Machine tool chatter suppression using spindle speed variation
… In [2] authors present a technique to suppress chatter, where spindle speed is varied as piecewise constant uniform noise. Using the results of vector case, we attempt to see whether stabilization can be achieved by varying spindle speed as a two state Markov chain. We find that the noise …

Vibration Control for Chatter Suppression with Application to Boring Bars
… control the self-excited oscillations known as chatter that occur when single-point turning a rigid workpiece with a flexible tool. The nature of this manufacturing process, its complex geometry, harsh operating environment, and poorly understood physics, present considerable challenges to the …

Modeling and robust adaptive control of metal cutting via application of piezoactuator
Self-excited vibration, so called chatter, is known to cause detrimental effects on the machined surface finish and to decrease the machining efficiency. Because of the small amplitude, high frequency properties of chatter, it requires active vibration control providing a force to the cutting …
