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

Using Shared Memory in Real-Time Linux

January 1, 1999
Author(s)
Frederick M. Proctor
Shared memory can be used in place of first-in-first-out queues (FIFOs) for communication between Linux operating system user processes and real-time Kernel modules. Shared memory has some features (e.g., fast access to large data structures, multiple

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

JAVA-Based Tools for Development and Diagnosis of Real-Time Control Systems

September 1, 1998
Author(s)
William P. Shackleford, Frederick M. Proctor
The National Institute of Standards and Technology (NIST) has been using the Real-time Control System (RCS) Reference Model Architecture for building control systems based on a hierarchy of cyclically executing control modules. This paper describes the
