Influence of the machining strategy on the resulting properties of five-axis hard-milled bevel gears

On universal milling machines, bevel gears can be produced with standard end mills. Due to the flexible process kinematics, there are fewer restrictions with regard to implementable component geometries compared to conventional gear-cutting processes. The quality requirements for bevel gears allow deviations of only a few micrometers. For this reason, small production-related deviations can lead to the exceedance of the permissible tolerances. Furthermore, surface integrity is decisive for the load-carrying capacity of gears. In this report, the influence of the process on the bevel gear quality and the properties of the near surface zone is analyzed.
