Rotary ultrasonic machining (RUM) has been regarded as an effective processing method for hard and brittle materials.
Rotary ultrasonic machining (RUM), regarded as an effective processing method for hard–brittle materials, has been explored in many experimental and theoretical investigations.
Since it was first proposed in the 1960s, RUM has been applied to the machining of many types of materials (e.g., glass, engineering ceramics, silicon carbide, and titanium) [3-5].
