Ka whakaratohia e tēnei tuhinga he tirohanga taipitopito mō ngā mātāpono mahi, ngā painga hangarau, me ngā whakamahinga motuhake o ngā mīhini kukume waea 12-mate i roto i te hanga mekameka.

1. Hanganga Taketake me te Mātāpono Mahi o te Mīhini Tuhi Waea 12-Mata

（1）Hanganga Mīhini

Ko te mīhini tuhi waea 12-mate he taputapu tukatuka waea maha-wāhanga e titoa ana i ngā wāhanga matua e whai ake nei:

Tūnga Wetewete: Ka pupuri i te waea whakarewa mata (hei tauira, te koura, te hiriwa, te parahi).

Huinga Mate Tuhi Waea: Kei roto i tēnei kete ngā mate e 12 me ngā kōhao iti haere hei whakaiti haere i te whānui o te waea.

Pūnaha Whakahaere Kume: Ka whakarite kia ōrite te tohatoha o te kaha i te wā e kume ana hei ārai i te whati, i te whakarerekētanga rānei.

Wāhanga Whakahoki: Ka takai marie i te waea kua oti mō te tukatuka i muri mai.

（2） Te Mātāpono Mahi

Ka whakamahia e te mīhini kume waea 12-mati he tukanga kume haere tonu. Ka haere te waea whakarewa i roto i ngā mati 12 e whakaiti ana i te rahi, ka whakaiti haere i te diameter i raro i te kaha kume kia tae rā anō ki te matotoru e hiahiatia ana. Mā tēnei tikanga ka tino whai hua, ka pumau hoki, ā, he pai mō te hanga papatipu.

2. Ngā Painga o ngā Mīhini Tuhi Waea 12-Mata i roto i te Hanganga Tahei

（1）Whakapai ake i te Whai Hua o te Whakaputa

He rerekē tēnei i ngā mīhini mati kotahi e hiahia ana kia whakawhiti mati pinepine, ka oti i te mīhini mati 12 ngā wāhanga tuhi maha i te kotahi haerenga, ā, ka tino whakaitihia te wā tukatuka me te whakapai ake i te pai o te whakaputanga whānui.

（2）Te Kounga Waea Tino Pai

Mā te tukanga tuhi maha-wāhanga ka whakaitihia te ahotea o roto o te whakarewa, ka ārai i ngā kapiti mata, i ngā kopa rānei, ā, ka whakapai ake i te pakari me te whakaotinga o ngā hei.

（3）Te Hototahi ki ngā Mea Whakarewa Rerekē

Ka tautoko te mīhini i te kukume i ngā konganuku utu nui pērā i te koura, te hiriwa, te parahi, me te konukawata, hei whakatutuki i ngā hiahia rauemi rerekē mō te whakakai.

（4）Te Whai Hua o te Pūngao

Ki te whakatauritea ki ngā mīhini mati-kotahi, ka whakaitihia e te pūnaha mati-12 ngā huringa tīmatanga-mutu, ka whakaitihia te whakapaunga pūngao, ā, ka hangai ki ngā tikanga hanga pumau o ēnei rā.

3. Ngā Whakamahinga i roto i ngā Raina Hanga Heihei

（1） Te Hanga Hononga Mekameka Pai

He maha ngā wā ka hiahiatia he waea tino angiangi mō ngā mekameka whakakai hei whatu. Ka taea e te mīhini 12-mata te hanga waea kia rite ki te 0.1mm te matotoru, kia maeneene, kia ngāwari hoki ngā hononga mekameka.

（2）Tautoko mō ngā Hoahoa Ritenga

Mā te whakarerekē i ngā whirihoranga o te mate, ka hangaia e te mīhini ngā waea o ngā diameter rerekē, kia tutuki ai ngā hiahia o ngā kaihoahoa mō te matotoru me te ngāwari kua whakaritea.

（3） Te Whakaurunga ki ngā Taputapu o te Raro

Ka taea te whāngai tika i ngā waea kua kumea ki roto i ngā mīhini miro, i ngā mīhini whiri, i ētahi atu taputapu rānei, ka hanga he raina whakaputa aunoa maeneene.

4. Ngā Auahatanga Whanaketanga ā-Mārama

I te mea e hiahiatia ana te tika me te whai huatanga nui ake mō te hanga whakapaipai, kei te whanake haere ngā mīhini kume waea 12-mate ki ngā otinga atamai ake, aunoa ake hoki, pēnei i:

Ngā Pūnaha Whakahaere Maamaa: Te aroturuki i te wā-tūturu mā roto i ngā pūoko hei whakarerekē aunoa i ngā tawhā.

Ngā Mate Tino Tika: Hangarau paninga-nano hei whakaroa i te roa o te ora o te mate me te whakapai ake i te tika.

Te Whakaurunga ki te Tānga 3-A: Te whakahohe i ngā whakaritenga ngāwari ake i roto i te hanga hei.

Whakamutunga

Ko te mīhini kukume waea 12-mati, me tōna pai, tōna pumau, me tōna whānui, kua noho hei wāhanga nui o ngā raina hanga hei. Ehara i te mea ka whakanui ake i te hua me te kounga o te hua anake, engari ka whakatuwherahia hoki ngā huarahi hou mō ngā hoahoa motuhake. Mā te haere tonu o ngā whanaketanga hangarau, ka haere tonu tēnei mīhini ki te akiaki i te umanga whakapaipai ki ngā paerewa hiranga teitei ake.
