| Outline of Final Research Achievements |
This research has proposed a prediction system of the flow stress property of metals by analyzing cutting phenomena. In the system, the shape of chip, cutting forces and the temperature distributions on the chip back face and the chip free surface are prepared as the boundary conditions. Then, a FEA of metal cutting is conducted considering that the work hardened coefficient is unknown. By adjusting the work hardened coefficient to agree the result of the FEA with the boundary conditions, the flow stress property will be obtained. This study developed the most important system to work the system proposed, which is to establish a system of grasping the temperature distributions on the chip back surface and the chip free surface.
