Mechanical engineering and robotics N2 - In the article, the microhardness of the surfaces of the 30 mm long, 20 mm wide, and15 mm high rectangular material made on the FLOW-Cut brand hydroabrasive CNC machine from HARDOX 500 material containing chrome-nickel was measured from different points with the HECKERT device. So, in the article, the microhardness of the material cut at the speed of longitudinalSuz=53.4 mm/min before and after hydroabrasive processing, as well as the microhardness of thematerial cut by hydroabrasive after being polished by cooling with water on the PHOENIX 4000polishing machine with the K120 polishing wheel, and again the microhardness from 6 different pointsvalue measured on HV60.

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. Thus, the study of hardness in hydroabrasive cutting using multi-factor planning is one of the pressing issues in mechanical engineering.
