为了从稳态切削试验中预测动态切削力，通过分析方法建立了切削颤振的数学模型。该模型是从一个伪静态的几何配置的切削过程中考虑到的事实，即平均摩擦系数波动动态响应的相对速度的变化的芯片工具接口。通过推导得到的力函数可用于解释与颤振相关的所有三种基本力学，即速度相关、再生和模式耦合效应。
A mathematical model of machining chatter has been developed through an analytical approach in order to predict dynamic cutting force from steady-state cutting tests. The model is derived from a pseudo-static geometric configuration of the cutting process by taking into account the fact that the mean friction coefficient fluctuates dynamically responding to variation of the relative speed on the chip-tool interface. The force functions through this derivation can be used to explain all three basic mechanics associated with chatter vibration, namely, velocity dependent, regenerative, and mode coupling effects.
