The pressurized high-speed water flows together with the Al2O3 particles forms slurry used in abrasive water jet machining (AWJM) to slice specimens. This approach is particularly appropriate for fragile, soft and strident materials. D3 tool steel used as a sample size of 200 x 200 x 23 mm has excellent strength and is also suitable for high-temperature machining operations. In the present work, the 8 mm diameter hole was created using AWJM. The L27 orthogonal array experiments were conducted with crossover speeds (Ts) 80, 100 and 120 mm / min, abrasive mass flow rate (Af) 250, 325 and 400 (g / min) and a standoff distance (Sod) of 1,1.5 and 2 mm as processing parameters. Optimum parameters have been set from ANOVA to achieve high metal extraction. Optimum Sod, Ts, and Af are 400 g / min, 1.5 mm and 120 mm / min. Experiment number 26 and the 27 processing parameters are the best for the D3 tool steel unit to achieve higher metal extraction.
