【摘要】：对过程阻尼效应在钛合金铣削加工中的应用进了行研究。利用隐式龙格库塔法,计算典型钛合金材料铣削加工中干涉产生的侵入面积以及阻力,建立考虑过程阻尼效应的非线性铣削动力学模型,并基于此模型设计减振后角抑制颤振。计算与试验结果对比分析表明,所建模型能够较为准确地预测稳定性极限,过程阻尼效应可使低速区极限切深显著增加,而减振后角可使过程阻尼效应增强,进一步拓展稳定区域。
[Abstract]:The application of process damping effect in titanium alloy milling is studied. By using implicit Runge-Kutta method, the invading area and resistance caused by interference in milling of typical titanium alloy materials are calculated, and a nonlinear milling dynamic model considering process damping effect is established. Based on this model, the damping angle is designed to suppress flutter. The comparison and analysis of the calculated and experimental results show that the model can accurately predict the stability limit, the process damping effect can significantly increase the limit tangent depth in the low speed region, and the damping effect can be enhanced by the damping angle. Further expand the stable area.
