Assessing the use of an infrared spectrum hyperpixel array imager to measure temperature during additive and subtractive manufacturing

May 11, 2016

Author(s)

Eric P. Whitenton, Brandon M. Lane, Jarred C. Heigel, Shawn P. Moylan

Accurate non-contact temperature measurement is important to optimize manufacturing processes. This applies to both additive (3D printing) and subtractive (material removal by machining) manufacturing. Performing accurate single wavelength thermography

Optical design and initial Results from NISTs AMMT/TEMPS Facility

May 9, 2016

Author(s)

Steven E. Grantham, Brandon M. Lane, Jorge E. Neira, Sergey Mekhontsev, Leonard M. Hanssen, Mihaela Vlasea

NISTs Physical Measurement and Engineering Laboratories are jointly developing the Additive Manufacturing Measurement Testbed (AMMT)/ Temperature and Emittance of Melts, Powders and Solids (TEMPS) facilities. These facilities will be co-located on an open

Calibration and Measurement Procedures for a High Magnification Thermal Camera

January 8, 2016

Author(s)

Brandon M. Lane, Eric P. Whitenton

Infrared thermography is a relatively mature measurement science, however systematic evaluation of measurement uncertainty for multi-point measurement (an infrared focal plane array) is very limited, or, does not follow uncertainty evaluation guidelines

Development of powder bed fusion additive manufacturing test bed for enhanced real time process control

August 27, 2015

Author(s)

Mihaela L. Vlasea, Brandon M. Lane, Felipe F. Lopez, Sergey Mekhontsev, M A. Donmez

Laser powder bed fusion (PBF) is emerging as the most popular additive manufacturing (AM) method for producing metallic components based on the flexibility in accommodating for a wide range of materials with resulting mechanical properties similar to bulk

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

August 27, 2015

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

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

Measurement Science Needs for Real-time Control of Additive Manufacturing Powder Bed Fusion Processes

March 15, 2015

Author(s)

Mahesh Mani, Brandon M. Lane, M A. Donmez, Shaw C. Feng, Shawn P. Moylan, Ronnie R. Fesperman Jr.

Additive Manufacturing is increasingly used in the development of new products: from conceptual design to functional parts and tooling. However, today, variability in part quality due to inadequate dimensional tolerances, surface roughness, and defects

Thermographic and FE Simulation of the DMLS Process at NIST

February 4, 2015

Author(s)

Brandon M. Lane, Li Ma, Shawn P. Moylan, M A. Donmez, Eric P. Whitenton, Daniel J. Falvey

A major effort of the Measurement Science for Additive Manufacturing Program at NIST is to provide high quality, well-defined temperature measurement of the DMLS process to support and validate multi-physics simulations. However, the dynamic, complex

Fiber Orientation Angle Effects in Machining of Unidirectional CFRP Laminated Composites

July 10, 2014

Author(s)

Vis Madhavan, Gary Lipczynski, Brandon Lane, Eric P. Whitenton

Experiments were carried out at the National Institute of Standards and Technology, in collaboration with The Boeing Company, to obtain force and temperature data as a function of feed, speed, and fiber orientation angle (FOA), for validation of finite

Uncertainty in Measurement of the Maximum Cutting Tool Temperature by Infrared Thermography

June 13, 2014

Author(s)

Brandon M. Lane, Eric P. Whitenton, Viswanathan Madhavan, M A. Donmez

This paper presents an analysis of the uncertainty in measurement of the peak temperature on the side face of a cutting tool by infrared thermography. An analytical method uses the temperature measurement equation to study the uncertainty arising from
