  2. 6. Numerical Modelling and Analysis of Orthogonal Metal Cutting

    Author : Mathias Agmell; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal Cutting; Finite Element Method; Deformation Zones; Sub-surface Deformation; Tool Stress; Inverse Analysis; Kalman Filter; Minimum Chip Thickness;

    Abstract : Most components in use in our society have undergone a machining process at some stage within its manufacturing cycle. As a result, the economics of the machining process plays an important role in the manufacturing costs. READ MORE

  4. 7. 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.

  5. 8. Simulation on intermittent metal cutting

    Author : Per Wallén; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

  6. 9. Numerical investigation on the formation mechanism of residual stress in metal cutting

    Author : Yang Liu; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Residual stress; FEM; ; Metal cutting; Thermal-mechanical load; Plastic deformation;

    Abstract : Residual stress can be introduced unintentionally into the workpiece with various magnitudes and distributions through all manufacturing processes. These stresses have a significant effect upon the performance of the final component. READ MORE

  7. 10. Effect of shear cutting on metal fatigue

    Author : David Gustafsson; Erik Olsson; Jörgen Kajberg; Pär Jonsén; Henrik Sieurin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Punching; Trimming; Shear cutting; Fatigue; HCF; Residual stresses; Hållfasthetslära; Solid Mechanics;

    Abstract : Lightweighting of automotive and heavy-duty vehicle components is an important task that does not need any further motivation or background. It can be read in a large part of the technical papers in the field. A common approach for finding lighter solutions is to increase the material grade while decreasing the material thickness.
