In the current range of tabletops, similarities can be found between several of them. The purpose of this project is to find the similarities among the tabletops, propose to eliminate tabletops with too many similarities and suggest a potential platform for the tabletops.   </div> <div><br /></div> <div>The objectives of the project were: </div> <div><br /></div> <div>1. What are the major factors (organizational, cost, logistics, production) in the current IKEA’s tabletops strategy (not platform-based)? What needs to be changed (in IKEA’s lean development process) to move for a platform-based approach?</div> <div><br /></div> <div>2. What are the cost factors (development, production, and logistics) in today’s product portfolio of tabletops and how could a platforming strategy affect these factors? </div> <div><br /></div> <div>3. How to calculate the supply cost of today’s product portfolio compared to a platform-based approach portfolio? </div> <div><br /></div> <div>4. How to analyse (calculate complexity, and standardization) the current products (Tabletops) in an efficient way in order to develop the right standard procedure for other products (beyond tabletops)? </div> <div><br /></div> <div>5. What metrics exists that identify the trade-off of internal complexity vs customer options? How can they be used to evaluate the current range and compare future scenarios?</div> <div><br /></div> <div>A literature study was made to deepen the knowledge in the subject and especially about platform development and modularization management. The data collection consisted of mainly literature, interviews and through databases for collecting information regarding the tabletops. The collected data were the foundation for the further research which consisted of set up important parameters for the tabletops, creating a commonality plan and suggesting what tabletops having the biggest potential for creating a platform in and which tabletops to eliminate because of too many similarities.</div> <div><br /></div> <div>The project was carried out in collaboration with IKEA of Sweden located in Älmhult and Chalmers University of Technology located in Gothenburg. Most of the work was done on campus at Chalmers and online because of the pandemic and distance barrier. </div></div> <div><br /></div> https://www.chalmers.se/en/areas-of-advance/production/calendar/Pages/Seminar-on-circular-economy.aspxhttps://www.chalmers.se/en/areas-of-advance/production/calendar/Pages/Seminar-on-circular-economy.aspxSeminar on circular economy<p>Online</p><p>​​Production Area of Advance s​eminar series</p>​<span style="background-color:initial">A presentation about the research and education in Circular Economy.</span><div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">Speaker: Maria Ljunggren, Associate Professor in Sustainable Materials Systems, Department of Technology Management and Economics.

This results in high surface reactivity of the powder and hence high sensitivity of the powder to e.g. oxidation, starting from powder manufacturing and following powder handling and processing using variety of powder metallurgy and additive manufacturing processes. This is especially important in case of reactive metals as Ti- and Al-alloys and complex alloys containing elements with high sensitivity to oxygen as Ni-base super-alloys, stainless steels, tool steels, etc. In order to assure necessary powder quality, variety of powder manufacturing methods are used for powder manufacturing, selection of which is based on powder alloy composition, required purity, powder quantity and cost. However, powder surface chemistry will undergo significant changes in terms of oxide transformation and distribution in the consolidated material, that is determined by the powder alloy composition and consolidation process applied. Hence, powder surface chemistry determines requirements to the consolidation process and its efficiency as well as properties of the consolidated material when it comes to the final density and mechanical performance. </div> <div>Analysis of the powder surface chemistry and the assessment of thermodynamics and kinetics of surface reactions are of prime importance for understanding the changes in surface composition related to the process conditions during powder consolidation. Such understanding is of vital importance for manufacturing of oxide-free high-performance components. The analysis is typically performed by means of advanced surface characterisation and thermal analysis techniques in combination with the modelling of the effect of processing conditions. Such experimental input in combination with thermodynamic simulation allows to establish generic models of oxide reduction/formation/transformation in different alloy systems during powder consolidation using different powder metallurgy processes (conventional press&amp;sinter, hot isostatic pressing, liquid phase sintering, etc.) as well as powder-based additive manufacturing (powder bed fusion, binder jetting, material extrusion, etc.). </div> <div>Keywords: powder metallurgy, powder-based additive manufacturing, surface oxide, powder consolidation, oxide transformation.</div> <div><br /></div> <div><a href="/en/Staff/Pages/hryha.aspx" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />More about Eduard Hryha​</a></div> <div><br /></div> <div></div> https://www.chalmers.se/en/centres/wingquist/calendar/Pages/Annual-Seminar-2020.aspxhttps://www.chalmers.se/en/centres/wingquist/calendar/Pages/Annual-Seminar-2020.aspxWingquist Laboratory Annual Seminar 2020<p>Virtual Development Laboratory, Chalmers Tvärgata 4C, M-huset</p><p>We celebrate 20 years of excellent research on Digital Product Realization!
