Effects of Simultaneous Ultrasonic Vibration of the Tool and the Workpiece in Ultrasonic Assisted EDM

In this paper, a new, proposed, ultrasonic assisted EDM is investigated. The problem is assumed to be axisymmetric. Results show that simultaneous ultrasonic vibration of the tool and the workpiece increases the lifetime of the bubble and its growth and collapse rates. Results also show that simulta...

Description
Summary:In this paper, a new, proposed, ultrasonic assisted EDM is investigated. The problem is assumed to be axisymmetric. Results show that simultaneous ultrasonic vibration of the tool and the workpiece increases the lifetime of the bubble and its growth and collapse rates. Results also show that simultaneous ultrasonic vibration of the tool and the workpiece causes the vapor bubble to expand to a larger maximum volume. This, in turn, causes the pressure inside the vapor bubble to drop to a lower minimum volume, facilitates the ejection of the molten material from the crater, and enhances the material removal rate.
