In ultrasonic machining, a tool vibrating longitudinally at 20 kHz to 30 kHz with an amplitude between 0.01 mm to 0.06 mm is pressed onto the work surface with a light force. As the tool vibrates with a …

2.1 Single-grain trajectory. The key principles behind the longitudinal–torsional composite ultrasonic-assisted mill-grinding process are shown in Fig. 1(a). The motion of the grinding wheel is described by a rotational motion, feed motion, axial ultrasonic vibrational, and circumferential ultrasonic vibration.

An ultrasonic grinding mill was designed. It permits to carry out simultaneously intensive ultrasonic, mechanical and cavitation treatments of powder materials that in turn leads to sharp acceleration of diffusion, mass-transfer processes and solid phase reactions due to crystallite size and structure changing.

Ultrasonic additive manufacturing (UAM), also known as ultrasonic consolidation (UC), is a hybrid sheet lamination process that brings together ultrasonic welding and computer …
