Machine tool chatter suppression using spindle speed variation
… be achieved in a boring process (2 DOF) when the speed of the spindle is modulated sinusoidally instead of being kept constant. Since the variation of spindle speed is small and independent of the tool motion, by expanding the delay terms about a finite mean delay and augmenting the system, the …

Dynamics and Stability of Parametrically Excited Gyroscopic Systems
… of this simpler system shows that periodic variations in the delay may lead to larger stability boundaries. These results are applied to demonstrate that greater depths of cut may be achieved in a boring process when the speed of the spindle is modulated sinusoidally instead of being kept …
