In this long procedure, training is required at any level, from operators to managers. Thus, interventions must be made so that Teaching and Learning Factories are upgraded towards integrating Industry 5.0. To this end, an evaluation system has to be made, assessing the feasibility of the three pillars’ integration. This procedure can concern a qualitative assessment (or a quantitative one) of the feasibility and the other implicated concepts, such as upskilling. At the same time, multilevel metrics are relevant, such as Key Performance Indicators (KPIs) related to company practices, manufacturing itself, jobs and trainees. Herein, a summative differential evaluation scheme, based on heuristic aspects, is explored, under the framework of the aforementioned TLF interventions. Examples of companies’ ex-ante characterization are given. Then, potential extensions are being discussed towards achieving formative evaluation and potentially towards KPIs.</div></div>","PeriodicalId":20535,"journal":{"name":"Procedia CIRP","volume":"132 ","pages":"Pages 122-128"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143510937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The spindle motor power, current and speed, as well as cutting forces were recorded in real time during turning. In longitudinal turning, the spindle motor power was found to be sensitive to the level of flank wear, which can be used for tool wear monitoring. Reliable cutting force prediction from spindle motor power (air cutting power + net cutting power) is also shown. In face turning, the tool exit time in the spindle motor power signal was found to be sensitive to tool geometry changes due to wear, suggesting that it can be used for tool wear monitoring. The spindle motor current and speed signals for all turning cases are also analyzed. The influence of the corresponding three-phase spindle motor connections (star and delta) on tool wear monitoring is discussed.</div></div>","PeriodicalId":20535,"journal":{"name":"Procedia CIRP","volume":"133 ","pages":"Pages 102-107"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143759550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A key application is the development of lattice structures, particularly Triply Periodic Minimal Surface Gyroid structures, which have attracted considerable attention for their unique properties, in different sectors from structural applications to heat exchange systems. As technological advancements continue, sustainability has become a critical focus in the manufacturing field, driven by both environmental and managerial factors. Consequently, the industry is increasingly adopting solutions that aim to reduce energy consumption and resource use, promoting cost-effective, eco-friendly production methods. This study investigates the impact of varying cell sizes in gyroid lattice structures, produced via Laser Powder Bed Fusion of metals, on sustainability and productivity. Four cubic samples with different cell sizes but constant wall thickness were analyzed. Additionally, a cradle-to-gate Life Cycle Assessment was performed to model the process and quantify the environmental impact, particularly carbon emissions. The results show that while smaller cell sizes enhance performance in engineering applications, they also lead to increased manufacturing time and higher energy consumption, posing challenges for sustainable production.</div></div>","PeriodicalId":20535,"journal":{"name":"Procedia CIRP","volume":"135 ","pages":"Pages 161-166"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144656237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reach this goal, cumulative generation capacity will likely have to increase by 400-800% from 2023 to 2035. One constraint on this increase is the number of wind turbine blade molds in commission, which limits the turbine blade production rate. These molds are built using a resin-fiberglass composite with a lead time of 26-40 weeks. The molds are then typically discarded not due to physical degradation but due to changes in the blade geometry requirements for new wind sites. To minimize blade production lead time, a new modular mold is proposed that can be reconfigured to produce a range of different blade geometries. A cradle-to-gate manufacturing cost, energy and lead time model was constructed to compare a durable additively manufactured modular aluminum mold to the conventionally produced fiberglass composite mold. Modular molds are estimated to be quicker, but more expensive and energy-intensive to build than conventional molds. A US level wind turbine blade fleet analysis suggests modular molds could lead to around 25% fewer molds needing to be produced cumulatively by 2035 to meet the clean electricity target.</div></div>","PeriodicalId":20535,"journal":{"name":"Procedia CIRP","volume":"135 ","pages":"Pages 167-174"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144656238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, the varying quality state of secondary products, components and materials makes it difficult to manage the variety of paths and involved stakeholders towards the reintroduction of secondary materials into their next use phase. B2B marketplaces enable the simple integration of the participating stakeholders along a product’s lifecycle into a common value chain management and enable the formation of dynamic, needs-oriented supply chains. Traceability tools, like the emerging Digital Product Passport (DPP), ensure a continuous information flow among all lifecycle actors. This paper shows how the DPP can be leveraged to facilitate the processes at the end of the product life. Specifically, it presents an approach to integrate Quality Assessment into the reverse supply chain. It proposes to utilize a DPP based on the Asset Administration Shell to establish a common understanding of an object’s quality state between stakeholders. The availability of reliable, standardized quality information has the potential to improve supplier-buyer matchmaking on B2B marketplaces and to increase trust. The concept is demonstrated on a usecase in a dynamic manufacturing environment.</div></div>","PeriodicalId":20535,"journal":{"name":"Procedia CIRP","volume":"135 ","pages":"Pages 606-611"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144656261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
