Cutting dynamic force modelling of endmilling operation

In the paper, a mechanistic cutting force model was suggested and the result was predicted in cutting process. The experimental coefficient modelling method was developed for the formulation of theoretical cutting force by considering the specific cutting force coefficient. Also, the specific cutting force that is the multiplication of specific cutting force coefficient and uncut chip thickness was used for the calculation of estimated force in endmilling in each direction. In this study, the cutting force mechanics of endmilling process are presented for theoretical force model in simple endmilling operations by considering the geometric shape of the workpiece part and it was compared with the measured force. As a result, the model presented shows a good consistency with the real measured force and the suggested model can be used for the prediction of force history in endmilling operation which has a different and complex conditions of start and exit immersion angle.
