The measurements of the velocities of water and abrasive particles in abrasive waterjet are carried out. Double-exposured photographs of the abrasive waterjet are taken using a red flash and a blue flash. The water velocity is obtained by the PIV method that evaluates the cross-correlations between the red images and the blue images extracted from the photographs. For the measurement of the abrasive particle velocities, PTV method, that traces the movement of each particle in the photograph, is employed. The velocities of water and abrasive particles are successfully measured by this system. The relation between the cutting capability and the kinetic energy of water and abrasive particles are examined. It is also shown that the condition of abrasive waterjet can be classified into three regions in respect to the abrasive flow rate.
