Analytical prediction of chatter stability for variable pitch and variable helix milling tools
This paper describes the first accurate model of milling chatter for variable helix tools, which have the potential for an order of magnitude increase in machining productivity. The research was funded by Sims's EPSRC Advanced Research Fellowship (GR/S49841/01). Mann's (Duke University, USA) research visit was funded by a National Science Foundation CAREER award. In addition to solving the stability problem, the manuscript was the first to show the existence of period-one (cyclic fold) bifurcations for this configuration of system. The work has led to an industrially co-funded EngD studentship (contact: Manufacturing Director).
