“…Classical solutions are based on increasing the stiffness of the mechanical components and the damping by reducing cutting speed or by adding dampers [16]. Tools with variable pitches [17,18] or with variable helix angles [19,20] can also be used to suppress chatter.…”

To cite this version:Sébastien Seguy, Tamás Insperger, Lionel Arnaud, Gilles Dessein, Grégoire Peigné. On the stability of high-speed milling with spindle speed variation. International Journal of Advanced Manufacturing Technology, Springer Verlag, 2010, 48 (9-12) Abstract 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 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 semidiscretization method. It is shown that period doubling chatter can effectively be suppressed by spindle speed variation, although, the technique is not effective for the quasiperiodic chatter above the Hopf lobe. The results are verified by cutting tests. Some special cases are also discussed where the practical behavior of the system differs from the predicted one in some ways. For these cases, it is pointed out that the concept of stability is understood on the scale of the principal period of the system-that is, the speed modulation period for variable spindle speed machining and the tooth passing period for constant spindle speed machining.

“…It is also seen in the top two panels that, although the general trend is increased amplitude and reduced frequency with increasing overhang length, the tool point magnitudes are attenuated near 800 and 1200 Hz. This is due to dynamic interaction between the tool/holder clamped-free fundamental mode and the spindle modes at these frequencies [20].…”
