Dynamic analysis and control

Abstract

All machining processes are subject to dynamic effects due to transient or forced vibrations, and dynamic mechanisms inherent to the process such as regeneration. If not controlled, they may result in high amplitude oscillations, instability and poor quality. Dynamic rigidity of the structures involved in the machining is very important in determining the dynamic behavior of the process. Structural rigidity is also critical for deformations, and dimensional quality of machined parts. In this chapter, important aspects of the machining process dynamics will be discussed, and the methods that can be used for the analysis and modeling of the machine tool structural components and the processes will be presented. Chatter stability and suppression methods will also be explained with applications.
