Research Interests

My research interests are centred in dimensional metrology, computer aided design, and manufacturing automation. A variety of Coordinate Measuring Machine (CMM) and CAD/CAM/CAE tools are used in the research. Currently available software includes MATLAB, AutoCAD and Mechanical Desktop, SDRC I-DEAS, MDI ADAMS, the ACIS solid modelling kernel, Origin CheckMate, and the Phar Lap ETS real-time kernel. Computer languages primarily used are Microsoft VisualC++ and VisualBASIC. Computing facilities include a variety of Pentium computers running Window NT 4.0, including Stereo Vision equipped Silicon Graphics 320 workstations.

Projects currently underway include sensor integration with an open architecture CMM motion controller, elevated temperature geometric error compensation, laser digitizing, and reverse engineering.
