Te Mārama ki ngā Rerekētanga i waenga i ngā Wiri Whaiaro me ngā Wiri Noa

1. Ngā Momo Miro: Mīhini me te Tātari-ā-Whaiaro
E rua ngā momo miro matua o ngā tīwiri: te miro ā-ringa me te miro-ā-unoa. Ko ngā niho mīhini, e whakarāpopototia ana ko "M" i roto i te ahumahi, ka whakamahia mō te miro-ā-nati, te miro-ā-roto rānei. He tika te nuinga me te hiku papatahi, ko tā rātou mahi matua he whakau i ngā wāhanga mīhini ki te konganuku. I tētahi atu taha, ko ngā tīwiri-ā-unoa he niho tapatoru, he porowhita-haurua rānei te āhua, he āhua ripeka. E mōhiotia ana ko ngā tīwiri raka-ā-unoa, ko tā rātou hoahoa miro kua arotauhia ka taea te whakauru ngāwari ake me te kore e hiahiatia he kōhao kua keria i mua.

2. Ngā Rerekētanga o te Hoahoa o te Upoko me te Kōtaha
Ko te rerekētanga nui i waenga i ngā tīwiri tā-ake me ngā tīwiri noa kei roto i te hoahoa o te pane me te kōtaha miro. He papatahi te pane o ngā tīwiri noa, ko ngā tīwiri tā-ake he pane koi. Hei tāpiri, ka huri haere te diameter o ngā tīwiri tā-ake mai i te pito ki te tūranga diameter noa, ko ngā tīwiri noa ia ka mau tonu te diameter ōrite, he maha ngā wā he anga iti kei te pito.

Heoi anō, he mea nui te koki o te kōtaha niho. Ko te koki kōtaha niho o ngā tīwiri noa he 60°, he pai te kaha o te pupuri me te pumau. He rerekē, ko te koki kōtaha niho o ngā tīwiri-tāpiri-ake he iti iho i te 60°, e āhei ai rātou ki te whakaputa i ō rātou ake miro i a rātou e uru ana ki ngā rauemi pēnei i te rakau, te kirihou, te konganuku angiangi rānei.

3. Ngā Whakaaro mō te Whakamahinga me te Whakamahinga
Ko ngā rerekētanga i waenga i ngā tīwiri tā-ake me ngā tīwiri noa e whakatau ana i ā rāua whakamahinga me ngā whakaaro whakamahinga. Ko ngā tīwiri noa e whakamahia ana i ngā wā e tino hira ana te whakarite me te pumau, pērā i te huihui i ngā taputapu hiko ngoikore, te whakapūmau rānei i ngā wāhanga mīhini.

Ngā tīwiri-ā-ringa, i tētahi atu ringa, he mea hanga motuhake hei hanga i ō rātou ake miro honohono i te mea ka werohia ki roto i ngā rauemi ngohengohe, ka kore e hiahiatia he kōhao kua keria i mua. He nui te whakamahinga o ēnei i roto i ngā kaupapa mahi rakau, te tāpiri i ngā taputapu ki te pakitara maroke, te huihui i ngā taonga, me te tāuta i ngā rau tuanui whakarewa.

He mea nui kia mōhio koe, kāore pea ngā tīwiri-ā-ringa e pai mō ngā mahi katoa. Ina mahi ana me ngā rauemi mārō pērā i te maitai kore waikura, i ngā koranu rānei, he mea tika kia pokaia ngā kōhao kua oti te keri kia angitu ai te whakaurunga me te kore e pakaru te tīwiri, te rauemi rānei.
