2. 1. Towards improvement of geometrical quality for manual assembly parts

   Author : Mikael Rosenqvist; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calculation model; geometry system; Interview; assessment; action cost.; assembly; error; ergonomics; assembly complexity; design for assembly; robust design; complexity; manual assembly; sustainable; tolerance analysis and design; CAT; quality; failure; action cost; assembly ergonomics;

   Abstract : Geometrical variation affects all mass-produced products. This variation will lead to deviations from the nominal design of the product both in terms of aesthetical and functional properties. Geometrical variation originates either from the manufacturing of the parts or from the assembly process.

4. 2. Planning Robotic Assembly Sequences

   Author : Domenico Spensieri; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; robot routing and scheduling; path planning; Assembly planning; geometrical variation; cycle time optimization;

   Abstract : In the automotive industry, short ramp up times and high product quality drive the development toward state-of-the-art solutions both in the research and industrial perspective. In addition to that, a sustainable industry requires optimized equipment utilization, in terms of materials used and consumed energy. READ MORE

5. 3. Machinability variations in Alloy 718 —With focus on machining of turbine components

   Author : Pajazit Avdovic; Industriell Produktion; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polar diagram; flank wear; ceramic tool; variation in material; tool wear; tool life; machinability; Inconel; Alloy 718; Machining; notch wear;

   Abstract : In gas turbine engine, nickel base alloy, such as Alloy 718, accounts for almost half of the total material requirement. Nickel-base superalloys are used for gas turbine components mainly because of their outstanding strength and resistance to oxidation at high temperatures (> 550°C). READ MORE

6. 4. Connections for Timber-Framed Structures - Assembly Properties and Structural Behaviour

   Author : Dan Engström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frames; nails; connections; structures; interaction; glue; assembly; timber; economy; semi-rigidity; adhesive; joints; splices;

   Abstract : By tradition, the design and development of connections has focused on the optimization of strength and stiffness. The subject of this thesis is the interaction between the assembly and structural properties of connections for timber-framed structures. READ MORE

7. 5. An Analysis of the Proactive Approach as a Potential Tool for Adaptability in Production Systems

   Author : Kerstin Dencker; Mauro Onori; Lena Mårtensson; Monica Bellgran; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Assembly; production system design; proactivity; human-machine collaboration; SRA - Production; SRA - Produktion;

   Abstract : Competitive systems for manufacturing, especially assembly systems, have to cope with frequent changes of external as well as internal demands. A proactive behaviour in an assembly system should make it capable of rapid changes and have an ability to handle frequent changes and disturbances. READ MORE
