  2. 31. Surface integrity on post processed alloy 718 after nonconventional machining

    Author : Jonas Holmberg; Tomas Beno; Anders Wretland; Johan Berglund; Mikael Olsson; RISE; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; Non-conventional machining; post processing; surface integrity; Microstructure; Residual stress; Electron back scattering diffraction; Material removal rate; Manufacturing; Surface and Joining Technology; Bearbetnings-; yt- och fogningsteknik; Production Technology; Manufacturing and materials engineering;

    Abstract : There is a strong industrial driving force to find alternative production technologies in order to make the production of aero engine components of superalloys even more efficient than it is today. Introducing new and nonconventional machining technologies allows taking a giant leap to increase the material removal rate and thereby drastically increase the productivity. READ MORE

  4. 32. Human-centric process planningfor Plug & Produce : Digital threads connecting product design withautomated manufacturing

    Author : Anders Nilsson; Fredrik Danielsson; Kerstin Johansen; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plug Produce; Digital Threads; Industrial Manufacturing; Process Planning; Multiagentsystem; Processplanering; Plug Produce; Digitala kedjor; Industriell Tillverkning; Flexibel Automation; Production Technology; Produktionsteknik;

    Abstract : Adaptations to a fluctuating market and intensified customer demands for unique products are a challenge for manufacturers. Manual manufacturing is still the most flexible, nevertheless, automation ensures stable quality, minimizes wear and tear of the operators, and contributes to a safer and better working environment as the distance between the operator and the process can be increased and screened off.

    Abstract : Additive Manufacturing (AM) is on the verge of causing a downfall to conventional manufacturing with its huge potential in part manufacture. With an increase in demand for customized product, on-demand production and sustainable manufacturing, AM is gaining a great deal of attention from different industries in recent years. READ MORE

  6. 34. Smart Maintenance - maintenance in digitalised manufacturing

    Author : Jon Bokrantz; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; digitalisation; production system; maintenance; manufacturing; industry 4.0;

    Abstract : What does digitalised manufacturing entail for maintenance organizations? This is a pressing question for practitioners and scholars within industrial maintenance management who are trying to figure out the best ways for responding to the rapid advancement of digital technologies. As technology moves faster than ever before, this is an urgent matter of uttermost importance. READ MORE

  7. 35. Microstructure model for Ti-6Al-4V used in simulation of additive manufacturing

    Author : Corinne Charles Murgau; Lars-Erik Lindgren; Niklas Järvstråt; Robert Pederson; Sören Sjöström; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titanium alloy; Ti-6Al-4V; Welding; Metal deposition; Additive manufacturing; Wire feed; Finite Element Method; Microstructure model; Johnson-Mehl-Avrami- Kolmogorov; Thermally driven; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik; Material Mechanics;

    Abstract : This thesis is devoted to microstructure modelling of Ti-6Al-4V. The microstructure and the mechanical properties of titanium alloys are highly dependent on the temperature history experienced by the material. The developed microstructure model accounts for thermaldriving forces and is applicable for general temperature histories. READ MORE
