This study explores the optimization of interpolation techniques for thermomechanical coefficients in non-ferrous metals and high-alloy steels. These coefficients, including the temperature coefficient (Kt), deformation degree coefficient (Kε), and deformation rate coefficient (Ku), play a crucial role in characterizing the deformation resistance of materials under varying conditions. The challenge lies in the non-linear nature of these coefficients and their current representation in graphs and tables, which hinders their integration into automated control and optimization systems. To address this issue, we propose the development of smooth interpolation functions using the least squares method. Our research aims to identify the most precise interpolation approach for a wide range of non-ferrous metals and high-alloy steels, facilitating more accurate mathematical modeling of their thermomechanical properties. This advancement will enable improved prediction and control of material behavior in complex manufacturing processes, ultimately enhancing the efficiency and precision of metal forming operations
