    • Comparative Assessment of the Transient Temperature Response during Single Discharge Machining by Micro-EDM and LIP-MM Processes 

      Saxena, Ishan; Li, Xiaochun; Kornel, Ehmann (9th International Conference on MicroManufacturing (ICOMM 2014), 2014-03-25)
      The micro-EDM is a well-established subtractive type of micro-manufacturing process and has been at the center of research for the last 15 years. The laser induced plasma micro-machining (LIP-MM) is a novel multimaterial ...
    • Effect of Thermocapillary Flow on the Surface Profile in Pulsed Laser Micro Polishing 

      Ma, Chao; Vadali, Madhu; Duffie, Neil A.; Pfefferkorn, Frank E.; Li, Xiaochun (8th International Conference on MicroManufacturing (ICOMM 2013), 2013-03-25)
      The objective of this paper is to understand and predict how surface profiles produced by thermocapillary flow change with material properties and process parameters during pulsed laser micro polishing. Thermocapillary ...
    • Effects of Laser Pulse Duration on Pulse Laser Micro Polishing 

      Vadali, Madhu; Ma, Chao; Duffie, Neil A.; Li, Xiaochun; Pfefferkorn, Frank E. (7th International Conference on MicroManufacturing (ICOMM 2012), 2012-03-12)
      Pulsed laser micro polishing (PL?P) has been shown to be an effective method of polishing micro metallic parts whose surface roughness can approach the feature size. This paper will describe the influence of laser pulse ...
    • Irregular, Adaptive Scan Trajectories for Pulsed Laser Micro Polishing 

      Vadali, Madhu; Ma, Chao; Li, Xiaochun; Duffie, Neil A.; Pfefferkorn, Frank E. (8th International Conference on MicroManufacturing (ICOMM 2013), 2013-03-25)
      The objective of this work is to generate irregular, smooth, adaptive laser scan trajectories for pulsed laser micro polishing (PL?P). Traditionally PL?P, like other surface finishing processes has used zigzag scan ...
    • Laser Polishing of Micro-Machined Microfluidic Molds 

      Smith, Bryce B.; Wolf, Dennis M.; Turner, Kevin T.; Duffie, Neil A.; Li, Xiaochun; Pfefferkorn, Frank E. (5th International Conference on MicroManufacturing (ICOMM 2010), 2010-04-05)
      The objective of this paper is to explore the effective-ness of using a pulsed 1064 nm wavelength Nd:YAG laser to polish micro-machined metal molds. Polishing is desired to reduce the surface roughness of Polydimethylsiloxane ...
    • Pulsed Laser Micro Polishing: Surface Prediction Model 

      Vadali, Madhu; Ma, Chao; Duffie, Neil A.; Li, Xiaochun; Pfefferkorn, Frank E. (6th Annual Conference on MicroManufacturing (ICOMM 2011), 2011-03-07)
      This project is focused on developing physics-based models to predict the outcome of pulsed laser micro polishing (PL�P). Perry et al. have modeled PL�P as oscillations of capillary waves with damping resulting from the ...
