Knowledge of the correct temperature distribution on the cutting front is essential to understand and quantify the thermo-fluid dynamics during laser cutting, which are directly related to the edge quality. For that purpose, hyperspectral imaging, coupled with trim-cut observations with boundary conditions close to industrial processing, have been performed for the first time. In this paper, the experimental setup for the characterization of temperature and melt flow behavior of the cutting front is described and its use is illustrated for fiber laser flame cutting of 15 mm mild steel plates.

激光切割的高光谱成像和修剪切割可视化

了解切割前沿的正确温度分布对于理解和量化激光切割过程中的热流体动力学至关重要，这与边缘质量直接相关。为此，首次进行了高光谱成像以及边界条件接近工业加工的修剪观察。在本文中，描述了用于表征切割前沿的温度和熔体流动行为的实验装置，并说明了其在 15 毫米低碳钢板的光纤激光火焰切割中的应用。
