Ultrasonic machining is a kind of grinding method. It is also called as ultrasonic grinding. The term ultrasonic is used to describe a vibratory wave of frequency above that of the upper frequency limit of the human ear, i.e. generally above 16 KHz. The device for converting any type of energy into ultrasonic waves is ultrasonic transducer.
