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.
