Machining mechanism of metal glass cutting based on ultrasonic vibration tool path

Metallic glass has been widely used in aviation, medical, military, and other fields because of its excellent performance. In view of the poor processability of metallic glass, the introduction of ultrasonic vibration provides a unique idea for it. In order to further explore the influence of ultrasonic vibration on trajectory and machining effect, this paper focuses on the theoretical feasibility of generating a unique type of tool path under different parameter combinations and studies the machining effect of metal glass under this condition. The experimental results show that the frequency coefficient, amplitude, and phase difference are all important parameters that affect the characteristics of tool path and the machining effect of metallic glass. The tool path formed by the appropriate phase difference and frequency coefficient will greatly improve the surface morphology, and the separation characteristics formed under the appropriate parameters can reduce the cutting force by about 50%. In addition, the effect of ultrasonic vibration machining with a frequency coefficient of 2 is the best, the cutting force generated is similar to that of elliptical ultrasonic vibration machining, and the roughness is reduced by nearly 50%. Choosing the appropriate parameters will get the ultrasonic vibration tool path with a positive effect, and will greatly improve the machining quality of metallic glass.
