System for Laser Material Processing with High Flexibility

高度灵活的激光材料加工系统为金属加工和合金开发领域提供了新的研究机会。这种高度灵活的系统可以克服粉床系统的缺点。即使局部曲面法线不是垂直的，也可以实现零件的垂直逐层堆积。搬运系统结合了现代机器人搬运激光光学系统和倾斜旋转系统，操纵待制作的样品。因此，可以独立于局部表面法线方向来确定垂直建筑方向。这允许在设计零件时使用新的概念。此外，可能不再需要支撑结构，允许各种各样的样品几何形状。与需要以相对较小的构建速率逐层分布粉末的粉末床系统相比，所提出的系统使用了带有同轴喷嘴的粉末进料器。对于更高的建筑速率，也可以使用送丝机。本文提出的高度灵活的激光材料加工系统将是拜罗伊特大学金属与合金组非常重要的最新工具。许多新的可能性的开启将极大地促进和加强金属及合金的研究。

A high flexible laser material processing system enables new research opportunities in the field of metal processing and alloy development. The drawback of powder bed systems can be overcome with such a highly flexible system. A vertical layer-by-layer buildup of a part can be achieved even if the local surface normal is not vertical. The handling system combines a modern robot handling the laser optic combined with a tilt-rotating system, manipulating the to-built sample. Thereby a vertical building direction is possible independent of the local surface normal direction. This allows new concepts in designing a part. Additionally supporting structures might not be necessary anymore, allowing a wide variety of sample geometries.In comparison to powder bed systems, which need to distribute the powder layer-by-layer with comparatively small building rates, the proposed system uses a powder feeder with a co-axial nozzle. For even higher building rates a wire feeder can be used as well.The herewith-proposed high flexible laser material processing system will be a very important and up-to-date tool for the group of Metals and Alloys of the University Bayreuth. The opening of many new possibilities will enable and strengthen the metals and alloys research tremendously.
