  2. 1. On cutting tool resource management

    Author : Ana Esther Bonilla Hernández; Tomas Beno; Claes Fredriksson; Leonardo De Chiffre; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CAM programming; Cutting data; Lean; Manufacturing; Material Removal Rate; Optimization; Tool life; Tool utilization; Tool wear; Sustainability; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : The search for increased productivity and cost reduction in machining can be interpreted as desire to increase the Material Removal Rate, , and maximize the cutting tool utilization. The CNC process is complex and involves numerous constraints and parameters; ranging from tolerances to machinability. READ MORE

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

    Author : Johan Nordström; []
    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

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

    Author : Toshiharu Aiso; Staffan Jacobson; Urban Wiklund; Staffan Söderberg; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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.

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

    Author : Julia Lundberg Gerth; Urban Wiklund; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE
