Research Interests

My research interests are in the area of CAD/CAM/CAI (Computer-Aided Design, Manufacturing, and Inspection) with emphasis on:

  • Scanning-derived geometric modeling
  • Three-axis and five-axis CNC machining
  • 3D laser scanning and computational/coordinate metrology

Current Research Work

  • Triangle mesh based geometric modeling and design
  • Generalized CNC simulation and verification
  • Optimal tool path generation in multi-axis sculptured surface machining
  • Automatic removal of outliers in 3D laser scanned point clouds
  • Precision inspection of complex shaped parts using 3D laser scanning
