  1. 1. Towards improvement of geometrical quality for manual assembly parts

    Author : Mikael Rosenqvist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calculation model; geometry system; Interview; assessment; action cost.; assembly; error; ergonomics; assembly complexity; design for assembly; robust design; complexity; manual assembly; sustainable; tolerance analysis and design; CAT; quality; failure; action cost; assembly ergonomics;

    Abstract : Geometrical variation affects all mass-produced products. This variation will lead to deviations from the nominal design of the product both in terms of aesthetical and functional properties. Geometrical variation originates either from the manufacturing of the parts or from the assembly process.

  2. 2. Design for Producibility in Fabricated Aerospace Components - A framework for predicting and controlling geometrical variation and weld quality defects during multidisciplinary design

    Author : Julia Madrid; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quality Assurance; Welding; Aerospace; Design for Producibility; Welding simulation; Variation Management; Design for Manufacturing; robust design;

    Abstract : In the aerospace industry, weight reduction has been one of the key factors in making aircraft more fuel efficient in order to satisfy environmental demands and increase competitiveness. One strategy adopted by aircraft component suppliers to reduce weight has been fabrication, in which small cast or forged parts are welded together into a final shape. READ MORE

  4. 4. EFFICIENCY OF FLEXIBLE FIXTURES: DESIGN AND CONTROL

    Author : Ilker Erdem; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control; design; fixture; assembly; manufacturing; efficiency; flexible; production;

    Abstract : The manufacturing industries have been using flexible production technologies to meet the demand for customisation. As a part of production, fixtures have remained limited to dedicated technologies, even though numerous flexible fixtures have been studied and proposed by both academia and industry. READ MORE

  5. 5. Managing Interruptions in Manufacturing : Towards a Theoretical Framework for Interruptions in Manufacturing Assembly

    Author : Ari Kolbeinsson; Dan Högberg; Peter Thorvald; Jessica Lindblom; Steve Summerskill; Högskolan i Skövde; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Interruptions; Manufacturing; Mobile Devices; Cognition; Technology; Teknik; User Centred Product Design; Användarcentrerad produktdesign;

    Abstract : The effect of interruptions from ICT systems on assembly workers in manufacturing is examined in this thesis, as is how the risks of errors, increases in assembly time, increased cognitive load and resultant stress can be mitigated, as well as ensuring that important new information is acted upon. To these ends, a literature study was conducted, followed by two studies using an experimental approach in an environment that simulated a manufacturing assembly situation, and used tasks designed to be representative of manufacturing assembly tasks.
