The Stability of Milling of Thin-walled Workpiece
(0) In order to control the cutting chatter in machining of thin-walled workpieces, the dynamic milling model of thin-walled workpieces is analyzed and built based on the analysis of degrees in two perpendicular directions of tool-workpiece system. In high speed milling of 2A12 aluminum alloy, the compensation method based on the modification of inertia effect was proposed and accurate cutting force coefficients were obtained. Modal parameters of tool-workpiece system were acquired via modal analysis tests. Hie stable lobe for high speed milling of 2A12 aluminum alloy thin-walled workpieces and limit cutting axial-depth at different cutting radial-depth were obtained. The results were verified with cutting tests. The method can be used in milling of thin-walled workpieces to select cutting parameters properly. AD these work lay a reliable foundation to the further studies on the cutting chatter rules of thin-walled workpieces.
