The aim of this subproject is to improve the process understanding in laser fusion cutting of metallic mate-rials by model- and simulation-based analysis of the highly dynamic processes in the melt. The technical objective is to produce high-precision, dross-free, high-quality cuts and to reduce the roughness of the cut edges by an order of magnitude in line with the state of the art. Modeling and simulation are used to identify and investigate measures to stabilize the melt flow and homogenize the subsequent solidification of the melt on the cutting edges.

该子项目的目的是通过对熔体中高度动态过程的基于模型和仿真的分析，提高对金属材料激光熔化切割过程的理解。技术目标是生产高精度、无浮渣、高质量的切割，并将切割边缘的粗糙度降低一个数量级，符合现有技术水平。建模和仿真用于确定和研究稳定熔体流动的措施，并使切割边缘上的熔体随后凝固均匀化。
