Ko ngā mōhini tūtohu matotoru e mōhiotia ana hei ngā taputapu rereke, āhua hahau hahau e hangaia ana i mua i te wā o te whakaputa haumaru i te pāpaku inihini. Ko te kounga, te hoahoa, me te hanganga o ēnei mōhini te take tino nui rawa atu ki te whakatau i te angitu, te maroke, me te utu-āhua o te mahi katoa. Ko te hanganga i tētahi mōhini tūtohu matotoru he kaupapa matatau e hono ana i te hoahoa matatau, ngā matapae kounga teitei, me te mātauranga tōmuri. Ka tīmata ia ki ngā pūnaha CAD/CAE matatau mō te hoahoa me te whakamimiti rere, kia āwhina ai i ngā mātai hoahoa kia whanaketia te mōhini mō te taurite kōpae, te maroke maroke, me te wehenga wae, ka taea ai te whakarāpopoto me te aukati i ngā hapa e taea ana. Ko te turanga mōhini me ngā karu e hangaia ana i ngā paraihe toa tikangia, paraihe kua pakaruia, i ngā paraihe mōhini (pērā i te paraihe miriro 420, i te paraihe taputapu H13) kia taea ai te herekenga ki te āhua pākiuru, ki te āhua pāpaku o ngā pāpaku inihini, me ngā pēhi maha o te inihini. Ko te prosihia mātai e whakamahi ana i te CNC tere tere, EDM (Electrical Discharge Machining) mō ngā taipitopito heruheru, me te whakapau kia eke ki ngā roa micron me ngā mata motuhake ki ngā pātu karu. Ko ngā wae taputapu pērā i ngā pini wehe, ngā pini arataki, me ngā pūtau e whiriwhiria ana mai i ngā matapae kia taea te pānga, ā, e hangaia ana ki ngā paerewa tino tikangia kia whakarite kia pai, roa hoki te wā o te mahi. Ko ngā ara maroke e hoahoa ana, e mātai ana kia tuku i te wera kotahi, tere hoki, he mea nui tēnā ki te whakahaere i ngā wā mātai, ki te iti iho i te wehenga wae. Anō, ko ngā mōhini tūtohu matotoru e uru ana ki ngā āhuatanga heruheru pērā i ngā porowhata, ngā kōpae, me ngā tikanga whakangao kia waihangahia ngā wae me ngā āhuatanga takotoranga, āhuatanga heruheru. Ko te whakapumautanga mutunga he tāpoi, kei reira ka waihangaia ngā wae tuatahi, ka nekehia, ka tātaritia kia whanake ake te mōhini me ngā paramita inihini. Ko te uara i tētahi mōhini tūtohu matotoru pai i te kaihanga whaimana he whakataunga ā-strujia e utua ana trātata ana te iti ake i te wā kore mahi, te kounga ōrite o ngā wae i runga i ngā tau tekau mano, me te iti ake i te utu katoa o te whai.
