B09 develops a black-box thermal error correction method based on high-dimensional characteristic diagrams. The third phase focuses on the extension and improvement of the developed methods and tools for their application in complex production environments. This requires enhanced simulations with realistic transient load cases including radiation, micro-climates, coolants, chip nests and forced convection due to axis movements. Added complexity comes from the consideration of the entire machine tool including foundation and housing. A new decoupling method for fluid-dynamic simulations using characteristic diagrams will be improved and applied for more efficient machine tool thermal design optimization. The characteristic diagram based correction will likewise be adapted for realistic production environments. In order to cope with the added complexity, an alternative componentwise correction method will be developed and com-pared to the full model.

B09开发了一种基于高维特征图的黑盒热误差修正方法。第三阶段的重点是扩展和改进所开发的方法和工具，以便在复杂的生产环境中应用。这就需要增强模拟，模拟真实的瞬态负载情况，包括辐射、微气候、冷却剂、芯片嵌套和由于轴移动而产生的强制对流。增加的复杂性来自对整个机床的考虑，包括基础和外壳。一种新的解耦方法的流体动力学模拟使用特性图将得到改进，并应用于更有效的机床热设计优化。基于特性图的校正同样适用于实际生产环境。为了科普增加的复杂性，将开发一种替代的分量校正方法，并将其与完整模型进行比较。
