  2. 11. Microstructural, Mechanical and Tribological Characterisation of CVD and PVD Coatings for Metal Cutting Applications

    Author : Mikael Fallqvist; Staffan Jacobsson; Mikael Olsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; Friction; Wear; Coatings; CVD; PVD; Alumina; Metal cutting; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials; Steel Forming and Surface Engineering;

    Abstract : The present thesis focuses on characterisation of microstructure and the resulting mechanical and tribological properties of CVD and PVD coatings used in metal cutting applications. These thin and hard coatings are designed to improve the tribological performance of cutting tools which in metal cutting operations may result in improved cutting performance, lower energy consumption, lower production costs and lower impact on the environment.

  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

  5. 13. Mechanical Load Identification for Spontaneous Tool Failure Monitoring

    Author : Jinming Zhou; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Material technology; Monitoring; Cutting force; Identification; Cutting; Manufacturing; materialteknik;

    Abstract : The problem of spontaneous cutting tool failure, such as tool chipping and breakage, is becoming more and more important in the manufacturing technology. The sponataneous tool failure is usually associated with the stresses subjected on the tool during a metal cutting process. READ MORE

  6. 14. Modelling and Analysis of Cutting Forces, Traction Loads and Thermoelasticity of Carbide Cutting Tools in Turning Operations - Theory and Experiments

    Author : Per-Olof Sturesson; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat Transfer; Finite Element Method; Metal Cutting; Turning; Material technology; Materiallära; materialteknik;

    Abstract : In modern manufacturing the production safety is often the key factor to achieve good product quality. Factors that influence the production safety are many, durability of machining centres, electric power supply and also the tool life. The tool life is governed by the ability to resist wear and failure. READ MORE

  7. 15. 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.
