Effect of Postures and Cutting Process on Robot Milling Performance and Surface Quality

The application of industrial robots in machining fields is of great significance to the integral machining of large complex structures. However, subject to the structural rigidity, it can not become the mainstream means to replace the traditional machine tool processing. In order to study the machining performance of the robot milling system and improve the machining quality, the influence of different robot postures on the machining quality was studied, and the better machining posture was selected. The influence of different process parameters on the machining performance of the robot milling system was analyzed, which provides the basis for selecting machining parameters for the robot milling system. The results show small cutting depth and high spindle speed are suitable for robot milling. Finally, by comparing the effects of milling mode and cutting direction on the robot machining system, the anisotropic characteristics of the end stiffness of the robot were revealed. The experiment results show that the machining performance of the robot milling is better when the cutting direction is along Y.
