Reconfigurable Machine Tool

Purpose In manufacturing, dedicated machine tools and flexible machine tools are failing to satisfy the ever-changing manufacturing demands of short life cycles and dynamic nature of products. These machines are limited when new product designs are introduced. The solution lies in developing responsive machines that can be adjusted or be changed functionally when these change requirements arise. These machines are reconfigurable machines which are becoming the new focus, as they rapidly respond to product variety and volume changes. A sheet metal working machine known as a reconfigurable guillotine shear and bending press machine (RGS&BPM) has been developed. The purpose of this paper is to present a methodology, function-oriented design approach (FODA), which was developed for the design of the RGS&BPM. Design/methodology/approach The design of the machine is based on the six principles of reconfigurable manufacturing systems (RMSs), namely, modularity, scalability integrability, convertibility, diagnosability and customisability. The methodology seeks to optimise the design process of the RGS&BPM through a design of modules that make up the machine, enable its conversion and reconfiguration. The FODA is focussed on function identification to select the operational function required. Two main functions are recognised for the machine, these being cutting and bending; hence, the design revolves around these two and reconfigurability. Findings The developed design methodology was tested in the design of a prototype for the reconfigurable guillotine shear and bending press machine. The prototype is currently being manufactured and will be subjected to functional tests once completed. This paper is being presented not only to present the methodology by to show and highlight its practical applicability, as the prototype manufacturers have been enthusiastic about this new approach. Research limitations/implications The research was limited to the design methodology for the RGS&BPM, the machine which has been designed to completion using this methodology, with prototype being manufactured. Practical implications This study presents critical steps and considerations in the development of reconfigurable machines. The main thrust being to explore the best possibility of developing the machines with dual functionality that will assist in availing the technology to manufacturer. As the machine has been development, the success of the design can be directly attributed to the FODA methodology, among other contributing factors. It also highlights the significance of the principles of RMS in reconfigurable machine design. Social implications The RGS&BM machine is an answer for the small-to-medium enterprises (SMEs), as the machine replaces two machines with one, and the methodology ensures its affordable design. It contributes immensely to the machine availability by eliminating trial and error approaches. Originality/value This study presents a new approach to the design of reconfigurable dual machines using principles of RMS. As the targeted market is the SME, it is not limited to that as any entrepreneur may use the machine to their advantage. The design methodology presented contributes to the body of knowledge in dual reconfigurable machine tool design.

Purpose The purpose of this paper is to clarify the concept of perceived risks, identify the main antecedents and outcomes of health risk perceptions and propose a conceptual model of health risk perceptions in tourism. Design/methodology/approach This paper provides a review of the literature on customer risk perceptions, along with their antecedents and outcomes, and proposes a conceptual model of health risk perceptions in tourism. Findings Key findings reveal that the main factors of health risk perceptions can be broadly classified into cognitive, affective, individual and contextual components. The proposed conceptual model of health risk perceptions provides a theoretically integrated overview of relationships between all groups of factors, tourists’ risk perceptions and travel intentions. Originality/value The paper contributes to theory by offering a new approach to health risk perceptions in tourism, which remain underexplored in previous studies. The literature review adds to the body of knowledge by introducing four main groups of factors affecting tourists’ health risk perceptions, while the conceptual model proposes relationships between these factors, tourists’ risk perceptions and travel intentions.

Purpose This study aims to introduce a new method for locating candidate substrates in part models and evaluating their feasibility. Design/methodology/approach Slices of an STL model along candidate directions are evaluated for the fitting of regular cylindrical and rectangular stock. Next, the part model is skeletonized and tested for collision assuming deposition growth of features from the candidate substrate. Findings The method is successfully able to find feasible substrates and conduct collision simulation for a variety of part models. Research limitations/implications The algorithm is limited to cylindrical and rectangular substrates and only considers collision between the substrate and the deposition head. Originality/value This method represents a new approach to solving a portion of the hybrid manufacturing process planning problem.

Purpose Neutrality is a much debated value in library and information science (LIS). The “neutrality debate” is characterised by opinionated discussions in contrasting contexts. The purpose of this paper is to fill a gap in the literature by bringing these conceptions together holistically, with potential to deepen understanding of LIS neutrality. Design/methodology/approach First, a literature review identified conceptions of neutrality reported in the LIS literature. Second, seven phenomenographic interviews with LIS professionals were conducted across three professional sectors. To maximise variation, each sector comprised at least one interview with a professional of five or fewer years’ experience and one with ten or more years’ experience. Third, conceptions from the literature and interviews were compared for similarities and disparities. Findings In four conceptions, each were found in the literature and interviews. In the literature, these were labelled: “favourable”, “tacit value”, “social institutions” and “value-laden profession”, whilst in interviews they were labelled: “core value”, “subservient”, “ambivalent”, and “hidden values”. The study’s main finding notes the “ambivalent” conception in interviews is not captured by a largely polarised literature, which oversimplifies neutrality’s complexity. To accommodate this complexity, it is suggested that future research should look to reconcile perceptions from either side of the “neutral non-neutral divide” through an inclusive normative framework. Originality/value This study’s value lies in its descriptive methodology, which brings LIS neutrality together in a holistic framework. This framework brings a contextual awareness to LIS neutrality lacking in previous research. This awareness has the potential to change the tone of the LIS neutrality debate.

Purpose The paper focused onto the development of microcapsules by using two essential oils. It proposes the uses of eucalyptus oil and cedarwood oil as a natural insecticide. The purpose of this paper is to demonstrate the application of developed microcapsules to impart insect repellency on textile substrate. Design/methodology/approach The paper opted for an experimental study using two essential oils and gum in formations of microcapsules through a simple coaseravtion encapsulation technique. The developed solution was analyzed, including confirmation of size and structure through. Application of developed finish on substrate was also undertaken to prove better ability as repellent fabric. Findings The paper highlights useful invention of microencapsulated fabric developed with the combination of gum acacia and eucalyptus oil as core and shell material. The developed fabric has better ability to repel silverfish as compared to microencapsulated fabric developed with gum acacia (shell) and cedarwood oil (core). Research limitations/implications Due to the lack of time and less availability of essential oils, only two oils were used to test the insect repellent behavior. Practical implications This paper fulfills an identified need, it includes implications for the development of a very useful natural insecticide to repel silverfish (Lepisma saccharina) insect. This insect is a very common problem found in cloth wardrobes and bookshelves; it mainly attacks the fabric with cellulosic content and starch. Social implications Society will get major benefit of using these microencapsulated finished fabrics, which repel silverfish from their home and keep their clothing and books safe for longer period. The natural fragrance and medicinal benefits of these essential oils can never be ignored. Originality/value This study sets a new approach to repel insects like silverfish from the bookshelves and clothing wardrobes. A layer of insect repellent microencapsulated finished fabric can be added in these shelves and wardrobes. It is an eco-friendly approach of using natural essential oils instead of chemical insecticides.

First Time

Purpose – Within team-oriented approaches, tasks are assigned to teams before being assigned to workstations as a reality of industry. So it becomes clear, which workers assemble which tasks. Design/methodology/approach – Team numbers of the assembly line can increase with the number of tasks, but at the same time, due to physical situations of the stations, there will be limitations of maximum working team numbers in a station. For this purpose, heuristic assembly line balancing (ALB) procedure is used and mathematical model is developed for the problem. Findings – Well-known assembly line test problems widely used in the literature are solved to indicate the effectiveness and applicability of the proposed approach in practice. Originality/value – This paper draws attention to ALB problem in which workers have been assigned to teams in advance due to the need for specialized skills or equipment on the line for the first time.

The Relationship

Purpose – The purpose of this paper is to provide insights into the relationship between dynamic capabilities and innovation capabilities. It links dynamic capability with innovation capability and indicates the ways they can be related. Design/methodology/approach – The relationships between dynamic and innovation capability were investigated through a systematic literature review. Findings – The review indicates that common characteristics exist between of the both fields, which demonstrate six relationships. Additionally, findings show some inconsistencies and even contradictions. Originality/value – In this paper, the authors have compared dynamic capabilities, a relatively new approach in the field of strategic management, with innovation capabilities, a widely recognised crucial domain for sustained competitiveness. Since both areas address issues that are essential to today's environment, future research should seek to clarify both concepts, by undertaking some new research and developing comprehensive and unambiguous framework.

Purpose ISO 9001 is applied by hundreds of thousands of companies throughout the world. For this reason, its effect on company results has been extensively studied. However, the results of those studies are inconclusive and sometimes contradictory. More in-depth research, with a new approach, is therefore necessary. The purpose of this paper is to analyse whether ISO 9001-certified companies suffered the effects of the financial and economic crisis of 2007–2008 to a lesser degree than non-certified ones. Design/methodology/approach A set of 179 companies certified by ISO 9001:2008 and 154 non-certified ones were analysed, as well as the accounting figures for net sales and operating income (EBIT: earnings before interest and taxes) from 2004 to 2012. Findings Companies from the industry and services sectors showed different results. Certified industrial companies achieved better outcomes than their non-certified counterparts. However, the deviations in outcomes were not significant for services companies. Research limitations/implications One limitation of this study is that companies’ official results are not always their true results. Another limitation is that having to do with the criteria followed to suppress extreme cases, which is always subjective. Furthermore, the implications of the results could be of use for those managers who are responsible for implementing ISO 9001 and for deciding whether obtaining the ISO 9001 certification would be beneficial to their companies. Originality/value This study constitutes a new approach for the assessment of the benefits of the ISO 9001 certification.

Purpose What happens when a librarian outgrows their maker learning location or transfers to a new library? The purpose of this study is to explore the planning process for second and/or new library makerspaces. Is the planning more intentional? Is there more focus on how the makerspace should be put together for the community served? Is the community further involved? This study will explore those questions and more. Design/methodology/approach Using content analysis, the perspectives of practicing librarians in the achievement of subsequent makerspaces are examined. Data include librarian interviews, an analysis using NVivo 11 through the lens of design thinking, and a final review using member checking by each research participant. Findings Makerspaces continue to grow in popularity in school and public/community libraries. What is unexplored is the moving from a first makerspace to the implementation of a second and/or new maker learning location. More intentional planning is involved. The community served by the library is further engaged in the planning. Study results illustrate the value that community insight and intentional planning play in the design and implementation of makerspaces. Originality/value Makerspaces in libraries continue to grow in popularity; in turn, the body of peer-reviewed, scholarly publications also continues to grow. Librarians in the field are beginning to move from their first to second makerspaces. This study investigates those perspectives. Much can be gained from the experiences of those who have implemented their second or third makerspace.

PurposeThe purpose of this paper is to identify human capital factors that pertain both to setting up and successfully running a business. To achieve this objective, the authors apply and extend the theory of career choice offered by Lazear (2005) that explains individual selection into entrepreneurship.Design/methodology/approachThe authors hypothesise that individuals with broader educational and professional backgrounds are more likely to start a business and are more likely to run a business in the long term. The authors tested the hypotheses using unique data from 800 current entrepreneurs, 800 employees who were previously entrepreneurs and 842 employees with no entrepreneurial experience, by means of a logit regression with robust standard errors and extensive robustness checks.FindingsThe authors empirically show that individuals with more diverse educational and professional backgrounds tend to have both greater chances of starting a company, as well as a higher probability of entrepreneurial success. Surprisingly, having managerial experience proved to exert a negative influence on the likelihood of starting a business while having an insignificant impact on the odds of entrepreneurial success.Research limitations/implicationsThe findings are informative for those planning or pursuing an entrepreneurial career, but they are also relevant for the purpose of entrepreneurship education.Originality/valueThe author's extend the body of research supporting Lazear's (2005) theory by showing that broad education and professional experience not only contribute to a higher propensity to start a company but they are also success factors in business per se.
