Suppress the vibration of tool system in milling process

A nonlinear energy sink (NES) is used to suppress the vibration of the tool system in milling operations. The corresponding theoretical analysis is done on the nonlinear vibration absorption characteristics of NES. First, the dynamic model of the milling tool system and the milling force are analyzed. The dynamic model and equation of the tool-NES system are then deduced. The approximate analytical solution is solved by the harmonic balance method, and the correctness of the analytical solution is verified by the numerical solution. The numerical simulation reveals the suppression effect of NES on the transient vibration and steady vibration of the tool system.
