Abstract

Thin-walled elements are widely used in aerospace engines, such as blisk, casing, blade etc. There are significant vibrations while machining because of the small thickness and the poor rigidity of thin-walled workpieces which will lead to low surface machining quality, low machining efficiency and even worse the huge damage to the workpieces and the tools. Nevertheless, the vibration during milling does not happen frequently, as it is closely related to the position of the workpiece structure and the machining parameters. The stiffness of the workpiece varies due to the changing of cutting position. Therefore, vibration only appears in some positions when milling thin-walled workpieces. This paper mainly focus on monitoring the machining process in order to analyze the vibration and the position where it occurs. Moreover, with confirming the vibrated position and analyzing the reason of vibration, the paper provides a valid reference to the machining vibration controlling, the quality and effectiveness of workpiece surface.
