    • 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 ...

    • 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 ...
