Abstract：Chatter easily occurs during the milling process of thin-walled part, and the stability limit is varied due
to the changing of part dynamics. The passive damping technology based on viscoelastic material is investigated in order
to promote the damping ratio and machining stability of the thin-walled part. A methodology consisting of damping layer,
restraint layer and mass layer is proposed. Modal tests show that it is effective in damping multiple modes. Finally, it is applied
to the five-axis milling of thin-walled S part. Experiments under multiple configurations of cutting parameters show
that the vibration amplitude is decreased by 97%.
