Applying model-driven paradigm: CALIPSOneo experience

Model-Driven Engineering paradigm is being used by the research community in the last years, obtaining suitable results. However, there are few practical experiences in the enterprise field. This paper presents the use of this paradigm in an aeronautical PLM project named CALIPSOneo currently under development in Airbus. In this context, NDT methodology was adapted as methodology in order to be used by the development team. The paper presents this process and the results that we are getting from the project. Besides, some relevant learned lessons from the trenches are concluded.Ministerio de Ciencia e Innovación TIN2010-20057-C03-02Junta de Andalucía TIC-578

Product Lifecycle Management - Application of Patterning Methods to Gas Turbine Blades and Creation of Learning Materials

To compete in the global marketplace, companies need to embrace virtual design and manufacturing methods. Product Lifecycle Management (PLM) embodies both the workflow processes and tools to bring forth products from conception to design to fabrication to service to decommissioning, and to eventual recycling. In response to the growing demand for engineers and technicians with these critical skills, colleges and universities should introduce these virtual tools through seminars, software workshops, and computer laboratory sessions. Some of the opportunities in the PLM Center at Clemson University include short courses on PLM practices, focused software training sessions, hands-on exploration activities, and research projects. The participants across campus include creative inquiry students, capstone design classes, graduate researchers, and community outreach for K-12 students. Through these interactions, participants will gain insight into the challenges and opportunities with virtual engineering processes and software. The recent worldwide pandemic has demonstrated the need for engineers skilled in virtual design methods to enable the digital design, manufacturing, and support processes to occur in, and remote of, the workplace. Computer-aided design (CAD) and computer-aided engineering (CAE) methods embody the software tools that bring forth products from conception to design. A variety of packages are available, which allow for the progress of a product to be tracked and detailed changes to be made along the way. One complex product currently designed using CAE software is a natural gas fired turbine for electrical power generation. In these thermo-dynamic rotational systems, blade cooling using internal forced airflow is vital to withstand the operating temperatures in the combustion chamber. Accordingly, ribbed surface disruptors, known as turbulators, are placed inside the turbine blades to promote air mixing to help remove heat from the hot surfaces. Three CAE patterning features will be examined to create these turbulators with evaluation metrics based on the execution speed, accessibility, accuracy, adaptability, and relevance. The numerical case study results revealed that the face pattern method was the most suitable option with productivity time improvements of 5% in comparison to the feature and geometry pattern approaches. The feature pattern method proved to be viable for smaller modeling changes which require significant detail. However, the geometry patterning method did not show any indications of being a usable option over the others in any scenario tested. To prepare the next generation of engineers for these PLM processes and software tools, a PEER & WISE workshop module has been created for students to engage with these virtual concepts. In these four-day, 90-minute sessions, middle school students will learn about engineering design processes, fundamental engineering and science concepts, and CAD software. They will create virtual mechanical components using CAD software, while hands-on tasks will enable the creation of mechanical assemblies using discrete components to demonstrate the functionality of gears and drivelines. To assess the student experience, a survey was created and submitted for IRB approval. The pandemic created a unique situation for these prepared sessions as students could not participate right away, however, they will be offered in the future

Investigation into current industrial practices relating to product lifecycle management in a multi-national manufacturing company

Product Lifecycle Management (PLM) systems have gained growing acceptance for managing all information relating to products throughout their full lifecycle, from idea conceptualisation through operations to servicing and disposal. This paper, through an in-depth exploratory study into a leading power generation manufacturing organisation, presents current PLM issues experienced by manufacturing companies, exploring three separate topics: 1) PLM, 2) Knowledge Management and Lessons Learnt and 3) Product Servicing and Maintenance. Following a review of published literature, results of the investigation are presented, analysing the responses of 17 employees interviewed. With respect to Product Development, it was found that information traceability is time consuming and change management requests take too long to complete. Results relating to knowledge management indicate that the Company operates a ‘who you know’ culture, but do aim to capture lessons learned on the manufacturing shop floor and assembly lines. Therefore, a prototype design is proposed to integrate the capturing of lessons learnt within the existing PLM system

PLM and early stages collaboration in interactive design, a case study in the glass industry

Product design activity is traditionally presented as a succession of four to six stages. In the early stages of design, during the search for concepts, multi-disciplinary teams are working together, sometimes on the fringe of the digital design chain. But it is during these stages, that most of the product development cost is committed. Therefore, collaboration should be emphasized, and PLM software should contribute to it strongly. This paper first defines the boundaries of the early stages of design. Then, we analyze designer collaboration in this stage and describe the knowledge necessary for efficient collaboration. Finally, we propose and test a concept for a tool to assist the early stages of design, to be integrated in a continuum with other existing digital design tools. A case study is presented in Verallia, specialized in the design and manufacturing of glassware

Accelerating the adoption of Industry 4.0 supporting technologies in manufacturing engineering courses

[EN] Universities are one of the fundamental actors to guarantee the dissemination of knowledge and the development of competences related to the Industry of the Future (IoF) or Industry 4.0. Computer Aided (CAX) and Product Lifecycle Management (PLM) technologies are key part in the IoF. With this aim, it was launch a project focused on Manufacturing and partially funded by La Fondation Dassault Systèmes. This communication presents a review on CAX-PLM training, four initiatives already in place in universities participating in the project, the project scope, the approach to integrate with the industrial context, the working method to consider different competence profiles and the development framework.The authors express their gratitude to the other project colleagues and to La Fondation Dassault Systèmes for its funding support.Ríos, J.; Mas, F.; Marcos, M.; Vila, C.; Ugarte, D.; Chevrot, T.

Model-based Approach for Product Requirement Representation and Generation in Product Lifecycle Management

The requirement specification is an official documentation activity, which is a collection of certain information to specify the product and its life-cycle activities in terms of functions, features, performance, constraints, production, maintenance, disposal process, etc. It contains mainly two phases; product requirement generation and representation. Appropriate criteria for the product design and further life-cycle activities are determined based on the requirement specification as well as the interrelations of product requirements with other life-cycle information such as; materials, manufacturing, working environments, finance, and regulations. The determination of these criteria is normally error-prone. It is difficult to identify and maintain the completeness and consistency of the requirement information across the product life-cycle. Product requirements are normally expressed in abstract and conceptual terms with document base representation which yields unstructured and heterogeneous information base and it is unsuitable for intelligent machine interpretations. Most of the time determination of the requirements and development of the requirement specification documents are performed by the designers/engineers based on their own experiences that might lead to incompleteness and inconsistency. This research work proposes a unique model-based product requirement representation and generation architecture to aid designers/engineers to specify product requirements across the product life-cycle. A requirement knowledge management architecture is developed to enhance the capabilities of the current Product Life-cycle Management (PLM) platforms in terms of product requirement representation and generation. After a systematic study on the categorization of product requirements, an ontological framework is developed for the specification of the requirements and related product life-cycle domain information. The ontological framework is embedded in an existing PLM system. A computational platform is developed and integrated into the PLM system for the intelligent machine processing of the product requirements and related information. This architecture supports product requirement representation in terms of the ontological framework and further information retrieval, inference, and requirement text generation activities

PLM in design and engineering education: International perspectives

Technological advances in the last decade have influenced changes in the design and engineering industries on a global scale. Lean and collaborative product development are approaches increasingly adopted by the industry and seen as the core of product lifecycle management. These trends have created the need for new skilled professionals, and universities should adapt their curricula in response. There is an increased need for academia to work with industry in order to meet these challenges. This article reports on the Parametric Technology Corporation Academic Research Symposium held in April 2011. The topics were centred around understanding the essence of product lifecycle management and its impact on design and engineering education. Furthermore, examples of implementing product lifecycle management and collaborative practices in higher education were presented from the United States and France. This article concludes with a discussion of the recommendations made at the symposium for the future development and support of key skills across university curricula
