3D-Model-Based Integrated Capp System for Aircraft Structural Parts

The Fabrication of aircraft structural parts is the bottleneck for manufacturing the modern aircrafts due to their structure complexity and technical difficulty. In order to improve the capability to fabricate the complicated aircraft structural parts and the efficiency of technical preparation, and also to accumulate and share the domain knowledge of manufacturing process, and reuse the 3D product model in the procedure of manufacturing, this paper introduced a kind of 3D-model-based integrated CAPP system by using digital and intelligent manufacturing technology, with which some problems above can be solved when manufacturing aircraft structural part. Some key technologies related to 3DCAPP system, such as the modelling technology of 3D manufacturing feature, the feature-based typical processing template, the procedure of knowledge-based process decision-making and visual manufacturing process on-machine application and so on, are introduced in this paper in details.
