Control of Cutting Vibration and Machining Instability

This book explores innovative methods for managing machine tool vibrations and machining instability, offering insights into nonlinear control theory and cutting dynamics.

In Control of Cutting Vibration and Machining Instability, the authors delve into the complexities of machine tool vibration control, emphasizing the significance of discontinuous dynamical systems. The book addresses machining instability, a critical topic in manufacturing, and highlights the limitations of previous studies that often relied on linear assumptions. By integrating recent advancements in signal processing, nonlinear dynamics, and control theory, the authors present a comprehensive framework for understanding and managing these challenges.

The text establishes the essential principles of cutting mechanics and machine tool dynamics within a simultaneous time-frequency domain. The innovative nonlinear control theory introduced by the authors enables the simultaneous management of vibration amplitude in the time domain and spectral response in the frequency domain. This dual approach lays the groundwork for developing a robust controller architecture that can effectively handle dynamic instability, including phenomena such as bifurcation and chaos.

By identifying the parameters that govern the interactions between cutting states, tools, and workpieces, the book provides a pathway to create a control methodology that mitigates machining instability. This is particularly relevant for high-speed micro- and nano-machining applications, where precision is paramount. Control of Cutting Vibration and Machining Instability serves as an invaluable resource for those seeking to deepen their understanding of cutting dynamics and develop effective strategies for chatter-free machine tool design.
