materjalide töötlemine (lõikamine) kõrgkiiruselist (kuni 900 m/s) ja kitsast (läbimõõduga 0,1-0,4 mm) veejuga kasutades (vrd abrasiiv-veejugatöötlus), a hydrodynamic machining process that uses a high-velocity stream of water as a cutting tool; this process is limited to the cutting of nonmetallic materials when the yet stream consists solely of water (compare: abrasive water-jet machining)
