Study on Graph Data Transform and Recognize System of Stamping Process Feature
Teng Hong-chun · Journal of Nanjing Institute of Industry Technology · 2005
To realize an automatic feature recognition system of CAD/CAPP intelligent integration of sheet metal forming, this paper presents a graph data transform and recognize system of stamping process feature that adopts IGES as the data transform by using WIN98/NT/2000. The system can read and then order *.igs data form all kinds of CAD software to conform to the requirements of designing stamping process. From shape feature and stamping process feature are in the relation of single mapping. Geometrical information and topology can be used to recognize the feature of part. By disposing data of importing IGES line,the system can realize the recognition and extraction of typical stamp features, such as primary face feature, punch feature and flange feature.
