Shearing, ploughing, and wear in orthogonal machining

Under normal machining conditions, cutting forces are due primarily to the bulk shearing of the workpiece material in a narrow region called the shear zone. However, under certain conditions, such as finishing cuts or a worn tool, force components due to the rubbing and ploughing of the edge or wear land becomes significant. Predicting forces--and therefore other process outputs such as machined part quality--under these conditions requires an estimate of the effects of ploughing and wear. Furthermore, both ploughing and wear forces are thought to be related to machine-tool system stability through the process damping mechanism and to the machined workpiece surface properties. Little, however, is known about the effects of wear on forces, and even less on ploughing. No accepted model exists for predicting the effects of either.
