对高速切削过程中产生的应力波进行了可视化演示，研究了应力波的非线性传播特性与切削速度的关系。采用时间分辨光弹性成像技术，在明场模式下观察工件中的应力波，并对所获得的光弹性图像进行半定量评价。实验结果通过晶格模型定量再现，这有助于通过分析应力波的叠加来解释我们的观察。进一步模拟发现，随着切削速度的增加，刀具附近工件的应力强度并不是线性增强的过程，在不同应力波分量的叠加下，应力场发生强烈的畸变。这有助于我们对应力波作用下的HSC机理有更深入的了解。
Stress waves induced by high speed cutting (HSC) were demonstrated visually, and the dependence of their nonlinear propagation characteristics on cutting speed was studied. The time-resolved photoelasticity imaging technique in the bright-field mode was used to observe stress waves in the workpiece, and the obtained photoelastic images were evaluated semi-quantitatively. The experimental results were quantitatively reproduced via the lattice model, which helped explain our observations by analyzing the superposition of stress waves. According to the further simulation, we find that as the cutting speed increases, the stress intensity of the workpiece near the cutting tool is not in a linear enhancement process, with strong distortion of stress field under the superposition of different stress wave components. These help us have a deep understanding about the HSC mechanism under stress waves' effects.
