Methodology for Design and Research of Vibration Stability of Cylindrical Milling Cutters with Nonuniform Tooth Inclination Angle

The calculation and construction of a structural scheme of a cylindrical milling cutter with different pitch and nonuniform angle of inclination of teeth, with increased vibration resistance, are considered. The dependence of the forced oscillation frequency of the milling cutter on the milling modes, pitch, and inclination angle of the teeth is obtained, which makes it possible to study the vibration resistance of the milling cutter in comparison with a nonuniform pitch milling cutter with a constant inclination angle of the teeth. The “resistance” of the studied cutter to resonances arising during milling is shown.
