In this study the effect of processing parameters during turning of AISI 1040 steel with abrasive water jet on machining volume and depth of cut. In the study, in order to keep the experiment quantity low, former studies in literature were taken into consideration and therefore experiments were realized with processing parameters and experiences that are most suitable to pre-experiments. In experimental studies pump pressure (350 MPa), abrader dimensions (in garnet form and dimension 80 mesh) and nozzle diameter (1.2 mm) were kept constant. 1040 steel with dimensions of empty set 30 and 240 mm were processed at four different abrader flow rate (50, 150, 250 and 350 gr/min), nozzle distance (2, 5, 8 and 11 mm), nozzle feed rate (5, 15, 25 and 35 mm/min) and lathe chuck revolutions (25, 50, 75 and 100 rpm). According to the findings the most highly material removal rate of 5 mm / min nozzle feed rate 1387.25 mm(3) in the amount has been achieved. The maximum depths of cut 0.94 mm spindle speed of 100 rpm were obtained.
