Analyzing and optimizing the fluidic tempering of machine tool frames

Thermal stabilization of frame structures by integration of demandoriented fluidic temperature control systems offers considerable potential concerning the minimization of thermo-elastic displacements and energy requirements. Additionally, by using high performance concrete, completely new possibilities for the design-wise integration of channel structures arise during casting. Thus, heat removal can be further improved by means of fluidic circuits adapted locally to the heat sources. The paper describes a developed high performance concrete (HPC) machine tool frame with integrated fluidic fluidic circuits. A special focus is laid on on modeling the structure and developing a siutable control methodology, identifying required parameters and derriving possibilities for optimization.
