  2. 16. The effect of workpiece material and its microstructure on tool wear in metal cutting

    Author : Philipp Hoier; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scanning electron microscopy; Superalloy; Cutting tool; Wear; Cemented carbide; Steel; Machining;

    Abstract : The aim of the present work is to promote the basic understanding of how the workpiece material and its microstructure affect the tool wear during metal cutting. To isolate the effect of the workpiece material, the tool material (uncoated cemented carbide) was kept constant while the workpiece was varied. READ MORE

  4. 17. Adhesive wear testing and modelling of tool steels sliding against sheet metals

    Author : Fredrik W. Lindvall; Jens Bergström; Pavel Krakhmalev; Mikael Olsson; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive wear; Materialteknik; Materials Engineering;

    Abstract : Sheet metal forming is a manufacturing method used because of its versatility. Sheets are plastically deformed by a tool to create a product. A tool is expected to last for several 100,000 forming operations and efforts are made to optimize the tools. A common type of wear referred to as galling is the adhesion of sheet material to the tools. READ MORE

  5. 18. Modelling the offset lithographic printing process

    Author : Cristofer Englund; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neural networks; Self-organizing map; Data mining; Outlier detection; Leverages; Committee; Adaptive modelling; Image analysis; Bildanalys;

    Abstract : A concept for data management and adaptive modelling of the offset lithographic printing process is proposed. Artificial neural networks built from historical process data are used to model the offset printing process aiming to develop tools for online ink flow control. READ MORE

  6. 19. 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

  7. 20. Modelling of wear and galling in press hardening simulations

    Author : Liang Deng; Mats Oldenburg; Karl Nielsen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Implementation of press hardened parts in automobile responses to the requirement of reduced carbon dioxide emission because the press hardened part has very high ratio of strength to weight. Furthermore, ultra high-strength steels (press hardened parts) increases the vehicle safety. READ MORE
