5-Axis HSC Machining Center for finishing of additively manufactured Workpieces

金属增材制造是目前生产工程研究的一个非常重要的领域。它具有重大的科学和工业意义。增材制造的部件提供了非常多种可能的形状，不需要特殊的模具或工具，并且具有极好的原材料与最终部件体积的比例。然而，从中长期来看，增材制造的一个主要缺点是相对较高的表面粗糙度。技术功能表面只能通过后续的加工工艺来实现，而非功能表面通常也需要进行光滑处理以避免微裂纹。通过这种后处理，创建了制造过程链，其中后续的加工操作遵循工件的增材制造，然后完成成品和即用组件。这样的工艺链已经是凯泽斯劳滕工业大学制造技术和生产系统主席的一个重要研究领域，所要求的机床应该安装在那里。所要求的机床是专门为增材加工工件的高性能磨削、协调磨削和高速铣削而设计的五轴HSC加工中心。因此，它允许应用那些最适合增材制造工件后处理的加工工艺。利用这台机器，计划在以下领域进行研究项目：-增材制造工件的磨削（使用新颖的，创新的工具概念）-增材制造工件的高速铣削-增材制造工件加工过程冷却的研究-增材制造工件的表面处理-增材制造模具和工具的后处理。凯泽斯劳滕工业大学没有类似的机器。因此，采购是计划研究项目的核心要求。

Additive manufacturing for metals is currently a highly important area of production engineering research. It is of great scientific and industrial relevance. Additively manufactured components provide a very high variety of possible shapes, require no special molds or tools, and have an excellent ratio of raw material to final component volume. However, a major disadvantage of additive manufacturing, which will persist in the medium- and long-term view, is the comparatively high surface roughness. Technical functional surfaces can only be achieved by subsequent machining processes and non-functional surfaces often need to be smoothed to avoid micro-cracks as well. Via this post-processing, manufacturing process chains are created in which a subsequent machining operation follows the additive manufacturing of a workpiece before a finished and ready-to-use component is completed. Such process chains already are an important field of research at the Chair of Manufacturing Technology and Productions Systems at TU Kaiserslautern, where the requested machine tool shall be installed.The requested machine tool, a 5-axis HSC machining center, is specially designed for high-performance grinding, coordinated grinding and high-speed milling of additively manufactured workpieces. It thus allows the application of those machining processes that are best suited for the post-processing of additively manufactured workpieces. With this machine, research projects are planned in the following fields:- Grinding of additively manufactured workpieces (using novel, innovative tool concepts)- High-speed milling of additively manufactured workpieces- Investigation of process cooling in the machining of additively manufactured workpieces- Surface conditioning of additively manufactured workpieces- Post-processing of additively manufactured molds and toolsA comparable machine is not available at TU Kaiserslautern, so that the procurement is a central requirement for the planned research project.
