Chatter suppression in milling processes using periodic spindle speed variation

Résumé

Spindle speed variation is a well known technique to suppress regenerative machine tool vibrations, but it is usually considered to be effective only for low spindle speeds. In this paper, the effect of spindle speed variation is analyzed in the high-speed domain, for the spindle speeds corresponding to the first flip (period doubling) and to the first Hopf lobes. The optimal amplitudes and frequencies of the speed modulations are computed using the semi-discretization method. It is shown that period doubling chatter can effectively be suppressed by spindle speed variation, while the technique is not effective for the quasi-periodic chatter above the Hopf lobe. The results are verified by cutting tests.
