摘要 基于导纳耦合分析法,建立高速轴—夹具—刀具系统模型,得到不同转速下刀具端点处的频响函数,并采用半离散分析法,对变刚度铣削加工过程的稳定性进行分析,研究主轴转速对铣削稳定性的影响。结果表明,考虑轴承变刚度的影响,在高速情况下铣削加工稳定曲线向低转速方向偏移,且临界铣削深度明显降低。 Based on the admittance coupling method, the model of spindle-holder-tool system was established to obtain the frequency response function of the tool tip at different rotational speeds. Using semi-discretization method, stability of a milling machine with variable stiffness of bearings was analyzed. Influence of the rotational speed of the spindle on the stability of the milling process was studied. Results showed that in the case of high-speed milling, the stability curves of orocessing shifted toward the tow-speed range, and the critical milling depth was significantly reduced.
