摘要: |
在全三维研制模式下,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。分析了全三维研制模式下,模型应当具备四个要素才能满足制造信息的完整性。通过调研发现,没有同时满足这四要素的模型格式能够在不同CAD/CAM平台间传递,导致制造信息的传递出现障碍。因此提出基于主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,由主模型派生出轻量化模型和各类工艺模型的转换方法,并成功应用于部分型号产品的全三维研制。 |

Abstract: |
3D design model with product manufacturing information (PMI) is the major carrier of product data transformation on full 3D manufacturing mode. Integrity of PMI transformation needs four model factors. The survey results show that design model with whole four factors can’t be transformed completely between different CAD/CAM platforms. A parallel passing mode based on master model is proposed in this paper. Modeling exchange methods such as lightweight model exchange and process model exchange can be used to express the four factors perfectly at the manufacturing stage, and this method is successfully used in full 3D manufacturing of some products. |
