A Survey on Knowledge Transfer for Manufacturing Data Analytics

November 5, 2018
Author(s)
Seung Hwan Bang, Ronay Ak, Anantha Narayanan Narayanan, Yung-Tsun T. Lee, Hyunbo Cho
Data analytics techniques have been used for numerous manufacturing applications in various areas. A common assumption of data analytics models is that the environment that generates data is stationary, that is, the feature (or label) space or distribution

A more efficient method for calibrating discrete element method parameters for simulations of metallic powder used in additive manufacturing

October 31, 2018
Author(s)
Stephen R. Geer, Michelle Bernhardt, Edward Garboczi, Justin Whiting, Alkan Donmez
Laser powder bed fusion (LPBF) is an additive manufacturing (AM) process that uses a high-power laser to selectively melt metal powder that has been spread, layer-by-layer, to create parts with highly complex features. Because of the strong influence that

Performance Metrics and Test Methods for Robotic Hands (Draft)

October 31, 2018
Author(s)
Joseph A. Falco, Karl Van Wyk, Elena R. Messina
Increasing the flexibility and general-purpose applicability of robots is a longstanding goal. Several avenues of research are addressing these goals, ranging from integration of multiple sensors to allow robots to perceive their surroundings and adapt

Standards-based integration of advanced process control and optimization

October 28, 2018
Author(s)
Guodong Shao, Hasan Latif, Carla Martin, Peter O. Denno
Integration of process control with optimization is critical to Smart Manufacturing (SM). Oftentimes, however, the process control solutions from one vendor do not interoperate with the optimization solutions of another. Incompatibilities among the

Effects of Consumer Use Practices on Nanosilver Release from Commercially Available Food Contact Materials

October 23, 2018
Author(s)
Susana Addo Ntim, Samuel R. Norris, David Goodwin, Jens Breffke, Keana Scott, Li Piin Sung, Treye Thomas, Gregory O. Noonan
Migration evaluation involving nano-enabled food contact materials (FCMs) mostly focus on potential nanoparticle release from new unused products. This may not represent consumer use practices encountered by the FCMs in their lifecycle. In order to

Guest Editorial Open Discussion of Robot Grasping Benchmarks, Protocols and Metrics

October 15, 2018
Author(s)
Jeffrey Mahler, Rob Platt, Alberto Rodriguez, Matei Ciocarlie, Aaron Dollar, Renaud Detry, Maximo Roa, Holly A. Yanco, Adam Norton, Joseph Falco, Karl Van Wyk, Elena R. Messina, Jurgen Leitner, Oliver Brock, Odhner Lael, Andrey Kurenkov, Matthew Matl, Ken Goldberg
Automated grasping has a long history of research that is increasing due to interest from industry. One Grand Challenge for robotics is Universal Picking: the ability to robustly grasp a broad variety of objects in diverse environments for applications

UMP BUILDER: CAPTURING AND EXCHANGING MANUFACTURING MODELS FOR SUSTAINABILITY

September 26, 2018
Author(s)
William Z. Bernstein, Donald E. Libes, David J. Lechevalier
Targeting the improvement of environmental analysis of manufacturing systems, ASTM 3012-16 provides guidelines for formally characterizing manufacturing processes. However, the difficulty that has arisen in the early use of the standard illustrates the

Benchmarking for keyword extraction methodologies in maintenance work orders

September 24, 2018
Author(s)
Thurston B. Sexton, Michael P. Brundage, Melinda Hodkiewicz, Thomas Smoker
Maintenance has largely remained a human-knowledge centered activity, with the primary records of maintenance activity being text-based maintenance work orders (MWOs) that attempt to encode the diagnostic processes of technicians. However, the bulk of

Advanced Maintenance in Manufacturing: Costs and Benefits

September 23, 2018
Author(s)
Douglas Thomas
The costs of maintenance and the potential effect on maintenance costs from adopting predictive maintenance techniques is not well documented at the national level. A number of data items need to be collected to estimate the costs and losses associated

Calibration and Analysis of Tactile Sensors as Slip Detectors

September 13, 2018
Author(s)
Karl Van Wyk, Joseph A. Falco
The existence of tactile afferents sensitive to slip-related mechanical transients in the human hand augments the robustness of grasping through secondary force modulation protocols. Despite this knowledge and the fact that tactile-based slip detection has

Spatial Dimensions in Atomic Force Microscopy: Instruments, Effects, and Measurements

August 15, 2018
Author(s)
Ronald G. Dixson, Ndubuisi G. Orji, Ichiko Misumi, Gaoliang Dai
Atomic force microscopes (AFMs) are commonly and broadly regarded as being capable of three dimensional imaging. However, conventional AFMs suffer from both significant functional constraints and imaging artifacts that render them less than fully three

Manufacturing USA Annual Report, FY 2017

August 10, 2018
Author(s)
Michael F. Molnar
As required by the Revitalize American Manufacturing and Innovation Act of 2014, this report describes the major accomplishments of Manufacturing USA in FY17. This report documents progresss in meeting the goals of the program as stated in its Strategic

Robotic Grasping and Manipulation Competition: Task Pool

July 15, 2018
Author(s)
Yu Sun, Joseph Falco, Nadia Cheng, Hyouk Ryeol Choi, Erik Engeberg, Nancy Pollard, Maximo Roa, Zeyang Xia
A Robot Grasping and Manipulation Competition was held during IROS 2016. The competition provided a common set of robot tasks for researchers focused on the application of robot systems to compare the performance of hand designs as well as autonomous

System Lifecycle Handler -- Spinning a Digital Thread for Manufacturing

July 11, 2018
Author(s)
Manas Bajaj, Thomas D. Hedberg Jr.
Transforming the manufacturing economy from paper-based information flows to a seamless digital thread across geographically distributed supply chains has the potential to reduce cycle time by 75% and save manufacturers $30 billion annually. The "Digital
