The paper examines an analytical model of modulated pulses of a high-speed waterjet with a base frequency for waterjet technology. It required laboratory measurements of fundamental oscillations frequency, its prediction and verification. A hydrodynamic system generates a modulated liquid jet at a certain pressure due to a resonant chamber being integrated into the system. The theoretical model was developed particularly on the basis of a set of dimensions and the used liquid pressure which represent the system. A significant performance improvement was achieved in surface disintegration of material being machined.
