In the process of cutting titanium alloy by ball-end milling cutter, the surface quality of the workpiece is difficult to guarantee, and the cutting force is the main factor affecting the surface quality of the workpiece. Aiming at the above problems, the bionic structure is combined with the ball-end milling cutter to simulate the bionic ball-end milling cutter. Firstly, the forming process of the machined surface during the cutting process of the ball-end milling cutter is analyzed, and the effective cutting speed of the ball-end milling cutter is solved, the geometric model of equivalent cutting thickness is established. Finally, the finite element model of the bionic ball-end milling cutter was established to study the equivalent stress state of the workpiece under different bionic structure types, and the influence of bionic structure on the cutting force was analyzed. The conclusions obtained provide a theoretical basis for the selection of parameters for the preparation of bionic ball-end milling cutters.
