A more comprehensive orthogonal turning model is developed in order to further study the influence of feed velocity on frictional chatter. Nonlinear dynamic behavior of the cutting tool in two directions is presented by using bifurcation diagram, phase portrait, and Poincaré section. It can be found that the cutting tool has a variety of dynamic behaviors at different feed velocity and cutting velocity, such as periodic motion, quasi-periodic motion, and chaotic motion. Furthermore, the vibration displacement of the cutting tool is affected by the feed velocity, especially for relatively high feed velocity which will result in the cutting tool vibration displacement increase in the cutting direction but a decrease in the feed direction. In addition, it is clear that the stick–slip phenomenon only appears in the cutting direction in our work.

为了进一步研究进给速度对摩擦颤动的影响，开发了一种更全面的正交车削模型。通过使用分叉图，相图和庞加莱截面，展示了刀具在两个方向上的非线性动力学行为。可以发现，切削工具在不同的进给速度和切削速度下具有多种动力学行为，例如周期性运动，准周期性运动和混沌运动。此外，切削刀具的振动位移受到进给速度的影响，特别是对于相对较高的进给速度，这将导致切削刀具振动位移在切削方向上增加而在进给方向上减小。此外，很明显，在我们的工作中，粘滑现象仅出现在切割方向上。
