Abstract (in english)
   Results of measurement of dynamic pressure in the nozzle and force effects of modulated jets are presented together with results obtained in cutting of sandstone and granite samples using water jets modulated by ultrasonic vibration of a tip. The results are compared with those obtained with continuous jets at the same operating parameters. Potential of forced modulation of the jet is discussed.
