Influence of material removal on the dynamic behavior of thin-walled structures in peripheral milling [PDF]

open access: yes, 2006
Machining is a material removal process that alters the dynamic properties during machining operations. The peripheral milling of a thin-walled structure generates vibration of the workpiece and this influences the quality of the machined surface.
