摘要
研究了钣金数控折弯加工特征信息的识别方法.可将三维CAD模型映射表示为由特征节点构成的网络图,这一方法可以对钣金零件的折弯加工工序模拟、折弯模具以及折弯夹具进行有效分析.
The paper focuses on the technique of machinable features recognition of sheet metal parts in CNC bending process. By mapping a 3D CAD model into a network graph of feature nodes the bending sequences, tool and clamp interference can be analyzed.
