Transducers

Transducers is a device which converts one form of energy into another form of energy. In ultrasonic machining process it converts the electrical energy into mechanical energy.

Types of  Transducer
 
   The following types of transducers are used in ultrasonic machining process for the production of ultrasonic waves.

1. Magnetostriction transducer.
2. Piezoelectric transducer.

MAGNETOSTRICTION TRANSDUCER

Principle : When a rod of ferromagnetic material such as iron or nickle is kept in a magnetic filed parallel to its length is, the rod suffers a change in length. the change in lrngth in length is independent of the direction of the magnetic field and depends only on the magnitude of the field and nature of the material. this phenomenon is known as Magnetostriction effect.
