Since the traditional tube bending method can＇t meet the timing demand of aviation technology,a tube digital manufacturing method was put forward. Based on the requirement analyses of digital manufacturing,a functional model and the integrated framework of tube digital manufactur- ing were proposed, the critical technologies were studied, such as knowledge based process planning, quality forecasting based on numerical modeling and simulation,fast modeling and simulation of tube bending processes. According to the framework,a tube manufacturing system integrated with process design, quality forecasting and tube bending simulation for bending processes was developed. The sys- tem was applied to a few products in one aerospace factory and the application effect is distinct.
