Introduction: Special Issue on Enabling Robot Autonomy

March 14, 2018
Author(s)
Craig I. Schlenoff, Stephen B. Balakirsky, Henrik I. Christensen
Today's state-of-the-art robots are capable of sub-millimeter movement accuracy when performing highly repeatable tasks. They perform extremely well in highly structured environments, where objects are in well-known, predictable locations. However, robots

Contextualizing Manufacturing Data for Lifecycle Decision Making

March 12, 2018
Author(s)
William Z. Bernstein, Thomas D. Hedberg, Moneer M. Helu, Allison Barnard Feeney
Product Lifecycle Management (PLM) systems manage the flow of data about the product and the processes that are used throughout the product's lifecycle so that the right information is delivered at the right time to the right systems. Manufacturing in the

Standard Data-Based Predictive Modeling for Power Consumption in Turning Machining

February 26, 2018
Author(s)
Seungjun Shin, Jungyub Woo, Sudarsan Rachuri, Prita Meilanitasari
In the metal cutting industry, power consumption is an important metric in the analysis of energy efficiency since it relates to energy consumption of machine tools. Much of the research has developed predictive models that correlate process planning

Multi-Robot Assembly Strategies and Metrics

January 26, 2018
Author(s)
Jeremy A. Marvel, Roger V. Bostelman, Joseph A. Falco
We present a survey of multi-robot assembly applications and methods, and describe trends and general insights into the multi-robot assembly problem for industrial applications. We focus on fixtureless assembly strategies featuring two or more robotic

Strategies for Improving Robot Registration Performance

January 26, 2018
Author(s)
Karl Van Wyk, Jeremy A. Marvel
The ability to calculate rigid-body transformations between arbitrary coordinate systems (i.e., registration) is an invaluable tool in robotics. This effort builds upon previous work by investigating strategies for improving the registration accuracy

Hybrid Datafication of Maintenance Logs from AI-Assisted Human Tags

January 15, 2018
Author(s)
Thurston B. Sexton, Michael P. Brundage, Michael L. Hoffman, Katherine C. Morris
One of the main challenges of applying AI to some datasets derives from the datasets themselves being unstructured, unclear, and ambiguous. Furthermore, the insights that are to be gained reflect the quality of the data itself; if the data is skewed, so

Orientation Uncertainty Characteristics of Some Pose Measuring Systems

December 31, 2017
Author(s)
Marek Franaszek, Geraldine S. Cheok
We investigate the performance of pose measuring systems which determine an object's pose from measurement of a few fiducial markers attached to the object. Such systems use point-based, rigid body registration to get the orientation matrix. Uncertainty in

Extending and Evaluating the Model-based Product Definition

December 22, 2017
Author(s)
Nathan W. Hartman, Jesse Zahner, Thomas D. Hedberg Jr., Allison Barnard Feeney
Industrial practice is in a state of transition, away from the use of drawings towards the use of annotated 3D CAD models as a means of communication. Working as a representation of an object or a system, a model-based product definition (MBD) is used to

Research directions for an open unit manufacturing process repository: A collaborative vision

December 20, 2017
Author(s)
William Z. Bernstein, Arun Bala Subramaniyan, Alexander Brodsky, Ian C. Garretson, Karl Haapala, Donald E. Libes, Katherine C. Morris, Rong Pan, Vittaldas Prabhu, Arkopaul Sarkar, Arvind Shankar Raman, Zhenhua Wu
The design of manufacturing systems can see dramatic improvements through the use of digital technologies for modeling and simulation prior to deployment. At the 2017 ASME International Manufacturing Science and Engineering Conference held jointly with the

Design and Configuration of the Smart Manufacturing Systems Test Bed

December 18, 2017
Author(s)
Thomas D. Hedberg, Moneer M. Helu
The purpose of this document is to describe the design and configuration of the NIST Smart Manufacturing Systems Test Bed. Prospective developers, technical-assessment personnel, researchers, and interested end-users are the intended audience of this

Software Requirements Specification to Distribute Manufacturing Data

December 18, 2017
Author(s)
Thomas D. Hedberg, Moneer M. Helu, Marcus W. Newrock
The purpose of this document is to describe the requirements specifications for applications and a data repository to distribute manufacturing data. Prospective developers, technical-assessment personnel, and interested end-users are the intended audience

A Method for Key Performance Indicator Assessment in Manufacturing Organizations

December 12, 2017
Author(s)
Patrick Hester, Barry Ezell, Andrew Collins, John A. Horst, Kaleen Lawsure
Key Performance Indicators (KPIs) are an essential element of an organization's ability to monitor its strategic health, helping to ensure the strategic goals of the organization are achieved. However, KPI assessment and improvement is often an ad hoc and

Automatic Localization of Casting Defects with Convolutional Neural Networks

December 11, 2017
Author(s)
Ronay Ak, Max Ferguson, Yung-Tsun T. Lee, Kincho H. Law
Automatic localization of defects in metal castings is a challenging task, owing to the rare occurrence and variation in appearance of defects. Convolutional neural networks (CNN) have recently shown outstanding performance in both image classification and

Issues in Synthetic Data Generation for Advanced Manufacturing

December 11, 2017
Author(s)
Donald E. Libes, David Lechevalier, Sanjay Jain
Research into advanced manufacturing requires data for analysis. There is limited access to real-world data and a need for more data of varied types and larger quantity. This paper explores the issues, and identifies challenges, and suggests requirements
