To manufacture the aircraft frame and rib parts rapidly and precisely, the approach of intelligent manufacturing technology development is proposed from the viewpoints of knowledge base and manufacturing model, and the intelligent manufacturing flow is established. The scheme from technology analysis, implementation to application is designed according to the application target. The technology has been applied in AVIC corporations of Hongdu, Shenyang and Chengdu. The test result shows that the forming accuracy of outer shape, flange angle and height is improved significantly and precise forming is achieved. The technology can be further applied in the future.
