For some of the afore mentioned examinations there are directly applicable regulations, while in more specific situations, the particularities of the enclosure and its use requirements, force to an adaptation of the procedures applied to these requirements. Based on this, a method and a test plan are proposed to make sure that the system is protected against the environmental conditions in which it is installed, both for the purposes of humidity, solid particles, mechanical or thermal stresses, as for the action of aging by ultraviolet radiation among other circumstances.","PeriodicalId":46357,"journal":{"name":"Advances in Science and Technology-Research Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135834227","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}

In addition, the quality control of these operations is performed following verification instructions. Traditionally, these work and verification instructions were based on 2D documentation (on paper or digital screen), prepared by manufacturing engineering, and made available to operators by manufacturing engineering systems (MES) when required. Over the last decade, Airbus has made significant progress in ensuring the digital continuity of processes, exploiting information from the industrial digital mock-up (iDMU) downstream, favoring the preparation and use of assembly and quality instructions through new techniques, such as lightweight 3D viewers, or augmented reality. This paper describes experiences of implementation of augmented reality (based on laser or holographic technology) in the workshop, both for assembly and quality processes. Several use cases are analyzed, comparing both technologies, explaining their pros and cons, and justifying the use of each of them in each process.","PeriodicalId":46357,"journal":{"name":"Advances in Science and Technology-Research Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135834232","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}

Although design processes are commonly developed with digital workflows, in reverse engineering different and independent phases with bottlenecks between them are involved. The present work addresses the challenge of establishing a continuous and efficient data flow between the three-dimensional digitized data obtained with 3D scanning and the automatic generation of NC toolpaths. A methodology is developed for the generation and optimization of NC toolpaths directly from the 3D point cloud data obtained through the three-dimensional scanning of pre-existing geometries. The methodology consists of an algorithm developed with Grasshopper, a script for visual programming in Rhino’s interface. It does not only attempt to reconstruct the three-dimensional geometry of the scanned part but also, it directly generates the tool paths and optimizes them with evolutionary optimization algorithms that are integrated in the methodology. A case study is developed for TMU-SIO TOWGTAI machining center with the proposed methodology. Finally, the obtained results and the efficiency of the methodology are analyzed and presented.","PeriodicalId":46357,"journal":{"name":"Advances in Science and Technology-Research Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135834467","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}

The manufacturing process consists of ring machining and component assembly, including intensive quality controls. This work proposes the integration of machine learning models associated with the manufacture of the double outer ring and the two inner rings in the DT. The models are trained with real data, so that the DT can predict the behavior of the production process under changing conditions of ongoing processes, machines or materials, and optimal operating conditions can be predicted. The DT has been developed and integrated with the aim of guiding production by proposing optimal machine configurations. To this end, different stations have been modeled and integrated into the DT as independent modules: grinding machines, inner and outer rings pairing module, and a module for calculating the optimal family of rings to be ground. After integrating the DT in the line, results show not only a raise in the line efficiency but also a decrease in the overall scrap ratio.","PeriodicalId":46357,"journal":{"name":"Advances in Science and Technology-Research Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135834027","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}

These concepts allow the application of intelligent manufacturing within the Aerospace industry, responsible for transforming manufacturing processes using software technologies based on artificial intelligence, to automate the Sheet Metal Parts modeling process and get more accurate data. Therefore, it applies to Models for Manufacturing (MfM) in product projects, a recent methodology that presents an organization for formally defined information and knowledge. However, MfM does not consider information tracing and inconsistency analysis in the modeling phases. Based on this paradigm, a solution is proposed by developing and adopting methods, processes, and tools of Ontology-Based Engineering based on the MfM model to obtain data. In addition, Semantic Technologies are used for data processing through an OWL structure, also formalizing the information through semantic rules in SWRL. This research aims to: (I) Obtain data extracted from Sheet Metal Parts and structure them from ontology; (II) Formalize information about this data using semantic rules; (III) Validate information between product and manufacturing projects to identify and address inconsistencies in advance.","PeriodicalId":46357,"journal":{"name":"Advances in Science and Technology-Research Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135834484","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}

Industry 4.0 is causing paradigms to change at an industrial level, which, together with the technological advance of communication networks and the internet, will allow for achieving complete digitization of manufacturing processes. Digitization solutions implementation is hampered by the lack of adequate management procedures and methodologies to simplify the requirements analysis and the incorporation of improvements using I4.0.There are several methodologies for managing and controlling projects, but they need to adapt according to the required migration of systems from Industry 3.0 to Industry 4.0. A literature review has allowed identifying the most important characteristics of industry 4.0 based on the main digital enablers. Nowadays, any migration of technological systems also requires using an appropriate management methodology, replacing or complementing the traditional waterfall methodology, that can be easily controlled and where errors can be predicted and corrected in the shortest possible time. These new tools are important to facilitate the implementation of I4.0, especially in regions and companies with a low tradition of adaptation to technological changes.In this work, a novel concurrent methodology framework based on engineering and adapted Scrum work is proposed to implement I4.0 technology migration, using technology enablers. It was designed to provide several advantages, namely: feedback provided every certain period of time to correct errors, the use of multidisciplinary teams, and its easy implementation. This adapted Scrum & concurrent methodology framework will offer a new management approach to the I4.0 transition projects, which we expect can be applied at the industrial level, especially in developing countries.","PeriodicalId":46357,"journal":{"name":"Advances in Science and Technology-Research Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135834691","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}
