Citation preview. Non Traditional Machining ULTRASONIC MACHINING Definition: Ultrasonic Machining is a non-traditional process, in which abrasives contained in a slurry are driven against the work by a tool oscillating at low amplitude (25-100 microns) and high frequency (15-30 kHz). Process: Ultrasonic machining is a mechanical type non-traditional machining process.
