Abstract:The mobile robot machining system is widely used in the field of aeronautical large parts assembly. Because the mobile robot machining system is separated from fixed-point operation mode for mobile machining, in actual machining process, the high-precision positioning of large parts to be machined and the machining stability of machining process must be studied and solved. Based on the review of the research on advanced mobile robot machining system at home and abroad, this paper focuses on the high-precision positioning technology of large parts in the mobile state and vibration suppression in the process of machining, in order to realize the stable machining of mobile robot, and discusses and prospects the problems to be solved and future research direction.
