Ko te whakauru rorohiko mātai CNC te tikanga matua, matapōkere hoki i te huri i te tauira CAD toru-āhuā o tētahi wae tapa ki tētahi takotoranga tohu pono, āhuatia, me te haumaru—e mōhiotia ana hei waehere-G—ka taea e te pokapū mātai CNC te whakatinana ai. Kei te wāhi e huinga ana te mataara rorohiko, te tātaritanga mātai, me te mōhio wharemahana arataki tēnei kaupapa. Ko te tikanga e mahia ana hauoraia mā te whakamahi i te rorohiko Whakarato Rorohiko-a-Kaitiaki (CAM), e āwhina ai i te kaiwhakauru ki te hanga i tētahi kape matihiko o te tikanga mātai. Ka timata te rerekētanga ki te kawemai i te tauira CAD me te whakatau i te pūtau noa. Ngā wherenga ka whiriwhiria e te kaiwhakauru i ngā mahi ētahi, ko ia tetahi e hāngai ana ki te tango i tētahi rahi tuarangi o te matū. Ko te whiriwhiri i ngā taputapu tohua tika (ngā karu tohua, ngā karu whakaputa, ngā karu tap), te whakatau i ō rātou ara (hei tauira, te āhua, te pōkeno, te mata), me te whakaputanga i ngā utu tohua matua: te tere pūkaha (RPM), te tere kawe (IPM), me te tere tohua. Hei painga mō te āhuatanga me te kounga o nāianei, he mea nui ngā tikanga whakauru matatau. Hei tauira, ko ngā aronga Mātai Rawa Ake (HEM) e whakamahi ana i ngā ara karu trokoidi, rānei ārai mōhio kia mau tonu te kāwae tohua, e āwhina ana kia tere ake te kawe, me ngā tohua tino pūpono me ngā tohua āhuatia iti ake, ka iti ake te wera, ka roa ake te ora o te taputapu. Mō ngā āhua 3D, me hangaia e te kaiwhakauru ngā ara karu māmā, rerehua anuanu hoki kia kaua ai ngā huri āhuatia kītoitoi e ārai ai i ngā tohu karu me te riri. He mea matua nui hoki, me whakauru te kaupapa i ngā wherenga kore-tohua: te whakarite i ngā take roa me te tawhiti karu, te whakahaere i te rere o te makukū, te whakahau i ngā panonitanga karu aunoa, me te whakapono i ngā nuinga atamira kia kaua ai te patu ki te takotoranga, ki te wae tapa rānei. I mua i te tuku i te waehere ki te taputapu, ka whakamātauria tino āhuatia mā te whakangāhau rorohiko e whakaatu ana i te tikanga mātai katoa, e kite ana i ngā hapa i te aronga, i ngā pānga rānei e taea ana. Ko te huringa whakamutunga ko te "tāwhai-papatono", kei reira ka hurihia te raraunga ara karu māmatua o te rorohiko CAM ki te reo waehere-G motuhake e hiahiatia ana e te rorohiko CNC o te taputapu. Ehara i te takotoranga noa o ngā wherenga tētahi kaupapa mātai CNC pai—engari he poukai whai hua e whakapono ana i te pono āhuahanga, te āhua mataaho ake, te wātiha iti ake, me te ora roa rawa o te taputapu.
