Robert Allen, J J. Pellegrino, D Monk, E C. Teague, Dennis A. Swyt, Joseph Fu, Richard M. Silver, Theodore V. Vorburger, Bradley N. Damazo, Robert Russell, Thomas E. Wheatley, Keith A. Stouffer, Manfred Osti, David Wilmering, Richard L. Rhorer, Ram D. Sriram
This report describes the accomplishments of the Nanomanufacturing of Atom-based Dimensional Standards Project, which operated as part of the National Advanced Manufacturing Testbed (NAMT) a program formally operating from fiscal year (FY) 1996 to FY 2000

Standards for Collaborative Product Development

September 1, 2001
Author(s)
Ram D. Sriram
We are currently witnessing the emergence of an Internet-based engineering marketplace, where engineers, designers, and manufacturers from small and large companies are collaborating through the Internet to participate in RFQs (requests for quotes), create

Progress Towards an International Standard for Data Transfer in Rapid

August 1, 2001
Author(s)
Lalit Patil, D Dutta, Ram D. Sriram, Kevin W. Lyons, Amba D. Bhatt, Mike Pratt, M Allahabad
This paper discusses the informational requirements of rapid prototyping and layered manufacturing (RPLM). The study is motivated by the recent decision to embark on the development of a new Application Protocol for the international standard ISO 10303

The Role of Knowledge in Next-generation Product Development Systems

March 6, 2001
Author(s)
Simon Szykman, Ram D. Sriram, William Regli
Information technology has played an increasingly important role in engineering product development. Its influence over the past decade has been accelerating and its impact in the coming decade will undoubtedly be immense. This paper surveys several

A Decomposition-Based Approach to Layered Manufacturing

January 1, 2001
Author(s)
R Janardan, I Ilinkin, J Schwerdt, Miles E. Smid, J J. Majhi, Ram D. Sriram
This paper introduces a new approach for improving the performance and versatility of Layered Manufacturing (LM), which is an emerging technology that makes it possible to build physical prototypes of 3D parts directly from their CAD models using a

Information Modeling on Conceptual Design Integrated with Process Planning

November 1, 2000
Author(s)
Ram D. Sriram, Mike Pratt, Shaw C. Feng, Eugene Song
Information modeling is critical to the integration of conceptual design and process planning. An information model for conceptual design is provided in this paper. Conceptual design is a key activity in early product development. It determines product

Environmental Issues in Collaborative Design

September 1, 2000
Author(s)
Robert Allen, Ram D. Sriram
We report about environmental issues in collaborative design. Specifically, we present background and motivation for the need to design greener products. After defining the green design process, we demonstrate how that integrates with the typical product

Design Repositories: Next-Generation Engineering Design Databases

July 1, 2000
Author(s)
Simon Szykman, Christophe Bochenek, J Racz, Ram D. Sriram
Summary of the NIST Design Repository Project, revised with some additional content on representation of function in computer-based design, and using XML to describe function and taxonomies in computer-based design.

Representation of Heterogeneous Objects in ISO 10303 (STEP)

July 1, 2000
Author(s)
Lalit Patil, D Dutta, Amba D. Bhatt, Kevin K. Jurrens, Kevin W. Lyons, Mike Pratt, Ram D. Sriram
Solid modeling of objects forms an important task in design and manufacturing. Recent developments in the field of layered manufacturing have shown potential for the physical realization of heterogeneous (multi-material) objects. Thus, there is a need to

Representing an Artifact Transport System in a Design Repository: A Case Study

July 1, 2000
Author(s)
Robert Allen, Ram D. Sriram, Simon Szykman, Robert J. Fijol
We report on a case study representing the design essence of a prototype ultra-high vacuum artifact transport system (ATS) in an existing design repository (DR). Specifically, we represent engineering geometry, function and assosiated behavior, as well as

The Role of Standards in Innovation

July 1, 2000
Author(s)
Robert Allen, Ram D. Sriram
We review and explore the role of standards in innovation, with particular emphasis on the design and manufacturing processes. We begin by defining and classifying standards and by exploring their role and infrastructure in society. This is followed by a
