TL;DR: In this article, the authors examined the link between chatter instability and surface roughness evolution for thin wall milling and developed an explicit numerical model to solve the nonlinear system of delay differential equations.

TL;DR: In this article, the effect of spindle speed variation is analyzed in the high-speed domain for spindle speeds corresponding to the first flip (period doubling) and the first Hopf lobes.

TL;DR: In this paper, the authors evaluated the machining vibrations of thin-walled aluminium work-pieces at high productivity rate using a specially designed machining test with high cutting engagement and taking into account all the phenomena involved in the dynamics of cutting.

TL;DR: In this article, the authors investigate theoretically and experimentally the potential of a vibro-impact type nonlinear energy sink (VI-NES) to mitigate vibrations of a linear oscillator (LO) subjected to a harmonic excitation.

TL;DR: In this article, the dynamic response of a harmonically forced linear oscillator (LO) strongly coupled to a nonlinear energy sink (NES) is investigated both theoretically and experimentally, and it is shown that there is an optimal zone in the forcing amplitude nonlinear stiffness parameter plane, where SMR occurs without having a high amplitude detached resonance tongue.
