Ngā Whakaritenga Tukanga Whakakōpiri me te Tāutanga o ngā Pūrua Pēhi-Matao

1. Ngā Whakaritenga Matua e Toru
Mahi Hiko: Ātete iti, hekenga ngaohiko iti, whakaputa wera iti.
Mahi Ā-Mīhini: He kaha kume rawaka, ka taea te tu atu i te wiri me te kukume.
Mahi Taiao: He ātete pai ki te waikura, te ātete ki ngā ru, me te ātete ki te huarere.

2. Ngā Tawhā Tukanga Matua me te Mana Whakahaere
Te Whakataurite i te Pūrua me te Waea:
Te Wāhanga Whakawhiti o te Arataki: Me tino ōrite. Whakaūtia te wāhanga whakawhiti o te waea ki te caliper vernier, ki te ine waea rānei.
Momo Arataki: Wehewehea te parahi tahanga, te parahi tine, te parahi hiriwa-whakakikoruatia, te waea konumohe, me ētahi atu. Me whai pūrua ōrite ngā rauemi rerekē.
Te whānui o waho o te ārai: Me whakarite kia uru te oko ārai pito, te oko tautoko rānei ki runga i te ārai waea.
Teitei o te Kume me te Whānui o te Kume:
Teitei o te Whakapiri: Koinei te tawhā whakahaere tino nui. I whakaratohia e te kaihanga o te pito me te awhe manawanui mārama (hei tauira, ±0.1mm). Kāore e taea te whakau tika i te teitei rawa, ā, ka whati pea ngā aho waea i te iti rawa.
Whānui o te kume: Ko te tikanga ka whakatauhia e te mata, engari me tutuki hoki ki ngā paerewa.
Me whakamahi i te "ira teitei kume" (ira Go/No-Go) mō te tirotiro tuatahi me te tirotiro ā-wā.
Ngā Mate Whakakōpiri:
Me whakamahi ngā mate motuhake e ōrite ana ki te tauira o te pūrua me te rahi o te waea.
Kāore e tino whakaaetia te whakamahi i ngā kūmau, i ngā mati rānei kāore i te ōrite mō te whakakoi.
Te Aroturuki i te Kaha Kutikuti/Te Huringa Kutikuti: I roto i te whakaputanga aunoa, ka aroturukitia te pihi nekehanga-kaha o te mīhini kutikuti kia mōhio ai he rite tonu te kounga o ia kutikuti.

3. Ngā Whakaritenga mō te Wāhi Whakapiko me te Kounga
Tomokanga Mura: Me hanga he mura ki te pito tomo waea (ko te tikanga ka whakaratohia e te mata) hei ārai i te tapahi i te waea.
Rohe Whakakōpiri o te Kaiārahi (Pēra Kaiārahi):
Me kapi katoa ngā aho katoa, kaua e ngaro, e kitea rānei ngā waea.
Me hanga te tapawhā-ono, kia rite rānei te āhua o te wāhanga whakawhiti kua whakapikohia.
Tērā pea ka paku puta ake ētahi miro (1-2 te nuinga) ki te pito, he tohu tēnei kua kī te miro.
Rohe Whakapūmau Ārai:
Ko te paparanga whakamarumaru anake me whakapiko, hei whakamama i te ahotea me te whakau ā-ringa.
Kaua e whakapiko ki te kaiārahi hiko, ā, kia tino mohio kei tino wetekina.
Me paku pupuhi te whakamarumaru, he tohu kei te mau tonu.
Ngā Wāhi Tirotiro Tirohanga:
Kāore he waea e kitea ana, e piri ana rānei ki waho.
Kāore he ngatata, he piko, he nui rawa rānei te whakarerekētanga o ngā pito.
Kāore he pakaru o te wāhi whakakoi whakamarumaru.
