Ultrasonic
Machining
Ultrasonic machining (USM)
is a mechanical material removal process
used to erode holes and cavities in hard
or brittle workpieces by using shaped tools,
high frequency mechanical motion, and an
abrasive slurry. . A relatively soft tool
is shaped as desired and vibrated against
the workpiece while a mixture of fine abrasive
and water flows between them. The friction
of the abrasive particles gradually cuts
the workpiece.
Materials such as hardened
steel, carbides, rubies, quartz, diamonds,
and glass can easily be machined by USM.
Ultrasonic machining is able to effectively
machine all materials harder than HRc 40,
whether or not the material is an electrical
conductor or an insulator
