2. 1. Tailored process gases for laser powder bed fusion

   Author : Camille Nicole Géraldine Pauzon; Chalmers University of Technology; []
   Keywords : Helium; Laser powder bed fusion; AM process productivity; Spatter particles; Residual oxygen; 316L stainless steel; Argon; Nitrogen; Additive manufacturing; Process atmosphere; Process stability; Residual stresses.; Ti-6Al-4V; Alloy 718;

   Abstract : Metal laser powder bed fusion (L-PBF) allows for production of complex components using the energy from a laser to locally melt micron-sized powder following a layer-wise approach. Considerable scientific efforts are focused on addressing the influence of the process parameters on the melting stability and the control of material properties, while developing necessary monitoring and characterization tools.

4. 2. The process atmosphere as a parameter in the Laser-Powder Bed Fusion process

   Author : Camille Nicole Géraldine Pauzon; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process stability; 316L stainless steel; Ti-6Al-4V; Laser-Powder Bed Fusion; processing atmosphere; process control; powder degradation; Additive Manufacturing;

   Abstract : Laser-Powder Bed Fusion (L-PBF) is an Additive Manufacturing (AM) technique that allows to produce near-net shape components of complex design. Applied to metallic materials, L-PBF allows to consolidate subsequent layers of powder using the heat from laser radiation. READ MORE

5. 3. Quantifying Operability of Working Machines

   Author : Reno Filla; Jan-Ove Palmberg; Kjell Ohlsson; Jonas Larsson; Linköpings universitet; []
   Keywords : Operability; machine harmony; operator workload; control effort; simulation; operator model; human operator; working machines; construction equipment; wheel loaders; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : In working machines the human operator is essential for the performance of the total system. Productivity and energy efficiency are both dependent not only on inherent machine properties and working place conditions, but also on how the operator manoeuvres the machine. READ MORE

6. 4. Teknisk och organisatorisk gestaltning : exemplet LKAB

   Author : Jan Johansson; Luleå tekniska universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

   Abstract : This thesis is concerned with showing how economic activity acquires its technical and organizational "Gestaltung". The term "Gestaltung" alludes to the classical understanding of the whole as being more than the sum of its parts; that is being both its constituent parts and their mutual relations. READ MORE

7. 5. Friction in threaded fasteners : Influence of materials and tooling

   Author : Mayank Kumar; Sergei Glavatskih; Erik Persson; Ellen Bergseth; Ian Sherrington; Robert Wood; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; Coating; Surface topography; Tightening speed; Additive manufacturing; Tightening condition; Assembly tool; Material; Friktion; Ytbehandling; Yttopografi; Åtdragningshastighet; Additiv tillverkning; Åtdragningsförhållanden; Monteringsverktyg; Material; Machine Design; Maskinkonstruktion;

   Abstract : Threaded fasteners represent the most common type of machine element, with a unique function that facilitates ease of assembly and disassembly. This ease of disassembly allows machine parts to be reused, refurbished, and recycled. READ MORE
