This Special Issue on Smart Manufacturing PHM contains six outstanding technical papers and one communication that collectively present a diverse range of research and practical application topics within the field of Smart Manufacturing PHM.

Thermographic Measurements of the Commercial Laser Powder Bed Fusion Process at NIST

December 5, 2016
Author(s)
Brandon M. Lane, Shawn P. Moylan, Eric P. Whitenton, Li Ma
Measurement of the high-temperature melt pool region in the laser powder bed fusion (L-PBF) process is a primary focus of researchers to further understand the dynamic physics of the heating, melting, adhesion, and cooling which define this commercially

An Open Web-Based Repository for Capturing Manufacturing Process Information

December 1, 2016
Author(s)
William Z. Bernstein, Mahesh Mani, Katherine C. Morris, Kevin W. Lyons, Bjoern J. Johansson
With recent progress in developing more effective models for representing manufacturing processes, this paper presents an approach towards an open web-based repository for storing manufacturing process information. The repository is envisioned to include

Membrane-Based Environmental Cells for SEM in Liquids

December 1, 2016
Author(s)
Andrei A. Kolmakov
Environmental electron microscopy and Scanning Electron Microscopy (SEM) in liquids are among the most active research areas in modern electron microscopy and spectroscopy. Research interest in these techniques is broad as they are enabling the nanoscale

Lets Talk, Robots

November 21, 2016
Author(s)
Craig I. Schlenoff
This is a short article for Scientific Computing Magazine, at the request of the editor, that describes the IEEE 1872 IEEE Standard Ontologies for Robotics and Automation standard.

Survey and New Directions for Physics-Based Attack Detection in Control Systems

November 21, 2016
Author(s)
David Urbina, Jairo Giraldo, Alvaro Cardenas, Junia Valente, Mustafa Faisal, Niles O. Tippenhauer, Justin Ruths, Rick Candell, Heinrik Sandberg
Monitoring the "physics" of control systems to detect attacks is a growing area of research. In its basic form a security monitor creates time-series models of sensor readings for an industrial control system and identifies anomalies in these measurements

Charter of the Institute Directors Council: Manufacturing USA

November 18, 2016
Author(s)
Craig Blue, Larry Brown, Yoel Fink, Nick Justice, Michael Liehr, Tom McDermott, Ed Morris, Shawn P. Moylan
The Manufacturing USA program is composed of the collective of all of the manufacturing innovation institutes and a supporting Network. The Network serves the Institutes, the Institutes connect through the Network, and the Program serves the Nation.

Planning Algorithms for Multi-Setup Multi-Pass Robotic Cleaning with Oscillatory Moving Tools

November 17, 2016
Author(s)
Ariyan M. Kabir, Joshua D. Langsfeld, Shaurya Shriyam, Vinaichandra S. Rachakonda, Cunbo Zhuang, Krishnanand N. Kaipa, Jeremy Marvel, Satyandra K. Gupta
We describe planning algorithms for cleaning stains on a curved object. Removing the stain may require multiple reorientations of the part and some portions of the stain may require multiple cleaning passes. The experimental setup involves two robot arms

Sensor Calibration and Registration for Mobile Manipulators

November 16, 2016
Author(s)
Steven Legowik, Roger V. Bostelman, Tsai H. Hong
This paper describes the methods used to register a mobile manipulator to a workstation to perform assembly tasks. The nonlinear, least square model of the system is formulated and Ceres Solver[1] is used to compute the position of the robot arm relative

Fabrication, Testing and Simulation of All Solid State Three Dimensional Li-ion Batteries

November 10, 2016
Author(s)
Alec Talin, Dimitry Ruzmetov, Andrei Kolmakov, Kim McKelvey, N Ware, Farid El Gabaly, Bruce Dunn, Henry White
In this paper we demonstrate fully-functional 3D SSLIBs fabricated using materials and thin film deposition methods compatible with semiconductor device processing. These 3D SSLIBs consist of conical or cylindrical Si microcolumns onto which layers

Towards a generalized energy prediction model for machine tools

November 9, 2016
Author(s)
Raunak Bhinge, Jinkyoo Park, Kincho H. Law, David Dornfeld, Moneer Helu, Sudarsan Rachuri
Energy prediction of machine tools can deliver many advantages to a manufacturing enterprise, ranging from energy-efficient process planning to machine tool monitoring. Physics-based energy prediction models have been proposed in the past to understand the

A Tetherless, Absolute-Time Channel Sounder, Processing, and Results for a Complex Environment

November 4, 2016
Author(s)
David R. Novotny, Alexandra E. Curtin, Catherine A. Remley, Peter B. Papazian, Jeanne T. Quimby, Richard Candell
we present a channel sounder that can operate without a tether and still maintain an absolute time reference between the source and receiver. Based on a sliding correlator, with synchronized rubidium clocks to generate phase references for the up- and down
