...Craig M. Shakarji; Vijay Srinivasan Recent advances in the digitization of manufacturing have prompted ASME and International Organization for Standardization (ISO) standards committees to reexamine the definition of datums. Any new definition of datums considered by the standards committees should...

... engineering data representations into AR systems without loss of context and information remains a challenge. A major barrier is the lack of interoperability between manufacturing-specific data models and AR-capable data representations. In response, we present a pipeline for porting standards-based design...

...Vijay Srinivasan; Lutz Lämmer; Steven Vettermann Recent developments in information technology are influencing the field of engineering informatics in some profound ways. Nowhere is the influence more evident than in the use of Internet-based technologies and standards to share engineering...

... optimization problems. The filtering problems can be unified under convolution problems, which include convolutions of functions as well as convolutions of sets. This paper presents the status of research and standardization efforts in computational metrology, with an emphasis on its classification...

... (CAPD) to the future fully integrated computer-aided product realization (CAPR) process. The categories of processes and the layers of information exchange are reviewed. The current practice in product information exchange, the relevant information exchange standards, and near-future plans...

...Volker Poenisch; Andrew Clark Software architectures for knowledge-based engineering often separate applications from their knowledge sources. We propose elements for a new standard for the resulting interface. The fully automatic transfer of knowledge would require a shared engineering ontology...

... that the proposed OAM will enhance the assembly information content in the STEP standard. A case study example is discussed to explain the Usecase analysis of the assembly model. An Assembly is a composition of its subassemblies and parts. A Part is the lowest level component. Each assembly component (whether...

... of data exchange standards in the aeronautics industry. It deals with the use of the STEP AP209 standard dedicated to the exchange of finite element analysis data. Applied in the context of Concurrent Engineering within the extended enterprise, the STEP AP209 standard should enhance the communication...

...Allison Barnard Feeney The first Technical Note in this series [1] introduced the international standard ISO 10303, informally known as STEP (STandard for the Exchange of Product model data). Subsequent Technical Notes discussed various issues faced by users of STEP and how the ISO TC184/SC4...

.... However, the sheer number of interconnections and the resulting complexity threaten to overwhelm the ability of the standards community or industry to provide the necessary specifications—a way out of this impasse must be found. This paper outlines the elements of an approach and the technology to move...

...Michael J. Pratt The first Technical Note in this series [1] introduced the international standard ISO 10303, informally known as STEP, and the second [2] dealt with some practical aspects of using the standard for the exchange of CAD models. It was noted in [1] that the current published parts...
