Optimization of cutting modes when drilling hardened steel based on Abaqus/Explicit modeling
Incoming article date: 04.06.2025Drilling of hardened steel 40 HRC 24...32 is investigated using numerical simulation in Abaqus/Explicit. The stress-strain state is analyzed. It has been found that optimization of cutting modes (feed speeds and revolutions) reduces Mises stresses to 55% of the ultimate strength, increasing tool durability. The results show the dependence of stress distribution on cutting parameters and the influence of drill geometry on the machining process.
