1. Kōwhiria kia rite ki te rohe manawanui o te tap
Kua tohua ngā taputapu mīhini ā-whare ki te waehere o te rohe manawanui o te diameter pitch: ko H1, H2, me H3 e tohu ana i ngā tūranga rerekē o te rohe manawanui, engari he rite tonu te uara manawanui. Ko te waehere rohe manawanui o ngā taputapu ringaringa ko H4, ko te uara manawanui, te pitch me te hapa koki he nui ake i ngā taputapu mīhini, ā, ko te rauemi, te maimoatanga wera me te tukanga whakaputa kāore i te pai ki ngā taputapu mīhini.
Kāore pea te H4 e tohua kia rite ki te mea e hiahiatia ana. Ko ngā tohu rohe ātete miro ā-roto ka taea te tukatuka e te rohe ātete piko tap koia ēnei: Ka pā te waehere rohe ātete tap ki ngā tohu rohe ātete miro ā-roto H1 4H, 5H; H2 5G, 6H; H3 6G, 7H, 7G; H4 6H, 7H. Ka whakamahia e ētahi kamupene ngā tap kawemai. He maha ngā wā ka tohua ngā tap e ngā kaihanga Tiamana ko ISO1 4H; ISO2 6H; ISO3 6G (he rite te paerewa o te ao ISO1-3 ki te paerewa ā-motu H1-3), kia tohua ai te waehere rohe ātete tap me te rohe ātete miro ā-roto ka taea te tukatuka.
Te whiriwhiri i te paerewa o te miro E toru ngā paerewa whānui mō ngā miro noa i tēnei wā: te metric, te imperial, me te unified (e mōhiotia ana ko te American). Ko te pūnaha metric he miro me te koki niho o te 60 nekehanga i roto i te mirimita.
2. Kōwhiria kia rite ki te momo tap
Ko ngā mea e whakamahia pinepinetia ana e mātou ko: ngā taputapu putorino tika, ngā taputapu putorino porowhita, ngā taputapu ira porowhita, ngā taputapu whakaputa, he painga anō tō ia taputapu.
Ko ngā taputapu pūtorino tika te mea tino kaha ki te whakamahi, ka taea te tukatuka i te mea mā roto i te kōhao, te mea kore rānei e mā roto i te kōhao, te mea kore-whakarewa, te mea whakarewa rānei, ā, ko te utu te mea iti rawa. Heoi, he iti hoki te hiranga, ka taea te mahi i ngā mea katoa, kāore he mea pai rawa atu. Ka taea e te wāhanga kōne tapahi te whai niho e 2, e 4, me te 6. Ka whakamahia te kōne poto mō ngā kōhao kore-mā roto, ā, ka whakamahia te kōne roa mō ngā kōhao mā roto. Mena he hohonu te kōhao o raro, me roa te kōne tapahi kia rite ki te taea, kia maha ake ai ngā niho e tohatoha ana i te kawenga tapahi, kia roa ake ai te ora mahi.
He pai ake ngā taputapu pūwero porowhita mō te tukatuka i ngā miro kore-pū, ā, ka tukuna whakamuri ngā maramara i te wā e tukatuka ana. Nā te koki porowhita, ka piki ake te koki tapahi tuturu o te taputapu i te pikinga ake o te koki porowhita. E whakaatu ana ngā wheako: Mō te tukatuka i ngā konganuku rino, me iti ake te koki porowhita, tata ki te 30 nekehanga, kia mau ai te kaha o ngā niho porowhita. Mō te tukatuka i ngā konganuku kore-rino, me nui ake te koki porowhita, tata ki te 45 nekehanga, ā, me koi ake te tapahi.
Ka tukuna te maramara ki mua ina tukatukahia te miro e te pūwāhi. He nui te hoahoa o tōna matua, he pai ake te kaha, ā, ka taea te tu atu i ngā kaha tapahi nui ake. He tino pai te pānga o te tukatuka i ngā konganuku kore-ferrous, te maitai kore-waikura, me ngā konganuku ferrous, ā, me whakamahi pai ngā pūwāhi tīwiri mō ngā miro puta-kōhao.
He pai ake ngā taputapu whakaputa mō te tukatuka i ngā konganuku kore-ferrous. He rerekē i te kaupapa mahi o ngā taputapu tapahi i runga ake nei, ka whakaputahia te konganuku kia rerekē ai te āhua, kia puta ai he miro o roto. He tonu te muka konganuku o roto kua whakaputahia, he kaha te kume me te kutikuti, ā, he pai te taratara o te mata. Heoi, he nui ake ngā whakaritenga mō te kōhao o raro o te taputapu whakaputa: he nui rawa, ā, he iti te nui o te konganuku turanga, ka hua ake he nui rawa te diameter o roto o te miro, ā, kāore e ranea te kaha. Ki te iti rawa, kāore he wāhi e haere ai te konganuku kua kati me te kua whakaputahia, ka pakaru te taputapu.
