The implementation of the development of a software solution for calculating the milling parameters of thin-walled elements of turbomachines is presented. The production of thin-walled elements requires high attention to the choice of optimal processing parameters. Complex geometry of thin-walled elements, low ability to resist deformation with an obstacle in the process of forming high-precision surfaces. The existing solutions mainly provide for obtaining parameters for processing the surfaces of parts with absolute rigidity, so the purpose of this implementation is to take into account the features of thin – walled elements, and implement interaction with the digital representation of the physical process in a complex form. The intelligent system provides both analytical microservices for calculating and optimizing parameters, and the use of a third-party CAE environment with the ability to execute scripts. The source of the theoretical database of tabular values is publications, research, engineering machine-building reference books. Information about input parameters is structured in blocks that correspond to the element geometry, material properties, machine type and power, features of the geometry and Tool material, the process of removing allowances with the inclusion of high-speed processing mode. The implementation makes it possible to calculate the cutting forces that occur during the removal of the allowance, in the direction of the minimum rigidity of the thin-walled element. The eigenfrequencies of the loaded geometry are modeled, and the corresponding amplitude response is constructed, which is included in the analysis and a recommendation conclusion is formed for compliance with the input technical conditions. It provides for the possibility of using and accumulating research results. The aim of the research is to develop a system that can be integrated into modern production, which corresponds to the vision of the progressive concept of Industry 4.0.
