing, and sliding. The cutting mechanism occurs when the abrasive grinding wheel can effectively penetrate the workpiece and remove material. There is sufficient clearance for the chip to flow away via the coolant flow and wheel movement.
