摘要: 振动切削加工过程中监测切削力对于超声振动切削技术的推广和加工生产具有重要意义。本文在换能器驱动技术分析的基础上,通过研究超声椭圆振动切削过程中切削力、换能器电学阻抗与负载的变化关系,提出了一种利用换能器电学特性来判断超声椭圆振动切削力的新监测方法,并设计了一套换能器电学参数测量系统。通过大量的切削实验,验证了基于换能器电学特性的振动切削力监测方法的可行性。

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.
