摘要：
The main research object of this paper is the milling deformation of titanium alloy thin-walled parts, taking titanium alloy thin-walled blades as an example. Based on the theory of elastic plastic mechanics and the finite element method, the finite element model of the deformation caused by the cutting force of the blade machining is established. The blade deformation is analyzed by applying a cutting force to the machined area of the blade. Then based on the cutting force-deformation correlation, the static stiffness model of the machining area is established. According to the established local stiffness model of the workpiece, the deformation of the workpiece is calculated and predicted, and the threshold of the cutting force is obtained according to the analysis. This research can be used as a reference for improving the precision of CNC machining and improving production efficiency in manufacturing.
