介绍了考虑过程阻尼影响的切削动力学模型，及切削稳定性解析求解方法；利用开发的仿真程序分别对车削和铣削的稳定性进行了仿真分析，模型与仿真程序的正确性得到了切削试验的验证。对比考虑过程阻尼影响前后的切削稳定性叶瓣图发现，考虑过程阻尼影响可显著提高低速区的稳定性极限值。考虑过程阻尼影响的切削稳定性仿真结果，可用于指导航空难加工材料的高效切削。

Introduces a cutting dynamic model considering process damping and its analytical solution to the cutting stability. Applies the developed simulation program to simulate and analyze the stability of turning and milling operations respectively, and the cutting tests verify the correctness of the proposed model and the simulated program. Compares the cutting stability lobe diagram with and without considering process damping, and finds that the stability limit is improved remarkably at low cutting speeds when the effect of process damping is considered. The cutting stability simulation approach considering process damping is applicable for high efficiency cutting of aeronautical hard-to-machine materials.
