摘要

The bevel gear normal (10) has a calibration reference surface (12), which is designed such that a coordinate system of bevel gear normal is determined. Two geometric elements (14.1,14.2,14.3) are configured in the form of spheres or sphere portions. The geometric elements are arranged in equidistant angle steps. An independent claim is also included for a method for monitoring or correcting a bevel gear-measurement process.
