  • Determining focusing nozzle wear by measuring AWJ diameter [Elektronski vir]
    Prijatelj, Miha, strojnik ...
    Abrasive water jet (AWJ) cutting is a very versatile technology, but is limited by a relative poor accuracy. The main problem is that the diameter of jet is unknown, as there is no device on the ... market that woul d enable quick and easy measurement of diameter. With such instrument the diameter could be regularly measured, nozzle wear monitored and the offset adjusted. This would greatly improve quality control of the process and accuracy of the cut. This paper investigates the usage of the through beam laser sensor for monitoring jet diameter and nozzle wear. Experiments were conducted on five differently worn nozzles, with two different water pressures, with and without abrasive. Results show that sensor is capable of monitoring the jet diameter and nozzle wear, but is very susceptible to spraying of the jet and abrasive sticking to screens of the sensor. Results also show that jet diameter correlated better with the diameter of focusing nozzle, when taking measurements without the abrasive.
