The self-excited vibration, called chatter, is one of the main limitations in metal removal
processes. Chatter may spoil the surface of the part and can also cause large reduction in …

The employment of active control devices has been demonstrated as one of the most
effective methods to suppress chatter vibrations in machine tools. However, the commonly …

This paper applies a coupled control method of LQG and robust to suppress milling chatter.
With two controllers working together, the coupled control method has strong robustness to …

Chatter phenomena commonly plague the milling process of flexible workpieces, leading to
undesirable fluctuations in accuracy and diminished machine efficiency. Limited by complex …

Abstract Machine tool productivity and part surface quality are fundamentally limited by
chatter occurring due to regenerative type self-excited vibrations. Efficacy of the existing high …

A new model-based predictive controller (MPC), specially oriented to facilitate its practical
implementation, is presented. This controller is devoted to reduce the structural load in the …

Bistabilities in turning are characterized by the process being stable for small perturbations
and unstable for larger ones. These bistabilities occur due to nonlinearities in cutting force …

During metal cutting operations performed by conventional machine tools (turning, milling...)
often appear vibrations due to the emergence of a variable force generated by the so-called …

Interruptions in turning make the process forces non-smooth and nonlinear. Smooth
nonlinear cutting forces result in the process of being stable for small perturbations and …

The employment of inertial active damping devices for chatter suppression in machining
processes has been widely studied. The main drawback is that machine tools generally offer …
