Abstract
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.
