  1. 1. Alternative binder hardmetals for steel turning

    Författare :Lisa Toller; Susanne Norgren; Hans-Olof Andrén; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; hardmetal; cemented carbide; alternative binder; steel turning; scratch testing; plastic deformation; EBSD; transformation toughening; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : The goal of this work is to understand how the wear and deformation mechanisms of hardmetalinserts change when the cobalt binder phase is replaced with a dierent metal or analloy. The focus is on inserts for steel turning. The work presented in this licentiate thesisconsists of the rst steps. LÄS MER

  2. 2. A Statistical Approach to Near Dry Machining

    Författare :Marina Isaksson; Chalmers University of Technology; []
    Nyckelord :cooling; turning; carbide; lubrication.; aerospace; Near-dry-machining; ceramic; MQL;

    Sammanfattning : To substantiate the implementation of near dry machining in such a demanding industry as the aerospace industry, it is essential to have a broad understanding about the phenomena behind near dry machining. The conditions for the aerospace industry is stated in such a way, that changes or method development of the process had to be very well founded before it could be executed. LÄS MER

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

    Författare :Varun Nayyar; Chalmers University of Technology; []
    Nyckelord :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;

    Sammanfattning : 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. 4. Robots and Moral Agency

    Författare :Linda Johansson; Sven Ove Hansson; Björn Petersson; KTH; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; machine ethics; UAV; laws of war; robot morality; moral agency; Moral; Turning Test; Philosophy subjects; Filosofiämnen;

    Sammanfattning :   Machine ethics is a field of applied ethics that has grown rapidly in the last decade. Increasingly advanced autonomous robots have expanded the focus of machine ethics from issues regarding the ethical development and use of technology by humans to a focus on ethical dimensions of the machines themselves.

  5. 5. Performance Testing of Cutting Fluids and Tool Holders in Metal Cutting

    Författare :Varun Nayyar; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chip Microstructure; Torque; Drilling; Compressed air; Turning; Tool-holding; Force.; Tapping; Keyword: Cutting Fluid;

    Sammanfattning : 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. LÄS MER
