Design and Analysis of a Novel Sensing Cutting Tool for Precision Turning
Abstract:
In this paper, a novel sensing cutting tool for precision turning is presented, which has a self-sensing function to monitor the cutting force in real-time cutting conditions. The basic idea is the integration of the sensors using piezoelectric film onto the rake face of the tool to measure the main cutting force. Piezoelectric film generates electrical signals according to the piezoelectric effect when it is subjected to small movements, due to the deflection and vibration of the tool during machining operations. The output electrical signal of the piezoelectric film is amplified and capable of transmitting cutting force signals to the measuring system. In particular, the results of a calibration experiment using a dynamometer illustrate the performance of the sensing cutting tool and the relationship between cutting force and electrical signals, which can be used reliably to monitor the cutting force. The paper concludes with further discussions on the potential and application of the smart cutting tool for real-time condition monitoring and adaptive machining purposes.
