Area where LDVs are focused on an ultra-high-speed spin- dle (NAMRC paper by Nahata, Anandan and Ozdoganlar).
A NAMRC paper by Suresh Kumar Ramasamy (Hutchin-
son Technology, Carver, MN) and Jayaraman Raju (University of North Carolina-Charlotte) looks at multiscale data fusion as a cost-effective tool to measure and characterize new engi- neered surfaces for microelectromechanical systems (MEMS) and microfluidics. A performance study was conducted on a wide range of surface samples, and it was shown that Regional Edge Intensity (REI) is the preferred fusion method
for surface metrology datasets, and Regional Energy (RE) is the second preferred method, when single-scale performance metrics are considered. This paper is in press for the Journal of Manufacturing Systems (
http://tinyurl.com/NAMRC-Raju). A laser Doppler vibrometer (LDV) based technique to accurately measure the radial error motions of a miniature ultra-high-speed spindle is the subject of a NAMRC paper by Sudhanshu Nahata, K. Prashanth Anandan and O. Burak Oz- doganlar of Carnegie Mellon University (Pittsburgh). The valid- ity of the multi-orientation implementation is concluded from the fact that the artifact form error obtained at the two spindle speeds (50 krpm and 80 krpm) was nearly the same, with the radial spindle error motions being considerably different.
