摘要

This paper reports the innovative design of three-degree-of-freedom ultrasonic elliptical vibration tool holder (3-DOF UEVTH) based on coupled resonance mode. Ultrasonic elliptical vibration cutting technology is a kind of ultra-precision machining technology developed in recent years, and the structure design of its machining device is one of the difficulties in the current research. By analyzing the existing ultrasonic elliptical vibration cutting devices, a new three-dimensional ultrasonic elliptical vibration tool holder based on piezoelectric transducer is designed, and the modal analysis of the three-dimensional ultrasonic elliptical vibration tool holder is carried out by using the finite element analysis tool. it is determined that it has longitudinal vibration mode and bending vibration mode, and the resonance frequency of longitudinal vibration is very close to that of bending vibration by harmonic response analysis, which verifies the feasibility of the design.
