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.

在航空航天工业的结构部件制造中，挑战是生产具有相对较低壁厚的非常大的产品，同时保持高尺寸和表面要求。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的废品或高返工成本。在优先计划1480中，跨学科合作开发了一种模型，该模型可以预测和补偿复杂结构部件加工中的热和机械引起的变形以及相关的形状偏差。在拟议的知识转移范围内，优先计划1480的科学成果被调整和转移，用于优化Premium AEROTEC GmbH公司的制造工艺。项目完成后，Premium AEROTEC将能够更精确地预测结构部件的生产质量，并相应地调整刀具路径。这通过废品和必要的返工降低了成本。
