Ultrasonic cutting has applications in many fields and with industries using composite and honeycomb materials such as aeronautics, space, automotive, defence, naval, etc. So how does it work?

Ultrasound is a mechanical vibration similar to that produced by musical instruments. They are called ultrasound because their frequency is above the hearing range of the human ear (greater than 16 kHz).

In an acoustic assembly, these pressure waves are produced by a generator. This sends an alternating current of the same frequency as the converter (or transducer).

Then the converter, which is made of piezoelectric ceramics, transforms this energy into mechanical vibrations.

In ultrasound, a voltage is sent to the ceramic and it lengthens or shortens depending on the polarity of the voltage.

Finally, once the vibration is produced, it is amplified and transmitted to the parts to be cut by the sonotrode.
