  1. 1. Information Management for Cutting Tools : Information Models and Ontologies

    Författare :Olof Nyqvist; Torsten Kjellberg; Fumihiko Kimura; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Production Engineering; Cutting Tools; Information Models; International Standards; Reference Data; Ontologies; Information technology; Informationsteknologi;

    Sammanfattning : There is an increasing demand for the exchange of important product and manufacturing information in a computer interpretable way. Large manufacturing companies are dependent on having access to the necessary information electronically. LÄS MER

  3. 2. Workpiece steels protecting cutting tools from wear : A study of the effects of alloying elements on material transfer and coating damage mechanisms

    Författare :Toshiharu Aiso; Staffan Jacobson; Urban Wiklund; Staffan Söderberg; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal cutting; Steel; Cutting tools; Transfer; Coating; Sliding; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : The vision of this thesis is to improve the machinability of workpiece steels. Workpiece material frequently transfers to the cutting tools during machining, and the transfer layers then forming on the tools may give both good and bad effects on machining performance and tool life.

  4. 3. On wear of wood-cutting tools : Tool materials, wear mechanisms and modelling

    Författare :Johan Nordström; []
    Nyckelord :Tool material; Wood cutting; Wear; Modelling;

    Sammanfattning : Bandsaw blades are commonly used in the sawmill industry for timber cutting. The saw teeth are gradually worn during cutting and will finally cause unacceptable surface roughness and dimensional deviations on the sawn wood product. Maintenance by re-sharpening of the saw teeth is therefore necessary after a certain time of sawing. LÄS MER

  5. 4. Tribology at the Cutting Edge : A Study of Material Transfer and Damage Mechanisms in Metal Cutting

    Författare :Julia Lundberg Gerth; Urban Wiklund; Uppsala universitet; []
    Nyckelord :Tribology; Metal cutting; Gear hobbing; Wear; Coating; Residual stress; Material transfer; Steel; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : The vision of this thesis is to improve the metal cutting process, with emphasis on the cutting tool, to enable stable and economical industrial production while using expensive tools such as hobs. The aim is to increase the tribological understanding of the mechanisms operating at a cutting edge and of how these can be controlled using different tool parameters. LÄS MER

  7. 5. Tool Life and Cutting Data Modelling in Metal Cutting : Testing, Modelling and Cost Performance

    Författare :Daniel Johansson; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metal cutting; tool life; tool wear; cutting data; process cost; Colding model; part cost;

    Sammanfattning : One of the most important production processes in industry is metal cutting. If a product is not a machined metal part, it is likely that the mould, die and tools used to produce the product or parts of the product are machined. LÄS MER
