Stability Limits of High-Speed Milling of Thin-Walled Workpiece

Abstract:

In order to control chatter in machining of thin-walled workpieces, the dynamic model of milling od thin-walled workpiece is analyzed based on considering the flexibility of the workpiece and the machine. In high speed milling of 2A12 aluminum alloy, the compensation method based on the modification of inertia effect is proposed and accurate cutting force coefficients are obtained. The machining system is divided into “spindle-cutter” and “workpiece-fixture” two subsystems and the modal parameters of two subsystems are acquired via modal analysis experiments. A method for obtaining the stability lobes is presented by considering the relative movement of both subsystems. Finally, the stability lobes for high speed milling of 2A12 thin-walled workpiece are obtained and compared between considering three kind of modal parameters. The results are verified against cutting tests.
