我们分析了正交切削过程中产生的振动。使用一个简单的再生切削的一个自由度模型，我们已经观察到系统的复杂行为。在成形切削表面的存在下，刀具和工件之间的非线性相互作用导致取决于系统参数的周期性、准周期性或混沌类型的颤振。为了描述第一次加工的表面轮廓，我们使用了调和函数。分析了刀具与工件失去接触后的冲击现象。(C)2002爱思唯尔科技有限公司版权所有。
We have analysed vibrations generated in an orthogonal cutting process. Using a simple one degree of freedom model of the regenerative cutting, we have observed the complex behaviour of the system. In presence of a shaped cutting surface, the nonlinear interaction between the tool and a workpiece leads the to chatter vibrations of periodic, quasi-periodic or chaotic type depending on system parameters. To describe the profile of the surface machined by the first pass we used a harmonic function. We analysed the impact phenomenon between the tool and a workpiece after their contact loss.
