Master's Thesis from the year 2002 in the subject Computer Science - Applied, grade: 2,3 (B), Technical University of Berlin (Institute for Machine Tools and Factory Management (IWF)), 59 entries in the bibliography, language: English, abstract: Integration of a CAx (Computer Aided x) system throughout the product lifecycle and among different enterprises is a major issue for industrialcompetitiveness and collaboration. One of the main successful factors for CAxsystem integration is efficient methodology for EPDE (Engineering ProductData Exchange). Data exchange is the totality of establishing the approach forand the successful achievement of the transfer of data between two distinctCAx systems.Problem Statement:- Why does an exchanged CAD (Computer Aided Design) model lose somemodelling properties? – Especially losses such as model tree (designintent) and features.- What reasons influence that phenomenon?- How can these losses be minimized?2. Review state of the art of exchange strategiesThe review of exchange strategies is focused on which existing approachesare in use today, which capabilities are supported by them, which deficienciesthey have, an understanding of state of the art is a precondition for beginningto deal with of the problem statement.3. Analysis of modelling capabilities regarding featuremodelling and structure representationThe analysis begins with a short review of existing feature modellingtechniques, which will build up a framework for the analysis process. ThreeCAD systems are analysed – Pro/Engineering, I-DEAS and UniGraphics.Typical models, with the frequently occurring features, are revieweddepending on the feature modelling method and structural representation.4. Needs-identificationThe results of the analysis of modelling capabilities lead to the improvementof new methods and techniques. This defines the essential basis for thebuilding of a concept framework.5. Requirement definitions- How can the model-tree to be exchanged?- How will the exchanged model-tree act?6. Outline of the thesisThe material is organized in three major sections. The first one, the state ofthe art, examines the fundamentals of exchange approaches, the currentstate of scientific and commercial exchange approaches and further relatedtechnologies.The second one, presents the current state of feature modelling techniquesand analyses of three commercial CAD systems according to featuremodelling capabilities and structural representation.The next section, the concept framework, designs a concept framework fittingthe requirement definitions.
