It has been determined that the clean waterjet cutting tends to separate soft materials such as plastic, foil, foam or paper, as well as food. Unlike the pure waterjet cutting, the abrasive cutting is used for hard materials such as steel, ceramics, glass. The optimal pressure for material processing has been calculated.

If we increase cutting values, then the tool life is reduced and that leads to higher tool costs. With universal high-performance machines we cannot save costs for tools (we can only save machine tool costs).

For this purpose, the hardness formed during the cutting of HARDOX-500 steel has been examined using the mathematical modeling of multi-factor experiments. As a result, a full-factorial mathematical regression equation has been derived based on the dependence on waterjet pressure (P), abrasive particle consumption (Q) and longitudinal feed of the nozzle (S_long). The conducted studies revealed that the hardness values on the surface of the cut area can vary significantly during hydro-abrasive cutting of the selected steel workpieces. Specifically, an increase in the longitudinal feed rate of the nozzle, the consumption of abrasive particles, and the pressure of the waterjet leads to an increase in the hardness of the cut surface. Among these factors, the longitudinal feed of the nozzle has the most significant impact on surface hardness. Furthermore, the product of waterjet pressure and longitudinal feed (X_2 X_3), as well as the combined effect of all three input parameters (X_1 X_2 X_3), are influential factors contributing to the increase in hardness.
