Water-jet technologies, based on the use of high-speed jets as cutting tools, are one of the promising directions of the destruction technologies for various materials. Jets’ capability to cut even very strong, anisotropic and composite materials, as well as their high cutting speed, that can be reached without workpiece reaction occurring on the tool, make them attractive from the point of view of their implementation as cutting tools. This paper outlines the methods of materials destruction by means of high-speed cryojet and discusses future areas of its application. The research reveals the main factors and criteria for evaluating the effectiveness of cryojet cutting. Experimental studies of the main factors affecting the cryojet cutting parameters were carried out using a bench unit. As a result of the experimental data analysis, we found the correspondences that can be used for calculating the cryojet cutting of various materials.
