4. 7. System Evaluation and Learning in Evolvable Production Systems : Preliminary considerations and research directions

   Author : Pedro Neves; Mauro Onori; Luis Ribeiro; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Learning; Evolvable Production Systems; SRA - Production; SRA - Produktion;

   Abstract : Dynamicity and unpredictability related to markets is strongly hardening companies’ mission to follow them and satisfy customer needs mainly due to the lack of adequate engineering mechanisms. These effects are felt more intensively in markets where low volumes and high customisation are needed since this requires constant changes in systems that can range from simple setups to total line re-configuration and re-programing.

5. 8. Uncertainty Management for Automated Diagnostics of Production Machinery

   Author : Károly Szipka; Andreas Archenti; Giuliano Bissacco; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uncertainty Management; Automated Diagnostics; Inertial Measurement Unit; SRA - Produktion; SRA - Production;

   Abstract : Neither production machinery, nor production systems will ever become completely describable or predictable. This results in the continuous need for monitoring and diagnostics of such systems in order to manage related uncertainties. READ MORE

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

   Author : Tomas Österlind; Andreas Archenti; Mihai Nicolescu; Leif Kari; Amir Rashid; Thomas Abrahamsson; KTH; []
   Keywords : 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;

   Abstract : 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.

7. 10. Mechanical Properties of Resistance Spot Welds in Lightweight Applications

   Author : Davood Afshari; Zuheir Barsoum; Arne Melander; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spot Weld; Aluminum alloy; Mechanical Properties; Finite Element; SRA - Production; SRA - Produktion;

   Abstract : This licentiate thesis is concerned with residual stresses in aluminum alloy 6061-T6 resistance spot welded joint. Several topics related to mechanical strength of welded structures are treated such as; nugget size and microhardness and microstructures of weld zone and their influence on mechanical strength of welded structure, failure load measurement using tensile-shear test, resistance spot welding simulation, residual stress measurement by X-ray diffraction method and analysis effect of welding parameters on the mechanical strength and the residual stresses.
