Author(s)
Shaw C. Feng, Prabir Sarkar, Che B. Joung, John Carrell
Sustainable manufacturing promotes manufacturing processes that minimize environmental and social impacts while maintaining economic benefits. To achieve this, manufacturers seek metrics and measurement methods to enable them to track the progress and

Agile Test Framework for Business-to-Business Interoperability

April 12, 2011
Author(s)
Jungyub Woo, Nenad Ivezic, H Cho
Business-to-business (B2B) applications are tested routinely for conformance and interoperability against a set of data exchange standards before deployment. However, the existence of many data exchange standards, planned utilizations, deployment

Lithography, Metrology and Nanomanufacturing

April 12, 2011
Author(s)
James A. Liddle, Gregg M. Gallatin
Semiconductor chip manufacturing is by far the predominant nanomanufacturing technology in the world today. Top-down lithography techniques are used for fabrication of logic and memory chips since, in order to function, these chips must essentially be

An Engineer Grapples with Sustainable Manufacturing

April 1, 2011
Author(s)
Vijay Srinivasan
A personal view by the author of how, as a research engineer and manager, first in the private sector and now in government service, he witnessed the emergence of a compelling case for sustainable manufacturing and also gained several important insights

Dimensional Metrology of Bipolar Fuel Cell Plates Using Laser Spot Triangulation Probes

March 22, 2011
Author(s)
Balasubramanian Muralikrishnan, Wei Ren, Dennis S. Everett, Eric S. Stanfield, Theodore D. Doiron
As in any engineering component, manufacturing a bipolar fuel cell plate for a polymer electrolyte membrane (PEM) hydrogen fuel cell power stack to within its stated design tolerances is critical in achieving the intended function. In a bipolar fuel cell

Measurement Traceability and Quality Assurance in a Nanomanufacturing Environment

March 8, 2011
Author(s)
Ndubuisi G. Orji, Ronald G. Dixson, Aaron Cordes, Benjamin Bunday, John Allgair
A key requirement for nano-manufacturing is maintaining acceptable traceability of measurements performed to determine size. Given that properties and functionality at the nanoscale are governed by absolute size, maintaining the traceability of dimensional

Merging Machining and Measurement for Cognitive Manufacturing

March 8, 2011
Author(s)
Fiona Zhao, Frederick M. Proctor, John A. Horst, Xun W. Xu
Machining process planning and measurement process planning have long received research attention from industry and academia. Machining and measurement process automation is well established for mass production in today's manufacturing systems. However

A Component-based Approach for Manufacturing Simulation

March 2, 2011
Author(s)
Frank H. Riddick, Yung-Tsun T. Lee, Deogratias Kibira, Stephen B. Balakirsky
Manufacturing systems can be very complex and are often costly to develop and operate. Simulation technology has been shown to be an effective tool for optimizing manufacturing system design, operations, and maintenance procedures. However, each

Advanced Sensing Towards Improved Forklift Safety

February 4, 2011
Author(s)
Roger V. Bostelman, William P. Shackleford
The National Institute of Standards and Technology's Intelligent Systems Division has been researching advanced three-dimensional (3D) imaging sensors and their use in manufacturing towards improving forklift safety. Experiments are presented in this paper

Mixed Pallet Stacking: An Overview and Summary of the 2010 PerMIS Special Session

February 4, 2011
Author(s)
Stephen B. Balakirsky, Henrik I. Christensen, Thomas R. Kramer, Pushkar Kolhe, Frederick M. Proctor
Stacking boxes of various sizes and contents on pallets (i.e. making mixed pallets) is a primary method of preparing goods for shipment from a warehouse to a store or other distant site. A special session of the 2010 PERMIS workshop was held to examine

Toward Energy Efficient Manufacturing Enterprises

February 2, 2011
Author(s)
Kevin W. Lyons, Alexander Weissman, Ram D. Sriram, Lalit Chordia
Industrial enterprises have significant negative impacts on the global environment. Collectively, from energy consumption to greenhouse gases to solid waste, they are the single largest contributor to a growing number of planet-threatening environmental

Metrics for Mixed Pallet Stacking

January 31, 2011
Author(s)
Stephen B. Balakirsky, Thomas R. Kramer, Frederick M. Proctor
Stacking boxes of various sizes and contents on pallets (i.e. making mixed pallets) is a primary method of preparing goods for shipment from a warehouse to a store or other distant site. Many billions of dollars are spent each year in preparing, shipping

Present Estimates of the Differences Between Thermodynamic Temperatures and the ITS-90

January 29, 2011
Author(s)
Joachim Fischer, M. DePodesta, K. D. Hill, Michael R. Moldover, Laurent Pitre, R. Rusby, Peter Steur, Osamu Tamura, R. White, L. Wolber
In 2005, the Consultative Committee for Thermometry (CCT) recommended the creation of a Mise en pratique for the definition of the kelvin and envisioned that future versions of the Mise en pratique would recommend values of the differences between

A Prototype of Modeling and Simulation for Sustainable Machining

January 19, 2011
Author(s)
Guodong Shao, Eric Chernow, Deogratias Kibira, Kevin W. Lyons
Modeling and simulation techniques have frequently been utilized to analyze manufacturing processes. The simulation of Numerically Controlled (NC) machine tools is preferred to real machine testing of the programs due to the potential savings of time and
