AB - The problem of cutting difficult-to-machine materials used in the aerospace  industry, aircraft industry, and automobile industry, led to the  development and application one of today's most attractive technology for  contour cutting - abrasive water jet cutting. For the efficient use of  abrasive water jet cutting, it is of great importance to analyze the impact  of process parameters on performance indicators, such as cutting quality,  productivity, and costs. But also, from the energy utilization point of  view, it is very important to analyze the impact of these parameters on the  specific cutting energy which represents the amount of energy spent on the  removal of material in the unit time. Having this in mind, this study  presents the experimental results of abrasive water jet cutting of aluminum  alloy with the aim of creating a mathematical model for estimating specific  cutting energy as an important indicator of the degree of utilization of  the available energy in the cutting process. The mathematical model of the  specific cutting energy is explicitly represented as a non-linear function  of the process parameters, obtained by the artificial neural network.
