In the present paper, the authors developed a physic mathematical model of cutting sheet material and presented the results of a parametric study of the cutting material’s efficient with a hydro and hydroabrasive jet of AMg6 parts with a thickness of 10 mm, depending on its speed and abrasive mass concentration that were obtained using the ANSYS/AUTODYN software package. The authors established that by increasing the speed of the jet without abrasive to 1180 m/s, it is possible to increase the cutting efficiency, estimated by the material flashing time, to a value comparable to its value during processing with a hydroabrasive jet at a speed of 800 m/s and a garnet sand mass concentration of 5%, which leads to an increase in the resource of the stream forming path. The paper is concerned that the necessary increase in speed, realized by increasing the pressure at the inlet of the installation, can be achieved with the help of modern pumps.
