Abstract
Nonlinear time delay differential equations are well known to have arisen in models in physiology, biology, and population dynamics. They have also arisen in models of metal cutting processes. Machine tool chatter, from a process called regenerative chatter, has been identified as self-sustained oscillations for nonlinear delay differential equations. The actual chatter occurs when the machine tool shifts from a stable fixed point to a limit cycle and has been identified as a Hopf bifurcation. This chapter develops the computational tools to determine whether a time-delay system satisfies the Hopf criteria and demonstrates the application of these tools on a model of a machine turning process.Citation
