Presents new developments on machine tool vibration control based
on discontinuous dynamical systems Machining instability is a
topical area, and there are a wide range of publications that cover
the topic. However, many of these previous studies have started by
assuming that the behavior of the system can be linearised.
Meanwhile, there are many recent advances in the fields of signal
processing, nonlinear dynamics, and nonlinear control, all of which
are relevant to the machining stability problem. This book
establishes the fundamentals of cutting mechanics and machine tool
dynamics in the simultaneous time-frequency domain. The new
nonlinear control theory developed by the authors that facilitates
simultaneous control of vibration amplitude in the time-domain and
spectral response in the frequency-domain provides the foundation
for the development of a controller architecture universally viable
for the control of dynamic instability including bifurcation and
chaos. Once parameters underlying the coupling, interaction, and
evolution of different cutting states and between the tool and
workpiece are established, they can then be incorporated into the
architecture to create a control methodology that mitigate
machining instability and enable robust, chatter-free machine tool
design applicable in particular to high speed micro- and
nano-machining. * Presents new developments on machine tool
vibration control based on discontinuous dynamical systems *
Provides a clear and concise approach to the understanding and
control of machine tool and workpiece vibrations from an
alternative view, contributing to an in-depth understanding of
cutting dynamics and robust control of machining instability *
Equips the reader with the knowledge to understand the dynamics of
cutting and operation of machine-tool systems in different
conditions as well as the concept of cutting instability control *
Includes data examples in MATLAB coding
