Self-excited vibrations in milling process are probably one of the most important obstacles to increase the material removal rate (MRR). In order to avoid chatter, some authors have proposed the use of strategies aimed at disturbing the excitation caused by the periodic strike of the teeth on the workpiece. One of these techniques, spindle speed variation (SSV), would be presented in this article. After a brief revision of the state-of-the-art in application of SSV techniques, a numerical cutting model is developed and modified to include the capability to simulate the SSV. Finally, a comparative analysis of spindle speed variation techniques is presented based on computer simulations.
