Abstract
A new procedure is proposed to extend tool life. The new procedure use s a Smart Workpiece Holder (SWH), which monitors the cutting force and reduces the metal removal rate when it predicts tool breakage possibi lity. The response includes a quick move in the opposite of the feed d irection by using a piezoelectric actuator and by reducing the feed ra te. The proposed system was tested with mild steel and aluminum workpi eces. Based on the experimental results, better than 50% of the tool b reakage cases could be predicted and tool life can be increased more t han 30%. (C) 1998 Elsevier Science Ltd. All rights reserved.
