Personal note: Despite the fact this book focus machine inner dynamics behavior, it's very useful for who needs to study in depth foundations machines.

Through this book we demonstrate the importance of considering the role of process dynamics in machining performance. We based the book on graduate courses in mechanical vibrations and manufacturing that we have previously offered, but also included aspects of our research programs in machining dynamics and precision engineering. We developed the text to be applied in a traditional 15 week course format with an intended audience of upper division and graduate level engineering students, as well as the practicing engineer.
We organized the book into seven chapters. The chapter topics are summarized here.
Chapter 1 – We provide a of list potential obstacles to machining productivity and highlight the focus areas for this text. We direct the reader to Fig. 1.1.1 for a graphical identification of these areas.
Chapter 2 - We first review the fundamentals of single and two degree of freedom free and forced vibrations. We then continue with a description of the frequency response function, including experimental techniques.
Chapter 3 – The purpose of this chapter is to describe regenerative chatter in turning and introduce the stability lobe diagram. We detail both analytical and time-domain simulations to determine stable and unstable cutting conditions.
Chapter 4 – In this chapter we focus on milling and describe the corresponding analytical and time-domain simulations for stability prediction.
Chapter 5 – Our goal for this chapter is to investigate the influence of forced vibrations during stable milling on part geometric accuracy. Both analytical and time-domain approaches are provided.
Chapter 6 - We analyze the frequency content of stable and unstable milling signals; update the time-domain simulations developed in Chapters 4 and 5 to include runout of the cutter teeth and variable teeth spacing; discuss stability of low radial immersion milling; and describe the uncertainty evaluation for stability boundaries.
Chapter 7 - In this chapter, we apply receptance coupling to prediction of the tool point frequency response function. We also review Euler-Bernoulli beam theory and provide expressions for beam frequency response functions under various boundary conditions.
