Three core gear cutting methods compared
| Method | Accuracy | Module Range | Production Speed | Tool Cost |
|---|---|---|---|---|
| Hobbing | DIN 5-7 | 0.5-40mm | Fastest | Medium |
| Shaping | DIN 6-8 | 0.5-12mm | Medium | Low |
| Grinding | DIN 3-5 | 1-20mm | Slowest | High |
Hobbing: most economical for external spur/helical gears. Shaping: internal gears, cluster gears. Grinding: hardened gears requiring highest precision (automotive transmission).
