Abstract
A model of a passive vibration absorbers designed for improving the stability of milling tools is presented in this work, the spindle supposed exited backward and upward respectively by the motor through the gearbox and by the cutting forces through the milling tool. First a milling operation is simulated taking into account the tool cutting torque and the gear transmission varying time efforts, then a passive linear absorbers composed by a single mass-spring-damping are implemented in the spindle to study their effect on the dynamic behavior of milling tool. The obtained results show a decreasing of the vibration amplitude of the milling to reach in certain cases 42% compared to the same cutting operation without using absorbers. In addition, the same absorbers prove their efficiency to reduce the cutting time when the feed rate was doubled accompanied by a little improving of the dynamic behavior of milling tool.
