Towards Annotations and Product Definitions for Additive Manufacturing

May 20, 2016
Author(s)
Paul W. Witherell, Gaurav Ameta, Jennifer Herron
As AM is viewed more and more as a production-capable technology, the costs of complexity have become increasingly apparent in the form of information requirements. With design flexibilities come the need to capture and communicate complex shapes. In

Automating Robot Planning using Product and Manufacturing Information

May 9, 2016
Author(s)
Frederick M. Proctor, Gijs van der Hoorn, Robert R. Lipman
Advances in sensing, modeling, and control have made it possible to increase the accuracy of robots, and enable them to perform in dynamic environments. Often, performance deficiencies are not evident until late in the development of the manufacturing

Addressing Perception Uncertainty Induced Failure Modes in Robotic Bin-Picking

May 3, 2016
Author(s)
Krishnanand N. Kaipa, Akshaya S. Kankanhalli-Nag, Nithyananda B. Kumbla, Shaurya Shriyam, Srudeep Somnaath Thevendria-Karthic, Jeremy Marvel, Satyandra K. Gupta
We present a comprehensive approach to handle perception uncertainty to reduce failure rates in robotic bin-picking. Our focus is on mixed-bins. We identify the main failure modes at various stages of the bin-picking task and present methods to recover

In-Situ Metrology to Characterize Water Vapor Delivery during Atomic Layer Deposition

May 2, 2016
Author(s)
Tariq Ahmido, William A. Kimes, Brent A. Sperling, Joseph T. Hodges, James E. Maslar
Water is often employed as the oxygen source in metal oxide atomic layer deposition (ALD) processes. It has been reported that variations in the amount of water delivered during metal oxide ALD can impact the oxide film properties. Hence, one contribution

Analysis and Optimization based on Reusable Knowledge Base of Process Performance Models

April 29, 2016
Author(s)
Alexander Brodsky, Guodong Shao, Mohan Krishnamoorthy, Anantha Narayanan Narayanan, Daniel Menasce?, Ronay Ak
In this paper, we propose an architectural design and software framework for fast development of descriptive, diagnostic, predictive, and prescriptive analytics solutions for dynamic production processes. The proposed architecture and framework will

Diagnostics for geometric performance of machine tool linear axes

April 29, 2016
Author(s)
Gregory W. Vogl, M A. Donmez, Andreas Archenti
Machine tools degrade during operations, yet knowledge of degradation is elusive; accurately detecting degradation of linear axes is mainly a manual and time-consuming process. Thus, manufacturers need automated and efficient methods to diagnose the

Baseline Tailor User Guide

April 25, 2016
Author(s)
Joshua Lubell
This guide describes how to use Baseline Tailor, a software tool for navigating the United States Government's Cybersecurity Framework and for tailoring the National Institute of Standards and Technology Special Publication 800-53 Revision 4 security

OAGi/NIST Workshop on Open Cloud Architecture for Smart Manufacturing

April 20, 2016
Author(s)
Nenad Ivezic, Boonserm Kulvatunyou, Yan Lu, Yunsu Lee, Jaehun Lee, Albert W. Jones, Simon P. Frechette
This report summarizes the results from the OAGi/NIST Workshop on Open Cloud Architecture for Smart Manufacturing, which was held at the National Institute of Standards and Technology on May 5, 2015. The workshop was a forum for manufacturers and providers

Test Methods for the Evaluation of Manufacturing Mobile Manipulator Safety

April 20, 2016
Author(s)
Jeremy A. Marvel, Roger V. Bostelman
A test methodology for evaluating the safety of mobile manipulators (robot arms mounted on mobile bases) is presented. This methodology addresses the safety concerns relevant to modern, agile manufacturing practices in which mobile manipulators are

Enabling Quantitative Optical Imaging for In-die-capable Critical Dimension Targets

April 4, 2016
Author(s)
Bryan M. Barnes, Mark Alexander Henn, Martin Y. Sohn, Hui Zhou, Richard M. Silver
Dimensional scaling trends will eventually bring the semiconductor critical dimensions (CDs) down to only a few atoms in width. New optical techniques are required to address intra-die variability for these CDs using sufficiently small in-die metrology

A domain-specific language for model composition and verification of multidisciplinary models

March 22, 2016
Author(s)
Peter O. Denno, Anantha Narayanan Narayanan, Amogh Kulkarni, Daniel Balasubramanian, Gabor Karsai
Complex, engineered products and manufacturing processes often necessitate integrated analysis that cuts across physical domains and engineering disciplines. When the domain-specific models that contribute to the overall analysis process are available then

Laser Welding of Dual-Phase Galvanized Sheet Steel

March 18, 2016
Author(s)
Stephanie L. Miller, Erik A. Pfeif, Andrei F. Kazakov, Esther Baumann, Marla L. Dowell
Laser welding has many advantages over traditional joining methods, but remains underutilized. NIST has undertaken an initiative to improve predictions of weldability, reliability, and performance of laser welds. This study investigates butt welding of

Testing the Digital Thread in Support of Model-Based Manufacturing and Inspection

March 8, 2016
Author(s)
Thomas D. Hedberg, Joshua Lubell, Lyle Fischer, Larry Maggiano, Allison Barnard Feeney
A number of manufacturing companies have reported anecdotal evidence describing the benefits of Model-Based Enterprise (MBE). Based on this evidence, the entire industry has embraced a vision to deploy MBE. In our view, the best chance of realizing this

The New Frontiers in Computational Modeling of Material Structures

February 23, 2016
