Distributed Testing of a Device-Level Interface Specification for a Metrology System

January 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

An Intelligent Systems Architecture for Manufacturing (ISAM); A Reference Model Architecture for Intelligent Manufacturing Systems

January 1, 2002
Author(s)
James S. Albus, John A. Horst, Hui-Min Huang, Thomas Kramer, Elena R. Messina, Alex Meystel, John L. Michaloski, Frederick M. Proctor, Harry A. Scott, Edward J. Barkmeyer Jr., M. K. Senehi
The Intelligent Systems Architecture for Manufacturing (ISAM) addresses the application of intelligent systems to the manufacturing enterprise at three degrees of abstraction: 1) a conceptual framework for developing metrics, standards, and performance

A Feature-Based Inspection and Machining System

August 1, 2001
Author(s)
Thomas R. Kramer, Hui-Min Huang, Elena R. Messina, Frederick M. Proctor, Harry A. Scott
This paper describes an architecture for a system for machining and inspectingmechanical piece parts and an implementation of it called the Feature-BasedInspection and Control System (FBICS). In FBICS, the controller of a machiningcenter or coordinate

Analysis of Dimensional Metrology Standards

June 1, 2001
Author(s)
Thomas R. Kramer, John Evans, Simon P. Frechette, John A. Horst, Hui-Min Huang, Elena R. Messina, Frederick M. Proctor, William G. Rippey, Harry A. Scott, Theodore V. Vorburger, Albert J. Wavering
This is an analysis of standards related to dimensional metrology, with recommendations regarding standards development. The analysis focuses on the degree to which existing and developing standards provide a complete set of non-overlapping specifications

The NIST RS274NGC Interpreter - Version 3

August 1, 2000
Author(s)
Thomas R. Kramer, Frederick M. Proctor, Elena R. Messina
This report describes an interpreter which reads numerical control code and produces calls to a set of canonical machining functions. The interpreteris a software system written in the C++ programming language. The output of the interpreter may be used to

An Architecture and Tool for Large-scale System Control with a manufacturing system application

June 1, 2000
Author(s)
Hui-Min Huang, James S. Albus, William P. Shackleford, Harry A. Scott, Thomas R. Kramer, Elena R. Messina, Frederick M. Proctor
This paper describes a reference architecture that is applicable to multiple classes of large-scale, complex real-time control systems. An associated tool, Generic Shell, is also described. Generic Shell employs a set of code templates that facilitate

An Automated Hierarchical Process Planning System

April 28, 2000
Author(s)
Thomas R. Kramer, Hui-Min Huang, Elena R. Messina, Frederick M. Proctor, Harry A. Scott
This paper describes an automated hierarchical process planning system for machining and inspecting discrete parts in an RCS type control system. The system integrates planning with control of a 3-axis machining center and a coordinate measuring machine

A Knowledge-Based Inspection Workstation

November 3, 1999
Author(s)
Elena R. Messina, John A. Horst, Thomas R. Kramer, Hui-Min Huang, Tsung-Ming Tsai, E Amatucci
We are building an inspection workstation development environment to use as a testbed for understanding what types of knowledge, e.g., data, algorithms, and processes, can increase the productivity of inspection operations. Inspection can be more efficient

Component Specifications for Robotics Integration

May 1, 1999
Author(s)
Elena R. Messina, John A. Horst, Thomas R. Kramer, Hui-Min Huang, John L. Michaloski
Robotics researchers have been unable to capitalize easily on existing software components to speed up their development e orts and maximize their system's capabilities. A component-based approach for building the software for robotics systems can provide

A Feature-Based Machining System Using STEP

November 30, 1998
Author(s)
Frederick M. Proctor, Thomas Kramer
Discrete part manufacturing flows from a design phase in which product information is defined to a manufacturing phase in which the processes are planned and executed. Process planning typically culminates with the generation of numerical control (NC)

The NIST DMIS Interpreter: Version 2

October 1, 1998
Author(s)
Thomas Kramer, Frederick M. Proctor, William G. Rippey, Harry A. Scott
The National Institute of Standards and Technology (NIST) DMIS interpreter is a software system that reads control code programs in the DMIS language (described below in Section 1.2), produces calls to a set of canonical commands for coordinate measuring

The NIST DMIS Interpreter: Version 2

October 1, 1998
Author(s)
Thomas R. Kramer, Frederick M. Proctor, William G. Rippey, Harry A. Scott
This report describes an interpreter which reads a file of numerical control code for a coordinate measuring machine (CMM), produces calls to a set of canonical CMM functions, and writes inspection report files. The interpreter is a software system written

A framework for control architectures

July 1, 1998
Author(s)
M. K. Senehi, Thomas R. Kramer
The development of architectures for control systems has been an active area of research for at least twenty years. This research has produced many different architectures which use different terminologies and address different issues. In order to analyse
