Abstract
A high speed, high precision, high repeatability serial sectioning method for 3-D reconstruction of microstructure specimen is disclosed. The invention employs high-precision motorized metallographic polishing, viewing and computer controlled digital imaging of microstructure sections of a pre-selected pattern for 3-D microstructure reconstruction. The microstructure specimens are transferred throughout by a robotic manipulator arm, which provides greater precision and speed and serial-sectioning process control software provides control. The 3-D reconstruction of the invention can be analyzed in real time and can be accomplished in a matter of hours.
