Welcome to the Advanced Manufacturing Laboratory!
we focus on the scientific investigation of
advanced manufacturing processes to improve
quality and productivity in industry, as well as
advanced robotic techniques for industrial and
health care applications. Much of our work
accomplishes this via laser technologies.
Interface Geometry for Laser Joining of NiTi to
Stainless Steel Wires (2013).
G. Brandal, G. Satoh, Y.L. Yao, S. Naveed
By using a cup and
cone geometry at the interface, the tensile
strength of laser joined nickel titanium and
stainless steel wires can be increased.
Precise heat input is necessary in order to
prevent the formation of brittle intermetallic
Joining of Continuous Glass Fiber Composite
Preforms (2013). H. Tan, Y.L. Yao
A two step laser process is developed to form
fusion bonds between fibers within a single
bundle and between adjacent fiber bundles.
Coupled heat transfer and viscous flow modeling
is carried out to investigate the temperature
and dynamics of the joining process under three
experimentally observed conditions.
of hydrogen on surface texturing and
crystallization of a-S:H thin film irradiated by
excimer laser (2012). H. Wang, F.
Lusquinos, Y.L. Yao
Excimer laser processing of amorphous silicon
thin films produces micron size spikes formation
on its surface, and simultaneous crystallization
occurs in a one-step process. Optical absorption
is enhanced by light trapping via multiple
reflections through the surface geometry
changes, and partial crystallization may
increase the overall stability.
Panjawat Kongsuwan (known as
PK) successfully defended his doctoral
dissertation on May 7, 2014. His
dissertation is entitled “Laser
Induced Modification and Integration of
Glasses.” He invited everyone from AML to a
delicious Thai lunch on May 9 to help him
celebrate and thank everyone for their help
and friendship during his PhD candidacy
Chen and Min Zhang, Visiting Scholars from Laser
Processing Research Center of Soochow
China, have submitted two abstracts to
ICALEO ’14 (International Congress on
Applications of Lasers and Electro-optics).
The titles are “Effects of Laser Radiation
on the Wetting and Diffusion characteristics
of Kovar Alloy on Borosilicate Glass,” and
“Experimental and numerical investigation of
laser forming of closed-cell aluminum foam,”
Prof. Yao and Dakai Bian
participated in the annual retreat of Columbia
University Center for High-Throughput
Minimally-Invasive Radiation Biodosimetry”
held April 24-25, 2014. Prof. Yao was
invited to give a presentation on “Overview
of robotics in biomedicine.” They are part
of the NIH-funded team working on robotized
biodosimetry, led by Prof. David Brenner of
Columbia University Medical Center
Jenny Ardelean and Dakai Bian
started their PhD study with AML in January
2014, after successfully completing their MS
studies by Fall 2013. Jenny has been
working on laser scribing of solar cells and
Dakai on inter-laminar toughening of
Prof. Yao attended the
editors' meeting at IMECE ’13 (International
Mechanical Engineering Congress and
Exhibition) held in San Diago during November
15 to 21. The editors of the
26 ASME transactions exchanged views and
discussed steps moving forward. Prof. Yao
currently serves as the Editor, ASME
Transactions, Journal of Manufacturing
Science and Engineering (11/15/2013).
