Interoperability Testing for Shop Floor Measurement

December 28, 2007
Author(s)
Frederick M. Proctor, William G. Rippey, John A. Horst, Joseph Falco, Thomas Kramer
Manufactured parts are typically inspected to ensure quality. Inspection involves equipment and software from many different vendors, and interoperability is a major problem faced by manufacturers. The I++ Dimensional Measuring Equipment (DME)

A Mobile Robot Control Framework: From Simulation to Reality

December 7, 2007
Author(s)
Stephen B. Balakirsky, Frederick M. Proctor, Christopher J. Scrapper Jr, Thomas R. Kramer
In order to expedite the research and development of robotic systems and foster development of novel robot configurations, it is essential to develop tools and standards that allow researchers to rapidly develop, communicate, and compare experimental

Validating Portability of Step-NC Tool Center Programming

June 26, 2006
Author(s)
Sid Venkatesh, David Odendahl, Xun W. Xu, John L. Michaloski, Frederick M. Proctor, Thomas Kramer
A joint effort between Boeing and the National Institute of Standards and Technology (NIST) was undertaken for validating and evaluating STEP AP238 (STEP-NC) Conformance Class 1 (CC1) for 5-axis machining. STEP-NC is a new manufacturing standard to support

Comparing Algorithms: Rules of Thumb and an Example

August 24, 2004
Author(s)
Stephen B. Balakirsky, Thomas R. Kramer
This paper provides twenty rules of thumb for comparing algorithms having the same function, one of which is to be selected for use in an intelligent system. The rules are illuminated by a specific example, the comparison of three algorithms for dealing

STEP - Compliant NC Research: The Search for Intelligent CAD/CAPP/CAM/CNC Integration

May 31, 2004
Author(s)
Xun W. Xu, H Wang, Jian Mao, S T. Newman, Thomas Kramer, Frederick M. Proctor, John L. Michaloski
Since the first generation of NC machine tool was developed in 1950s, there have been many developments, which make today's NC machines completely unrecognisable from their early ancestors. These developments however are now being significantly limited by

Feature-Based Inspection and Control System

March 8, 2004
Author(s)
Thomas Kramer, John A. Horst, Hui-Min Huang, Elena R. Messina, Frederick M. Proctor, Harry A. Scott
This report describes an architecture and software system for automatically performing process planning and control code generation for cutting and inspecting prismatic piece parts. This "Feature-Based Inspection and Control System" (FBICS) consists of

NOT (Faster Implementation ==> Better Algorithm), A Case Study

October 1, 2003
Author(s)
Stephen B. Balakirsky, Thomas R. Kramer
Given two algorithms that perform the same task, one may ask which is better. One simple answer is that the algorithm that delivers the best answer is the better algorithm. But what if both algorithms deliver results of similar quality? In this case, a

User's Manual for Version 1.0 of the NIST DME Interface Test Suite for Facilitating Implementations of Version 1.1 of the I++ DME Interface Specification

August 21, 2003
Author(s)
John A. Horst, Thomas R. Kramer, Joseph A. Falco, Keith A. Stouffer, Hui-Min Huang, Frederick M. Proctor, Albert J. Wavering, Chengying Liu
This user's manual describes version 1.0 of the NIST Dimensional Measuring Equipment (DME) interface test suite intended to support implementations of version 1.1 of the I++ DME specification.

NOT (Faster Implementation ==> Better Algorithm), A Case Study

August 18, 2003
Author(s)
Stephen B. Balakirsky, Thomas R. Kramer
Given two algorithms that perform the same task, one may ask which is better. One simple answer is that the algorithm that delivers the ?best? answer is the better algorithm. But what if both algorithms deliver results of similar quality? In this case, a

Distributed Testing of an Equipment-Level Interface Specification

December 31, 2002
Author(s)
Joseph Falco, John A. Horst, Hui-Min Huang, Thomas Kramer, Frederick M. Proctor, Keith A. Stouffer, Albert J. Wavering
A test suite for an key interface within a dimensional measuring system (coordinate measuring machine or CMM) is presented. The test suite consists of test procedures, test definitions, and various testing utilities. A real-time, distributed test utilizing

4D/RCS Version 2.0: A Reference Model Architecture for Unmanned Vehicle Systems

August 22, 2002
Author(s)
James S. Albus, Hui-Min Huang, Elena R. Messina, Karl Murphy, Maris Juberts, Alberto Lacaze, Stephen B. Balakirsky, Michael O. Shneier, Tsai H. Hong, Harry A. Scott, Frederick M. Proctor, William P. Shackleford, John L. Michaloski, Albert J. Wavering, Thomas Kramer, Nicholas Dagalakis, William G. Rippey, Keith A. Stouffer, Steven Legowik
The 4D/RCS architecture provides a reference model for military unmanned vehicles on how their software components should be identified, organized, and interacting such that missions, especially those involving unknown or hostile environments, can be
