  1. 6. 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. 7. Styckares arbete : knivskarpt om hållbarhet

    Författare :Kjerstin Vogel; Jörgen Eklund; Roland Örtengren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ergonomics; meat cutting; knife; knife sharpening; polishing; interactive; industry intervention; sustainability; profitability; change; yield; stress; RAS; Ergonomi; styckning; kniv; knivskärpa; polering; interaktiv; branschintervention; hållbarhet; lönsamhet; förändring; utbyte; stress; RAS;

    Sammanfattning : Styckares arbete är fysiskt ansträngande och kännetecknas av att vara utpräglat manuellt där den handhållna kniven är det viktigaste verktyget. Arbetet innebär enligt arbetsskadestatistiken hög risk för arbetsrelaterade skador och sjukdomar. LÄS MER

  4. 8. 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. 9. FE-Simulation of Metal Cutting Processes

    Författare :Ahmet Semih Ertürk; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inverse identification; Machine learning; Metal cutting; Finite element method; Heat transfer; Machining;

    Sammanfattning : Machining a new component or a new material requires the selection of the cutting conditions, the tool material and the tool geometry. The selections should be also optimized for the existing components and materials to improve the quality of the produced components and reduce the cost of production. LÄS MER

  7. 10. FE-Simulation of Metal Cutting Processes

    Författare :Ahmet Semih Ertürk; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal cutting; Ductile fracture; Gradient damage; Finite element method; Turning; Machining; Inverse identification;

    Sammanfattning : This thesis deals with the finite element (FE) simulation of machining processes. Realistic simulation of metal cutting processes enables a more resource-efficient machinability assessment for a given material in terms of cutting forces, chip shape and tool wear at different ranges of cutting conditions.
