Modelling and simulation of nozzle guide vanes considering mechanic-thermal loads of grinding

The knowledge about the complex workpiece-fixture behaviour during machining is essential for the fixture development process. Therefore, the forces acting on fixture components have to be analysed. In this thesis, a method for predicting the reaction forces due to clamping and process loads is presented. First, a complex finite element model is used for getting detailed information about the behaviour during the process. Secondly, a faster model with less elements is developed, validated and used for the variation of process parameters. Finally, both results are combined to an analytical model. This empiric equation provides the opportunity to predict the reaction forces depending on several process parameters. The usability of this method has been exposed by modelling shape grinding of a nozzle guide vane.
