The Extended Milling Bifurcation Diagram

This paper describes the extended milling bifurcation diagram which can be used to gain fundamental new insights into milling dynamics. The diagram is constructed using numerical simulation techniques and provides both stability behavior (such as Hopf and period-n bifurcations) and vibration amplitudes under stable and unstable conditions. The results are compared to semi-analytical stability predictions. It is expected that the insights gained through the extended milling bifurcation diagram will reveal new milling strategies that yield increased productivity and reduced costs for subtractive, discrete part manufacturing.
