Abstract
Chatter prediction is nowadays frequently carried out for machining operations involving deformable parts or tools. These analyses are commonly based on the uncoupled elements of the system: frequency response of the deformable parts under non-rotating conditions and cutting law. The present investigation puts forward the dynamics of a thin-walled tubular part during straight axial turning undergoing chatter instability. Studied system’s peculiarities include quasi-static nominal cutting conditions and twin flexural modes featuring strong variation of modal characteristics along the pass. The measurement records, based mainly on fixed-frame non-contact eddy-curr...
