  1. 1. Condition monitoring of machine tools and machining processes using internal sensor signals

    Author : Jari Repo; Mihai Nicolescu; Dragos Axiente; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; condition monitoring; machine tool; machining process; milling; position encoders; signal analysis; Mechanical engineering; Maskinteknik; Materials science; Manufacturing and materials engineering;

    Abstract : Condition monitoring of critical machine tool components and machining processes is a key factor to increase the availability of the machine tool and achieving a more robust machining process. Failures in the machining process and machine tool components may also have negative effects on the final produced part. READ MORE

  2. 2. Human motion prediction using wearable sensors and machine Learning

    Author : Binbin Su; Elena M. Gutierrez-Farewik; Christian Smith; Neil Cronin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wearable sensors; gait segmentation; lower limb angular velocity; machine learning; deep learning; reinforcement learning; Engineering Mechanics; Teknisk mekanik;

    Abstract : Accurately measuring and predicting human movement is important in many contexts, such as in rehabilitation and the design of assistive devices. Thanks to the development and availability of a wide variety of sensors, scientists study human movement in many settings and capture characteristic properties unique to individuals as well as to larger study populations.

  3. 3. Non-contact measurements and modelling of milling machine tool vibrations

    Author : Matti Rantatalo; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Abstract : This thesis concerns the development of non-contact measurement methods and analysis of rotors. The methods have been verified and applied to milling machine spindles in order to investigate the speed dependency in the milling machine spindle dynamic. The research was financed by the Swedish Agency for Innovation Systems (Vinnova). READ MORE

  4. 4. Machine tool vibrations and violin sound fields studied using laser vibrometry

    Author : Kourosh Tatar; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Abstract : The knowledge of the dynamic behaviour of a milling process is very important for finding an optimum process window. In today's manufacturing industry the machining parameters are often predicted using experimental data from non-rotating spindles. READ MORE

  5. 5. Intelligent fault diagnosis and predictive maintenance for a bearing ring grinder

    Author : Muhammad Ahmer; Pär Marklund; Fredrik Sandin; Kim Berglund; Martin Gustafsson; Peter Krajnik; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analysis; grinding machines; diagnostics; predictive maintenance; condition monitoring; intelligent fault diagnosis; Maskinelement; Machine Elements;

    Abstract : Predicting the failure of any structure is a difficult task in a mechanical system. However complicated and difficult the prediction might be, the first step is to know the actual condition of the system. READ MORE
