A Novel Cutting Technology for Chemical Environments Using Pulsed Abrasive Water Jet

Abstract

This paper aims to apply the self-excited oscillation pulsed (SEOP) water jet to metal cutting in chemical environments. For this purpose, the impact force of the water jet was compared with that of continuous jet under different flow pressures and at different target distances. The results show that the impact force of pulsed water jet was much greater than that of the continuous jet. After that, some abrasives were introduced to the pulsed water jet to enhance its cutting ability. Following this train of thought, a portable cutting system was assembled and examined in details. It was proved that the portable cutting system was convenient and effective for chemical environments.
