A'oti mea fa'apipi'io se meafaigaluega tipi faʻapitoa faʻaaogaina ifa'aoga mea fa'aoga—se fa'agasologa o masini e maua mai ai ni mea fa'atosina, fa'ama'i, ma anufe. O le tipi (po'o le "hob") o lo'o i ai nifo tipi e fa'asolosolo fa'asolosolo le fa'ailoga o mea e fa'aogaina e ala i se gaio'i fa'ata'amilo fa'atasi ma le mea faigaluega.
1. Ituaiga o Mea Fa'ato'a Fa'a'oti
E ala i le Fuafuaga
| Ituaiga | Fa'amatalaga | Talosaga |
| Pusa Nifo Sa'o | O nifo e tutusa ma le axis; faiga sili ona faigofie. | Fa'ato'a maualalo mea fa'aoso. |
| Ogo Nifo Helical | Nifo i se tulimanu (pei o se anufe); sili atu le aveeseina o chip. | Meli Helical & maualuga sa'o. |
| Chamfered Hob | E aofia ai fa'alava e fa'asa'o pito o mea fa'aoga a'o tipi. | Taavale & gaosiga tele. |
| Tufuga'i | Manu'a loloto i le va o nifo mo le kilia lelei o le pu i tipi mamafa. | Lapopo'a masini fa'aoga (fa'ata'ita'iga, mining). |
E ala i Mea
HSS (Uamea Saosaoa) Hobs- Tamaoaiga, faʻaaogaina mo mea vaivai (alumi, apamemea).
Omeamea kapiti– Faigata, umi le ola, fa'aaoga mo u'amea malo & gaosiga maualuga.
Opu ua ufiufi (TiN, TiAlN)- Faʻaitiitia feteʻenaʻiga, faʻalautele le ola meafaigaluega i mea faigata.
2. Fa'aautu Autu o se Pusa
Module (M) / Diametral Pitch (DP)– Fa'amatala le tele o nifo.
Numera o Amata– Amata tasi (masani) vs. tele-amata (vave vave).
O'omiga Mata'utia (α)– E masani lava20°(masani) pe14.5°(faiga tuai).
Vaitafe i fafo– E a'afia ai le ma'a'a ma le saosaoa tipi.
Ta'ita'i Angle– E fetaui ma le tulimanu o le helix mo mea faʻaoga faʻasolosolo.
3. Fa'afefea ona galue le Gear Hobbing?
Mea faigaluega & Taamilomilo– O le ogaumu (cutter) ma le mea e fa'aoga avanoa e taamilo i le ogatasi.
Fafaga Axial– O le ogaumu e fealua'i solo i luga o le mea fa'aoga avanoa e tipi faasolosolo ai nifo.
Fa'atupu Gaioiga– O nifo o le ogaumu e fau ai le fa'ailoga sa'o.
Tulaga lelei o Hobbing
✔ Tulaga maualuga o le gaosiga (vs. fau po'o vili).
✔ Lelei mospur, helical, ma anufe.
✔ E sili atu le fa'ai'uga i luga o le pito i luga nai lo le fa'asolo.
4. Talosaga o Gear Hobs
| Alamanuia | Fa'aoga Tulaga |
| Ta'avale | Meli fa'aliliu, 'ese'esega. |
| Aerospace | Meli afi ma mea fa'agaioia. |
| Alamanuia | Pamu fa'atau, fa'aitiitiga, masini mamafa. |
| Robotics | Fa'atonuga fa'atonuga. |
5. Filifiliga & Tausiga Fautuaga
Filifili le ituaiga hob sa'o(HSS mo mea vaivai, carbide mo uamea malo).
Fa'asilisili le saosaoa tipi & fua fafaga(fa'alagolago i meafaitino & module).
Fa'aaoga le vai malulue faʻalautele ai le ola o meafaigaluega (aemaise mo carbide hobs).
Su'esu'e mo le ofuina(ta'i nifo, ofu i luga o le pito) e aloese ai mai le leaga o mea e gaosi ai.
6. Ta'ita'i Fa'amea Ta'avale Hob
Gleason(Sa'o lelei ogaumu mo ta'amilomilo pi'o & mea fa'a'ai'o)
LMT Meafaigaluega(HSS maualuga ma ogaumu carbide)
Fetu SU(Oga fa'apitoa mo fa'aoga fa'apitoa)
Nachi-Fujikoshi(Iapani, fa'aofuofu fa'aofuofu maualuga)
