| Summary: | Vertical milling is often adopted in manufacturing of complex curved surfaces such as thin-walled blades used in the aerospace, In order to improve the machining efficiency and surface quality, the contact between tool and workpiece is always increased. But the cutter structure parameter is very important for milling quality. The vertical milling process is analyzed and the mechanical model of milling is established. The main factors influencing the milling process are the spiral Angle, the diameter of the milling cutter and the number of edge of milling cutter. AdvantEdge FEM software is used for finite element simulation of milling. The finite element simulation of milling is carried out by using univariate factors. The milling force, machining deformation, stress and strain are analyzed. The results show that the stress and deformation of cutter, the stability of tool vibration and the quality of machining are effectively improved by increasing the spiral Angle, radius of milling cutter, and number of edge of milling cutter.
