U radu su prikazani i objašnjeni postupci rezanja mlazom vode, a to su čisti vodeni mlaz i vodno-abrazivni rezni mlaz. Navedeni su tehnološki zahtjevi kod primjene tehnologije rezanja mlazom vode. Pojedina poglavlja u radu objašnjavaju načine stvaranja tlaka vode i tehnologiju nastanka vodno-abrazivnog mlaza, uz objašnjenje miješanja vodenog mlaza i abrazivnih čestica. Eksperimentalnim dijelom se objasnio utjecaj pojedinih parametara rezanja (tlaka, brzine rezanja i veličine abrazivnih zrna) na rezultat rezanja, odnosno hrapavost površine rezanja i oštećenja površine.

The paper presents and explains the procedures of cutting jet of water, such as pure water jet and abrasive water-jet cutting. These are the technological requirements for the application of technology of cutting the tap. Individual chapters of the paper explains the ways to create pressure water technology and the emergence of a water-abrasive jet, with an explanation of mixing water jet and abrasive particles. Experimental partly explain the impact of certain cutting parameters (pressure, cutting speed and size of abrasive grains) on the result of cutting or cutting surface roughness and surface damage.
