In the aerospace field, the structural design of high-speed aircraft has high requirements for structural weight and surface protection performance. To ensure accuracy, grinding processing is usually necessary. However, manual grinding relies on experience and the working environment is harsh. Industrial robots, with their high applicability, strong flexibility, low cost and easy programming, not only improve production efficiency and product quality, but also reduce labor costs and labor intensity. ity. The latest research progress of robot grinding technology for thin-walled and complex structure coatings is reviewed, with a focus on grinding path planning, force-position hybrid control technology, and their collaborative methods. Polishing path planning includes path generation and discretization methods, such as traditional algorithms like the equal parameter line method and the equal residual height method, as well as intelligent optimization methods. For the force-position hybrid control technology, the aspects such as control methods, control strategies and control devices are discussed. Collaborative methods of force-position hybrid control and path planning are also explored, including data sharing mechanisms, joint optimization algorithms, and model predictive control. For the force-position hybrid control technology, aspects such as control methods, control strategies, and control devices are discussed.
