6. 4. Towards Surface Engineering

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

   Abstract : 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.
