Preface
Machining dynamics is a very old topic on manufacturing processes with consideration of cutting interruption, intermittency, and the coupled interaction between the tool- and work-piece for a better understanding of the underlying physics dictating material removal. In this book, cutting is treated as a nonsmooth system composed of three continuous dynamical subsystems. The corresponding boundaries are (1) the tool- and work-piece contact/impact boundary, (2) the onset/disappearance of cutting boundary, (3) the chip/tool friction boundary, and (4) the chip vanishing boundary. The complex motions in cutting dynamics are mainly caused by discontinuities, including chip and tool-piece seizure and complex stick–slip motion. Through the application of discontinuous system theory, a comprehensive understanding of the grazing phenomena induced by the frictional-velocity boundary and the loss of contact between the tool- and work-piece are discussed. Significant insights are to control machine-tool vibration and to develop chatter-free machine-tool concept. The coupling, interaction, and evolution of different cutting states to mitigate machining instability and to enable better machine-tool design are addressed in this book. The monograph presents a sound foundation upon which engineering professionals, practicing and in-training alike, could explore with rigor to make advance in manufacturing, machine-tool design, and machining chatter control. Research professionals in the general areas of nonlinear dynamics and nonlinear control would
