| 1 | Interoperability of Design Intent in Integrated Product and Process Design显示文摘Concurrent engineering is currently an overwhelming t rend in product development since it takes the down-stream product development issues and product life-cycle issues into consideration in up-front design pro cess. At this stage, evaluation, verification and validation of design concepts and design schemes is critical to the right-to-market product development. I dentification and extraction of design intent from the part digital mock-ups in different data formats and created in different CAD systems for DFX considerati on, evaluation, verification, and validation is crucial too. Traditionally, fro m manufacturing point of view, feature identification and extraction is to get t he features and feature-related information for manufacturing planning and inte gration. Presently, from the viewpoint of product development and product servi ce life cycle, design intent identification and extraction is to get all the des ign-related information for DFX consideration in early design stage, such as de sign for assembly, design for service, design for tooling, design for functional ity and design for environment etc. Therefore, how to successfully extract desi gn intent such as design and machining features and design-related information from the prototyping digital mock-ups created by different CAD systems for DFX consideration in upstream design stage is a very useful topic in integrated prod uct and process design and development. Presently, there are heterogeneous CAD systems in the market and the interoperat ion among the different CAD systems is indispensable. The interoperability of d ifferent CAD systems is by way of data exchanged technology such as STEP and IGE S. The critical weakness of this interoperation technology is that much of the design intent is lost in the interoperation process. Once the product digital m ock-ups is exchanged via data exchange technology such as IGES or STEP, the des ign intent including the dimension-driven design features and other attributes embedded in the part model are lost in the data translation process. Models rea d out of CAD systems come into other systems as featureless chunks of geometry e ntities. Obviously, the interoperation technology does not satisfy the industry need. It has been reported that this poor interoperation technology, which pro vides poor CAD models in neutral-format geometry had cost the automobile indust ry alone $1 billon per year. Fortunately, some researchers have been aware of t he criticality of this since only the United States industry spends billons of d ollars as a result of poor interoperability between computer-aided engineering software tools. In the past, product development was often done within a single company by co-located design team. In more recent years, there has been a busi ness paradigm shift in product development as the product development is being d one more often by geographically and temporally distributed design teams. There is a high level of outsourcing, not only of manufacturing but also of actual pr oduct development effort. Besides, product development across companies, and ev en within a single company, is often done within a heterogeneous software tool e nvironment. How to improve the interoperability of design intent created in het erogeneous software tool environment geographically has become a critical issue in next-generation product development system. Design intent in this research is defined as the outcome of design process. Des ign process goes from the identification of needs to satisfaction of that needs. Design intent satisfies this kind of needs. In this research, design intent i s created in a CAD system and embedded in part CAD model. The detailed design i ntent here includes design and manufacturing features and the feature-relat ed information such as feature parameters, feature relationships and some relate d characteristics such as associativity.
