Abstract
The interaction between a waterjet without abrasive particles and a workpiece is studied with the objective of understanding the machining mechanism and enhancing the rate. It is shown that the machining mechanism is basicly erosion with material fatigue playing a strong role in making erosion possible. It is also shown that excitation of a bulk, high frequency, (>> 1 MHz), ultrasonic wave in the material is an important part of the fatigue mechanism. The excitation is produced by the microdroplets and small vapor/air cavities, nature of the impinging waterjet. It is also demonstrated experimentally that making the workpiece resonate to the ultrasonic wave to increase the oscillating stress substantially enhances the cutting rate.
