Feature Extraction and Rebuilding Algorithm Based on Key Points of Shaping Zone in Die less Drawing
Yong Min He · Jisuanji fangzhen · 2010
During the process of die less drawing,the relationship between shape of metamorphic zone and technical parameter is very complicate. The expression of shape of shaping zone is important to predicting the shape and intelligently controlling. According to the shape of metamorphic zone,a kind of feature extraction and rebuilding method was given out based on key points,which could be used in simulation system to build the model of line shape.
