  2. 1. Simulation-based feedback control of welding processes

    Author : Fredrik Sikström; Bengt Lennartson; Gunnar Bolmsjö; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element modelling; Heat transfer; Model order reduction; Sensors; Weld simulation Controller design; Automatic control; Reglerteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Fusion welding for joining of metals is an important manufacturing process widely used in industry, and very appreciated for its usefulness. This thesis presents a strategy dealing with the problem of designing feedback control for robotised welding. READ MORE

  4. 2. Sheet metal forming in the era of industry 4.0 : using data and simulations to improve understanding, predictability and performance

    Author : Sravan Tatipala; Johan Wall; Christian Johansson; Tobias Larsson; Mehdi Tarkian; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modelling; Simulation; Industry 4.0; Sheet Metal Forming; Process Monitoring; Process Control; Automation; Finite Element Analysis; Smart Manufacturing; Mechanical Engineering;

    Abstract : A major issue within automotive Sheet Metal Forming (SMF) concerns ensuring desired output product quality and consistent process performance. This is fueled by complex physical phenomena, process fluctuations and complicated parameter correlations governing the dynamics of the production processes. READ MORE

  5. 3. A Sequential Control Language for Industrial Automation

    Author : Alfred Theorin; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grafchart; service oriented architecture; event-driven architecture; flexible production systems; industry 4.0; real-time; FMI; PID;

    Abstract : Current market trends for industrial automation are the need for customizable production, shorter time to market, and powerful global competitive pressure. Based on these trends two challenges have been identified: 1) flexible production systems and 2) integration and utilization of devices and software. READ MORE

  6. 4. Materials Handling in Production Systems: Design and Performance of Kit Preparation

    Author : Patrik Fager; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; kitting; kit preparation; order picking; materials supply systems;

    Abstract : This thesis focuses on processes for kit preparation, which are applied with the materials supply principle of kitting in production systems for mixed-model assembly. With kitting, assembly processes are supplied with portions of pre-sorted components, and each portion makes up a kit that holds the components needed for one assembly object at one or several assembly processes.
