Visualization of Water Jet Cutting by Means of Ultrasonic Waves

摘要

It has been recognized from many investigations on water jet cutting mechanism that visualiza- tion of a cutting front is very effective to deepen understanding of the mechanism. However, an in process visualization method, especially those applicable to opaque materials such as metals has not been established even now. This paper newly proposes a method of visualization of cutting front using ultrasonic waves. Several experiments have shown that in-process visualization of a shape of the cutting front, inclination and profile waviness of cutting surface can be realized using the proposed method. Furthermore, this paper also proposes a water jet cutting process model based on detail analyses of visualization results.
