The paper deals with increasing the feed speed influence on the quality of machined surface of work-piece using the technology of abrasive water jet turning, and the proposal of on-line monitoring of the process using acoustic emission. Titanium materials of degree 3 (diameter of work-piece dw = 46 mm) and Incoloy 925 alloy (diameter of workpiece dw=53 mm. The experiment was implemented using continuous abrasive water jet (Australian garnet, MESH = 80) with working water pressure p = 400 MPa. Rotation speed was the same for both experiments, and was adjusted to the value n = 34 RPM. Feed speed (vf = 1.5 – 7.5 mm.min-1) was gradually changed at the constant cut depth ap = 2 mm. Visualization of the machined surface was implemented using the Olympus LEXT OLS 3100 laser co focal microscope. Roughness parameters (Ra, Rq, Rz) were measured using the MicroPro FRT optical profilometer.
