Abstract: The three dimensional nonlinear milling force model of tapered end mills is formulated with its geometrical features described by using the differential geometrical theory. The bi-linear optimization algorithm is implemented to identify the milling force coefficients. For verification of the validity of the model, a set of cutting test is conducted. The simulation results show a very satisfactory agreement with those obtained by the experiments.
