摘要
研究基于Pro/Engineer软件环境的Top-Down设计技术在数控铣床虚拟装配与维修系统设计中的应用。在概念设计所确定产品的布局与结构模型基础上,根据Top-Down设计方法构建整个机床的二维参数化布局(Layout)。通过建立骨架模型(Skeleton)的方法将其具体化和3D化,并以此为基础完成包括整个产品装配结构的产品模型。进行基于产品模型的各子系统的分解及各子系统的设计细化。经各子系统协调并行设计,最终完成整个产品设计。
It applies top - down design technology based on Pro/Engineer software to the virtual assembly ＆ repair system of NC milling. On the foundation of layout and construction model confirmed with conception design, it constructs two dimension parameter layout of machine tools, and creats threedimension project by constructing skeleton model. The manufacture model includs assembly structure of whole product. Based on the product model, it develops decompose and continue design of each subsystem. The design of whole product is finished by concurrent design of each subsystem in harmony.
