Abstract

Chatter prediction for 2 degree of freedom (DOF) milling model is presented. The workpiece is assumed to be flexible and the tool to be stiff. Non-linear cutting force model is used, and the linearized equation of motion is derived. Stability charts are constructed for different stiffness values in the directions x and y. The charts for the 1 DOF models associated with the x and the y directions are also given. It is shown that the 2-DOF case can not be given via the pure overlaying of the charts of the two single DOF cases.
