Ko te pōro maitai whāriki he pōro maitai ahumahi noa e whakamahia ana mō ngā wāhanga nekeneke o ngā whāriki me ētahi atu taputapu miihini. He kaha teitei, he pakeke, he ātete ki te kakahu, nō reira he mea tino nui te whakahaere i runga i te tukanga me te pānga. Ka whakamāramahia i raro nei te tukanga maimoatanga wera me te pānga o ngā pōro maitai whāriki.
Ko te maimoatanga wera e pā ana ki tētahi raupapa o ngā tukanga hangarau mā te whakamahana me te whakamatao i ngā rauemi hei whakarerekē i te hanganga whakahaere me ngā āhuatanga o ngā rauemi. Ko te tukanga maimoatanga wera o ngā pōro maitai e mau ana i ngā mea e whai ake nei ko te whakamahana, te tinei me te whakakākahu.
Ko te whakamahana i te pōro maitai e tineia ana he tukanga whakamahana i te pōro maitai e tineia ana ki tētahi pāmahana kua whakaritea, kātahi ka whakamatao i te wā e tika ana. Ko te kaupapa o te whakamahana he whakakore i te ahotea o roto e puta ana i te wā whakamahana, te whakaiti i te pakarukaru, me te whakapai ake i te pakari me te ngāwari. Ko te pāmahana me te wā whakamahana ka whakatauhia i runga i te hanganga me ngā whakaritenga motuhake o te pōro maitai e tineia ana. Ki te iti rawa te pāmahana whakamahana, ki te poto rawa rānei te wā, ka piki ake te ahotea toenga, ki te kore e ranea te whakamahana, ka pā ki te mahi a te pōro maitai e tineia ana; ki te teitei rawa te pāmahana whakamahana, ki te roa rawa rānei te wā, ka whakaiti i te pakeke me te ātete ki te kakahu. Nō reira, he mea tino nui te whakahaere i te tukanga whakamahana.
Tuarua, ko te tinei te tukanga whakamahana matua o te pōro maitai e mau ana, mā te whakamahana i te pōro maitai e mau ana ki te pāmahana tino nui, kātahi ka tere te whakamatao, kia rite ki te martensite, ki te bainite rānei. Ka taea e te tinei te whakapai ake i te pakeke me te kaha o te pōro maitai e mau ana, te whakanui ake i tōna ātete kakahu me te roa o te mahi. Ko te reo whakamatao i roto i te tukanga tinei he hinu, he wai, he hau rānei, ā, ko te reo whakamatao e tika ana ka tīpakohia kia rite ki ngā whakaritenga motuhake o te pōro maitai e mau ana. Ko te pāmahana tinei, te tere whakamatao me te kōwhiringa o te reo whakamatao ka pā nui ki te hanganga me te mahi o te pōro maitai e mau ana. Ki te tino teitei te pāmahana, ki te tere whakamatao tere rawa rānei, ka pakaru, ka rerekē te āhua; ki te tino iti te pāmahana, ki te tino puhoi rānei te tere whakamatao, ka pā ki te pakeke me te kaha.
He tukanga whakapakari mata noa te whakakākahu i te waro, mā te tuku i te pōro maitai whāriki ki roto i tētahi matū kei roto ngā huānga waro hei whakamahana, kia uru ai ngā huānga waro ki te mata o te pōro maitai, kia nui ake ai tōna pakeke me te ātete ki te kakahu. He pānga nui te pāmahana, te wā o te tukanga whakakākahu me te whiriwhiri i te reo whakakākahu ki te matotoru me te pakeke o te paparanga whakakākahu. Ka taea e te pāmahana teitei rawa, te wā roa rawa rānei te arahi ki te mimiti, ka pā te pāmahana iti rawa, te wā poto rawa rānei ki te kounga me te pānga o te paparanga whakakākahu.
Ko te pānga maimoatanga wera o ngā pōro maitai e mau ana i te nuinga o te wā ka aromatawaihia e ētahi tohu mahi, pērā i te pakeke, te ātete kakahu, te pakari me ētahi atu. Ko te pānga maimoatanga wera tino pai me pakeke taurite, he ātete kakahu pai, me te whakaaro ki te pakari hei whakarite i te roa me te pono o te pōro maitai e mau ana i te wā e whakamahia ana.
Ko te arotau me te whakahaere i ngā tukanga me ngā pānga o te maimoatanga wera me whai taputapu me te hangarau matatau, me ngā kaiwhakahaere mohio hoki. I roto i te mahi whakaputa tūturu, me whakarerekē me te arotau hoki kia rite ki ngā whakaritenga rauemi me ngā tukanga motuhake kia tutuki ai te kounga me te mahi o ngā pōro maitai whāriki i ngā paerewa me ngā whakaritenga a te kiritaki.
