  1. 16. Aspects of Flexographic Print Quality and Relationship to some Printing Parameters

    Författare :Johanna Johnson; Lars Järnström; Magnus Lestelius; Peter Rättö; Erik Blohm; Jouko Peltonen; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexography; Print Quality; Liner; Board; Newsprint; Water-borne ink; Dynamic Pressure; Plate Properties; Wetting; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : Flexographic printing is a common printing method in the packaging field. The printing method is characterized primarily by the flexible printing plate and the low viscosity inks which make it suitable for use on almost any substrate. LÄS MER

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

    Författare :Julia Madrid; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 18. 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

  5. 19. Quality of Structural Timber - End-User Requirements and Performance Control

    Författare :Mikael Perstorper; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The performance and quality of structural timber products cannot solely be defined by mechanical properties. It is the totality of features of a product that determines its ability to satisfy the customer. This thesis covers three aspects within the context of structural timber quality: Quality requirements for structural timber products. LÄS MER

  7. 20. Planning Robotic Assembly Sequences

    Författare :Domenico Spensieri; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; robot routing and scheduling; path planning; Assembly planning; geometrical variation; cycle time optimization;

    Sammanfattning : In the automotive industry, short ramp up times and high product quality drive the development toward state-of-the-art solutions both in the research and industrial perspective. In addition to that, a sustainable industry requires optimized equipment utilization, in terms of materials used and consumed energy. LÄS MER
