Abstract: In the milling process of titanium alloy parts, the cutting force characteristics will exert an important influence on the final machining quality of the parts. The cutting force characteristics of milling titanium alloy with ball-end milling cutter are studied. Firstly, the mathematical model of cutting force for Ti-6Al-4V milling with ball-end milling cutter is established, and the instantaneous cutting force and its variation law are obtained by compiling program. Secondly, the simulation model of Ti-6Al-4V milling with ball-end milling cutter is established by using finite element analysis software, and the stress field and temperature field in milling area are obtained. Finally, the cutting force test experiment is designed and completed, and the experimental data are analyzed by orthogonal design. The results show that the influence of cutting parameters on the average milling force is in the order of axial cutting depth, feedrate per tooth, radial cutting depth and spindle speed.
