| Abstract | ||
| ABSTRACT It is well known that abrasive water jet (AWJ) was developed as a kind of highdensity energy processing technologies. AWJ is used to obtain cutting quality of various materials such as metal, ceramics, glass and composite materials within a short manufacturing time because of the characteristics of heatless and noncontact processing. However, surface roughness and dimension error like round, burr, taper depend on the cutting conditions such as pump pressure, cutting speed, orifice diameter, standoff distance, abrasive flow rate and work piece. In this paper, the effect of the shape of mixing chamber on surface quality is studied. Parabolic mixing chamber is proposed and performance is compared to that of cylindrical mixing chamber by experiment. The surface roughness was improving 0.15 to 2.29 and the taper angle was improving 0.0716° to 0.143° by parabolic mixing chamber. | ||
