  1. 1. Tool steel for tool holder applications : microstructure and mechanical properties

    Författare :Anna Medvedeva; Jens Bergström; Birger Karlsson; Karlstads universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; tool steel; tool holder; microstructure; mechanical properties; machinability; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Large improvements in cutting tool design and technology, including the application of advanced surface engineering treatments on the cemented carbide insert, have been achieved in the last decades to enhance tool performance. However, the problem of improving the tool body material is not adequately studied. LÄS MER

  3. 2. Polishability of tool steels : Characterisation of high gloss polished tool steels

    Författare :Sabina Rebeggiani; Olaf Dambon; Högskolan i Halmstad; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tool steels; surface characterisation; polishability; 3D parameters; high gloss polishing; Surface engineering; Ytbehandlingsteknik;

    Sammanfattning : The manufacturing of plastic components, like a majority of other mass produced discrete parts, require well designed dies and moulds. Complex geometries and increasing demands on final surface appearance, which is strongly connected to the quality impression, are pushing for high demands on mould-makers and polishers as well as steel producers.

  4. 3. On Polishability of Tool Steels

    Författare :Sabina Rebeggiani; Bengt-Göran Rosén; Liam Blunt; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tool steels; surface characterisation; surface texture parameters; polishability; high gloss polishing; injection moulding; tool steels;

    Sammanfattning : One of the world’s fastest growing industries is the plastic industry. Today’s ever increasing demands of high quality products, shorter lead times and reduced costs push development and research forwards. LÄS MER

  5. 4. Performance of advanced tool steels for cutting tool bodies

    Författare :Anna Medvedeva; Jens Bergström; Pavel Krakhmalev; Staffan Gunnarsson; Volker Schulze; Karlstads universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; tool steel; cutting tool body; fatigue strength; stress relaxation; machinability; high-temperature properties; microstructure; Materials science; Teknisk materialvetenskap; Materialteknik; Materials Engineering;

    Sammanfattning : Performance of indexable insert cutting tools is not only about the performance of cutting inserts. It is also about the cutting tool body, which has to provide a secure and accurate insert positioning as well as its quick and easy handling under severe working conditions. LÄS MER

  7. 5. Machinability variations in Alloy 718 —With focus on machining of turbine components

    Författare :Pajazit Avdovic; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polar diagram; flank wear; ceramic tool; variation in material; tool wear; tool life; machinability; Inconel; Alloy 718; Machining; notch wear;

    Sammanfattning : In gas turbine engine, nickel base alloy, such as Alloy 718, accounts for almost half of the total material requirement. Nickel-base superalloys are used for gas turbine components mainly because of their outstanding strength and resistance to oxidation at high temperatures (> 550°C). LÄS MER
