Abstract:Flexible automatic machining has become the development direction of aviation manufacturing in the future. The aircraft structural parts belong to a variety of small batch production mode, the stable and efficient processing technology is difficult to obtained through iterative optimization. In order to ensure the normal operation of flexible production line, it’s necessary to solve the flexible line machining technology. According to the requirements of flexible wire machining mode, the research is carried out from the aspects of machining technology standardization, process quality control and construction of monitoring instructions. A complete set of automatic machining technology of flexible wire for aircraft structural parts is developed, which powerfully supports the efficient and stable machining of aircraft structural parts in flexible wire machining mode.
