  2. 11. Machinability Testing of Materials in Metal Cutting with Focus on Compacted Graphite Iron and Cutting Fluids

    Author : Varun Nayyar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UTS.; Boring; Drilling; Cutting Fluid; Turning; Milling; Force; Wear; Force; Torque; Compressed air; CGI; Hardness; Tool Life; Material Properties; Chip Microstructure; Tapping;

    Abstract : Due to the stringent demands for lower emission from trucks require better mechanical properties of the material to be used in the engines. Better efficiency necessitates higher peak pressure in the engines and for traditionally used material, Flake Graphite Iron (FGI), the mechanical properties starts to reach the limit of what the material can withstand.

  4. 12. Performance Testing of Cutting Fluids and Tool Holders in Metal Cutting

    Author : Varun Nayyar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chip Microstructure; Torque; Drilling; Compressed air; Turning; Tool-holding; Force.; Tapping; Keyword: Cutting Fluid;

    Abstract : ABSTRACTThe metal cutting industry has evolved over the last century to the point where an increasing range and complexity of tool holding systems and cutting fluids are available for metal machining in the market. Most of the companies report their cutting fluid cost to be between 7 -17 % of the manufacturing cost. READ MORE

    Abstract : Behandling med käkbensförankrade tandimplantat är en vanlig metod för att ersätta förlorade tänder hos helt och partiellt tandlösa patienter. Trots att implantatbehandling uppvisar en långsiktigt hög lyckande- och överlevnadsfrekvens (90–95% efter 10 år) så förekommer implantatförluster och marginal benförlust kring implantaten under det första året efter insättning och/eller belastning, vilket kan försämra det estetiska resultatet.

  7. 15. Torque based estimation of diesel engine combustion phasing

    Author : Mikael Thor; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion modeling; Diesel engines; Crankshaft torque measurements; Combustion phasing control; Combustion phasing estimation;

    Abstract : Demands on increased efficiency and reduced emission levels introduce new challenges for the design of modern diesel engines. In order to fulfill these demands, diesel engines of today are becoming more and more complex. This escalating complexity not only applies to the engine itself, but also to its control system.
