Abstract: Aiming at the structural design and cutting life of angle milling cutter, the mechanical properties of angle milling cutter in cutting process were studied. The angle milling cutter was designed according to the design principle and the cutting model of angle milling cutter was established in LSDYNA based on the theory of obliqueangle cutting. The influence of different cutting factors and cutter geometric angles on cutting force was studied and the correctness of the cutting model was verified by comparing with the theoretical results. On this basis, the cutting mechanical properties of milling cutter with different structural angles was studied, which provided a theoretical basis for the structural design of angle milling cutter. The results indicate that the double angle milling cutter has better cutting mechanical properties than the single angle milling cutter, but its teeth are weak, and it is easy to cause cutting edge collapse when milling at high speed, and the angle milling cutter with Rtype cutter has better cutting mechanical performance than that with sharp type. The shape of its cutter teeth can be processed into Rtype.
