The thermo-energetic evaluation of machine tools, primarily focusing on the tool and its chuck, is very important for manufacturing accuracy. The temperature fields in the cutting tool and the clamping system can be intentionally influenced by air cooling. The cooling influence cannot be readily evaluated in practice. However, making use of simulation models, it is possible to identify the most essential parameters and to propose process-related optimal input variables. In these models, the relevant air fluxes around the tool have to be considered. The challenge is to define all of the boundary and transfer conditions. The simulation model can be verified by experiments, which, in turn, make it possible to substantiate the outcomes at relevant positions.
