摘　　要：在铣削过程中,由于系统模型的非线性和复杂性,加工过程参数很难控制。利用matlab软件,对铣削过程中主轴转速和轴向极限切削深度的关系进行了仿真,分析了系统切削参数对切削稳定性的影响。由仿真结果知,轴向极限切深随着主轴转速的增大呈现周期性变化,系统径向切削参数增大使轴向极限切深变小,增大系统阻尼使轴向极限切深增大。Because of the non-linear and complexity of the milling system model, it is hard to control the milling process parameters. The Matlab software is used to simulate the relationship between the spindle speed and the axial limiting cutting depth, and the effect of cutting parameters on cutting stability is analyzed. As the simulation results, with the increasing of the spindle speed, the axial limiting cutting depth changes periodically, adding the radial cutting parameters makes that the axial limiting cutting depth will be decreased. And, adding the system damp can lead to the increasing of the axial limiting cutting depth
