Modélisation des efforts de coupe en taillage d'engrenages à la fraise-mère

Abstract : This study introduces a global approach for the modeling of the cutting forces generated during the hobbing process in order to improve the geometrical accuracy and quality of the manufactured part. A model to predict the cutting forces generated during gear hobbing is presented. It is based on several steps: tool/part intersection step, 2D numerical simulation based on the FE ALE method and finally the last step called '3D mechanistic simulation'. The interest of the suggested approach is to be able to avoid machining tests in the case of this very complicated operation (huge dimensional parts, kinematic, chip formation process, etc... The results are presented in terms of the analysis of cutting forces evolution and the obtained chip characteristics during the hobbing operation.
