Simulation‑based design of flank face modification for the milling of Ti‑6Al‑4V and Inconel 718

The milling of titanium and nickel-based alloys leads to high tool wear due to the high thermomechanical load on the tool. By modifying the fank face on end mills, it is possible to limit the increase in the width of fank wear land, thus increasing tool life, component quality and increasing the allowable productivity of the tools. The fank face modifcation is characterized by the width and depth of the undercut and the rounding in the undercut of the modifcation. Through a simulation-based approach, a method is created to design the fank face modifcation in a load-optimized way and thus to use the full potential in the respective application cases.
