| 摘 要： | 研究了通过调节数控机床伺服参数，控制极限切削宽度来抑制切削颤振的新方法。文中建立了包括机械系统、伺服系统及切削颤振环节的数控机床切削系统模型。该模型全面反映了各环节间的相互影响。通过仿真分析了切削系统的稳定性，并通过实验描绘了极限切削宽度与伺服系统参数的关系曲线，为数控强力切削过程中抑制颤振提供了可靠依据。仿真和实验结果表明，数控机床伺服参数与极限切削宽度具有映射关系，文中所述方法实用、可靠。

| Abstract: | A new method for suppressing cutting chatter is studied by adjusting servo parameters of the numerical control (NC) machine tool and controlling the limited cutting width. A model of the cutting system of the NC machine tool is established. It includes the mechanical system, the servo system and the cutting chatter system. Interactions between every two systems are shown in the model. The cutting system stability is simulated and relation curves between the limited cutting width and servo system parameters are described in the experiment. Simulation and experimental results show that there is a mapping relation between the limited cutting width and servo parameters of the NC machine tool, and the method is applicable and credible to suppress chatter. |
