摘要
在分析WCAPP数据表示和处理特点的基础上,提出了基于XML的焊接结构件产品结构层次信息模型/视图/控制结构,并阐述了模型结构表示及具体的操作方法,该模型集成了焊接接头参数数据、焊接过程主参数信息及接头焊接工艺信息,同时解决了非结构化的产品部件接头之间的拓扑关系表示,分析了该模型的结构设计及操作的一致性问题,给出了一个基于XML的产品结构树数据表示实例,分析了基于中性元文件CAD与WCAPP的图形数据的集成方法,提出基于多类型模板机制的工艺文档输出方案,保证了数据操作和工艺文档输出的规范性。
On the base of analyzing process data representing and operation properties,the structure of welding structure product hierarchy information Mode/View/Control was built.The expression and operation of model was described.Parameter data of welded joint,master parameters and information of welded joint were integrated.Non-instruct topology information of product-department-joint was described in the model.Structure of model and consistence of operation were analyzed.An example data of product structure tree was showed.Integration method of graphic data between CAD and welding computer aided process planing(WCAPP) based on litmusless meta file was analyzed.The solution of process document based on multi-type template mechanism was offered,which ensure the criterion of dada operation and outputting of process document.
