The article discusses the features of mathematical modeling of technologies using high-speed water jet (for cutting, piercing, cleaning, including their use in the underwater conditions), as well as features of material destruction under water jet treatment. The physical-mathematical model of the process based on the use of the proposed equations of hydroabrasive suspension state and criteria-based dependencies describing the regularities of the processed material destruction was developed on the example of numerical solving two-dimensional axisymmetric problem of piercing holes in the structures of various materials by hydroabrasive waterjet. The features of the solid material destruction during the formation of a through hole in it under the action of a high-speed water jet are shown. Recommendations on choosing kinematic parameters of the cutting jet for different types of waterjet/hydrodynamic machining are given.
