Industrial robots can be applied in the machining work instead of CNC machine tools, which can be called machining robots. In the fields of aerospace, shipbuilding, high-speed rail train, machining robots can complete the cutting task with the advantages of large operating range, small installation space, high integration, good economic benefits and flexibility good economic benefits and flexibility. However, the stiffness of the machining robot is weaker than the CNC machine tools. Therefore, the absolute position accuracy of machining robots is lower than CNC machine tool, too. The key technology of the application of the machining robot is to improve the stiffness and the absolute position accuracy in the cutting process. The methods of improving the kinematic errors of the machining robot by optimizing the gesture were analyzed in this paper. This analysis can support a foundation and reference for improving the accuracy of the machining robot by optimizing the posture.
