Identification of environment parameters of thermo-elastic models and correction algorithms based on high-dimensional characteristic diagrams (B09)

• Subject Area: Engineering Design, Machine Elements, Product Development ; Mathematics
• Term: from 2015 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 174223256

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.
