  skos:definition "1. Ultrasonic machining is a subtractive manufacturing process that removes material from the surface of a part through high frequency, low amplitude vibrations of a tool against the material surface in the presence of fine abrasive particles. (Wikipedia). 2. Ultrasonic Machining (USM) is an advanced machining process that harnesses the power of high-frequency mechanical vibrations to remove material from workpieces.
