摘要
为充分运用冲压工艺的成功实例,对基于CBR的冲压工艺设计系统中的关键技术—冲压件相似检索进行了研究。首先进行冲压件信息模型的表示;然后通过API提取冲压件的2D展开图轮廓、3D拓扑关系及特征;接着按2D展开图轮廓、3D拓扑关系、设计特征、板材4个步骤分别与数据库中的实例进行相似计算,综合结果,检索出最相似的实例。通过实验验证了该方法的有效性。
To use the successful cases of punching process-planning,the key technology of CBR punching process planning system-similarity retrieval for stamping parts is studied.Firstly set up the information model of stamping part.Then used API to extract the profile of flat pattern,3D topology relation and feature property.The closest cases are retrieved from database by integrating the results of four-step similarity retrieval,which includes flat pattern profile,topology relation,feature property and material information.The experimental results show that this approach has high effectiveness.
