Ultrasonic machining is a low material removal rate (MRR), loose abrasive machining process in which the mirror image of a shaped tool can be created in hard, brittle materials. Material removal is achieved by the direct and indirect hammering of abrasive particles against a workpiece by means of an ultrasonically vibrating tool.

Ultrasonic machining (USM), using shaped tools, high-frequency mechanical motion, and abrasive slurry is effective for materials of extreme hardness or brittleness. Unlike other nonconventional machining methods such as laser beam and electrical discharge machining, USM does not thermally damage the workpiece.

One emerging technology that is receiving notable attention is ultrasonic-assisted machining, or—more strictly speaking—rotary ultrasonic vibration-assisted machining, sometimes referred to by a simple acronym, UAM. Wikipedia has published the acronym RUM in

It also causes run-out and vibration that reduces the precision of the machining effort, while reducing tool and spindle life. It is an unfortunately common problem in machining. Beyond this, high-speed machining (in excess of 20,000 RPMs) is common in manufacturing aerospace, medical, and other precision parts, when machining exotic alloys and harder metals like titanium.
