基于3J33C弹性合金小孔镗削温度测量实验及Advant Edge有限元温度仿真试验,验证了有限元模型及结果的可靠性,得到其不同镗削参数时基体最高温度的变化规律及温度范围。基于有限元仿真结果建立了3J33C小孔镗削的温度经验公式,结果表明,随着镗削转速、进给速度及径向切深的增大,镗削温度都呈现升高趋势,并且在这三个因素中镗削转速影响最大,进给速度影响次之,径向切深影响最小。
Based on the measurement experiment of hole boring temperature of 3J33C alloy and Advant Edge finite element temperature simulation, the reliability of the finite element model and the result are verified. The variation law and temperature range of the maximum temperature of the base body under different boring parameters are obtained. Based on the finite element simulation results, an empirical formula of boring temperature of 3J33C hole was established. The results show that the boring temperature shows an increasing tendency with the increase of boring speed, feed speed and radial depth of cut, Among the three factors, the influence of boring speed is the greatest, followed by feed speed and radial cutting depth is the least.
