[0002] Before using the gear hobbing cutter, it is necessary to inspect the integrity of its surface to avoid tough defects, thereby preventing tooth deviation and waste of material. Most existing detection methods use laser scanning and then match it with existing templates to determine whether there are defects.

[0003] However, the following problems still exist in actual use:

[0004] Most existing detection methods directly place the gear hobbing cutter on the detection table. During the laser detection process, when affected by external forces, the gear hobbing cutter will be offset, resulting in the laser having nowhere to irradiate the detection part.

As a result, during the detection process, the front and back sides of the gear hobbing cutter need to be constantly adjusted, which affects the detection effect and reduces the detection efficiency.
