Improvement of Stability Limit by Spindle Speed Variation
By a programed variation of the spindle speed of machine tools, it is possible to control the onset of the regenerative-type self-excited chatter. In this paper, the effect of the wave form of spindle speed variation and the practical improvement of the metal removal rate in this method are theoretically analyzed, and the results are verified by some ...

Variation Spindle Speed for the Suppression of Chatter in Milling
In metal machining, regenerative chatter seriously affects tool life, part surface quality and cutting efficiency. To suppress chatter generated during milling, researchers have proposed a variable spindle speed technique. But the previous VSS milling model is based on two degrees of freedom system (two-DOF).

Integration of dynamic behaviour variations in the stability lobes method: 3D lobes construction and application to thin-walled structure milling [PDF]
Vibratory problems occurring during peripheral milling of thin-walled structures affect the quality of the fin- ished part and, to a lesser extent, the tool life and the spindle life.
