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.

在为航空航天行业的结构组件制造中，面临的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。仅在生产过程后发生的质量控制过程中发现的质量问题会导致大量的拒绝或高返工成本。在优先级计划1480中，一个模型允许在跨学科合作中预测和构建复杂结构组件和相关形状偏差的加工中的热和机械诱导的变形。在拟议的知识转移范围内，优先计划1480的科学结果被调整并转移，以优化公司Premium Aerotec GmbH公司的手机反对过程。专业设备完成后，Premium Aerotec可以更精确地预测结构组件的生产质量并相应地调整工具路径。这可以通过拒绝和必要的返工来降低成本。
