摘要

线材 DED-LB/M AM 工艺速度快、成本低，可制造出高质量、高密度的零件。然而，由于工艺稳定性需要复杂的监控设备和工具，其工业应用受到限制。这项工作提出了一个双重策略来解决这个问题：一个快速运行的基于物理的模拟工具可以计算单壁构建过程中的温度场，而一个经济实惠的基于视觉的监控系统可以捕捉熔池尺寸，这些尺寸与温度相关，并显示热量积累情况。因此，实时工艺稳定性控制得以实现。红外热像仪用于验证模型和校准监控系统。

Addressing the challenge of process stability control in wire DED-LB/M process

The wire DED-LB/M AM process is fast, cost-effective and it creates high-quality, dense parts. However, its industrial adoption is limited since process stability needs complex monitoring devices and tools. This work proposes a twofold strategy to resolve this issue; A fast-running, physics-based simulation tool calculates the temperature field during the building of single walls, while, an affordable vision-based monitoring system captures the melt pool dimensions that are correlated to the temperature and reveal heat accumulation. Therefore, real-time process stability control is enabled. An infrared thermal camera is used to validate the model and calibrate the monitoring system.
