This paper describes an analytical prediction system for flank wear, which is based on the wear characteristic equation verified experimentally in the previous paper, and enables to simulate wear progress of the flank wear of tungsten carbide tools in turning plain carbon steels without built-up edge. Finite difference temperature analysis, assuming a single shear plain cutting model, is conducted by changing flank frictional stress distribution until constant wear rate is achieved everywhere on the flank wear land. Predicted tool life, temperature and stresses on the flank wear land are all in reasonable agreement with their experimental results, even in changing cutting speed, feed and material cut. The system of analytical prediction, therefore, bears practical usage, though the system is so elemental and crude at present that it must be refined in many respects.
