To achieve a smart factory, it requires solving challenges from different domains. The research work focuses on identifying the challenges faced in the existing product development and provides recommendation of overcoming the challenges by implementing MBSE in practise [1]. The Thesis aims to investigate and provide recommendations about the model-based system engineering approach. The research work is divided into different phases, where, the first phase focused on understanding the model-based system engineering (MBSE) methodology and the barriers in the exiting product development process. The barriers identified played a major role in defining the use case in the later stage of the research work.</span></div> <div><span style="font-size:14px"><br /></span></div> <div><span style="font-size:14px">The second phase focuses on investigating the MBSE tool i.e., Capella. This phase deals with understanding the architecture behind the modelling techniques in Capella. ARCADIA is the system engineering method which utilizes models with a collaborative, evaluation and exploitation of the architecture. The different stages of the architecture are analysed, and the operations performed on each stage are documented. The third phase of the thesis work focuses on performing the product modelling in the MBSE tool. In order to perform the modelling, rear view door mirror subsystem has been chosen as a system of reference. The different model elements corresponding to the Door mirror components are modelled in Capella and the trace links are established. In order to implement the requirement integration </span><span style="background-color:initial">with the models, System Modeling Workbench (SMW) platform provided by Siemens is utilized. SMW interface is a replica of Capella with some additional integration features. The final phase is to verify MBSE and the model elements against the use cases. A list of product development activities is defined in the form of use cases and its implementations are discussed. The MBSE platform is validated against the use cases and the results are captured. </span></div> <div><span style="font-size:14px">The outcome of the research work is the Proof of concept in SMW for Teamcenter which attempts to eliminate the barriers identified in the existing PD processes. The thesis work concludes with the list of benefits upon implementing MBSE. It also provides certain guidelines and best practise methods to be followed upon implementation of MBSE in a project.</span></div></div> <div><br /></div> https://www.chalmers.se/en/departments/ims/calendar/Pages/Amir-Malakizadi.aspxhttps://www.chalmers.se/en/departments/ims/calendar/Pages/Amir-Malakizadi.aspxA physics-based framework for tool wear estimation in machining<p>On-line presentation</p><p>​​Amir Malakizadi, Researcher at Materials and manufacture​ IMS, will give an presentation to become &quot;oavlönad docent&quot;.</p><div><span style="font-weight:700">​<img src="/SiteCollectionImages/Institutioner/IMS/Profilbilder/Amir%20Malakizadi%20kalender.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /></span>​​<span style="background-color:initial">Amir M</span><span style="background-color:initial">alakizadi, </span><span style="background-color:initial">Researcher at Materials and manufacture</span><span style="background-color:initial">​ IMS</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span></span><a href="https://research.chalmers.se/en/person/?cid=amirma" target="_blank" style="outline:0px"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />More about Amir Malakizadi​</a><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="font-weight:700">Abstract</span><div><div>Machining is often regarded as the final step in most manufacturing processes, where the final dimensional tolerances are adjusted, and the functional surfaces are made. The machinists and process planners often need to take several factors into account to deliver the machined parts with the targeted requirements set by the designers. For example, tools with specific characteristics in terms of macro- and micro-geometries should be chosen along with an appropriate range of cutting conditions to achieve the best results for a given machining process like milling or turning. The challenge arises when the tool geometry constantly changes during the machining processes due to wear, resulting in poor machined surface quality and impermissible dimensional tolerances. Hence, it is of great importance to estimate wear progression on the cutting edge which allows for a timely tool change in production lines.</div> <div>Tool wear in machining is influenced by many parameters such as the cutting conditions, cooling-lubrication, machining type and clamping system, and most importantly the chemico-physical properties of the tool and workpiece materials. In general, varying any of these parameters leads to the changes in the tribological conditions on the tool surfaces, provoking different thermo-mechanical wear mechanisms such as abrasion, adhesion, diffusion-dissolution, oxidation and (discrete) plastic deformation. In addition, the tribological condition at the tool-chip-workpiece interfaces changes with wear evolution on the cutting edge during the machining process. A thorough understanding of the complex interactions between the tool and workpiece materials can enable us to develop more reliable and robust models for tool wear prediction in machining. This, however, demands a multidisciplinary approach which combines different modelling and experimental methods.</div> <div>In this lecture, I present a multidisciplinary approach where the results of tailored machining tests, multi-scale modelling and simulations and tool-workpiece material characterisation are combined for a better understanding of tool wear mechanisms in machining and for developing a robust wear modelling platform. I briefly discuss the wear behaviour of coated and uncoated tools when machining different grades of workpiece materials, including cast irons, steels and superalloys. A hybrid physics-based modelling platform is then presented which combines the Finite Element (FE) simulation results with thermodynamic estimations of the solubility of the tool constituents into the workpiece materials, allowing for robust tool wear estimations in machining. This modelling approach is shown to be very efficient in comparison with the widely used experimental tool life equations and the other alternative approaches available in literature.</div> <div><br /></div> <div>Keywords: Machining, Tool wear, modelling, CALPHAD, characterisation​</div></div></div> <div><span style="font-size:14px"><br /></span></div>https://www.chalmers.se/en/departments/ims/calendar/Pages/Surface-and-thermoanalytical-studies.aspxhttps://www.chalmers.se/en/departments/ims/calendar/Pages/Surface-and-thermoanalytical-studies.aspxSurface- and thermoanalytical studies of chemical and physical processes during sintering of water-atomized iron and steel powder<p>Virtual Development Laboratory, laboratory, Chalmers Tvärgata 4C, M-huset</p><p>​Johan Wendel, Doctoral Student at Materials and manufacture​ IMS, defends his doctoral thesis.</p>​Examiner: Lars Nyborg, IMS<div><span style="font-size:14px"></span><span></span><div><span style="font-size:14px">Opponent: Jose Manueal Torralba, University Carlos III of Madrid </span></div> <div><span style="font-size:14px">Evaluation Committee: </span><span style="background-color:initial">Inger Odnevall Wallinder, KTH, </span><span style="background-color:initial">Håkan Engqvist, Uppsala University, </span><span style="background-color:initial">Srinivasan Iyengar, LTH, Lund University </span></div></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><a href="https://research.chalmers.se/en/person/wedelj" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read more</a></span></div> <div><br /></div>https://www.chalmers.se/en/departments/ims/calendar/Pages/Sustainable-Recycling-.aspxhttps://www.chalmers.se/en/departments/ims/calendar/Pages/Sustainable-Recycling-.aspxSustainable Recycling of The Printed Circuit Boards<p>On-line presentation.</p><p>​Artur Sagarov presents his master thesis project. On-line presentation.</p>​Examiner: Göran Gustafsson, IMS<div><br /></div> <div><strong>Abstract</strong></div> <div>The growing amount of unrecycled Waste Electrical and Electronic Equipment (WEEE) is posing a dreadful danger to the environment and all the inhabitants of the planet. The problem of the WEEE pollution did not appear overnight yet rather has a long history of by-times irresponsible behavior of the producers and consumers. The constant development of technology associated with the ever-demanding customers’ behavior has unleashed tonnes of outdated and discarded goods into landfills yet depleted the natural deposits for the fossils that were required for the future generations of the Electrical and Electronic Equipment (EEE). To tackle the problem of the pollution and depletion of the strategic resources for development, the society started to work on the strategies ensuring the future development needs and safe environment to live in. The recycling of the WEEE today became a lighthouse to the sustainable future where the environmental pollution and scarcity of the resources would be decreased, as the transition towards the sustainable future must be swift and  Meanwhile, the recycling itself can often be ground for the contradictions in utilization of the materials, especially when it comes to make a choice for target valuable materials and sacrifice materials of lower value, to obtain the profit from the recycling, while following the legislations that might force the recyclers to review their materials’ recovery agenda. Furthermore, the changing guidelines for recycling industries, that concern the recovery, utilization of materials and emissions from processes can surpass the expectations force the industry to look for new more sustainable approaches. Amid the demanding branches of materials being in recycling (recyclates) – the Waste Printed Circuit Boards (WPCB) which are rich with valuable resources, are at the same time complex matter to process, due to twisted and bounded structure trapping valuable materials within non-valuable materials.  Therefore, treatment of such complex matters requires an accurate approach in order to recover the highest possible amount of the precious materials, while leaving the rest unharmed, hence avoiding the emissions. This task requires a solution that could give user a control over these rich, but meanwhile rather unsorted and ever-changing source of valuable resources.  The study overviews the WEEE recycling framework state-of-the-art and brings in insights to the modern industry performance. At the same time, a potential solution to the WPCB recycling problem – unliberated valuable and invaluable materials was introduced. The disintegrator collision-based mill has proven itself effective with processing layered minerals to the fine and extra fine sizes, while has also shown its potential in being deployed as the size-reduction solution for liberating valuable and invaluable materials of WPCBs prior to enrichment process(-es) that would provide enriched metal concentrate to the refining stage of the recycling. The project seeks to find the answer to sustainability in the WPCBs processing, while reinforcing the circular pattern for the higher extent of the materials present in WPCBs structure. Achieving by achieving higher purity of the materials in the pre-treatment stage of the project, the enriched metal or non-metal concentrates would lower the emissions and increase the recovery rates for valuable materials from the WEEE.  <br /><div><br
