Simulation and Experiment Study of the Turning Regenerative Chatter for Nickel-based Superalloy GH4169 with PCBN Tool

  • 摘要: 针对PCBN刀具车削镍基高温合金GH4169中颤振对加工效率和质量的影响,建立一种根据切削参数有效判定切削状态的方法。首先建立了二自由度外圆车削再生颤振模型,然后利用锤击法对数控车床的刀具系统进行模态试验,测定了1阶频率、模态阻尼、模态刚度、模态质量等模态参数;设计了二自由度外圆车削再生颤振MATLAB/Simulink仿真模型,根据仿真结果预测了稳定极限切削深度和颤振的主振方向。最后利用PCBN刀具进行变切深试验。试验结果表明,仿真模型正确。
