The main aim of this experimental investigation is evaluating the volume of material removed from stainless steel AISI 304 by using an ultrasonic pulsating water jet. For this experimental investigation, a central five-level composite design of experiment was chosen. Factors of interaction were pressure p = 33; 40; 50; 60 and 67 MPa, feed speed rate v = 0.3; 0.5; 0.8; 1.1 and 1.3 mm/s, and round nozzle diameter d = 0.889; 1.067; 1.321; 1.575; 1.753 mm. All samples were weighed and later processed by the Minitab. The results of the investigation show that the combination of higher pressure p [MPa], larger round nozzle diameter d [mm] and lower feed speed rate v [mm/s] incre– ases the volume of stainless steel removal Δ [g].
