The grinding parameters of spiral bevel gear arranged by single factor test are shown in the table.
| Parameters | Value |
| Grinding wheel grain size | 46 |
| Grinding speed vs (M / s) | 15.2, 17.8, 20.3, 22.8, 25.3 |
| Grinding depth AP（μm) | 10, 30, 50, 70, 90 |
| Gear generating speed w (° / s) | 6, 8, 10, 12, 14 |
| Grinding mode | Big end to small end |
| Cooling mode | Wet grinding |
In the process of machining, each tooth slot corresponds to a set of parameters. After the grinding of spiral bevel gear is completed, the tooth sample is cut inward about 10 mm deep along the big end of the gear by wire cutting, as shown in the figure. After that, clean the tooth sample in the ultrasonic cleaning machine, then observe the grinding surface morphology of the tooth surface with Kearns VK100, and measure the surface roughness with a white light interferometer.
