Additional information
Chatter instabilities that arise during high-speed machining are a key limitation to manufacturing. Turning process can be modelled as implicit state-dependent delay differential equation. This predicts Hopf bifurcation as primary stability loss mechanism; however, at high speeds criticality of bifurcation changes, resulting in less-dangerous stability loss. To detect these changes, novel numerical methods were developed. This has sparked range of new methods to investigate this type of problem. Paper is in top 1% of most-cited in journal within REF period (Web of Science, 8/3/2013).
