| Abstract: | A new procedure is proposed to extend tool life. The new procedure uses a Smart Workpiece Holder (SWH), which monitors the cutting force and reduces the metal removal rate when it predicts tool breakage possibility. The response includes a quick move in the opposite of the feed direction by using a piezo-electric actuator and by reducing the feed rate. The proposed system was tested with mild steel and aluminum workpieces. Based on the experimental results, better than 50% of the tool breakage cases could be predicted and tool life can be increased more than 30%. |
