【摘要】：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。
[Abstract]:This paper summarizes the research and progress of flutter stability analysis in milling process. Flutter modeling and stability analysis are two key links of this method. According to the physical conditions of flutter formation, flutter is divided into friction flutter. Vibration mode coupled flutter and regenerative flutter, from the two aspects of the cutting process and cutting system nonlinear. The stability analysis method is divided into frequency domain method, discrete method and numerical method according to the solution of the flutter model, and the characteristics of each method are summarized. Finally, the research results of flutter stability analysis in the field of micro-milling are introduced. Because of its scale effect, micro-milling has a unique processing mechanism and characteristics. The factors to be considered in flutter modeling are different from those in traditional milling, but most of the stability analysis methods still follow the traditional milling methods.

【正文快照】： 铣削加工过程中刀具与工件间的相对振动,是降低产品的精度及表面质量,影响生产效率的主要原因。颤振是在切削过程中,在无周期性外部激振力持续作用下由于加工系统本身特性所引起的一种切削振动,一般表现为金属切削过程中刀具与工件之间强烈的相对振动。颤振的发生降低了切削用
