Abstract: A method for liquid-jet cutting, including a compressor unit (3), which compresses a liquid for producing a liquid jet, and a nozzle (10), which is connected to the compressor unit (3) and which has an outlet opening (11), through which the compressed liquid exits in the form of a liquid jet (14). The one flow of the compressed liquid to the outlet opening (11) is interrupted or enabled by an interrupting unit (8). The following steps are performed: compressing the liquid by the compressor unit (3), moving the outlet opening (11) toward a workpiece (15) to be processed until a processing distance (d) is reached, alternately enabling and interrupting the liquid jet (14) by the interrupting unit (8), wherein simultaneously the nozzle is moved in relation to the workpiece in a processing direction (22) and the pulse duration (tp; tp1; tp2) of the liquid jet is less than 1000 ?s.

Abstract: The invention relates to a liquid jet cutting method using a compressor unit (3) that comprises a liquid for generating a liquid jet and using a nozzle (10) that is connected to the compressor unit (3) and has an outlet opening (11) through which the compressed liquid exits in the form of a liquid jet (14). The flow of the compressed liquid to the outlet opening (11) can be interrupted or released by means of an interruption unit (8). The method has the following steps: compressing the liquid by means of the compressor unit (3), moving the outlet opening (11) closer to a workpiece (15) to be machined up to a machining distance (d), and alternatively releasing and interrupting the liquid jet (14) by means of the interruption unit (8), wherein the nozzle is simultaneously moved relative to the workpiece in a machining direction (22), and the machining angle between the workpiece surface (115) and the liquid jet (14) is less than 90°.
