Integriertes Bauteildatenmodell für Industrie 4.0 - Informationsträger für cyber-physische Produktionssysteme

Kurzfassung Der Technologiefortschritt durch Industrie 4.0 ermöglicht die Nutzung von Bauteilen als Informationsträger und deren Vernetzung mit cyber-physischen Produktionssystemen. In dem Beitrag wird der Ansatz für ein integriertes Bauteildatenmodell für den Wertschöpfungsprozess Produktion vorgestellt. Die Basis bildet der Theta-Ansatz zur Repräsentation von Bauteilen als cyber-physische Objekte. Zudem wird eine exemplarische Anwendung im Rahmen von cyber-physischen Produktionssystemen beschrieben.

Functional Shape Elements Integrating Design and Manufacturing Knowledge

In the aviation industry, engine components of different families, variants and versions are characterized by a high level of geometrical, functional and procedural similarities and offer a high potential for rationalization. The reuse of existing knowledge is enabled in product development by part families and features libraries. The classification, administration and retrieval of these parts and features are mainly based on geometric properties, while functional aspects are not considered sufficiently. Nevertheless, in engine design the functional attribute is crucial: Two geometry elements with a nearly identical shape may be applied for completely different functions. A flange serves for transmitting torque as well as for sealing against hot air. In this paper functional shape elements integrating knowledge from both design and manufacturing and the method for their definition are introduced and their application is presented exemplarily.

Virtual Validation of Automotive Measurement Services Based on JT (ISO 14306:2012)

In this paper a concept for the virtual validation of automotive measurement services based on JT (ISO 14306:2012) is introduced. Each physical measuring component has a digital representation, represented by a 3D JT model. These models contain all necessary information of the measurement process and are the basis for the application of physical sensors. The developed concept enables the consistent usage of JT models and the suitable integration of virtual engineering methods into measuring services, resulting in improved efficiency and interoperability. For the implementation, instead of a CAD system, the viewing software Teamcenter Lifecycle Visualization Mockup is used. This leads to cost savings by the reduction of license fees. The concept is validated based on two measuring projects, containing separate component models and a complete vehicle model.

Distributed Additive Manufacturing: Concept for the Application of JT (ISO 14306) as Downstream Process Format

Additive manufacturing is gaining new impetus due to decreasing costs for additive manufacturing machines and materials, and the continuous improvement of additive manufacturing technology itself. The integration of modern internet technologies paves the way for a globally distributed additive manufacturing, but recently used data formats fall short to offer consistent solutions to address current and future requirements for efficient distributed additive manufacturing. The integration of the standardized 3D data format JT (ISO 14306) in distributed additive manufacturing enables the deployment of additive manufacturing processes based on open standards with a suitable integration in established engineering applications. Different geometry representations, integration of meta data, harmonization with other standardized data formats like STEP and the prevalence in industry lead to the usage of one standardized 3D data format for all engineering downstream processes. In this paper, two approaches for the integration of JT based on automated conversion and JT based slicing and tool path generation are introduced and validated. The utilization of web services enables the controlling and monitoring of additive manufacturing processes on mobile devices, independent of the location, for an efficient collaboration on a global scale.Copyright
