| Abstract | The technology of linear flow splitting to produce bifurcated sheet metal structures is researched by the collaborative research center 666 since 2005. So far the product design process is supported by 3D-CAD models on the basis of User-Defined-Features in standard 3D-CAD systems. This paper now presents a new approach for generating 3D-models of integral sheet metal design products with higher order bifurcations based on a low-level 3D-kernel. The emphasis is placed on two aspects, namely the processing of the model’s topology and geometry as well as the software implementation. First, a methodology for the generation and manipulation of the geometry and topology of the Boundary Representation (B-Rep) structure is proposed. This methodology is integrated into an algorithm-based product design approach, which enables engineers to plan and design their complete draft for bifurcated sheet metal parts in an automated, computer aided way. Further functionalities to support the subsequent manufacturing process are developed and integrated. The idea is then implemented by developing a 3D-CAD application using the B-Rep CAD-kernel Parasolid. The programming framework. NET has been chosen for the development of the software on a Windows NT platform using the object-oriented C++ and C# programming languages. The work presented here has significant implications on the quality, accurateness and efficiency of the product generation process of sheet metal products with higher order bifurcations. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
