In this study, we introduce a stepwise approach to determine absolute environmental sustainability targets during the product development process. The approach integrates top-down factors such as planetary boundaries, IPCC carbon budgets and sharing principles shaping these targets. Furthermore, we assess the influence of bottom-up factors such as the selection of raw material suppliers and production location in achieving them. The application of the approach is illustrated for the case study of a traction battery. The potential future applications and limitations of the proposed stepwise approach are discussed.</p><p>Electric vehicle; Sustainable development; Absolute sustainability</p></div>","PeriodicalId":55256,"journal":{"name":"Cirp Annals-Manufacturing Technology","volume":"73 1","pages":"Pages 1-4"},"PeriodicalIF":3.2,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0007850624000544/pdfft?md5=859a6cbfa0a4b47f66434409506d1cca&pid=1-s2.0-S0007850624000544-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141959527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper first examines the established models that continue to constitute the fundamental knowledge base in fixed-abrasive technology. Special attention is given to geometry, kinematics, and thermomechanical modeling. Recent advances in process monitoring and big data analytics provide new opportunities to further strengthen the state of the art in modeling through data-driven approaches. In addition, examples on how models – implemented in simulation software – can be used to predict and optimize industrial operations have been demonstrated.
