The high-frequency power supply activates the stack of the magnetostrictive material which produces longitudinal vibratory motion of the tool. Fresh abrasives cut better and the slurry, therefore, be replaced periodically. 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. Sound is created by waves, or vibrations in the air created by vibrating an object, which then causes the molecules surrounding it to vibrate. The tool used in ultrasonic machining should be such that indentation by abrasive particle, does not leads to brittle fracture of it. It is also known as Ultrasonic impact grinding is an operation that involves a vibrating tool fluctuating the ultrasonic frequencies in order to remove the material from the work piece.
