During the corner machining process of 5-axis flank milling, the sharp change of tool path and tool orientation may lead to a dramatic increase of the milling force and tool vibration, which gravely impacts the machining quality. In order to address this issue, a 5-axis flank milling tool path generation method for corners by considering the dynamic characteristics of machine tool is presented in this paper. To be specific, firstly, the allowance information model of corner is built according to the part model and roughing information. Secondly, the tool trajectory based on clothoid curve and milling force constraint is optimized. And then, the tool orientation based on tool trajectories is optimized. Finally, the 5-axis flank milling tool path is generated by considering the dynamic characteristics of machine tool and the milling force constraint. The remaining materials of corner can be removed uniformly using the proposed tool path, and the curvature of the tool path is continuous. Simulation results show that the machined surface of corner is smooth, and the proposed tool path is suitable for corner machining.
