摘　　要：基于零件结构特征的空间距离计算,提出了零件三维模型的唯一结构特征编码的构建方法。该编码包括了零件的外形结构特征和内部空腔结构信息,使零件在数据库中的存储和调用更加简便和准确。基于上述三维结构特征编码,本研究将铸造工艺实例中的零件信息、生产信息和工艺信息等相互关联的复杂信息体系进行“唯一性”编码,从而实现了铸造工艺数据库的快速入库和准确查询。通过对优化后的数据库的使用,能够简化铸造工艺设计流程以提高设计效率,并实现设计知识和经验再利用的最大化。Based on the spatial distance calculations of part structural features,this study proposes a method for constructing unique structural feature codes for 3D models of parts.The codes include the external structural features of the parts and the internal cavity structure information,which makes the storage and retrieval of parts in the database more convenient and accurate.Using the aforementioned 3D structural feature coding,this research uniquely codes the complex information system of part information,production information,and process information in casting process cases.This approach achieves rapid storage and accurate querying of the casting process database.Utilizing this optimized database could simplify the casting process design workflow and improve design efficiency,thereby maximizing the reuse of design knowledge and experience.
