    New Automated Composite Manufacturing Process:: Is it possible to find a cost effective manufacturing method with the use of robotic equipment?2012In: Proceedings of the 5th International Swedish Production Symposium / [ed] Mats Björkman, 2012, p. 523-531Conference paper (Other academic)
    Abstract [en]

    The use of carbon composites has continuously increased in the commercial aircraft industry due to more challenging weight targets which is one way to handle the environmental requirements to lower the CO2 emissions. One aircraft structure component made at Saab Aerostructures is long and slender U-sections manufactured in carbon composites. The manufacturing is performed by manual layup of composite material. These U-sections are selected as an illustrative case in order to discuss possibilities for an automated manufacturing process with the aim to reduce cost. A literature review of different existing technologies have been performed and compared with the industrial front at Saab Aerostructures. Automated Tape Laying (ATL) and Automated Fibre Placement (AFP) are the two dominating automation methods, of today, for aircraft prepreg manufacturing. Both methods are heavy investments for small to medium size composite manufacturers. Analysis in the case has shown that the selected component cannot be automated with these two methods due to design constrains. The paper suggests that another automated method with a cutting machine in combination with an industrial robot with a vacuum gripper, is selected for further work. The proposed pick and place process is also assumed to reduce the material waste.

    Is Design Automation a Feasible Tool for Improving Efficiency in Production Planning and Manufacturing Processes?2018In: Proceedings of the 8th Swedish Production Symposium (SPS 2018), Elsevier, 2018, Vol. 25, p. 8p. 194-201Conference paper (Refereed)
    Abstract [en]

    The production planning is a repetitive process that demands engineering hours and expertise. Many parameters must be considered, and inefficiencies lead to increased lead times. The hypothesis is that valuable time within the manufacturing stages can be saved through improved engineering tools. This article will explore to possibilities to increase the utilization of digital tools to support the engineers in their production planning activities, and to improve the efficiency of manufacturing processes. Through study visits and interviews at a product owning company with manufacturing in-house, proposals for areas that could be improved with design automation will be presented.

    Cross-cultural communication challenges within international transfer of aircraft production2011In: Computer Supported Cooperative Work in Design (CSCWD), 2011, IEEE , 2011, p. 835-841Conference paper (Refereed)
    Abstract [en]

    The research within this paper identifies three main categories of cross-cultural communication challenges within international transfer of aircraft production. The first category is organizational structure, hierarchy and delegation of responsibility the second category is consensus behavior and avoidance of conflicts and the third category is individual motivation factors. Furthermore, the paper discusses the need for specific types of cross-cultural training that can be one solution for reducing the problems and difficulties that cultural challenges may induce. The case study indicates that it is important for Aeronautics, a Swedish enterprise, to apply organized cross-cultural training in combination with technical training. To secure the presence of cross-cultural training, suitable types of cultural training could be included in the working process/routine for how to conduct a production transfer.

    International transfer of aircraft production: Problems and effects due to cultural differences2011Conference paper (Other academic)
    Abstract [en]

    In transfer of advanced industrial production in connection with offset business may not the selling organization be free to choose the most suitable subcontractor with respect to culture, organization, technical level etc. This paper discusses in specific Aeronautics (one of five business areas at Saab Group) and identifies different complications that can occur when different cultures meet during the transfer of production processes. The research is based on a case study utilizing interviews, observations and literature studies. Compilation and analysis of gathered empirical data indicates that many of the differences that emerge during transfer of production technology from Aeronautics to subcontractors in other countries can be exemplified by: -differences in hierarchal organization between different cultures, Swedes’ consensus behaviour and avoidance of conflicts and differences in individual motivation factors between cultures. All of these are considered from the perspective of different categories of employees such as; operators, engineers and management. For a successful transfer of production, the case study implies that important factors are; harmonization of production documentation between receiver and sender, and education of project team on receiving company’s culture before the production transfer is started.

    Production Start-up Phase: A Comparison between New Product Development and Production Relocation2012Conference paper (Other academic)
    Abstract [en]

    A challenging situation due to a more global market is the increasing need for production relocation. New product development with constant increasing competition challenges the ways to perform production start-up and production relocation. Product development processes focus in general on function of the product and to avoid product quality problems. Production relocation processes also focus on avoiding product quality problems, but problems that occur within production relocation are mostly related to forgotten or misunderstood information. In this paper, a literature review is performed investigating these three areas and relate them to industrial experience. Existing relocation processes are often based on processes for product development. There are several similarities between the production start-up in product development and product relocation since the same result is requested. However, the way to achieve the results can differ within the literature, within the paper are the differences and similarities discussed.

    Bridging capability gaps in technology transfers within related offsets2016In: Journal of Manufacturing Technology Management, ISSN 1741-038X, E-ISSN 1758-7786, Vol. 27, no 5, p. 640-661Article in journal (Refereed)
    Abstract [en]

    Purpose – The purpose of this paper is to explore how capability gaps can be identified and how they can be dealt with in aircraft technology transfers in future offset deals.

    Methodology – The study is based on lessons learned as identified from three case studies of technology transfers from Saab, a Swedish aircraft manufacturing company to South Africa, the Czech Republic, and India.

    FindingsThe capability gap between sender and receiver has to be dealt with on two levels: on an organizational level; and on an individual level. It is proposed that the disseminative capacity constitutes the ability to assess the capability gap between the sender and receiver, and to convert this assessment to adaptations of the product and production process to include in an industrialization process. On the individual level, the capability-raising activities were connected to employees’ knowledge, Personal Development Plans for the transfer of explicit knowledge, as well as on-the-job training to facilitate the exchange of tacit knowledge.

    Research limitations The research is based on case studies from one company.

    Originality/value – The paper focuses on the context of offset and reports on actual experiences from a capability perspective of technology transfers within the aircraft manufacturing area. It proposes a structured way of identifying and bridging the capability gap within such transfers.

    Exchange of tacit knowledge within advanced production with small batch sizes2013In: Received wisdom, kernels of truth, and boundary conditions in organizational studies / [ed] Daniel J. Svyantek and Kevin Mahoney, Information Age Publishing, 2013Chapter in book (Other academic)
    Abstract [en]

    This volume of the Research in Organizational Sciences is entitled "Received Wisdom, Kernels of Truth, and Boundary Conditions in Organizational Studies". Received wisdom is knowledge imparted to people by others and is based on authority and tenacity as sources of human knowledge. Authority refers to the acceptance of knowledge as truth because of the position and credibility of the knowledge source. Tenacity refers to the continued presentation of a particular bit of information by a source until this bit of information is accepted as true by receivers. The problem for organizational studies, however, is that this received wisdom often becomes unquestioned assumptions which guide interpretation of the world and decisions made about the world. Received wisdom, therefore, may lead to organizational practices which provide little or no benefit to the organization and, potentially, negative organizational effects, because this received wisdom is no longer valid. The 14 papers in this volume all, in some way, strive to question received wisdom and present alternatives which expand our understanding of organizational behavior in some way. The chapters in this volume each strive to present new ways of understanding organizational constructs, and in so doing reveal how received wisdom has often led to confirmation bias in organizational science. The knowledge that some perceived truths are actually the products of received wisdom and do not stand up to close scrutiny shakes up things within research areas previously thought settled allowing new perspectives on organizational science to emerge

    Assembly cell concept for human and robot in cooperation2013In: 22nd International Conference on Production Research: Challenges for sustainable operations, 2013Conference paper (Refereed)
    Abstract [en]

    Today’s aerospace assembly is a huge manual task according to strictly controlled instructions, where differentoperators are responsible for different areas. This harmonizes with the overall lean approach, but the assemblyis very time-consuming and some tasks are not ergonomically friendly, such as assembly tasks inside a wingbox. Here, it could be possible to increase automation with the aim to facilitate a shorter assembly time andergonomically improved workplace. This paper will present different assembly cell concepts utilizing differentsafety strategies to achieve human-robot cooperation in an aerospace industry assembly line. These conceptswill be discussed in relation to a case in the aerospace industry. The paper concludes with suggestions forthree conceptual human-robot cooperation layouts. These are based on previous research in the areas ofsafety and human-robot cooperation, in combination with observations from an aerospace assembly line.

    On Safety Solutions in an Assembly HMI-Cell2015In: SAE Technical Papers, Warrendale, PA, USA: SAE International , 2015, p. Art.nr. 2015-01-2429-Conference paper (Refereed)
    Abstract [en]

    The increased diffusion of cooperation between humans and robotics in manufacturing systems is one of the next things to implement within robotics. Since the computer power gets more and more powerful, the possibilities increase to achieve safer working environment, due to that all safety signals demands fast management of data. This could lead to a possibility to work closer and more direct with a robot, using the robot as a third hand. Within an EU FW7 funded project called LOCOMACHs (Low Cost Manufacturing and Assembly of Composite and Hybrid Structures) there are one study focusing on how to support a future higher TRL-leveled HMI cell (Human Machine Interaction) in an assembly task. The main objective in this paper is to present how different external safety systems could support the whole HMI assembly cell to work properly in an industrial context. The scenario for HMI, in this case, is that an operator enters into the robot working area with the aim to perform an assembly task that need two hands. There are different support systems that could be applied to this assembly application, but every one of these needs to coincide with official standards to be applied in an approved industrial HMI assembly cell. The different safety support systems that are used in this research are light barriers, physical barriers and three-position enabler. These safety support systems are tested in a demonstrator assembly cell using a mock-up wing part. The tests with the selected safety support systems in the physical demonstrator will be compared with a concept that uses cameras to achieve the same degree of safety.

    Flexible automation in the printing industry2012In: Proceedings of the 5th International Swedish Production Symposium / [ed] Mats Björkman, 2012, p. 45-51Conference paper (Other academic)
    Abstract [en]

    The printing industry had a turnaround on about 700 billion US dollar in 2008. Althoughthe printing process itself is highly automated, a lot of the handling between process stepsis done manually and these heavy lifts could result in occupational injuries with long timeexposure. Operators for example can lift up to 1-2 tons/hour when moving large stacks ofpaper from a pallet to a jogger table before cutting. For quality reasons it’s important tomake these lifts with correct airing of the paper and without harming the edges or surface,something a human is very adapt in doing. To see if it is possible to do this mechanically,a dual armed robot equipped with grippers was used to lift an air paper stacks inlaboratory experiments. In order to achieve the same high quality as in manual handlingthese experiments tested the grippers, gripper fingers, robot movements and grippositions to find the best parameters for a future automated paper handling cell. The testsshowed that a dual armed robot could lift paper stacks with satisfying airing withoutharming the paper. Also, better gripper fingers were developed for lifting the paper withouttears or surface marks.
