The National Institute of Standards and Technology (NIST) in collaboration with the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) has developed the Standard Reference Material (SRM) 2460 bullets and 2461 casings. NIST and ATF are proposing to

Rationales and Mechanisms for Revitalizing US Manufacturing R&D Strategies

January 29, 2010
Author(s)
Gregory C. Tassey
The race to economic superiority is increasingly occurring on a global scale. Competitors from different countries are employing new types of growth strategies in attempts to win that race. The United States cannot, therefore, continue to rely on outdated

The Semantics of Modules in Common Logic

January 20, 2010
Author(s)
Fabian M. Neuhaus
Common Logic (CL) is an ISO standard that specifies a family of knowledge representation languages. The function of modules within CL is to support local context with a local domains of discourse. Modules play a crucial role since they enable users to

DYNAMIC PERCEPTION WORKSHOP REPORT: Requirements and Standards for Advanced Manufacturing

January 14, 2010

The Dynamic Perception workshop was intended to further the development of standardized, reproducible, and portable test methods that can advance the technology of sensors and perception systems for new, flexible robotic and automation applications in

Feature-based Process Planning Based on STEP

December 31, 2009
Author(s)
Thomas R. Kramer, Frederick M. Proctor
This chapter begins by describing characteristics a process planning language should have. Then it discusses the extent to which four process planning languages have these characteristics. The first two of these are STEP standard process planning languages

Carbon Weight Analysis for Machining Operation and Allocation for Redesign

December 16, 2009
Author(s)
Gaurav Ameta, Mahesh Mani, Sudarsan Rachuri, Kevin W. Lyons, Shaw C. Feng, Ram D. Sriram
The objective of this research is to explore and develop a new methodology for computing carbon weight (CW) - often referred to as carbon footprint, in manufacturing processes from the part level to assembly level. In this initial study we focused on

QOD Standalone Users Guide

December 16, 2009
Author(s)
Julien C. Cuvillier, Katherine C. Morris
This report describes installation and use of the XML Schema Quality of Design Standalone testing system, or QOD Standalone. QOD Standalone is one of several tools produced by NIST's XML Testbed project within the Manufacturing Systems Integration Division

From Simulation to Real Robots with Predictable Results: Methods and Examples

December 1, 2009
Author(s)
Stephen B. Balakirsky, Stefano Carpin, George Dimitoglou, Benjamin Balaguer
From a theoretical perspective, one may easily argue (as we will in this chapter) that simulation accelerates the algorithm development cycle. However, in practice many in the robotics development community share the sentiment that "Simula-tion is doomed

STEPNC++ - An Effective Tool for Feature-based CAM/CNC

December 1, 2009
Author(s)
John L. Michaloski, Thomas R. Kramer, Frederick M. Proctor, Xun Xu, Sid Venkatesh, David Odendahl
This chapter discusses the realization of direct translation of feature-based CAM files into feature-based CNC part program files. The information infrastructure that allows this to happen is STEP-NC, as described by ISO 14649 Parts 10 and 11. Among the

Traceability for Ballistics Signature Measurements in Forensic Science

December 1, 2009
Author(s)
Jun-Feng Song, Theodore V. Vorburger, Susan M. Ballou, Li Ma, Thomas Brian Renegar, Xiaoyu Alan Zheng, Martin Ols
The National Institute of Standards and Technology (NIST) in collaboration with the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) has developed the Standard Reference Material (SRM) 2460 Bullets and 2461 Casings. NIST has also developed a 2D

Performance Measurements Towards Improved Manufacturing Vehicle Safety

November 23, 2009
Author(s)
Roger V. Bostelman, William P. Shackleford
In this paper, we describe the current 2D (dimensional) sensor and ideal sensor configurations if 3D imagers are mounted on manufacturing vehicles in an attempt to make them more safe. Towards the ideal sensor configuration, three experiments were

An Enabler for Supplier Discovery in Virtual Supply Chains: A Shared Terminology

November 5, 2009
Author(s)
Steven J. Fenves, Eswaran Subrahmanian, Mahesh Mani, Albert T. Jones
Rigid supply-chain organizational structures are giving way to highly dynamic collaborative partnerships. These partnerships will develop rapidly by composing global manufacturing resources in response to open market opportunities; and, they will disband

Interoperability and the DMIS experience

October 30, 2009
Author(s)
John A. Horst
Because they enable true interoperability, information exchange standards can help manufacturers reduce cost and improve product quality, but only if the standards are developed and implemented correctly. We will answer questions manufacturers and

Ontological Product Modeling for Collaborative Design

October 30, 2009
Author(s)
Conrad E. Bock, XuanFang Zha, Hyo W. Suh, Jae H. Lee
This paper presents a product modeling language for collaborative design that has the benefits of ontology and expanded capabilities in conventional product modeling. The proposed approach uses ontology to increase flexibility and accuracy in combining
