Turning of (Cu-Cr-Zr) alloy with abrasive water jet

Abstract

In this research, the effect of the processing parameters on surface roughness during the turning of (Cu-Cr-Zr) alloy with abrasive water jet was studied. In the experimental studies, (Cu-Cr-Zr) alloy, ∅30 and 240 mm in size, was processed with abrasive water. In the experiment, pump pressure was 350 MPa, in the form of garnet abrasive and 80 mesh in size and nozzle diameter were kept constant at 1.2 mm. In addition to that in the parameters of nozzle feed rates (10, 15, 20 and 25 mm/min), abrasive flow rates (50, 150, 250 and 350 gr/min) and nozzle distances (2, 5, 8, 11 mm) were used in the tests. According to the results of the experiment, the increase in nozzle feed rate and nozzle distance lead to increase in average surface roughness. On the other hand, the increase in the number of turning speed and abrasive flow rate lead to decrease in average surface roughness. Average surface roughness was measured between 2.5 and 5.5 μm. © BHR Group 2012 Water Jetting 21.
