| Abstract: | The monitoring of cutting force has a great significance in promotion and processing of ultrasonic vibration cutting technology in vibration cutting process.On the basis of the research on the relationship among cutting force,transducer electrical impedance and load,a new monitoring method which uses the transducer electrical properties to reflect the cutting force of ultrasonic elliptic vibration cutting is proposed,and a transducer electrical properties measurement system is designed.The feasibility of cutting force monitoring based on piezoelectric transducer electrical properties is proved by the cutting experiments. |
