  4. 2. Sheet metal trimming dies – characterisation methods of geometry and surface topography and the influence on wear

    Author : Per Jonsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finish milling; wear measurement; functional surface; trimming dies; scale-sensitive fractal analysis; surface roughness; polishing; surface characterisation; high strength steel; tool wear;

    Abstract : In recent years, the life cycle of car models has decreased from 7 to 5 years and the volume sizes are becoming shorter in the automotive industry. The increasing number of car models introduced to the market means that a fewer number of parts must pay the costs for the tool/die design and manufacturing. READ MORE

  5. 3. Methods for Characterisation of Pressing Die Surfaces

    Author : Johan C Berglund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finish milling; scale-sensitive fractal analysis; surface characterisation; polishing; functional correlation; : pressing dies; functional filtration; surface roughness; functional surface;

    Abstract : Design and manufacture of dies and moulds is a critical aspect of many production systems since the manufacturing and try-out of new dies and moulds often is essential in determining the lead-time and quality of a new production system. In the automotive industry, many new car models are introduced each year and for each of these models, a new set of pressing dies has to be designed and manufactured. READ MORE

  7. 5. Models of Surface Roughness with Applications in Paper Industry

    Author : Jan-Olof Johansson; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistik; actuarial mathematics; operations research; programming; Matematik; Statistics; Mathematics; estimation.; Surface roughness; parametric models; operationsanalys; programmering; aktuariematematik; Wood; pulp and paper technology; Pappers- och massateknik;

    Abstract : This thesis comprises general parametric models for surface roughness. The models can be used in several technical and natural applications but are here only applied to the micro-structure of paper. In that application, earlier models are generalized and new models introduced. READ MORE
