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

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
