Abstract
The complex workpiecefixture behaviour during machining is an essential component of the fixture development process In detail the forces acting on fixture components have to be analysed A method for the prediction of the reaction forces due to process and clamping loads is presented in this article At the beginning detailed information about the workpiecefixture behaviour during the process is determined by a complex finite element model Secondly the reduction of the number of elements leads to a smaller model with less computation time validated and used for the variation of process parameters Finally an analytical description is developed based on the combination of both results With the help of the empiric equation it is possible to predict the reaction forces and the dependency on several process parameters This method has been validated by modelling shape grinding of a nozzle guide vane
