  2. 11. Tribological aspects of aluminium extrusion dies

    Author : Thomas Björk; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Extrusion; Die; Wear; Tool; Friction; Simulation; Bearing; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : Extrusion is a common method to manufacture long products of aluminium, such as beams, rods and tubes. The aim of this thesis was to improve the material in the die bearing surface, and thereby the service life of extrusion dies through wear studies of actual dies, and experimental simulations.

  4. 12. Investigation on the Influence of Nodularity in Machining of Compacted Graphite Iron (CGI)

    Author : Gustav Grenmyr; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compacted Graphite Iron CGI ; cutting forces; wear mechanisms; tool wear; nodularity; tool temperature; cutting temperature;

    Abstract : Stringency of environmental legislation on emission rates and increasing vehicle performance requirements are pushing the automotive and heavy truck industries to find new solutions for their diesel engines. Two potential opportunities to address these challenges involve increased combustion pressure to obtain more efficient combustion or reducing the weight of the engine. READ MORE

  5. 13. Dry wear of tool steels

    Author : Sture Hogmark; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : .... READ MORE

  6. 14. Microstructure and Properties of Additively Manufactured Tool Steels for Hot Stamping

    Author : Miwen Yuan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tool Steels; Wear; Hot stamping; Additive Manufacturing; Softening Resistance;

    Abstract : Hot work tool steels are commonly used to produce dies for hot stamping, where the steels are exposed to cyclic thermal and mechanical loads. There is a constant demand to improve the lifetime of the dies. Additive manufacturing (AM) provides new solutions for tool design. READ MORE

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

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

    Abstract : 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. READ MORE
