Fine grinding is one of the grinding operations that uses the face of the grinding wheel, but also uses the kinematics of a lapping operation. Fine grinding has a constant pressure between the workpiece and the grinding wheel [7]. This project will focus solely on this operation and will be explained extensively later on.
