Abstract: This paper is dedicated to investigate the abrasive water-jet (AWJ) cuttingparameters of hard-to-cut materials represented by Armox shielding steel plate of 7.6mm thick. Experiments were carried out in machining Armox in order to investigatethe possibility of using the AWJ process for machining process. Process variablessuch as water jet travers speed, water jet pressure, stand-off distance, and abrasiveflow rate have been investigated to study the effect of each on the AWJ cuttingprocess parameters. Cutting parameters such as the profiles of machined surfaces,kerf geometries and material removal rate were investigated.The experimental results indicate that the traverse speed is a significant parameteron the surface roughness. It was also observed that the kerf taper ratio and surfaceroughness increase with increasing traverse speed in chosen conditions. Moreover, itshows that surface roughness, and the material removal rate are widely affected bythe abrasive flow rate. The increase of abrasive flow rate yields the material removalrate but decreases the surface roughness. Stand-off distance and jet pressure almosthad no effect on both surface roughness and material removal rate.
