Assembly Model Representation from Conceptual to the Detailed Design

March 1, 2006
Author(s)
Sudarsan Rachuri, Y H. Han, Sebti Foufou, Shaw C. Feng, Utpal Roy, Fujun Wang, Ram D. Sriram, Kevin W. Lyons
The important issue of mechanical assemblies has been a subject of intense research over the past several years. Most electromechanical products are assemblies of several components, for various technical as well as economic reasons. This paper provides an

Nano- and Atomic-Scale Length Metrology

January 1, 2006
Author(s)
Theodore V. Vorburger, Ronald G. Dixson, Joseph Fu, Ndubuisi George Orji, Shaw C. Feng, Michael W. Cresswell, Richard A. Allen, William F. Guthrie, Wei Chu
We discuss nano-scale length metrology of linewidth, step height, and line edge roughness (LER). These properties are of growing importance to the function and specification of semiconductor devices as the dimensions of semiconductor devices shrink to the

Collaborative Software Agents in Steel Industry

Intelligent Agents-Enabled Integrated Manufacturing Planning and Control

August 1, 2003
Author(s)
Shaw C. Feng, Keith A. Stouffer, Kevin K. Jurrens
agents provide a means to integrate various manufacturing software applications. The agents are typically executed in a computer-based collaborative environment, sometimes referred to as a multi-agent platform. The National Institute of Standards and

An Open Framework for the Assembly of Micro- and Nano-Scale Artifacts

June 1, 2003
Author(s)
Shaw C. Feng, Yung-Tsun Lee, Kevin W. Lyons
The design and manufacture of miniature devices have been increasing in both research laboratories and industry. The sizes of the devices continue to decrease to the nanometer scale. At the same time, the complexity of those devices has increased. To

A Web-Based Process/Material Advisory System

November 1, 2000
Author(s)
Y Chen, Satyandra K. Gupta, Shaw C. Feng
This paper describes a web-based process/material advisory system that can be used during conceptual design. Given a set of design requirements for a part during conceptual design stage, our system produces process sequences that can meet the design

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

Cost and Process Information Modeling for Dry Machining

July 1, 2000
Author(s)
Shaw C. Feng, M Hattori
The cost of using coolant in machining industry world-wide is very high. Through a literature survey, it costs multi-billion dollars for coolant acquisition and disposition in industrialized countries. Furthermore, chemical substances contained in colant

Manufacturing Planning and Execution Objects Foundation Interfaces

July 1, 2000
Author(s)
Shaw C. Feng
Process planning and manufacturing execution software systems provide two major functions in a product development cycle. Industries require the systems that support these two functions to be able to interoperate with other related manufacturing software

Incoporating Process Planning into Conceptual Design

September 1, 1999
Author(s)
Shaw C. Feng, Gordon A. Shaw, Walter W. Nederbragt, Serge Kaing, Ram D. Sriram
This paper describes recent developments in the Design and Process Planning Integration (DPPI) project at the National Institute of Standards and Technology (NIST). The project addresses the need for improved communication between design and process

NIST Response to MES Request for Information

September 1, 1999
Author(s)
Edward J. Barkmeyer Jr., Peter O. Denno, Shaw C. Feng, Evan K. Wallace, Albert T. Jones
This is a response from the National Institute of Standards (NIST) to OMG's Request for Information concerning the Manufacturing Execution System (MES) area [RFI3]. There has been quite a bit of previous work at NIST, related to this RFI which influenced

Conceptual Process Planning - A Definition and Functional Decomposition

August 1, 1999
Author(s)
Shaw C. Feng, Gordon A. Shaw, Yuyun Zhang
Conceptual process planning is an activity for designers to evaluate manufacturability and the manufacturing cost in the early design stage for mechanical parts production. Since major manufacturing costs of a product are committed in product specification
