    Transdisciplinary Engineering Design Education: Ontology for a Generic Product Design Process2018In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 70, p. 338-343Article in journal (Refereed)
    Abstract [en]

    Today’s highly integrated product development practices emphasize the need to transform the engineering education from disciplinary to transdisciplinary. This paper is based on the results of an empirical study designed to introduce a common transdisciplinary design process in engineering education. It aims to validate the hypothesis that engineering disciplines in education share a common engineering design process. It describes the methodology for the development of a Transdisciplinary Engineering Design Education Ontology (TEDEO) for eight major engineering disciplines. It proposes a high-level transdisciplinary engineering design process that consolidates a diverse array of engineering terms and concepts into a generalized model.

    Experimental and PFEM-simulations of residual stresses from turning tests of a cylindrical Ti-6Al-4V shaft2018In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 71, p. 144-149Article in journal (Refereed)
    Abstract [en]

    Alloy Ti-6Al-4V is a frequently used material in aero space applications due the high strength and low weight. This material is however often considered as a difficult to machine alloy due to several material properties such as the inherent characteristics of high hot hardness and strength which is causing an increased deformation of the cutting tool during machining. The thermal properties also cause a low thermal diffusion from locally high temperatures in the cutting zone that allows for reaction to the tool material resulting in increased tool wear.

    Predicting the behavior of machining of this alloy is therefore essential when selecting machining tools or machining strategies. If the surface integrity is predicted, the influence of different machining parameters could be studied using Particle Finite Element (PFEM)-simulations. In this investigation the influence from cutting speed and feed during turning on the residual stresses has been measured using x-ray diffraction and compared to PFEM-simulations.

    The results showed that cutting speed and feed have great impact on the residual stress state. The measured cutting force showed a strong correlation especially to the cutting feed. The microstructure, observed in SEM, showed highly deformed grains at the surface from the impact of the turning operation and the full width half maximum from the XDR measurements distinguish a clear impact from different cutting speed and feed which differed most for the higher feed rate.

    The experimental measurements of the residual stresses and the PFEM simulations did however not correlate. The surface stresses as well as the sign of the residuals stresses differed which might be due to the material model used and the assumption of using a Coulomb friction model that might not represent the cutting conditions in the investigated case.

    Context Driven Remaining Useful Life Estimation2014In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 22, p. 181-185Article in journal (Refereed)
    Abstract [en]

    In the context of maintenance activities maintainers rely on machine information, their past breakdowns, adequate repair methods and guidelines as well as new research results in the area. They usually get access to information and knowledge by using information systems (nondestructive testing (NDT) or condition monitoring.), local databases, e-resources or traditional print media. Basically it can be assumed that, the amount of available information affects the quality of maintenance decision making and acting positively. Machine health information retrieval is the application of information retrieval concepts and techniques to the operation and maintenance domain. Retrieving Contextual information, describing the operational conditions for the machine, is a subarea of information retrieval that incorporates context features in the search process towards its improvement. Both areas have been gaining interest from the research community in order to perform more accurate prognostics according to specific scenarios and happening circumstances. Context is a broad term and in this paper the operational conditions and the way the machine has been used is seen as the context and is represented by operational data collected over time. This paper intends to investigate the effects of the interaction of context features on machine tools health information. This interaction between context and health assessment is bidirectional in the sense that health information seeking behavior can also be used to predict context features that can be used, without disturbing the operational environment and creating production disruptions.The extraction of multiple features from multiple sensors, already deployed in this type of machinery, may constitute snapshots of the current health of certain machine components. The mutation status (the way they have changed) of these snapshots, hereafter called Fingerprints, has been proposed as prognostic marker in machine tools problems. Of them, in this work so far only the spindle fingerprint mutation has been validated independently as prognostic for overall survival and survival after relapse, while the prognostic value of rest of components mutation is still under validation. In this scenario, the prognostic value of spindle fingerprint mutations can be investigated in various contexts defined by stratifications of the machine population.

    A Decision Support Tool for Optimising Support Site Configuration of Functional Products: Special Session: Product Development for Through-Life Engineering Services2014In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 22, p. 175-180Article in journal (Refereed)
    Abstract [en]

    The customization of the support site configuration (including the number, locations and capabilities of sites where maintenance staff are based) is of critical importance to functional product providers, who must provide maintenance support services for products operated by their customers at different locations and ensure that contractual guarantees for functional availability are met whilst keeping support costs under control. Since contract fulfilment costs are performance based and long term, they are difficult to predict without modelling. This paper discusses a decision support tool designed for use by management and engineering personnel at Functional Product providers to analyse and optimize the performance of their support base configuration. It features a graphical user interface for configuration customization, simulation modelling to predict performance and outputs a wide range of analytics that can be used to compare and optimize configurations. The tool is demonstrated via application to an industrial test case

    Integrating Use Phase Information and Virtual Product Representation to Support Functional Products2015In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 38, p. 204-209Article in journal (Refereed)
    Abstract [en]

    Providing not only products but a combination of products and services can help add value and enable competitiveness for both the providers and their customers. Research has suggested Functional Products (FP) as one concept to achieving this combination of products and services.Traditionally, when a product is sold the ownership of the product is transferred to the customer, making it difficult for the provider to access information from the products use phase. In the case of FP, the ownership of the product is retained by the provider, and access to use phase information is essential to provide the function at a guaranteed level of availability. This information access also allows feedback to earlier life cycle phases. This paper explores how information generated in the use phase of FP can be integrated with the virtual product representation in a Product Lifecycle Management (PLM) system.A concept was developed for capturing use phase information from a potential FP. The concept utilizes wireless sensors that makes the information available through networks. WebSockets are used for providing real-time access and visualisation of the information. Both real-time and historical information can be accessed in a dashboard by any device that supports HTML5. A PLM system connects relevant information from the FP in use with the virtual representation of the FP.The concept was implemented in a case at a producer of automotive parts. A unified solution for information management of both use and development of FP was achieved by integrating use phase information and the virtual product representation

    Development of a research vehicle platform to improve productivity and value-extraction in forestry2015In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 38, p. 68-73Article in journal (Refereed)
    Abstract [en]

    In spite of the high level of mechanization in most forestry operations there is a continuedneed for improvements in productivity and cost effectiveness. Automation of mechanised operations isone possible solution to achieve such improvements but new techniques that can acquire informationfrom the surroundings and make proper analyses rendering in streamlined or new work proceduresare prerequisites. Furthermore, product producers buying forest biomaterials often have certainquality wishes. As an addition to automatic work procedures, new technology can further be used toretrieve information for identification and selection of certain tree assortments with differentbiomaterial properties. In this way, performance-based delivery of tree biomaterial extracted withhighly automated work procedures has the possibility to be an enabler to continue the productivitydevelopment progress in the forest sector. The objective for this paper is therefore to summarizepossible technical needs for and to design an experimental research vehicle platform for academia andmachine developers to test and validate new solutions that could improve cost effectiveness inforestry. The platform is designed specifically to test and validate various control systems forautonomy and robotics and also to enable tests and validation of attachments, e.g. to enable betterplanting procedures or identification of trees with certain properties. Sensors are embedded in theplatform to register angles, rotation speed, etc., thus actualising machine automation as an enabler forperformance-based delivery of planting or of tree biomaterial assortments.

    Improving Functional Product availability: software-related measures planned and taken2017In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 59, p. 202-207Article in journal (Refereed)
    Abstract [en]

    The paper, based on an empirical study involving five companies, concerns software-related measures that are planned and taken by providers together with their customers to improve the availability of Functional Products (FP) or similar offers. The manufacturing industry is showing an increasing interest in adding offerings based on additionally complex business models, as opposed to merely offering products and services. This supports innovation and helps companies to stay competitive and profitable. Considerable focus is placed on performance- or result-based business models. Functional Products (FP) is one such business model, where the provider offers a function to customers at an agreed-upon level of availability, productivity or efficiency. FP comprise four main constituents: hardware, software, service-support system and management of operation, which together deliver value to customers on a long-term basis. The paper highlights nine software-related availability measures planned and taken by manufacturing companies and proposes additional potential software-related availability measures.

    When moving from products and services towards Functional Products: Which sustainability-oriented customer values are of interest?2016In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 48, p. 16-21Article in journal (Refereed)
    Abstract [en]

    The paper concerns which sustainability-oriented Functional Products (FP) customer values companies, who also provide products and services, consider as important to communicate to customers when offering or planning to offer FP. Currently, the manufacturing industry is showing increasing interest in adding offerings based on additionally complex business models as opposed to merely offering products and services. This is considered necessary if companies are to continue to be able to innovate and stay competitive and profitable in global competition. A considerable focus is directed towards performance- or result-based business models. FP is one such business model, where the provider offers a function to customers at an agreed-upon level of availability, productivity or efficiency. FP comprise the following four main constituents: hardware, software, service support system and management of operation, which together deliver value to customers on a long-term basis. The paper proposes a set of FP sustainability-oriented customer values which are categorized according to the sustainability aspects: economic, ecological and societal, and the set is further analyzed from a regulatory and legal perspective

    Cybersecurity level in IPS2: A case study of two industrial internet-based SME offerings2018In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 73, p. 222-227Article in journal (Refereed)
    Abstract [en]

    n a case study comprising two SMEs offering Industrial Product-Service Systems (IPS2) based on the industrial internet the paper addresses the current cybersecurity level of the two SMEs and the perceived need for added cybersecurity features. Cybersecurity is of crucial importance for most IPS2-offerings if they involve data communications, data collection and storage, and are also part of the customers’ critical processes (i.e., the core processes that always need to work with a high level of availability). The case study reveals that both IPS2-offerings have a basic level of core security spanning IoT-devices, IoT-networks, cloud services and users as well as administrators. Further, of interest is that the SMEs would like to add security cloud services with advanced security functionality in order to achieve scalability and efficiency regarding security- and general management as well as lifecycle management functionality. However, most of the security cloud services are mainly aimed at larger companies and not adapted for SMEs in terms of required knowledge, time and effort required to keep the security configurations up-to-date.

    Optimizing recycling management using industrial internet supporting circular economy: a case study of an emerging IPS22017In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 64, p. 55-60Article in journal (Refereed)
    Abstract [en]

    The paper concerns a case study about optimizing recycling management in terms of emptying containers holding, for instance, glass, paper, plastics or metal waste collected, thus supporting sustainability of natural resources and the circular economy. The case has been followed from the very start all the way to the current transformation into an IPS2 sold on a subscription basis. The main results of the case study suggest that the provider side must change considerably in terms of the business and organizational set-up, which has been challenging compared to the necessary, though more easily implemented, technological changes. Further, the IPS2 customers foresee improved efficiency and a decrease in unnecessary work if containers are emptied on time. In addition, the core of the IPS2 seems generalizable and transferable to other applications where collection and analysis of data are needed to support decision-making.

    Towards intelligent and sustainable production: combining and integrating online predictive maintenance and continuous quality control2017In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 63, p. 443-448Article in journal (Refereed)
    Abstract [en]

    The paper addresses intelligent and sustainable production in the sense of combining and integrating online predictive maintenance andcontinuous quality control. The rationale for combining and integrating them is that continuous quality control can provide input to the onlinepredictive maintenance in cases where no signs of maintenance issues have been indicated and inadequate output is produced (and the processparameters cannot be adjusted in order to meet the output specifications). The paper outlines the first part of an action research effort atGestamp HardTech AB in Sweden, whose objective is to keep its position as a world-leading provider of press-hardened vehicle parts. The firstinitial design criteria concerned with simplicity and low-cost was changed after learning more details and what can be accomplished, and theupdated first design criteria focused instead on robustness, high-quality output and future-proofing. The intermediary result is an action plan forthe technical change, whereas the organizational change will be addressed later during the action research effort.

    Functional Products business model elements: five industrial cases mapped to Hill categories2016In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 47, p. 513-518Article in journal (Refereed)
    Abstract [en]

    The paper addresses the Functional Products business model and how its elements are mapped to Hill categories in five industrial cases. The Hill categories include: order-winners, order-losers and qualifiers. The objective for Functional Products is to provide a function to customers with an agreed-upon level of availability, productivity or efficiency, etc. The paper outlines how different cases and their offers, based upon the Functional Products business model, can be element-wise mapped to Hill categories. Insight into the importance of the different business model elements provides valuable knowledge for an appropriate planning, design, sales and provision of Functional Products, as well as for determining how much effort, resources and money to spend on keeping the status of the element sharp, up-to-date, acceptable or just present.

    Sustainable management of operation for Functional Products: Which customer values are of interest for marketing and sales?2015In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 30, p. 299-304Article in journal (Refereed)
    Abstract [en]

    The paper addresses which customer values, related to sustainable management of operation for Functional Products, are of interest during manufacturing companies’ marketing and sales processes. Based on an empirical study covering five manufacturing companies, a set of customer values, which are categorized using Hill's [28] framework in order to understand whether they are important and why,is proposed. The analysis has generated a set of twenty-three potential values, whereof nine are considered as specific for contexts embodying Functional Products.Thus, the findings identify critical values to considerprior to, andwhen, selling Functional Products.

    A Survey Study of the Transitioning towards High-Value Industrial Product-Services2014In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 16, p. 176-180Article in journal (Refereed)
    Abstract [en]

    Servitization literature suggests that traditional manufacturing companies are increasingly offering industrial services in order to increase their position in the global competition. However, little is known about extent and profit potential of different types of such offers in current industry. This paper offers an overview of such offers and concludes that maintenance based business models are most closely linked to increased revenue generation while add-on services have a negative effect. Future trends, suggest that business models such as R&D services and functional services will be increasingly important in the future.

    Win-Win collaboration, functional product challenges and value-chain delivery: An explorative case study approach2013In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 11, p. 86-91Article in journal (Refereed)
    Abstract [en]

    Functional products (FPs) comprises of integrated hardware, software, and a service support system components that are bundled together to offer higher customer value and possibility to generate revenue. However, offering FPs requires forming and managing win-win collaboration with diverse global value chain partners. Based on twenty explorative interviews at two Swedish manufacturing companies, we specifically focus on the collaboration between FP provider and its value-chain delivery organizations. Our results show that such collaborations can lead to win-lose or lose-win situations. Furthermore, we identify six diverse relational challenges which could negatively influence the collaboration between FP providers and its value-chain delivery organizations

    Simulation-driven mobility function development2013In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 11, p. 157-162Article in journal (Refereed)
    Abstract [en]

    A trend among industrial companies is to change business strategies from hardware-oriented to more service-oriented solutions, e.g. functional product business models. In this paper, a mobility function scenario is developed and the objective is to derive a simulation-driven methodology for development of sustainable mobility functions. It can be concluded that mobility function solutions may create incitements for sustainability. When developing mobility functions, a lot of new requirements, brought about by increased product complexity, need to be managed by the simulation methodology. However, the proposed simulation strategy can be used to drive mobility function development.

    Challenges and opportunities within simulation-driven functional product development and operation: Special Session: Product Development for Through-Life Engineering Services2014In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 22, p. 169-174Article in journal (Refereed)
    Abstract [en]

    The product development process at industrial companies has traditionally focused on hardware-oriented solutions. Business strategies strive towards more service-oriented solutions e.g., functional product business models. In this paper two case studies are developed and the objective is to highlight important challenges and opportunities by implementing a simulation-driven strategy in functional product development and operation. It can be concluded that challenges and opportunities within simulation-driven functional product development and operation are related to both quality and management of the simulations. With the proposed strategies for validation and coupling of the simulations, some of the challenges within functional product development can be overcome.

    Applying action design research (ADR) to develop concept generation and selection methods2016In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 50, p. 222-227Article in journal (Refereed)
    Abstract [en]

    During conceptual design, concept generation and selection methods can be used to facilitate the generation of new ideas and the selection of the most promising suggestions. The present paper is an effort to understand better how action design research can be utilized to develop such methods. Using action design research, methods were developed through iterative cycles of building, testing and evaluation in the context of a deregulated railway market, through a close collaboration between actors from industry, a government agency and academia. The approach was found to be feasible and to provide generalization of the context-specific findings through the formulation of design principles.

    Service support system modelling language for simulation-driven development of functional products2013In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 11, p. 420-424Article in journal (Refereed)
    Abstract [en]

    A functional product (FP) comprises of an integrated package of hardware and support services sold under a performance-based contract. A barrier to the adoption of FP is the lack of tools for obtaining predictions of availability and support costs during product development. A previous paper by the authors described a simulation-driven development strategy for designing FP that are optimised for functional availability and support costs. This iterative strategy involves representing the FP design in a modelling language; using a software code to automatically generate and analyse a simulation model from this representation to produce detailed performance predictions; and using these predictions as feedback to improve the design. The use of a modelling language facilitates the representation of the design details within the hardware and support system that influence availability and support costs. This includes the maintenance process design, maintenance strategy design and maintenance resource availability design. In this paper, an overview of a modelling language the authors have developed for this purpose is described.

    Implementing Sustainable Product–Service Systems Utilizing Business Model Activities2017In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 64, p. 61-66Article in journal (Refereed)
    Abstract [en]

    To stay competitive and comply with government legislation, many global manufacturing companies try to diminish their environmental impact and avoid commoditization of their products by offering sustainable product–service systems (PSS). Offering PSS successfully is highly challenging, however, and significant interfirm heterogeneity exists with regard to successful PSS provision. Based on multiple case studies in two global manufacturing companies, the importance of the business model as an organizing device to align and coordinate key activities and scarce resources in PSS is highlight. The analysis provides insights into the underlying building blocks that will help firms implement a PSS business model and provides new implications for analyzing and improving PSS offers.

    Risks for Functional Products: Empirical Insights from two Swedish Manufacturing Companies2013In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 11, p. 340-345Article in journal (Refereed)
    Abstract [en]

    Manufacturing companies are increasingly offering add-on services and functional products (FPs) to secure their future competitiveness. For product oriented organizations, this represents a significant transition in their business models, leading to several risks and uncertainties. In this study, we attempt to identify and understand these potential risks that can hinder manufacturing companies from offering FPs. To reach the stated purpose, we have adopted a quantitative research approach and undertaken eighteen explorative interviews in two large Swedish manufacturing companies. Our results show ten potential risks that can negatively affect manufacturing companies. For example, contractual risks, breakdown or technical risk and inappropriate organizational structural risk were found to be the most prominent risks for FPs. These risks are categorized into three specific dimensions related to business models, namely value creation, value delivery and value capture. Thus, the study provides critical understanding towards how manufacturing companies can be better prepared for transforming into a successful FP provider through mitigating of identified FP risks.

    Functional Product Business Models: A Review of the Literature and Identification of Operational Tactical Practices2014In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 22, p. 157-162Article in journal (Refereed)
    Abstract [en]

    Offering functional products (FP) are beginning to emerge as a growing trend within industrial firms driven by the desire to achieve economic performance and sustainable resource management goals. Nevertheless, our knowledge about how companies can adopt and implement FP has remained limited. In this study, we conduct a systematic literature review related to FP business models and tactical practices to advance the understanding regarding FP implementation. Based on the in-depth analysis of 48 articles, we develop a framework that proposes a link between FP business models and tactics. We further link FP business models to five operational level tactics, which can ensure the degree of their implementation and value generation. The identified tactical sets are contract, marketing, network, product design, and sustainability aspects.

    Dislocation Density Based Material Model Applied in PFEM-simulation of Metal Cutting2017In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 58, p. 193-197Article in journal (Refereed)
    Abstract [en]

    Metal cutting is one of the most common metal-shaping processes. In this process, specified geometrical and surface properties are obtained through the break-up and removal of material by a cutting edge into a chip. The chip formation is associated with large strains, high strain rates and locally high temperatures due to adiabatic heating. These phenomena together with numerical complications make modeling of metal cutting challenging. Material models, which are crucial in metal-cutting simulations, are usually calibrated against data from material testing. Nevertheless, the magnitudes of strains and strain rates involved in metal cutting are several orders of magnitude higher than those generated from conventional material testing. Therefore, a highly desirable feature is a material model that can be extrapolated outside the calibration range. In this study, a physically based plasticity model based on dislocation density and vacancy concentration is used to simulate orthogonal metal cutting of AISI 316L. The material model is implemented into an in-house particle finite-element method software. Numerical simulations are in agreement with experimental results for different cutting speed and feed.

    Toward an improved strategy for Functional Product development by predicting environmental and economic sustainability2017In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 59, p. 208-213Article in journal (Refereed)
    Abstract [en]

    Functional Product (FP) has emerged as a business concept aimed at offering a function or performance, mainly in business-to- business applications, on an agreed upon level of availability and cost as well as at providing incitements towards a sustainable growth. Today the literature expanded into various specific approaches and IT solutions measuring sustainability. However, the literature lacks such approaches within the FP context. This explorative paper proposes on a conceptual level a strategy to predict a sustainability impact of an FP in terms of environmental and economic sustainability and optimize the FP configuration. This strategy is based on scenario modelling and simulation -driven approach. The practical significance of the proposed strategy lies in its implication to avoid costly “trial and error” method performed in the real world and to enable the development of more sustainable products. Through the proposed strategy, it is foreseen that sustainability impact can be quantified and minimised during the FP system development.

    Advancing Development of Product-Service Systems Using Ideas from Functional Product Development2014In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 21, p. 242-246Article in journal (Refereed)
    Abstract [en]

    In existing literature concerning integrated product-service (IPS) offers within manufacturing industry there are various closely related business concepts covering the shift from offering only physical artifacts (e.g. material goods, hardware) towards provision of integrated products and services, as well as further advanced offers. It has been observed that manufacturing companies offering, for instance, Product-Service Systems (PSS) face certain challenges during the development process. Further, research regarding Functional Products (FP) has developed ideas and methods that are also applicable to the PSS development process. FP and PSS are, depending on the level of complexity, often developed and later operated by regional or global provider consortiums. This paper, based on a literature review, highlights unsolved challenges in the development of PSS offerings and further proposes how ideas and methods from FP development (FPD) may resolve some of those challenges. Thus, ideas from FPD may advance the development of PSS, as well as other IPS offerings, towards being additionally robust and innovative, though also more complex.

    Powder particle attachment mechanisms onto liquid material2018In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 74, p. 140-143Article in journal (Refereed)
    Abstract [en]

    In order to achieve high powder and energy efficiencies of Direct Metal Deposition processes knowledge about the basic effects of the interaction of the particle on the liquid surface is mandatory. Characteristic zones on the melt pool surface were identified in high-speed images. In the melt pool area around the center of the laser beam illumination, particles immediately enter into the melt pool while in its vicinity the particles float on the melt pool until they incorporate. Closer to the solidification line, particles rest on the liquid surface and remain as surface roughness on the track after solidification.

    Welding of Non-nominal Geometries: Physical Tests2016In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 43, p. 136-141Article in journal (Refereed)
    Abstract [en]

    The geometrical quality of a welded assembly is to some extent depending part positions before welding. Here, a design of experiment is set up in order to investigate this relation using physical tests in a controlled environment. Based on the experimental results it can be concluded that the influence of part position before welding is significant for geometrical deviation after welding. Furthermore, a working procedure for a completely virtual geometry assurance process for welded assemblies is outlined. In this process, part variations, assembly fixture variations and welding induced variations are important inputs when predicting the capability of the final assembly.
