基于模型定义的飞机结构件三维工艺规程卡片设计

摘要

文中提出了一种基于模型定义技术的三维工艺规程卡片设计方法，首先模型定义技术生成了飞机结构件三维零件模型，再通过CAA二次开发接口提取出零件的非几何信息，然后对飞机结构件进行工艺路线及机床工序选择的确定，逐步生成工序模型，将所设计的工艺信息体现在工序卡片中，完成对飞机结构件的三维工艺规程卡片设计，最后利用CATIA软件平台以某一飞机结构件为例完成三维工艺卡片设计，验证方法的可行性。%This paper proposes a 3D process planning based on the model definition card design method. Based on the model definition technology ,a plane structure of 3D part model is generated ,and CAA secondary development interface is used to extract the geometry information of the parts. The aircraft structure craft route and the machine tool process are selected to generate process model. The designed process information is embodied in the process card. The three-dimensional process of aircraft structure discipline card design is completed. CATIA software platform is used to complete 3D process card design for a plane component structure. The method is proved to be feasible.
