铣削过程颤振稳定性分析的研究进展

综述铣削过程颤振稳定性分析的研究概况和进展。颤振建模和稳定性分析是该方法两个关键环节。依据颤振形成的物理条件，将其分为摩擦型颤振、振型耦合型颤振和再生型颤振。从切削过程的非线性和切削系统的非线性两方面，重点介绍再生型颤振的非线性建模的研究成果。稳定性分析方法根据对颤振模型的求解方法，分为频域法、离散法及数值法，概括了各个方法的特点、效果及适用工况。最后介绍了近来兴起的微细铣削研究领域中颤振稳定性分析的研究成果。由于其尺度效应，微细铣削加工具有独特的加工机理和特点，颤振建模中需考虑的因素与传统铣削多有不同，但稳定性分析方法仍大多沿用传统铣削中的方法。

Research Review of Chatter Stability Analysis in Milling Process

Literature on chatter stability analysis in milling process is reviewed. Chatter modeling and stability analysis is two key procedure of the method. The mechanisms leading to chatter can be classified as dry fiction effect, mode coupling effect and regenerative effect. Nonlinear regenerative chatter modeling is mainly introduced according to nonlinearity in cutting process and spindle-holder-tool system. Stability analysis is divided into three categories, i.e. frequency domain method, discretization method and numerical simulation method based on the way dynamic model is solved. The feature and applicable situation of each method is generalized. The research findings of chatter stability analysis during micro-milling are introduced in the end of the paper. Due to its size effect, micro-milling has its unique cutting mechanism and characteristics. Compared with milling, the factors considered in micro-milling chatter modeling are different and the methods of stability analysis are mostly similar.
