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

    University dissertation from Karlstad : Karlstad University Studies

    Author : Johan Nordström; [2005]
    Keywords : Tool material; Wood cutting; Wear; Modelling;

    Abstract : 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. READ MORE

  2. 2. Simulation of Wheel and Rail Profile Evolution Wear Modelling and Validation

    University dissertation from Stockholm : KTH

    Author : Roger Enblom; KTH.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; contact; wear; wear prediction; wear model; wheel profile; rail profile; simulation vehicle-track interaction; multibody simulation; MBS; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Numerical procedures for reliable wheel and rail wearprediction are rare. Recent development of simulationtechniques and computer power together with tribologicalknowledge do however suggest computer aided wear prediction. READ MORE

  3. 3. Wear in cone crusher chambers

    University dissertation from Stockholm : KTH

    Author : Mats Lindqvist; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cone crusher; modelling; wear; rock crusher; work hardening;

    Abstract : Cone crushers are widely used in the mining and aggregates industries to reduce the size of blasted rock. A cone crusher consists of a fixed conic liner called concave and inside it a smaller moving liner called mantle. The mantle is suspended on an eccentrically rotating shaft. READ MORE

  4. 4. On Simulation of Uniform Wear and Profile Evolution in the Wheel - Rail Contact

    University dissertation from Stockholm : KTH

    Author : Roger Enblom; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel-rail contact; wear; wear prediction; wear model; wheel profile; rail; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Abstract : Numerical procedures for reliable wheel and rail wear prediction are rare. Recent development of simulation techniques and computer power together with tribological knowledge do however suggest computer aided wear prediction as possible. READ MORE

  5. 5. Influence of Microstructure in Machining of Nickel and Nickel-Iron Based Alloys

    University dissertation from Stockholm : KTH

    Author : Stefan Olovsjö; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wear mechanisms; Simulation; Tool wear; Burr; Meta-modelling; Inconel 718; Metal cutting; Superalloy; Waspaloy; Chip morphology; Notch wear; Alloy 718; JMatPro;

    Abstract : Superalloys are used in applications such as turbines, steam power plants and nuclear power systems in components that require good high temperature properties and/or corrosion resistance. They are classified as difficult-to-cut materials and hence, from a sustainable production point of view, tool wear and tool life are major factors when machining these alloys. READ MORE
