The pressurized high-speed water flows together with the Al 2 O 3 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

Optimum parameters have been set from ANOVA to achieve high metal extraction. Optimum Sod, T s , and A f 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.
