Activity Model for Homogenization of Data Sets in Laser-based Powder Bed Fusion

January 14, 2017
Author(s)
Shaw C. Feng, Paul W. Witherell, Duck B. Kim
Additive Manufacturing (AM) processes are the integration of many different science and engineering-related disciplines, such as material metrology, design, process planning, in-situ and off-line measurements, and controls. Major integration challenges

An Open Web-Based Repository for Capturing Manufacturing Process Information

December 1, 2016
Author(s)
William Z. Bernstein, Mahesh Mani, Katherine C. Morris, Kevin W. Lyons, Bjoern J. Johansson
With recent progress in developing more effective models for representing manufacturing processes, this paper presents an approach towards an open web-based repository for storing manufacturing process information. The repository is envisioned to include

Sensor Calibration and Registration for Mobile Manipulators

November 16, 2016
Author(s)
Steven Legowik, Roger V. Bostelman, Tsai H. Hong
This paper describes the methods used to register a mobile manipulator to a workstation to perform assembly tasks. The nonlinear, least square model of the system is formulated and Ceres Solver[1] is used to compute the position of the robot arm relative

Towards a Road-Mapping Ontology for Open Innovation in Smart Manufacturing

October 30, 2016
Author(s)
Nenad Ivezic, Miroslav Ljubicic
In nascent areas, such as Smart Manufacturing, new collaborative research and development programs (R&D) are frequently formed with the goal to ignite the innovation lifecycle. Yet, clearly formulating common goals and enabling shared understanding of key

Cyber-physical Systems Engineering for Manufacturing

October 7, 2016
Author(s)
Allison Barnard Feeney, Simon P. Frechette, Vijay Srinivasan
There is a convergence of interests in cyber-physical systems, systems engineering, and manufacturing innovation in the United States. The U.S. National Institute of Standards and Technology (NIST) has undertaken research programs in smart manufacturing

An Activity Model for Factory Design and Improvement

October 4, 2016
Author(s)
Kiwook Jung, Sangsu Choi, Boonserm Kulvatunyou, Hyunbo Cho, Katherine C. Morris
Smart Manufacturing Systems (SMS) are envisioned to contain highly-automated and IT-driven production systems. To address the complexity that arises in such systems, a standard and holistic model for describing the activities and their inter-relationships

Reference Architecture for Smart Manufacturing Part 1: Functional Models

September 29, 2016
Author(s)
Edward J. Barkmeyer Jr., Evan K. Wallace
This document is a part of the definition of a reference architecture for the integration of manufacturing software applications in the areas of fabrication and assembly of discrete electro- mechanical parts. This document captures, at a high level of

An analysis of technologies and standards for designing smart manufacturing systems

September 20, 2016
Author(s)
Boonserm Kulvatunyou, Katherine C. Morris, Sangsu Choi, Kiwook Jung
Smart manufacturing is defined by high degrees of automation. Automation, in turn, is defined by clearly defined processes. The use of standards in this environment is not just common place but essential to creating repeatable and reliable systems. As with

Editorial: Special Issue on Industrial Robot Agility

September 14, 2016
Author(s)
Craig I. Schlenoff, Stephen B. Balakirsky, Murad Kurwa
The robotic systems of tomorrow need to be capable, flexible, and agile. These systems need to perform their duties at least as well as human counterparts, be quickly re-tasked to other operations, and cope with a wide variety of unexpected environmental

Networked Engineering Notebooks for Smart Manufacturing

September 8, 2016
Author(s)
Peter O. Denno
A goal of the industrial internet is to make information about manufacturing processes and resources available wherever decision making may be required. Agile use of information is a cornerstone of data analytics, but analytical methods more generally

The Paradigm Shift in Smart Manufacturing System Ar-chitecture

September 4, 2016
Author(s)
Yan Lu, Frank H. Riddick, Nenad Ivezic
In response to demanding market conditions, Smart Manufacturing (SM) seeks to integrate advanced manufacturing methods, operational technologies (OT), and information and communication technologies (ICT) to drive the creation of manufacturing systems with

Virtual Factory Framework for Supporting Production Planning and Control

September 2, 2016
Author(s)
Deogratias Kibira, Guodong Shao
Developing optimal production plans for smart manufacturing systems is challenging if events change dynamically. A virtual factory incorporating engineering tools, simulation, and optimization generates and communicates performance data to guide wise

Promoting Model-Based Definition to Establish a Complete Product Definition

August 31, 2016
Author(s)
Shawn P. Ruemler, Kyle E. Zimmerman, Nathan W. Hartman, Thomas D. Hedberg Jr., Allison Barnard Feeney
Most of the manufacturing and engineering industries, especially aerospace and defense, are evolving and starting to use 3D models as the central knowledge artifact for product data and product definition, or what is known as Model-based Definition (MBD)

DIGITAL SOLUTIONS FOR INTEGRATED AND COLLABORATIVE ADDITIVE MANUFACTURING

August 23, 2016
Author(s)
Yan Lu, Paul Witherell, Felipe F. Lopez, Ibrahim Assouroko
Software tools, knowledge of materials and process models, and data provide three pillars on which Additive Manufacturing (AM) lifecycles and value chains can be supported. These pillars leverage efforts dedicated to the development of AM databases, high

A Summary Report on the Model-Based Enterprise Capability Index and Guidebook Workshop

August 22, 2016
Author(s)
Joan Pellegrino, Yannick Tamm, Allison Barnard Feeney, Thomas D. Hedberg Jr.
The National Institute of Standards and Technology (NIST) held a "Model-Based Enterprise Summit" from April 12-14, 2016 with the intention of identifying challenges, research, implementation issues, and lessons learned in manufacturing and quality
