Abstract: Industrial robot machining technology is widespread used in drilling, riveting, milling, grinding and other processes in aerospace, high-speed train, shipbuilding, and other high-end manufacturing industries. However, the low positioning accuracy of industrial robot has always limited its development and further application in high-precision manufacturing. Therefore, the research on robot accuracy compensation technology is important to improve the positioning accuracy of robot. In this paper, the research status of accuracy compensation technology of industrial robot is summarized, the source of positioning error of robot is analyzed, and the current research methods and application progress in improving robot positioning accuracy are organized. The trend of improving positioning accuracy of robot in the future is summed up, which can provide guidance for the further application of industrial robot in manufacturing industry.

Key words: industrial robot, accuracy compensation, robot machining, error analysis, aerospace manufacturing
