    Sammanfattning : The objective of this thesis is to develop a simulation tool and a method by which robot trajectories, temperature histories, residual stresses and distortion can be analysed and optimized off-line. This was performed by integrating robot simulation software with finite element analysis software. LÄS MER

  3. 3. Robotic Friction Stir Welding for Flexible Production

    Detta är en avhandling från Lund : Lund University

    Författare :Jeroen De Backer; Högskolan Väst.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell arbetsvetenskap; Industrial engineering; Mechatronics; Mekatronik; Friction Stir Welding; Automation; Robotics; Aluminium; Lightweight design;

    Sammanfattning : Friction Stir Welding eller ”friktionsomrörningssvetsning” är en svetsprocess som kräver ett roterande verktyg som genom friktionsvärme får materialet att mjukna. Verktyget blandar runt det plastiska materialet mekaniskt och skapar en fog av hög kvalité. LÄS MER

  4. 4. Instrumentation and estimation for high temperature control

    Detta är en avhandling från Göteborg : Chalmers Reproservice

    Författare :Petter Hagqvist; Högskolan Väst.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing and materials engineering; Produktions- och materialteknik; Physics; Fysik; Additive Manufacturing; Automation; Emissivity; Emissivity Compensated Spectral Pyrometry; Laser Metal Wire Deposition; Metal Deposition; Pyrometry; Resistance Feedback Control; Thermometry; Varying Emissivity;

    Sammanfattning : Within a variety of industrially relevant high temperature production processes such as welding, heat treatment and metal deposition, the quality of the manufactured component is largely affected by how well parameters can be controlled during processing. These parameters might be, in the case of metal deposition, power input, material feed, or a parameter which is common for all of the aforementioned processes: material temperature. LÄS MER
