  1. 6. Estimation of Machining System Dynamic Properties - Measurement and Modelling

    Författare :Tomas Österlind; Andreas Archenti; Mihai Nicolescu; Leif Kari; Amir Rashid; Thomas Abrahamsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining system; Operational dynamic parameters; Displacement map; Contactless excitation and response system; SRA - Production; SRA - Produktion; Production Engineering; Industriell produktion;

    Sammanfattning : Dynamic characteristics of machining systems are analysed for improved understanding of both structural and process properties. The thesis stresses the use of testing methods under operational like conditions as these are more representative of closed loop systems, such as machining systems, as compared to conventional testing methods.

  3. 7. Strategic and operational capabilities in steel production : Product variety and performance

    Författare :Joakim Storck; Bengt Lindberg; Christer Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel production; system dynamics; product variety; production strategy; cost models; Manufacturing engineering; Produktionsteknik;

    Sammanfattning : Steel producers that employ niche market strategies are continuously seeking to reduce production cost while maintaining adiverse product mix. The business model is typically based onmarketing of high–strength special or stainless steels. LÄS MER

  4. 8. A Computational Framework for Control of Machining System Capability : From Formulation to Implementation

    Författare :Andreas Archenti; Cornel Mihai Nicolescu; Mamoru Mitsuishi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining system; Stability; Statistical Dynamics; Elastic Linked System ELS ; Operational Dynamic Parameters ODP ; Loaded Double Ball Bar LDBB ; Virtual Machining System Engine VMSE ; Contactless Excitation and Response System CERS .; SRA - Production; SRA - Produktion;

    Sammanfattning : Comprehensive knowledge and information about the static and dynamic behaviour of machine tools, cutting processes and their interaction is essential for machining system design, simulation, control and robust operation in safe conditions. The very complex system of a machine tool, fixture and cutting tools during the machining of a part is almost impossible to model analytically with sufficient accuracy. LÄS MER

  5. 9. Data-driven throughput bottleneck analysis in production systems

    Författare :Mukund Subramaniyan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; maintenance; machine learning; data-driven; manufacturing; manufacturing system; production system; artificial intelligence; Throughput bottlenecks;

    Sammanfattning : Production systems and production management are getting smart. Manufacturing companies are increasingly adopting digital solutions to monitor and manage production systems. By adopting digital solutions, it has become possible for manufacturing companies to collect huge volumes of widely varying production system data. LÄS MER

  7. 10. Supporting Production System Design Decisions through Discrete Event Simulation

    Författare :Erik Flores-García; Magnus Wiktorsson; Björn Johansson; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Innovation and Design; innovation och design;

    Sammanfattning : Manufacturing companies are increasingly required to deal with and introduce significant changes in their production systems to gain a competitive advantage. The production system design process is widely considered a means of introducing such changes, and decisions made during design are viewed as critical to its characterization and performance. LÄS MER
