Inconel Alloy 718 super alloy was machined using
abrasive water jet (AWJ) in this study. 
Following the cutting process, average surface roughness (Ra µm) and
material removal rate (MRR) were investigated and operating parameters were
optimized using Taguchi method. Among the machining parameters were pump
pressure (PP) (200, 350 MPa), nozzle feed rate (NFR) (5, 105 and 205 mm/min);
abrasive flow rate (AFR) (50, 200 and 350 g/min); spindle speed (SS) (25, 50
and 75 RPM) and standoff distance (SOD) (2, 8 and 14 mm).  Taguchi L18 (21 x34) orthogonal factorial
experiment organization is adopted as experiment design. The effect of
parameters on Ra and depth of cut (DoC) was investigated statistically using
the outcomes of the variance analysis and S/N rates.  As a result of the empirical studies, PP
proved to have the highest effect on Ra by 42.35%. On the other hand, NFR
proved to have the highest effect on DoC by 72.85%. Increasing SS has improved
Ra value while increasing DoC.
