The selection of tools for creating digital doubles for the development, manufacture and operation of cartridge casings of sports and hunting caliber 7.62 x 39 mm was carried out. At the development stage, the computer program calculates the technological process of the sleeve manufacturing according to a given algorithm. At the manufacturing stage, with the help of modern inspection machines, it monitors and measures the geometric parameters of the quality of the semi-finished sleeve at each technological operation. The measured values are numerically transmitted to a personal computer for analysis and processing. Data processing is carried out using the method of artificial neural networks, embedded in one of the modules of the statistical program. In the program, using previously trained INS, the predicted values of quality parameters are obtained for the subsequent operation. Based on the forecast values, if necessary, a management decision is made on the impact on the process, equipment adjustment, and tool replacement. To check the sleeve at the stage of the sleeve operation, a digital double of the sleeve was created based on the finite element method relations for the elastic-plastic reinforcing material. The digital double allows you to identify the distribution of stresses and deformations in the shell when it is loaded with pressure before conducting full-scale tests.
