Ko te pokapū mātai aksia-toru, e mōhiotia ana mā tana toru ngā aksia rārangi (X, Y, me te Z), ko te rīwhi CNC iti whanuitia rawa atu me te takotoranga taketake i te ao hangarau. Ko tana hoahoa he mea noa: ko te pūkete, e mau nei i te taputapu mata, e nuku ana ki runga ki raro (te aksia Z), waihoki ko te taonga mahi, ka tūtohua atu ki te tepu, ka nukuhia ki te papanga horizonta (ngā aksia X me Y). E tuku ana tēnei tohu i te raihana tino āhuatanga, me te whai wāhi iti ake hoki mō te nuinga o ngā mahi mātai. Ko te kaha matua o te mātai aksia-toru kei tana āwhina pai ki te mātai 2.5D—ngā mahi e amaltia ana i ngā āhua e rua dimensihana engari ka whakaputangia, whakapokai rānei ki ngā hōhonu rereke. Ko te whakauru ki ngā mata paparua, ngā rāwiti, ngā pokapoka, me te ruaruatanga, tākarotanga hoki i ngā waru. He karawhiti tino nui ia mō te hanga i te tauira nui o ngā wae, mai i ngā whatitata, ngā pepere ki ngā mōhini, ngā pāpā hoki anuanu, kia taea ai te uru atu ki ngā āhuatanga matua katoa mai i tētahi tārā e rite ana ki te aksia Z. Ka kitea te here o te mātai aksia-toru ina mātai ana i ngā wae e whai anuanu ana, e maha ngā taha, tāraiwa rānei. Hei tauira, hei mātai i ngā rima taha o te porowhita, me whakarerekē anō te wae kotahi, minore rānei, e āwhina ana i te aronga o te wehenga, me te hui haerenga o ngā whārite. Ahakoa tēnā, ko tana noa, tana whakapono, me tana utu iti ake ka whakamahia ai ia hei kōwhiringa pai mō ngā toihanga mahi, ngā wāhi tirotiro, me te hanga kaha i ngā wae e kore e hiahiatia ai te āhua mātai aksia-maha atu i te wā kotahi. Ko ngā pokapū mātai aksia-toru hou hauanui e whai ake ana i ngā kaiwhakarerekē taputapu tūmatohia, ngā pūnaha rapu, me ngā pūkete tere-tere, ka nui ake te hua o ēnei i roto i ō rātou rohe. Waihoki, ko rātou te takotoranga matua o te maha o ngā mahi hangarau, me te mātauranga whānui i ō rātou kaha, me ō rātou here, ko te tuatahi o ngā huarahi hei kōwhiri i te hangarau CNC tika mō ia tono mātai.
