Suppression of period doubling chetter in high-speed milling by spindle speed variation [PDF]
Machining Science and Technology, 2011 Spindle speed variation is a well known technique to suppress regenerative machine tool vibra- tions, but it is usually considered to be effective only for low spindle speeds.

The analysis of tool life and wear mechanisms in spindle speed variation machining [PDF]
The International Journal of Advanced Manufacturing Technology, 2014 Regenerative chatter vibrations generally limit the achievable material removal rate in machining. The diffusion of spindle speed variation (SSV) as a chatter suppression strategy is mainly restricted to academy and research centers.

Perturbation Analysis of Spindle Speed Variation in Machine Tool Chatter [PDF]
Journal of Vibration and Control, 1997 Spindle speed variation has been shown to be an effective method for chatter control. In this paper, a single-degree-of-freedom regenerative type chatter equation is treated using perturbation methods. Rather than using the time coordinate, the angle of revolution is taken as the independent coordinate for maintaining a constant delay in the equations.

Programming spindle speed variation in turning
Eastern-European Journal of Enterprise Technologies, 2017 A mathematical model for the turning process is developed, which considers the oscillations of technological machining system (TMS) in a 3D space, along all three coordinate axes simultaneously. The model accounts for the influence of natural feedback on the depth, feed and cutting speed; moreover, the effect of machining by chatter marks is introduced

Influence of material removal on the dynamic behavior of thin-walled structures in peripheral milling [PDF]
, 2006 Machining is a material removal process that alters the dynamic properties during machining operations. The peripheral milling of a thin-walled structure generates vibration of the workpiece and this influences the quality of the machined surface.
