摘　　要：基于结构动力学原理,考虑铣削系统动态特性对铣削稳定性的影响,建立了铣削加工Cr12MoV的动力学模型和稳定域的预测模型.在此理论基础上,应用Matlab软件进行不同铣削方式的数值模拟,分析获得切削系统的稳定性叶瓣图;利用Cr12MoV进行铣削振动试验,研究铣削方式和铣削速度对试件表面粗糙度的影响规律,试验结果与模拟仿真的叶瓣图进行对比,从而验证稳定性叶瓣图和理论模型的正确性.Based on the theory of structural dynamics,considering the effect of dynamic characteristics of the milling system and the Cr12MoV machining dynamics model and the stable lobes of the prediction model is established.Based on this theory,the different milling methods are numerical simulated with Matlab software,the cutting system stability lobes diagram was obtained;the use of Cr12MoV milling vibration experiment,The influence of milling methods and milling speed on the surface roughness of the specimens is studied,experimental results and simulate the lobes were compared in order to verify the correctness of the stability lobes diagram and theoretical model.
