全三维模式下机械模型跨平台转换研究

3D mechanical model transformation on cross platform

全三维模式下,产品数据传递的主要载体是带有制造信息的三维设计模型。通过大量调研及转换测试发现,为避免在不同CAD/CAM平台之间传递出现障碍,全三维模式下机械模型应当具备4个要素才能满足制造信息的完整性。提出基于主模型(设计模型)的并行传递模式,解决了设计模型四要素在制造阶段的完整表达;并利用主模型派生出轻量化模型和各类工艺模型的转换方法,实现了产品在全三维模式下生产,为数字化设计制造打下了坚实的基础。

In the full 3 D （three dimensions） manufacturing process, the 3 D design model is the main carrier of product data to transmit the manufacturing information. Through a lot of survey and test, it is found that the 3D model should possess 4 attributes to satisfy the integrity of manufacturing information and be able to avoid the obstacles in different CAD/CAM platforms. The parallel transmission mode, using the main model （the design model） ,is proposed to solve the complete expression of four elements of the design model in the manufacturing stage;then, the main model derives lightweight model and the process planning conversion method ,which realizes the production of some products and lays a solid foundation for digital design and manufacturing.
