  1. 1. Effect of water contamination on the diffused content of hydrogen under stress in AISI-52100 bearing steel

    Author : Tajammal Imran; Maskinelement; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; hydraulics; Mechanical engineering; materialteknik; Materiallära; Material technology; Hydrogen Diffusion; Rolling Element; Machine Elements; Tribology; Hydrogen Embrittlement; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Abstract : Abstract Hydrogen embrittlement is a degradation process of mechanical/tribological properties (toughness, wear etc.) of mating steel surfaces. This is caused by the presence and interaction of hydrogen with applied stresses. Therefore, it is important to quantify the hydrogen content which could be dissolved under applied stresses in steel.

  2. 2. Active control of vibration and analysis of dynamic properties concerning machine tools

    Author : Henrik Åkesson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Control; Modal Analysis; Analog Controller;

    Abstract : Vibration in internal turning is a problem in the manufacturing industry. Vibrations appear under the excitation applied by the material deformation process during the machining of a workpiece. READ MORE

  3. 3. Analysis, Modeling and Simulation of Machine Tool Parts Dynamics for Active Control of Tool Vibration

    Author : Tatiana Smirnova; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Boring bar vibration in machine tools during internal turning operations is a pronounced problem in the manufacturing industry. Due to the often slender geometry of the boring bar, vibration may easily be induced by the material deformation process. One approach to overcome such vibration problems is to use active control of boring bar vibration. READ MORE

  4. 4. Improving Machining System Performance through designed-in Damping : Modelling, Analysis and Design Solutions

    Author : Lorenzo Daghini; Cornel Mihai Nicolescu; Miroslav Píška; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining performance; Cutting stability; Passive damping; High Damping Interface; Boring bar; Turret; SRA - Production; SRA - Produktion;

    Abstract : With advances in material technology, allowing, for instance, engines to withstand higher combustion pressure and consequently improving performance, comes challenges to productivity. These materials are, in fact, more difficult to machine with regards to tool wear and especially machine tool stability. READ MORE
