Chatter stability prediction in four-axis milling of aero-engine casings with bull-nose end mill

(in lingua inglese)

A 3D chatter stability model for bull-nose end milling of aeroengine casings is developed in this paper. And the 3D model can be simplified to a 1D model in surface normal direction considering only the dominant mode of the workpiece. The model is extended to four-axis machining by adding the effects of the lead angle in the milling process. The tool-workpiece engagement region is determined by using a slice-based method and divided along the toolaxis direction into several disks. And the total stability lobe diagram for the process system is obtained by an iterative algorithm.
