In machining high steel 2.25Cr-1Mo-0.25V, cutting force is large, and tool is prone to adhesion failure. In order to study the distribution of force density function and stress state on the rake face of H-slot blade. Experiments were carried out to study the contact phenomenon in tool rake face. Based on it, the force density function was established and it was showed through 3d view. The force distribution law was analyzed. The force density function was used as the boundary conditions. Tool stress field was simulated using FEM. The simulation results are in good agreement with the theoretical analysis results. The investigative results provide a theoretical foundation for solving the key technical problems of tool breakage in the automated production, and for studying optimization technology of groove.
