1. 1. An AI approach for quality improvement in heat treatment processing

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Industriell teknik

   Författare :Kruse Gustav; Lotta Åhag; [2022]
   Nyckelord :Artificial intelligence; heat treatment; mining; steel; smart manufacturing; pipeline; hardness; cooling; quality improvement;

   Sammanfattning : Export of heat treated steel goods has an important impact on the Swedish economy which brings performance demands and expectations on production to keep a competitive market position. Sustainability and efficiency are two important aspects in meeting these demands. LÄS MER

3. 2. Performance and Wear Behaviour of Coated and Uncoated Cemented Carbide Tools during Milling of Titanium Alloys

   Master-uppsats, Lunds universitet/Industriell Produktion

   Författare :Juan Manuel Bello Bermejo; [2022]
   Nyckelord :Titanium alloys; milling; wear mechanisms; wear behaviour; cutting tool performance.; Technology and Engineering;

   Sammanfattning : Purpose – The purpose of this project is to study the performance of uncoated versus coated cemented carbide tools when performing milling operations in heat treated titanium alloys, with the goal of establishing a base line of knowledge and methodology linked to these difficult-to-machine materials relevant for the metal cutting industry. Design/methodology/approach – The work that is carried out in this project comprise both literature review, that is presented as the state of the art as the necessary theoretical background to understand what is done; and experiments, that were designed and executed at Seco Tools in Fagersta in order to achieve the primary goal, testing and comparing different scenarios where cutting parameters played a key role.

4. 3. Multivariate Data Analysis on (Ti,Al)N Arc-PVD coating process : MVDA of the growth parameters thickness, stress,composition, and cutting performance

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemi

   Författare :Per-Olof Öqvist; [2021]
   Nyckelord :chemistry; material; coating; statistics; PLS; PCA; kemi; material; beläggning; statistik; PLS; PCA;

   Sammanfattning : This diploma work was done at Seco Tools AB (SECO) in Fagersta and aimed to evaluate the possibility to model the relationship between deposition data, deposition properties and, cutting performance of a (Ti,Al)N coating on cutting inserts by applying the Multivariate Data Analysis (MVDA) modeling technique Partial Least Squares Projection to Latent Structures Modeling (PLS). Cathodic Arc Deposition (Arc-PVD) was the PVD technique focused on this study. LÄS MER

5. 4. Form-based codes och design codes i en svensk planeringskontext : En komparativ studie mellan länder

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Johanna Mårtensson; [2021]
   Nyckelord :Development control; Detailed plan; Quality program; Architecture policy; New Urbanism; Transect; Sweden; USA; England; Urban planning; Bebyggelsereglering; Detaljplan; Kvalitetsprogram; Arkitekturpolicy; Nyurbanism; Transekt; Sverige; USA; England; Stadsplanering;

   Sammanfattning : System för planering och bebyggelsekontroll måste hantera många utmaningar. Svårigheterna och den påverkan dessa system har på den fysiska miljön gör ämnet ständigt aktuellt att undersöka och försöka utveckla. Examensarbetet gör detta genom att jämföra systemet i Sverige med det i andra länder. LÄS MER

7. 5. Toward predictive maintenance in surface treatment processes : A DMAIC case study at Seco Tools

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Författare :Martin Berg; Albin Eriksson; [2021]
   Nyckelord :Predictive maintenance; Industry 4.0; Data-driven maintenance; chemical vapour deposition; wet blasting;

   Sammanfattning : Surface treatments are often used in the manufacturing industry to change the surface of a product, including its related properties and functions. The occurrence of degradation and corrosion in surface treatment processes can lead to critical breakdowns over time. LÄS MER
