Quantifying the Performance of MT-Connect in a Distributed Manufacturing Environment

October 8, 2009
Author(s)
John L. Michaloski, Byeong Eon Lee, Frederick M. Proctor, Sid Venkatesh, Sidney Ly
In the CNC manufacturing world, the continuing pressure to reduce costs and improve time to market places a premium on smarter ways of manufacturing and intensifies the need to integrate feedback from the shop floor into the enterprise business systems

Standardization of Auxiliary Equipment for Next Generation CNC Machining

October 17, 2008
Author(s)
David Odendahl, Sid Venkatesh, John L. Michaloski, Frederick M. Proctor
This paper presents the recent work of the Open Modular Architecture Control (OMAC) Machine Tool Working Group to support STEP-NC, which is a new standard for the exchange of comprehensive Computer Numerical Control (CNC) manufacturing data. Because of the

Case Study in the Challenges of Integrating CNC Production and Enterprise Systems

December 3, 2007
Author(s)
Sid Venkatesh, B. Sides, John L. Michaloski, Frederick M. Proctor
Integration of factory floor Computer Numerical Control (CNC) information into Enterprise Resource Planning (ERP) subsystems has been difficult, if not impossible, as traditionally, factory floor machines have been islands of automation. Boeing/NIST/Okuma

Closed Loop CNC Manufacturing -- Connecting the CNC to the Enterprise

November 26, 2007
Author(s)
Sid Venkatesh, Rich Morihara, John L. Michaloski, Frederick M. Proctor
Closed Loop manufacturing describes the use of feedback from a Computer Numerical Control (CNC) to the Enterprise Resource Planning (ERP) to help in business operations. Although conceptually simple, many obstacles make CNC-ERP connectivity difficult -

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

Improving CNC Machining Accuracy Through Thermal Model-Based Control

July 21, 2004
Author(s)
John L. Michaloski, Frederick M. Proctor, Johannes A. Soons, R King, W Bakula, H Dominguez, N Frampton
The United States Army has a requirement to machine munitions to strict tolerances so that the munitions will launch properly and the explosives will detonate correctly. High precision parts require machine tools to operate with a high degree of accuracy

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

Expanding the Role of Finite State Machine Technology in Open Architecture Control

August 21, 2003
Author(s)
John L. Michaloski, Frederick M. Proctor, William G. Rippey, S Kolla
Modern machine control systems rely heavily on software to achieve system functionality. Until recently, control software?s primary purpose was to provide logic and sequencing of machine execution. With computer hardware now providing power and memory to

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

Evaluation of Component-Based Reconfigurable Machine Controllers

June 13, 2002
Author(s)
S Kolla, John L. Michaloski, William G. Rippey
The lack of interoperability and integration standards is severely hindering manufacturing productivity. To address this problem, a General Motion Control (GMC) Testbed has been developed at National Institute of Standards and Technology (NIST) with one of
