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.
