System- und Schnittstellenbeherrschung, Ideen- und Innovationsmanagement sowie die virtuell integrierte Produkt- und Prozessplanung sind zu entwickelnde Kompetenzen, die der veränderten Rolle des Menschen in der Industrie 4.0 Rechnung tragen. Dezidiert adressiert werden können diese in zukunftsweisend ausgerüsteten Lernfabriken.
The automotive industry faces three major challenges – shortage of fossil fuels, politics of global warming and rising competition from new markets. In order to remain competitive companies have to develop more efficient and alternative fuel vehicles that meet the individual requirements of the customers. Functional Integration combined with new Technologies and materials are the key to stable success in this industry. The sustaining upward trend to system innovations within the last ten years confirms this. The development of complex products like automobiles claim skills of various disciplines e.g. engineering, chemistry. Furthermore, these skills are spread all over the supply chain. Hence the only way to stay successful in the automotive industry is cooperation and collaborative innovation. Interdisciplinary and interorganizational development has high demands on cooperation models especially in the automotive industry. In this case study cooperation models are analyzed and evaluated according to their applicability to interdisciplinary, interorganizational development projects in the automotive industry. Following, the research campus ARENA2036 is analyzed. ARENA2036 is an interdisciplinary, interorganizational development project housing automobile manufacturers, suppliers, research establishments and university institutes. Finally, based on interviews with the partners and the precede analyses of cooperation models, suggestions for implementation are given to ARENA2036.
The powder coating of wood products as an emerging environmentally sustainable coating technology holds promise in terms of novel product quality features for engineered wood like medium-density fiberboards (MDFs). However, one major limitation currently impeding widespread application of powder coating technology is the availability of MDF panels that are suitable for this process. Typically, special-grade MDF panels are required that are more costly than standard-grade MDF panels to provide reliable coating quality, which makes powder coating economically unattractive for many users. Methods are needed that allow extending the range of available MDF grades. In the present study, three surface pretreatment approaches for MDFs were studied to increase the processability of standard-grade MDF in the powder coating process: atmospheric plasma pretreatment, infrared irradiation, and moisture equilibration in a climate chamber prior to electrostatic powder application. While atmospheric plasma treatment had no beneficial effect on the use of standard-grade MDF panels, both infrared preheating and preconditioning of the panels under controlled temperature–humidity conditions demonstrated that the range of MDF panels suitable for powder coating can be significantly extended by appropriate selection of the pretreatment procedure.
Die Bereitstellung der für einen Zerspanungsvorgang relevanten Werkzeugdaten ist heute selbstverständlicher Bestandteil integrierter Fertigungssysteme. Die für die Herstellung und das Nachschärfen der eingesetzten Zerspanungswerkzeuge notwendigen Informationen bleiben dabei allerdings bisher unberücksichtigt. Diese Lücke will eine VDI-Arbeitsgruppe schließen. Das Ergebnis wird in Form einer offenen Datenschnittstelle auf der bevorstehenden Grindtec 2014 präsentiert.
Hardboards (HBs) (wet-process high-density fibreboards) were made in an industrial trial using a binder system consisting of cationic mimosa tannin and laccase or just cationic tannin without any thermosetting adhesive. The boards displayed superior mechanical strength compared to reference boards made with phenol–formaldehyde, easily exceeding the European standards for general-purpose HBs. The thickness swell of most of the boards was slightly greater than the standards would allow, so some optimisation is required in this area. The improved board properties appear to be mainly associated with ionic interactions involving quaternary amino groups in cationic tannin and negatively charged wood fibres rather than to cross-linking of fibres via laccase-assisted formation and coupling of radicals in tannin and fibre lignin.
