Automated Uncertainty Quantification Through Information Fusion in Manufacturing Processes

May 12, 2017
Author(s)
Saideep Nannapaneni, David Lechevalier, Anantha Narayanan Narayanan, Sankaran Mahadevan, Sudarsan Rachuri
Evaluation of key performance indicators (KPIs) such as energy consumption is essential for decision-making during the design and operation of smart manufacturing systems. The measurements of KPIs are strongly affected by several uncertainty sources such

Industrial Wireless Systems Workshop Proceedings

Optical tracking systems are used in a wide range of fields. The market for optical tracking systems has dramatically increased over the past several years to $1.2B revenue in 2014. This paper describes the new ASTM E3064 Standard test method procedures

Improvements in Accelerometer Calibration at NIST Using Digital Vibrometry

April 29, 2017
Author(s)
Beverly F. Payne, Richard A. Allen, Colleen E. Hood
Improvements in shaker design and laser vibrometer development has provided more precise calibration of accelerometers. Calibrations are performed at frequencies from 1Hz to 20 kHz with improved uncertainty and improved efficiency. The vibrometer mounting

Mobile Manipulator Stability Measurements

April 18, 2017
Author(s)
Roger V. Bostelman, Tsai H. Hong
Mobile manipulators are being marketed for material handling and other tasks. Manufacturers suggest the stability of the vehicle best when the onboard loading tapers the centroid to the center of the wheelbase as the payload height increases. Experiments

Economics of Additive Manufacturing

April 15, 2017
Author(s)
Douglas Thomas
There are three aspects to the economics of additive manufacturing. The first involves measuring the size of additive manufacturing. This includes measuring the value of the goods produced using this technology in the context of the total economy. The

Summary of the Symposium on Data Analytics for Advanced Manufacturing

April 13, 2017
Author(s)
Anantha Narayanan Narayanan, Ronay Ak, Yung-Tsun Lee, Rumi Ghosh, Sudarsan Rachuri
The Symposium on Data Analytics for Advanced Manufacturing was held in conjunction with the 2016 IEEE International Conference on Big Data in Washington D.C. on December 6-7, 2016. The Symposium's goal was to address manufacturing industries' issues, needs

Design for Powder Bed Fusion of Metal Parts

April 1, 2017
Author(s)
Paul Witherell
Advancements in metals-focused technologies have taken 3D printing from a prototyping technology to an advanced, additive manufacturing (AM) production technology having a roadmap for even greater advancements [1].Most of today's commercially available

STEP File Analyzer Software

March 30, 2017
Author(s)
Robert R. Lipman
The STEP File Analyzer is a software tool that generates a spreadsheet or CSV files from a STEP (ISO 10303 –STandard for Exchange of Product model data) Part 21 file. STEP files are used to represent product and manufacturing information (PMI) and for data

A Suite of Ontologies for Robotics and Automation

Author(s)
Sandro R. Fiorini, Julita Bermejo-Alonso, Paulo Goncalves, Edison Pignaton de Freitas, Alberto Olivares Alarcos, Joanna Isabelle Olszewska, Edson Prestes, Craig I. Schlenoff, Veera S. Ragavan, Signe Redfield, Bruce Spencer, Howard Li
One of the basic requirements for any type of robot communication (whether with other robots or humans) is the need for a common vocabulary along with clear and concise definitions. With the growing complexity of tasks that robots are expected to perform

What More Agile Robots Could Mean for Consumers

March 24, 2017
Author(s)
Craig I. Schlenoff
The ways that developers of robots have talked about their craft have been highly specialized to a given domain-and sometimes have varied even within the domain. This has made it difficult to share advances across the landscape of robot R&D and, in turn

Neuroelectronic Device Process Development and Challenge

March 16, 2017
Author(s)
Jessie Zhang, Gymama Slaughter, Matthew Robinson, Joel Tyson
One of the major challenges of brain activity monitoring is to obtain high quality signals from the brain using metal electrodes. The probes consisting of metal electrodes have to be thin enough without damaging the tissue while maintaining good contact to

Towards a Digital Thread and Data Package for Metals Additive Manufacturing

March 6, 2017
Author(s)
Paul Witherell, Yan Lu, Shaw C. Feng, Duckbong Kim
Additive manufacturing (AM) has been envisioned by many as the next industrial revolution. Potential benefits of AM include the production of low-volume, customized, complicated parts/products, supply chain efficiencies, shortened time-to-market, and

Guideline for Automatic Guided Vehicle Calibration

March 2, 2017
Author(s)
Steven Legowik, Roger V. Bostelman, Tsai H. Hong, Elena R. Messina
This report documents the steps followed to calibrate an all-wheel steer Automatic Guided Vehicle (AGV) for optimal performance. Proper calibration of the steering and drive parameters of an AGV are critical for accurate dead-reckoning navigation, and
