Design of an Ultrasonic Pointed Cutter

Abstract:

Ultrasonic cutting technique is an advanced processing method of cutting honeycomb materials. An ultrasonic pointed cutter was designed. Combined with the principle of ultrasonic cutting, the mathematical model of the tool was established. Modal analysis of the tool was calculated with the finite element software to study the effects of tool geometry on the natural frequency. The results show that the natural frequency increases as the tool thickness increases, but it decreases as the tool length increases. And it obtained the modal shapes and natural frequencies of the tool which meet design requirements. The optimal geometry of the tool was also determined. Finally, it verified the rationality of tool design by amplitude measurement experiment of the tool.
