  4. 2. Improvement of the tissue manufacturing process

    Author : Jonna Boudreau; Bengt Järrehult; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Abstract : The creping process and the conditions on the Yankee cylinder are the key factors in the production process. They need to be kept under good control in order to maintain a high and uniform quality. READ MORE

  5. 3. Simulation of manufacturing sequences for verification of product properties

    Author : Mats Werke; Torsten Kjellberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing engineering and work sciences; Produktion och arbetsvetenskap;

    Abstract : The manufacturing sequence may to a large extent influence properties like residual stresses and hardness and, as a consequence, the fatigue life and shape accuracy of a component. By simulating the manufacturing sequence and extract important accumulated data, the possibilities of early analysis of a design concept of a component and optimisation of the complete manufacturing sequence may increase.

  6. 4. Information management for the factory planning process

    Author : Danfang Chen; Torsten Kjellberg; Pär Mårtensson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Factory design; information management; models; digital factory; layout design; factory design; Manufacturing engineering; Produktionsteknik;

    Abstract : This thesis is based on the present needs for the factory planning support, of which the most important ones are: • A structured reuse of knowledge and support for industries. Because today the industry handbook in factory planning is not satisfying enough to support this complex process. READ MORE

  7. 5. On Peritectic Reactions and Transformations and Hot Forming of Cast Structures

    Author : Hani Nassar; Hasse Fredriksson; Rian Dippenaar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; peritectic reactions; massive transformations; thermal analysis; Fe-base alloys; steels; growth irregularities; hot forming; compression testing; flow stress; grain size.; Metallurgical manufacturing engineering; Metallurgisk produktionsteknik; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : This thesis deals with peritectic reactions and transformations that occur during the solidification of many alloys. Peritectics are believed to be a major cause of crack-formation in many steels, thus, good knowledge of the mechanisms by which these phenomena occur is essential for preventing such defects.
