| Abstract: | Based on thermo-elastic-plastic finite element equation for simulating the metal cutting process, a coupled thermo-mechanical model with regard to plain strain metal cutting is constructed under some assumptions. The trend that drill thrust and torque changed with amount of feed was studied. Meanwhile the drilling process of hard-to-cut material 1Cr18N i9Ti is simulated, and the result of simulation is analyzed and discussed. This coupled thermo-mechanical model is proved to be correct by comparing the simulated results with the experimental data. |
