Q: he aha'He aha te rerekētanga i waenga i te whakawhānui ngongo whakaitiiti me te whakawhānui ngongo kore whakaitiiti?

A: 

Ko te rerekētanga i waenganui i tewhakamīharo te whakawhānui o te ngongo me tekore e mimiti He mea nui ngā tukanga whakawhānui ngongo i roto i ngā whakawhiti wera, e ai ki ngā mātāpono me ngā tono.

Smimiti te whakawhānui o te ngongo

Tewhakamīharo He tikanga hanga miihini noa te tukanga whakawhanui ngongo. I te wā e whakawhanui ana te ngongo, ka piki ake te diameter o te ngongo parahi nā te rahi nui o te pōro whakawhanui ki te diameter o roto o te ngongo, ka hua ake he hononga piri ki ngā tara, ā, ka pai ake te pai o te whakawhiti wera o te whakawhiti wera. Heoi, ka hua ake i tēnei momo whakawhanui ngongo te pikinga o te horahanga whakawhiti o te ngongo parahi, ka heke te roa o te ngongo, e mōhiotia ana ko te tere whakaheke o te ngongo parahi. Hei tauira, i roto i te umanga hauhautanga, ko te tere whakaheke o ngā ngongo parahi miro-roto he 3%-4%.

Skore e mimiti te whakawhānui o te ngongo

The kore e mimiti Ko te tukanga whakawhanui ngongo he tikanga whakawhanui ngongo ā-kaha. Ka whakatikatika i te pikinga o te diameter o roto o te ngongo parahi mā te whakanui ake i te matotoru o te pakitara, kia kore ai e mimiti te roa o te ngongo parahi i muri i te whakawhanui ngongo. Me whakamahi he taputapu motuhake i runga i te mīhini whakawhanui ngongo hei whakapiri i ngā pito o te ngongo, ā,He titi makawe-ngā raro o ngā ngongo o ngā wāhanga whakawhiti wera i mua i te whakawhanuitanga o te ngongo. I murikore e mimiti te whānui o te ngongo, ka puta ngā panoni ki te diameter o roto me ngā tawhā miro o te ngongo parahi, e hiahiatia ana te whakamana i te mahi whakawhiti wera, te pēhanga pūnaha, me te mahi roa o te whakawhiti wera. Hei tāpiri, ko ētahi hoahoa okore e mimiti Ko te whakawhānui ngongo kei roto ko ngā rara o roto e whakamahi ana i te kaha kume ki te tinana ngongo i te wā e whakawhānui ana, hei aukati i te mimiti o te ngongo, me te whakarite kia rite te whakawhānui o te ngongo hei whakapai ake i te kawe wera.

Hei whakarāpopototanga, ko te rerekētanga matua i waenga iwhakamīharo mekore e mimiti Ko ngā tukanga whakawhānui ngongo kei roto i te whakaiti i te kaha o te ngongo parahi i muri i te whakawhānui, me te āhua o te hoahoa o te tukanga e taea ai te whakapai ake i te mahi a te whakawhiti wera. Ko te whiriwhiringa motuhake o te tukanga ka whakawhirinaki ki ngā whakaritenga tono motuhake me ngā āhuatanga o te tukanga.
