Dynamic Metrology and ASTM E57.02 Dynamic Measurement Standard

July 28, 2016
Author(s)
Roger V. Bostelman, Tsai H. Hong, Mili Shah, Steven Legowik
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

Machine Condition Detection For Milling Operations Using Low Cost Ambient Sensors

July 27, 2016
Author(s)
Anantha Narayanan Narayanan, Alec Kanyuck, Satyandra K. Gupta, Sudarsan Rachuri
In recent years, sensor technology and data mining capabilities have advanced greatly, allowing advanced manufacturing enterprises to closely monitor their manufacturing operations. Conditions such as tool breakage and tool wear can be predicted by

Multi-Fingered Robotic Grasping: A Primer

July 22, 2016
Author(s)
Stefano Carpin, Shuo Liu, Joseph Falco, Karl Van Wyk
Grasping and manipulation has generated significant interest in the robotics community, and robotic grasping emerged as an autonomous area of research since the development of the first robotic hands. Notwithstanding, robotic grasping continues to be one

Additive Manufacturing: A Trans-disciplinary Experience

July 20, 2016
Author(s)
Paul W. Witherell, Albert W. Jones, Yan Lu
Traditional manufacturing has long permitted disciplines to operate in isolation: with designers, material suppliers, and manufactures often able to function independently towards the singular goal of creating a product. As products have become

Synchrotron 4-dimensional imaging of two-phase flow through porous media

July 13, 2016
Author(s)
Felix H. Kim, D. Penumadu, P. Patel, X. Xiao, E. J. Garboczi, Shawn P. Moylan, M A. Donmez
Near real-time visualization of complex two-phase flow in a porous medium was demonstrated with dynamic 4D (3D + time) imaging at the 2-BM beam line of the Advanced Photon Source (APS) at Argonne National Laboratory. Advancing fluid fronts through tortuous

Mobile Manipulator Performance Measurement Towards Manufacturing Assembly Tasks

July 12, 2016
Author(s)
Roger V. Bostelman, Sebti Foufou, Steven A. Legowik, Tsai H. Hong
Mobile manipulator performance measurement research is relatively minimal as compared to that of robot arms. Measurement methods, such as optical tracking systems, are useful for measuring the performances of mobile manipulators, although at a much higher

Model-based engineering for the integration of manufacturing systems with advanced analytics

July 10, 2016
Author(s)
David Lechevalier, Anantha Narayanan Narayanan, Sudarsan Rachuri, Sebti Foufou, Yung-Tsun Lee
To employ data analytics effectively and efficiently on manufacturing systems, engineers and data scientists need to collaborate closely to bring their domain knowledge together. In this paper, we introduce a domain-specific modeling approach to integrate

Implementing the ISO 15746 Standard for Chemical Process Optimization

July 3, 2016
Author(s)
Guodong Shao, Peter O. Denno, Albert T. Jones, Yan Lu
Integrating advanced process control solutions with optimization (APC-O) solutions, within any factory, enables more efficient production processes. Currently, vendors who provide the software applications that implement control solutions are isolated and

Technical Data Packages (TDPs) from the Smart Manufacturing Systems (SMS) Test Bed

July 1, 2016
Author(s)
Thomas D. Hedberg, Moneer M. Helu, Allison Barnard Feeney
Data is collected from the Manufacturing Lab using the MTConnect standard. That data is aggregated and published internally and externally of NIST via web services. Three channels of data dissemination are available or becoming available from the SMS Test

Identifying uncertainty in Laser Powder Bed Fusion models

June 30, 2016
Author(s)
Felipe F. Lopez, Paul Witherell, Brandon Lane
A limitation frequently encountered in additive manufacturing (AM) models is a lack of indication about their precision and accuracy. Often overlooked, information on model uncertainty is required for validation of AM models, qualification of AM-produced

Survey of Research for Performance Measurement of Mobile Manipulators

June 30, 2016
Author(s)
Roger V. Bostelman, Tsai H. Hong, Jeremy A. Marvel
This survey provides the basis for developing research in the area of mobile manipulator performance measurement, an area that has relatively few research articles, as com-pared to other mobile manipulator research areas. The survey begins with a

Reusing Metamodels and Notation with Diagram Definition

June 28, 2016
Author(s)
Conrad E. Bock, Maged Elaasar
It is increasingly common for language specifications to separate visual forms (concrete syntax) from underlying concepts (abstract syntax), enabling languages to define multiple visual forms for the same underlying concepts, and for the same visual form

Framework for Standardization of Simulation Integrated Production Planning

June 15, 2016
Author(s)
Deogratias Kibira, Guodong Shao, Bjoern J. Johansson
Production planning is a complex problem that is typically decomposed into decisions carried out at different control levels. Production planning methods employed often assume a static environment; therefore, the plans developed may not be feasible if shop
