  • Recently, manufacturing work has been transformed to advanced technology intensive form from mass production with a little items required in the past. It was demanded that superior workpiece surface integrity. However, the study of ductile mode machining was proceeded actively.In this paper, it is developed Ultra-Micro Indentation Device using the PZT actuator. Experimentally, by using theUltra-Micro Indentation device, the micro fracture behavior of the silicon wafer was invesgated. It was possible that ductile-brittle transition point in ultimate surface of brittle material can be detected by adding an acoustic emission sensor system to the Ultra-Micro Indentation apparatus.
