  1. 1. Tooling and processing for efficient and high tolerance prepreg composite manufacturing

    Författare :Tommy Grankäll; Malin Åkermo; Per Hallander; Simon Bickerton; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tooling; Composite Manufacturing; Mould; Cure tool; Hot-forming; Compensation; Moisture; Shape distortion; Flyg- och rymdteknik; Aerospace Engineering;

    Sammanfattning : Composite use is normally motivated in aircraft design by improved weight-specific mechanical properties as compared to metals. However, fatigue and dielectric properties may also be critical for material selection. LÄS MER

  3. 2. Affordable reconfigurable assembly tooling : an aircraft development and manufacturing perspective

    Författare :Henrik Kihlman; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Industry has changed in recent years. Increased globalization has led to a situation where few manufacturers build their own complete products "in-house". This situation is no different in the aerospace industry. In fact, aircraft manufacturers who build their complete aircraft in­ house are uncommon today. LÄS MER

  4. 3. 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.

  5. 4. Friction in threaded fasteners : Influence of materials and tooling

    Författare :Mayank Kumar; Sergei Glavatskih; Erik Persson; Ellen Bergseth; Ian Sherrington; Robert Wood; KTH; []
    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; Friction; Coating; Surface topography; Tightening speed; Additive manufacturing; Tightening condition; Assembly tool; Material; Friktion; Ytbehandling; Yttopografi; Åtdragningshastighet; Additiv tillverkning; Åtdragningsförhållanden; Monteringsverktyg; Material; Machine Design; Maskinkonstruktion;

    Sammanfattning : Threaded fasteners represent the most common type of machine element, with a unique function that facilitates ease of assembly and disassembly. This ease of disassembly allows machine parts to be reused, refurbished, and recycled. LÄS MER

  7. 5. Theoretical and experimental study of tooling systems : passive control of machining vibration

    Författare :Lorenzo Daghini; Cornel Mihai Nicolescu; Tomas Beno; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial engineering and economy; Industriell teknik och ekonomi;

    Sammanfattning : Vibration control has been and still remains a subject of primary importance in modern manufacturing industry. To be able to remove high volumes of material in shorter time as well as to be able to get the right quality of the parts at the first time are goals that many shops would like to achieve. LÄS MER
