Statement of the problem and purpose of the work. The technology of machining hard-to-machine materials, which undoubtedly include high-alloy steels and chromium and nickel-based alloys, has some advantages over traditional abrasive machining methods. Among the most significant advantages, researchers note greater flexibility, faster changeover to other types of parts, the ability to combine several operations into one due to the versatility of the forming motion of the blade tool compared to the abrasive, higher productivity, and relatively low technological cost. The purpose of this publication is to present the results of studies on the influence of technological factors and cutting tool geometry on the machinability of chromium-nickel steels and alloys. Methods. For numerical analysis and comparison with analytical and experimental results, the Deform 2D V.11/02 software package was used in this study. The Newton-Raphson method was used as an iterative research method. The incremental Lagrange model considered the type of deformation process in the cutting simulation model. The main computational core of the simulation model was an algorithm based on the sparse matrix technique. Results of the article. Based on the results of the analysis of the above studies, the dynamics of the power, stress-strain, and thermodynamic state of the tool were evaluated, taking into account the specified cutting parameters and changes in the geometry of the cutting blade during the machining of chromium-nickel alloy IN 718. Scientific novelty. The paper presents an analysis of the influence of the cutting blade geometry and, in particular, the radius at the top of the tool wedge on the formation of force, stress-strain, and thermodynamic parameters of the material in the forming zone during the machining of a chromium-nickel alloy. Practical significance of the results. The developed methodology will allow for optimizing the machining modes by considering the parameters obtained from simulation modeling. Directions for further research on the subject of the article. Further research can be directed to developing a comprehensive methodology for structural and parametric optimization of technological processes for machining hard-to-machine materials based on chromium, nickel, vanadium, molybdenum, and other alloying materials of steels and alloys.
