Presents new developments on machine-tool vibration control applicable to nonlinear and discontinuous dynamical systems
Cutting instability is a temporal-spectral aberration in the simultaneous time-frequency domain. This aberration is particularly prominent at high machining speeds as it is nonlinear, nonstationary, and characteristically broadband. Irrespective of cutting speed, proper mitigation of cutting requires that vibration amplitudes in the time domain and vibration spectra in the frequency domain be simultaneously suppressed.
Micro-machining is operated in a speed range that is at least one order of magnitude higher than conventional cutting operations. As cutting at higher speeds is inherently unstable, mitigating dynamic instability in micro-machining is a pressing issue in the industry.
In this book, the authors develop powerful analytical tools essential for the characterization of cutting instability, which is inherently complex and often chaotic. It also provides effective measures for instability control, system identification, and signal processing - the three components fundamental to machine-tool design. The strategy formulated in the book, along with the control and design methodologies, is novel and unique in that it deploys simultaneous vibration and frequency control in real-time to negate manufacturing instability including machine-tool chatter.
