    Im November 2011 führten der Verein Deutscher Ingenieure (VDI), das Fraunhofer-Institut für Produktionsanlagen und Konstruktionstechnik (IPK) und CONTACT Software eine Online-Umfrage zum Thema Kollaborative Produktentwicklung und digitale Werkzeuge durch. Insgesamt beantworteten über 1.400 Ingenieure den Fragebogen und lieferten damit eine hervorragende statistische Basis für eine der auch international größten Erhebungen in diesem Umfeld in den letzten 10 Jahren. Die Bestandsaufnahme zeigt, wie Ingenieure ihre heutige Situation wahrnehmen, was vorrangige Anforderungen und Problemstellungen in der Zusammenarbeit mit anderen Abteilungen und Unternehmen sind und wo digitale Werkzeuge eine bessere Unterstützung als bisher leisten müssten. Ein zentrales Ergebnis ist, dass Teamwork, Partnernetzwerke und ein intensiver Datenaustausch den Arbeitsalltag von Ingenieuren dominieren. Dadurch bleibt ihnen immer weniger Zeit für ihre Kernaufgaben: Fast 2/3 der Befragten verwenden 20% und weniger ihrer Zeit für das Entwickeln, Konstruieren und Absichern von Produkten.

    Transformation towards an IPS2 business: A deployment approach for process-based PSS development projects

    Existing methods and tools developed in the frame of the IPS2 research are mainly concerned with general IPS2 and service design and are still very conceptional. Deployment approaches for those methods and tools for the use in practice are hard to find. This paper proposes a deployment approach for process-based IPS2 development projects in industry, which has been designed in the scope of a German project on IPS2 Engineering. This deployment approach proposes a systematic approach for manufacturers to deploy dedicated development methodology and process-based project management methods for IPS2 development.

    3D data acquisition technologies are increasingly used in the area of maintenance, repair and overhaul (MRO) of long-life technical systems and industrial plants. Application fields are measuring, reengineering and reproduction of disassembled parts. Fraunhofer IPK is developing a reverse engineering process for provision of 3D product models based on 3D scans of complete assemblies to save disassembly time and to support change management and reengineering tasks. This paper depicts results of IPK's data processing approaches for automated separation and identification of single parts in 3D assembly scans as well as for mapping of assembly structures in product data management systems. The major requirement was to automatically derive a product structure for assembly models as typically used in CAD or PDM systems. This structure can either consist of parts which were retrieved from a data base with solution element 2 or generated by conventional reverse engineering. To generate a contact graph for part relations in an assembly and its sub-assemblies a combination of different principles was realized in a software prototype and tested. This prototype loads the CAD parts of an assembly in one batch, before the user starts the structure generation process either fully automated or semi-automated by setting a threshold value for determining number of main assemblies of a product. Firstly, adjacent surfaces are identified by neighborhood analysis including contact surfaces and cutting volumes to derive a 2D contact graph. Secondly, the Girvan-Newman algorithm was applied to partition sub-graphs. Thirdly, a top down iteration for partitioning completed the product structure. Manual modification of structure nodes is possible in order to address a specific design intent or way of structuring the (sub-) assemblies. Finally, the CAD structure could be exported in an XML-based format for PDM data exchange. The file references all 3D models of the assembly's parts. For instance with SPLM Teamcenter, assembly import is possible with out-of-the-box functionality.

    This paper introduces a concept applied for a new PLM-supported process in steam turbine service business. The concept has been developed and instantiated in an industrial case: The paper starts with an analysis of engineering processes and the IT landscape in a globally acting company offering MRO (Maintenance, Repair and Overhaul) services for steam turbines. Illustrations show how digital product and service data is generated, edited, enriched, and managed throughout the lifecycle of a steam turbine. In order to enhance the already PLM-supported service process the concept for the new PLM process was defined within the company. The concept implements one single PDM system with interfaces to one dedicated ERP system. Illustrations of the new PLM process show how to manage product and ser vice documentation generated throughout the steam turbine lifecycle. The paper provides first-hand experiences made in a PLM migration project, which implemented the new PLM process.

    Today, product development is characterized by cross-company collaboration and an intensive exchange of product data. Engineers typically apply a multitude of digital engineering tools and act in diverse engineering processes. In a current study, the culture of todays collaborative product development was investigated in significant detail. The questions are: How do engineers work today? Which tasks play a major role in their daily business? How much time is remaining for core engineering tasks like design, calculation and design validation? How do engineers assess their workplace (environment)? Where are opportunities for enhancement of processes and digital engineering tools? In total, 1,401 engineers answered the questionnaires. Details of the study and selected findings are presente d in this paper. Interesting findings are related to collaborative engineering and engineering design, Product Data and Lifecycle Management (PDM/PLM), virtual product creation, information and process management, and new media in engineering design.
