  1. 21. Visual Robustness: Effects of Variation on Product Appearance and Perceived Quality

    Författare :Karin Nordvall; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; craftsmanship; robust design; perceived quality; optical quality; visual quality appearance; visual robustness; geometrical variation and non-nominal visualization; industrial design;

    Sammanfattning : For consumer products where the product appearance plays an important role in meeting expectations, the visible effects of manufacturing variation can have a negative influence on the product experience. A prerequisite in mass production is that no manufactured units are exactly identical, as a result of variation. LÄS MER

  3. 22. Cost-effective Sheet Metal Assembly by Automatic Path Planning and Line Balancing, Integrated with Dimensional Variation Analysis

    Författare :Johan Segeborn; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robot coordination; sheet metal assembly; dimensional variation; robot motion planning; Equipment utilization; traveling salesman problems and robust design.; load balancing;

    Sammanfattning : Automobiles are an integral part of modern society and its way of life. In addition, automotive manufacturers are important institutions in society, summing the work of a vast array of sub suppliers, employing many. The margins are however moderate and competition is fierce. LÄS MER

  4. 23. Towards improvement of geometrical quality for manual assembly parts

    Författare :Mikael Rosenqvist; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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.

  5. 24. Computational Methods for Deformable 1D Objects in Virtual Product Realization

    Författare :Tomas Hermansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assembly verification; variation simulation; robust design; path planning; Cosserat rod theory; deformable 1D objects; automatic routing;

    Sammanfattning : In industry today, virtual design tools are used in the realization of a new product. As changes in the design and planning concepts are extremely costly in the later verification and production phases, much can be gained if a product design can be optimized and verified with respect to the assembly process with simulation tools as early as possible.

  7. 25. Individualizing assembly processes for geometric quality improvement

    Författare :Abolfazl Rezaei Aderiani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Selective Assembly; Individualization of production; Locator Adjustments; sheet metal assembly processes; Variation Simulations; Geometry Assurance;

    Sammanfattning : Dimensional deviations are a consequence of the mass production of parts. These deviations can be controlled by tightening production tolerances. However, this solution is not always desired because it usually increases production costs. LÄS MER
