  1. 1. FLEXIBLE FIXTURES - A TREATISE ON FIXTURE DESIGN AND EFFICIENCY

    Författare :Ilker Erdem; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design; reconfigurable; Flexible; fixture; efficiency; tooling;

    Sammanfattning : Even though a variety of efforts have been made in the area of flexible fixtures, the manufacturing industry still relies on dedicated fixtures with minor modular features. The main underlying reason, as these attempts have shown, is that the application of flexible fixtures has failed to yield the expected results, with the implemented technologies often leading to increased manufacturing costs when compared to dedicated fixtures.

  3. 2. EFFICIENCY OF FLEXIBLE FIXTURES: DESIGN AND CONTROL

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

    Sammanfattning : 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. LÄS MER

  4. 3. How to Reduce Geometrical Variation in Assembled Products

    Författare :Johan Carlson; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; assembled products; body-in-white BIW ; dimensional variation; geometrical variation; fixtures; fixture diagnosis; locating schemes; multivariate analysis; rigid body motion; robust design; root cause; quality; root cause;

    Sammanfattning : Vehicle problems, such as wind noise, water leakage and door closing effort are examples of quality and functionality defects that are controlled by the dimensional accuracy of the structural frame of an auto body. The aim of this thesis is towards methods for reducing geometrical variation in assembled products in the automotiv other industries. LÄS MER

  5. 4. Intention recognition in human machine collaborative systems

    Författare :Daniel Aarno; Danica Kragic; Darius Burschka; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Robotics; Human-machine collaboration; Virtual fixture; hidden Markov model; Machine learning; Artificial intelligence; Computer science; Datavetenskap;

    Sammanfattning : Robotsystem har använts flitigt under de senaste årtiondena för att skapa automationslösningar i ett flertal områden. De flesta nuvarande automationslösningarna är begränsade av att uppgifterna de kan lösa måste vara repetitiva och förutsägbara. LÄS MER

  7. 5. Variation Control in Virtual Product Realization - A Statistical Approach

    Författare :Kristina Wärmefjord; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; quality control; contact modeling; Variation simulation; welding simulation; spot welding sequence; inspection point reduction; fixture repeatability;

    Sammanfattning : All manufacturing processes are afflicted by variation, which leads to products that may not fulfill assembly, functional or esthetical requirements. The variation in the final product originates from variation in individual parts and assembly processes. LÄS MER
