In order to maximum the productivity of water jet cutting and cleaning. The determination of the particle velocities at different conditions of water jet formation is essential to the establishment of a prediction model of the cutting results.

The Study is Intended to develop an interface between Laser Transit Anemometer (LTA) and IBM PC for velocity field measurement of the jet by automation of technology design. To achieve this, a turbo basic program is developed to link LTA, counter processor, NIC-320 nicolet oscilloscope and IBM PC together for improve the efficiency and quality of velocity's measurement of the jet.

Because of computer speed, memory, and computational capabilities, a new system is developed by used LTA to measure the velocities of the particles entrained in the water jet automatically and the technique is validated. The result compare with manual measurement that increase the efficiency and accuracy of water jet velocity measurement along the down stream by 80%.
