In the manufacturing of structural components for the aerospace industry, the challenge is to produce very large products with relatively low wall thickness while maintaining high dimen-sional and surface requirements. Quality issues that are only discovered during the quality control, which takes place after the production process, lead to high quantity of rejects or high rework costs. In the Priority Programme 1480, a model, which allows to predict and compen-sate the thermally- and mechanically-induced deformations in the machining of complex structural components and the associated shape deviations, was developed in interdisciplinary cooperation. Within the scope of the proposed Knowledge Transfer, the scientific results of the Priority Programme 1480 are adapted and transferred for the optimization of the manu-facturing process of the company Premium AEROTEC GmbH. After completion of the pro-ject, it will be possible for Premium AEROTEC to predict the production quality of structural components more precisely and to adapt the toolpaths accordingly. This reduces costs through rejects and necessary rework.

在航空航天工业结构部件的制造中，面临的挑战是生产壁厚相对较低的大型产品，同时保持较高的尺寸和表面要求。仅在生产过程后的质量控制过程中发现的质量问题会导致大量废品或高昂的返工成本。在优先计划 1480 中，跨学科合作开发了一个模型，可以预测和补偿复杂结构部件加工过程中热和机械引起的变形以及相关的形状偏差。在拟议的知识转让范围内，对优先计划 1480 的科学成果进行调整和转让，以优化 Premium AEROTEC GmbH 公司的制造流程。项目完成后，Premium AEROTEC 将能够更准确地预测结构部件的生产质量，并相应地调整刀具路径。这可以通过拒绝和必要的返工来降低成本。
