The ultrasonic-machining process utilizes the plastic deformation of metal for the tool and the brittleness of the workpiece. The tool vibrates and pushes down on the abrasive slurry containing grains until the grains impact the brittle workpiece. During this operation, the workpiece is broken down while the tool bends very slightly.

The process is configured into two main types (Fig. 1a–b) depending upon how the force is transferred from the vibrating tool to the work surface.If the transfer of vibration energy is achieved by introducing a liquid containing abrasive grits in the gap between the tool and work surface, the process is called "ultrasonic impact grinding" or simply "ultrasonic machining."

In this machining, a chemically reactive abrasive fluid is used for the machining process. • Rotary Ultrasonic vibration machining (RUM): In RUM, a vertically rotating tool is allowed to revolve about the axis of the sonotrode. The surface of the tool is impregnated with diamonds that is used to grind down the surface of the work-piece.

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 specific frequency, an abrasive slurry, usually a mixture of abrasive grains and water of fixed ratio (20% – 30%), flows under pressure through the tool-workpiece interface.
