Experimental Investigation of Effect of Processing Parameters on the Surface Roughness during the Brass Alloy Turning with Abrasive Water Jet
AbstractThis study investigates the impact of processing parameters on the surface roughness in the process of abrasive water jet. The sample was machined using abrasive water jet for four different parameters of Nozzle feed rate (5, 15, 25 and 35 mm/min), abrasive flow rate (100, 150, 200 and 250 g/min), spindle speed (50, 100, 150 and 200 rpm) and nozzle distance (2, 6, 10 and 14 mm). Pump pressure (380 MPa), abrasive size (80 Mesh, in Garnet form), and nozzle diameter (0.75 mm) are kept constant throughout the empirical study. According to the results obtained from the experiment, increasing machining parameters, namely nozzle feed rate and nozzle approach distance, resulted in increased average surface roughness. On the other hand, increased spindle spin and abrasive flow rate result in enhanced average surface roughness (Ra).
