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

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

An Examination of National Supply-Chain Flow Time

December 4, 2017
Author(s)
Douglas Thomas, Anand M. Kandaswamy
The US and other national governments invest in research and development to spur competitiveness in their domestic manufacturing industries. However, there are limited studies on identifying the research efforts that will have the largest possible return

Author(s)
Zeid Kootbally, Thomas Kramer, Craig I. Schlenoff, Satyandra K. Gupta
The Agility Performance of Robotic Systems (APRS) project at the National Institute of Standards and Technology (NIST) is using Web Ontology Language (OWL) ontologies for modeling in a robotic kitting workstation. The new technical idea for the APRS

Effect of the Additive Manufacturing Process on Cutting Forces in Hybrid Manufacturing

November 3, 2017
Author(s)
Michael Gomez, Andrew Honeycutt, Jarred C. Heigel, Tony Schmitz
Powder bed fusion (PBF) enables metal components with complex geometries to be made via additive manufacturing (AM). Disadvantages of AM are rougher surface finish and lower achievable dimensional tolerances compared to computer numerically-controlled (CNC

Model of Mobile Manipulator Performance Measurement using SysML

November 3, 2017
Author(s)
Roger V. Bostelman, Sebti Foufou, Tsai H. Hong, Mili Shah
Test methods for measuring safety and performance of mobile manipulators have yet to be developed. Therefore, potential mobile manipulator users cannot compare one system to another. Systems Modeling Language (SysML) is a general-purpose modeling language
