The investigations of the velocity distribution and the cutting capability on the abrasive water jet are carried out. The velocity of the water and the particle in abrasive water jet are measured by PIV and PTV, respectively. In this study, The red and blue flashes from stroboscopes are used for PIV and the jet photographs are taken. Then, the water velocity is obtained after the photographs are processed by PC. The weight distributions of the abrasive water jet are obtained by using the box with various size hole. The cutting capability distributions are obtained by combining the water and particles velocity distributions with the probability density distributions of the jet. As the Result, the peak of the cutting capability is shown not only at the center of the jet but also around the jet.
