Feature Based

Feature-based programming is one of tendency of NC programming technology, and it is also an important portion for CAD/CAPP/CAM integration in the manufacturing enterprises. Because of selecting geometry repeatedly, random programming and bad integration during programming for the aircraft NC parts, the technology of rapid programming based on features is put forward in this paper. On the basis of features, the technology of feature recognition for aircraft NC parts and the algorithm of tool path generation based on features are integrated by taking XML as data transfer standard. With this method, the programming for aircraft NC parts can be realized quickly in the condition of CAD/CAPP/CAM integration. The system developed has been well applied to the programming for aircraft NC parts in an aircraft corporation.

Based on analyzing the existing algorithms, a novel tool path generation of 2D contour considering stock boundary is presented. Firstly the boundary points of stock are obtained by three-dimensional measuring machine. And the boundary curve is constructed by method of features identifying. The stock boundary is offset toward outside with tool diameter. An enclosed region is formed between the contour curves and the offset curves of stock boundary. The tool path is generated by form of parallel spiral by offsetting the stock boundary in the enclosed region. Finally the validity of present method is demonstrated by an example.
