Comparison of the disintegration abilities of modulated and continuous water jets

Original language description

This study investigated the erosion phenomena of a high-speed modulated water jet (MWJ) and a continuous water jet (CWJ) during jet–material interaction. The disintegration abilities of self-excited and continuous water jets were compared. The erosion abilities of the MWJ and CWJ for two levels of hydraulic powers (26 and 72 kW) on the aluminum alloy EN AW-6060 were tested. The CWJ was generated using a StoneAge 0.069″ nozzle with a circular orifice having a diameter of 1.75 mm, and the MWJ was generated by a nozzle with a rectangular orifice having dimensions of 1.5 mm × 1.5 mm. Owing to the asymmetrical MWJ profile, two different alignments of jet position (0° and 90°) with respect to the direction of nozzle travel were examined. A six-axis industrial robot equipped with both nozzles ensured the movement of the particular trajectory with a traverse speed of 1 mm/s. An optimal standoff distance was observed for all tested pressures of the given hydraulic powers with respect to the nozzle and material position. High-pressure flow diagnostic sensors were used to accurately adjust the hydraulic power of the tested operating conditions. A total of 29 samples with dimensions of 100 mm × 50 mm × 20 mm were investigated during experimental testing. Each erosion test was repeated three times. Subsequently, the eroded groove profiles were studied using a MicroProf FRT optical profilometer. Basic parameters such as average material groove depth, groove width, and material removal rate were statistically analyzed. The irregularities and specific surface characteristics of the eroded grooves were examined using scanning electron microscopy. It was observed that using MWJ, a four-times higher erosion rate of material removal can be achieved compared with standard CWJ using the same technological conditions. The details of the experiments are presented in this paper
