Cloud-Enabled Prognosis for Manufacturing

June 22, 2015
Author(s)
Robert Gao, Lihui Wang, Roberto Teti, David Dornfeld, Soundar Kumara, Masahiko Mori, Moneer Helu
Advanced manufacturing depends on the timely acquisition, distribution, and utilization of information from machines and processes across spatial boundaries for improved accuracy and reliability in predicting resource needs and allocation, maintenance

A Generalized Data-Driven Energy Prediction Model with Uncertainty for a Milling Machine Tool using Gaussian Process

June 8, 2015
Author(s)
Jinkyoo Park, Raunak Bhinge, Nishant Biswas, Amrita Srinivasan, Kincho H. Law, David Dornfeld, Moneer Helu, Sudarsan Rachuri
Using a machine learning approach, this study investigates the effects of machining parameters on the energy consumption of a milling machine tool, which would allow selection of optimal operational strategies to machine a part with the minimum energy

Automated Guided Vehicle Bumper Test Method Development

June 2, 2015
Author(s)
Richard J. Norcross, Roger V. Bostelman, Joseph A. Falco
The National Institute of Standards and Technology (NIST) is developing test methods for contact bumpers used on Automated Guided Vehicles (AGVs) as basis for safety standards. This paper describes proposed test methods, force measurements for contact

Applied Force-based Multi-Fingered Grasping and Manipulation Control

May 30, 2015
Author(s)
Karl Van Wyk
This work presents experimental results on a recently developed manipulation controller applied to a multi-fingered robotic hand to execute both grasping and manipulation tasks. The active control strategy was applied to a three-fingered, seven degree of

A Framework to Canonicalize Manufacturing Service Capability Models

May 15, 2015
Author(s)
Boonserm Kulvatunyou, Yunsu Lee, Nenad Ivezic, Yun Peng
The ability to share precise models of suppliers’ manufacturing service capability (MSC) information is necessary to develop reliable methods that enable Original Equipment Manufacturers (OEMs) to efficiently configure agile and responsive supply chains

Navigation Performance Evaluation for Automated Guided Vehicles

May 12, 2015
Author(s)
Roger V. Bostelman, Tsai Hong Hong, Geraldine S. Cheok
Automatic guided vehicles (AGVs), an industrial form of mobile robot, typically navigate using a central computer commanding AGV movement on predefined paths. Although, how well they follow these paths is less defined in research articles and their

Literature Review of Mobile Robots for Manufacturing

May 6, 2015
Author(s)
Michael O. Shneier, Roger V. Bostelman
Mobile robots are devices that can move autonomously to accomplish their goals. This paper provides a review of such robots, mainly oriented towards manufacturing applications. It describes the kinds of mobile robots that are used and what criteria are

Post-process machining of additive manufactured stainless steel

April 29, 2015
Author(s)
Brandon M. Lane, Shawn P. Moylan, Eric P. Whitenton
Due to the poorer surface finish and geometric accuracy of additive manufactured (AM) parts compared to machined parts, it is inevitable that parts fabricated through AM processes will require post-process machining. This problem was identified early by

Performance Measurement of Mobile Manipulators

April 24, 2015
Author(s)
Roger V. Bostelman, Tsai Hong Hong, Jeremy A. Marvel
This paper describes a concept for measuring the reproducible performance of mobile manipulators to be used for assembly or other similar tasks. An AGV with an onboard robot arm was programmed to repeatedly move to and stop at a novel, reconfigurable

The role of standards in MEMS commercialization

April 1, 2015
Author(s)
Michael Gaitan
For many years, the development, creation and use of standards has played a valuable role in the successful commercialization of products, services and processes that address many industries and many applications. So it is with microelectromechanical

Characterizing Task-Based Human-Robot Collaboration Safety in Manufacturing

February 27, 2015
Author(s)
Jeremy A. Marvel, Joseph A. Falco, Ilari Marstio
A new methodology for describing the safety of human-robot collaborations is presented. Taking a task-based perspective, a risk assessment of a collaborative robot system safety can be evaluated offline during the initial design stages. This risk

Effects of wafer noise on the detection of 20 nm defects using optical volumetric inspection

February 11, 2015
Author(s)
Bryan M. Barnes, Francois R. Goasmat, Martin Y. Sohn, Hui Zhou, Andras Vladar, Richard M. Silver
Patterning imperfections in semiconductor device fabrication may either be noncritical [e.g., line edge roughness (LER)] or critical, such as defects that impact manufacturing yield. As the sizes of the pitches and linewidths decrease in lithography
