AbstractAISI 304 stainless steel accounts for approximately 50% of the world's stainless-steel production and consumption. It is important to improve the machinability properties of stainless steels due to the intensive use in the industry. In this study, the effect of machining parameters on surface roughness was investigated in water jet turning of AISI 304 material. The test parameters were determined as nozzle feed rate, abrasive flow rate, turning speed of the chuck and nozzle distance. During the experimental study, the pump pressure (380 MPa), the abrasive size (80 Mesh in Garnet form) and the nozzle diameter (0.75 mm) were kept constant. According to the experimental results, the surface roughness decreased as the turning speed and the abrasive flow rate increased. On the other hand, the surface roughness value increased as the nozzle feed rate and nozzle distance increased.
