  3. 2. Towards Surface Engineering

    Författare :Bengt-Göran Rosen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The purpose of this dissertation is to explore a route towards surface engineering both by the introduction of a conceptual framework called Interactive Surface Modelling (ISM) and by the actual application of the concept on two functional surfaces of importance to the automotive industry: cylinder liners for engines and leather imitation surfaces for the interior of cars. The results are presented in six separate but related papers concerning the construction of the ISM system shell and the use of modern technology to explore and represent the functional knowledge relevant to the specification of surface properties.

    Författare :Martin Helgoson; John Corbett; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The thesis concludes the research work aimed at quality monitoring of parts associated with double twisted surfaces. Different CAD/CAM-based approaches and parameters for quality evaluation have been proposed. LÄS MER

  5. 4. Cut isogeometric methods on trimmed multipatch surfaces

    Författare :Tobias Jonsson; Mats G. Larson; Karl Larsson; Johan Hoffman; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cut finite element method; isogeometric analysis; Nitsche s method; a priori error estimation; parametric geometry; interface problem; surface CAD;

    Sammanfattning : Partial differential equations (PDE) on surfaces appear in a variety of applications, such as image processing, modeling of lubrication, fluid flows, diffusion, and transport of surfactants.  In some applications, surfaces are drawn and modeled by using CAD software, giving a very precise patchwise parametric description of the surface.

  7. 5. An industrial robot as carrier of a laser profile scanner : motion control, data capturing and path planning

    Författare :Sören Larsson; Johan Kjellander; Wolfgang H. Koch; Örebro universitet; []
    Nyckelord :Geometric reverse engineering; Laser scanning; Industrial robot; Path planning; CAD; 3D measurement systems; Mechanical engineering; Maskinteknik; TECHNOLOGY; TEKNIKVETENSKAP; Mechanical Engineering; Maskinteknik;

    Sammanfattning : Geometric Reverse Engineering (RE) is concerned with the problem of creating CAD-models of real objects by measuring point data from their surfaces. In the aim of creating a fully automatic RE system there is a need to automate also the measuring process. LÄS MER
