Ko te tāraiwa CNC ā-ringa-whāwhāi he ratonga hangarua matatau e whai ana i ngā tikanga arataki rorohiko hei āhua tika, āhua hāngai, me te waihanga i ngā āhuatanga ki tētahi tauira nui o ngā matapae e ai ki ngā whakaritenga motuhake a te kiritaki. Kaua ko te pūpahi noa iho te roanga o tēnei ratonga, engari he nuinga hoki ngā aronga pērā i te tāraiwa tio, te tāraiwa plasma, te tāraiwa wai-tere, me te tāraiwa karu, ka whiriwhiria ia kāinga mō te matapae, te tere, te pono me te kounga mata. Ka timata te tikanga ki tētahi kōnae matihiko (hei tauira, tētahi tauira DXF, tauira CAD), ka pānuihia e te punaha CNC hei arataki i te taputapu tāraiwa ki te pono tino. He mea nui te tāraiwa CNC ā-ringa-whāwhāi mō ngā wāhanga e kore nei he tōpapa rorohiko, he rite rānei, pērā i ngā āhua 2D herenga, ngā paraka herenga, ngā kāwai whare, me ngā tohu. Ko te painga matua ko tōna maroke; ka taea e ia te whakahaere i ngā tauira kotahi, me ngā huinga iti ki te waenga kaua e hiahiatia ngā taputapu pāmahana pērā i ngā porotiti, ngā takotoranga rānei. Nō reira, he pai rawa mō te whanaketanga tere, te hanga ā-ringa-whāwhāi, me te hangarua just-in-time. Hei tauira, ko te tāraiwa wai-tere he tikanga tāraiwa makariri e taea ai te tārai i ngā metara, i te kōhatu, i te karaihe, me ngā matapae huinga kaua e hāpai i tētahi rohe pakaru mai i te wera. Ko te tāraiwa tio e tuku ana i te tere tino, me te mata tino pai ki te paparanga metara, ā, ko te plasma he iti ake te utu mō ngā matapae tere ake e taea ai te wera. Ko tētahi ratonga tāraiwa CNC ā-ringa-whāwhāi matua e tuku ana i te mātauranga mō te whiriwhiri i te tikanga tino pai, te whakauru i ngā wāhanga kia iti ai te turaki matapae, me te whakapono kia tutuki ngā herekore tino me ngā herekore ā-hākinakina, e tuku ana i ngā ratonga ā-ringa-whāwhāi mō ngā umanga mai i te motokā, te haerenga ki te rangi, te hanga whare, ki ngā hua kaihoko.
