The Role of re-design for Additive Manufacturing on the Process Environmental Performance
2018
Abstract At present, economic and technological design criteria for products and processes should be matched with the minimization of environmental impact objectives. Manufacturing, material production, and product design are strictly connected stages. The choice of a production system over another could result in significant material and energy/resource savings, particularly if the component has been properly designed for manufacturing. In this scenario, Additive Manufacturing, which has been identified as a potential disruptive technology, gained an increasing interest for the creation of complex metal parts. The paper focuses on the tools, based on the holistic modelling of additive and …
An Inverse Approach for the Design of the Optimal Preform Shape in Cold Forging
1998
Abstract In closed die forging the preform design plays a critical role for the success of the process: in fact it must ensure that in the finishing step the desired product is obtained without shape defects such as underfilling or folding and with a minimum material loss into the flash. In the paper an inverse approach is applied to the preform shape optimization problem: the method permits to evaluate a response function which links the set of parameters defining the preform shape with the fulfillment of the product design specifications. The proposed approach has been applied to a closed die forging process aimed to the production of a C-shape component, and has allowed to determine the …
VirDe: A new virtual reality design approach
2008
Virtual reality (VR), even if it does not represent any more a novel technology, is one of the most powerful tool to help designers during the development of new projects. This is proved by very numerous research activities related to this field. In this research, we have studied a new way to approach the development of a product. We present the ongoing development of a system, called VirDe, acronym of virtual design, which can allow the designers to perform the whole design process, from the modelling phase to the finite element method (FEM) simulation analysis, in a virtual reality environment. This new method allows remarkable time and money saving in the overall product design process, …
Product lifecycle management support: a challenge in supporting product design and manufacturing in a networked economy
2005
In this paper, we provide an overview of the changing design and manufacturing landscape in the 21st century that has come about because of IT and the changing global conditions. Based on this overview and a review of the current state of IT for PLM support in the design and manufacturing sector, we identify the areas of need for standards. A review of areas covered by standards leads us to the development of an initial typology of standards and a potential path for bringing convergence of these standards in support of PLM. We make a case throughout the paper that given the nature of the task we need to aspire to create open standards with wide participation. We conclude by arguing that the…
An integrated approach to the design of tube hydroforming processes: artificial intelligence, numerical analysis and experimental investigation
2004
In the last years, the growing role of process flexibility in modern mechanical industries has driven a rising interest in optimisation of process/product design through innovative techniques. Moreover, the development of niche productions, which are characterised by low production volumes and small batches leads to the need of more flexible and rapid forming technologies. In this way, a great research effort is performed towards the study of new stamping processes: among them hydro forming finds a large interest in automotive industry since it allows to significantly reduce tooling costs and also to avoid some secondary operations. Different studies are available in the technical literatur…
Critical success factors and criteria in the purchasing process A case study of a development project in Uganda
2015
Masteroppgave industriell økonomi og teknologiledelse- Universitetet i Agder, 2015 The research concerns how critical factors influence the procurement process to assure available equipment in the project. The case studied, Distance Education Leapfrogging Project, is a development project at Makerere University in Uganda. The project’s procurement process is critical to achieve project success, due to delays of equipment needed and equipment delivered with wrong specifications. Hence, to ensure adequate equipment according to schedule and more likely achieve success in DELP, the research concerns how critical factors influence the procurement process in the project to achieve success. The r…
To Increase Employee Engagement in Lean Continuous Improvement A Case Study at Fibo-Trespo
2015
Masteroppgave industriell økonomi og teknologiledelse- Universitetet i Agder, 2015 Fibo-Trespo produces laminate bathroom panel and countertops, in their production facilities based in Lyngdal. The organization started their lean journey in 2007, which has led to increased revenue throughout the years to follow. Today the organization is recognized as one of the leading organization within lean. Fibo-Trespo has gone through extensive changes since 2007, and our research seeks to determine if these changes has anchored into the organization’s workforce. More specifically, our research takes a closer look at the organizations approach to lean continuous improvement, and the effect it has on t…
Waste in Design and Engineering
2015
Masteroppgave industriell økonomi og teknologiledelse- Universitetet i Agder, 2015 Issues and Purpose Predictability in design and engineering processes is a significant challenge. It is important to improve predictability since design and engineering processes affects the entire product life-cycle. Increased predictability can render these processes more effective, thus, it is vital to understand the mechanisms that might impact value-creation. This study is part of the Integrated Methodology for Project Management (INPRO) project, which aims to improve planning processes in the construction industry. Consequently, the objective of our study is to identify the mechanisms that may potential…
Risikobasert vedlikeholdsplanlegging og fornyelsesstrategi for høyspente luftlinjer i distribusjonsnettet
2015
Masteroppgave industriell økonomi og teknologiledelse- Universitetet i Agder, 2015 I de senere år har nettselskapene blitt presset til mer effektiv drift av nettet. Dette medfører at det stilles strengere krav til systematiske metoder og gode analyser for investering, drift og vedlikehold. Denne rapporten ser på mulighetene for å utvikle verktøy og metoder for å skaffe et bedre beslutnings-grunnlag ved fornyelsesvurdering av høyspente luftlinjer i distribusjonsnettet hos Agder Energi Nett. Forskerspørsmålet undersøker om det er hensiktsmessig å benytte risikobaserte metoder og kost-nytte-analyser for å forbedre vedlikeholdsplanlegging, samt videreutvikle fornyelses-vurderingsprosessen, som …
