Milling of thin-walled workpiece is the most widely used process in aerospace industries. Due to the low rigidity of the milling system

chatter often occurs

which will decrease the machining efficiency and product quality. Thus

it is greatly significant for high performance milling to study the dynamic modelling technics on milling process of aerospace thin-walled workpiece and further to select the process and tool geometry parameters. In this paper

dynamic modelling technics on milling process of aerospace thin-walled workpiece including dynamic modelling the tool-spindle system

the in-process thin-walled workpiece and milling processes are introduced.
