I tēnei ao hanga tino tika, ko te tino tika tonu te mea nui. Ahakoa he mīhini ine taunga (CMM), he tūāpapa taiwhanga whatu, he taputapu tuhi haurua-ira rānei, he tūāpapa toka nui te tūāpapa karāhe, ā, ko tōna papatahi te mea e whakatau tika ana i ngā rohe ine o te pūnaha.
He tokomaha te hunga e whakaaro ana i tēnei wā o te aunoatanga matatau, me mahi te mīhini papa granite mā ngā taputapu mīhini CNC aunoa katoa. Heoi, he mea miharo te āhua: kia tutuki ai te tika whakamutunga i te taumata micron, i te taumata submicron rānei, ko te taahiraa whakamutunga kei te whakawhirinaki tonu ki te huri ā-ringa a ngā tohunga mahi toi. Ehara tēnei i te tohu o te hokinga whakamuri o te hangarau, engari he whakakotahitanga hohonu o te pūtaiao, te wheako, me te mahi toi.
Ko te uara o te huri ā-ringa kei roto i ōna āheinga whakatikatika hihiri. Ko te miihini CNC he "tārua tūmau" i runga i te tika o te taputapu mīhini, ā, kāore e taea te whakatika tonu i ngā hapa iti e puta ana i te wā miihini. Ko te huri ā-ringa, i tētahi atu ringa, he mahi porowhita kati, e hiahia ana ngā kaimahi ki te tirotiro tonu i te mata ma te whakamahi i ngā taputapu pēnei i ngā taumata hiko, ngā autocollimator, me ngā interferometer laser, kātahi ka mahi i ngā whakatikatika mata ā-rohe i runga i ngā raraunga. He maha ngā wā e hiahiatia ana mō tēnei tukanga he mano ngā inenga me ngā huringa whakakanapa i mua i te whakatikatika haere o te mata o te papaaho katoa ki tētahi taumata papatahi tino teitei.
Tuarua, he mea nui te huri ā-ringa hei whakahaere i ngā taumahatanga o roto o te karāhe. He rauemi taiao te karāhe, he uaua te tohatoha taumahatanga o roto. Ka taea e te tapahi ā-ringa te whakararuraru i tēnei taurite i roto i te wā poto, ka hua ake he iti noa te whakarerekētanga i muri mai. Heoi, ko te huri ā-ringa he iti te pēhanga me te iti o te wera. I muri i te huri, ka tukuna e te tohunga te mahi kia okioki, kia tukuna noa ai ngā taumahatanga o roto o te rauemi i mua i te haere tonu me ngā whakatikatika. Mā tēnei huarahi "pōturi me te pumau" ka mau tonu te tika o te papaaho mō te whakamahinga roa.
Hei tāpiri atu, ka taea e te huri ā-ringa te hanga i ngā āhuatanga mata isotropic. He maha ngā tohu miihini ā-ringa e ahu whakamua ana, ka hua ake he rerekētanga o te waku me te auautanga i ngā ahunga rerekē. Mā te huri ā-ringa, mā te tikanga ngāwari a te tohunga mahi toi, ka hangaia he tohatoha matapōkere me te ōrite o ngā tohu kakahu, ka hua ake he kounga mata rite tonu i ngā ahunga katoa. He mea nui tēnei mō ngā pūnaha ine me te nekehanga tino tika.
He mea nui ake, he maha ngā momo kohuke o te karāneti, pērā i te quartz, te feldspar, me te mika, he rerekē te pakeke o ia kohuke. He maha ngā wā ka hua ake i te huri ā-ringa te tapahi nui rawa o ngā kohuke ngohengohe me te puta o ngā kohuke mārō, ka puta he āhua kore taurite. Ko te huri ā-ringa, i tētahi atu taha, e whakawhirinaki ana ki te wheako me te kare ā-ringa o te tohunga. Ka taea e rātou te whakarerekē tonu i te kaha me te koki i te wā o te huri, ka whakanui ake i te taurite i waenga i ngā rerekētanga o ngā kohuke, ā, ka tutuki he mata mahi ōrite ake, ātete hoki ki te kakahu.
I tētahi tikanga, ko te tukatuka i ngā papa granite tino tika he whakakotahitanga o te hangarau ine tika hou me te mahi toi tuku iho. Ka whakaratohia e ngā mīhini CNC te whai huatanga me te āhua taketake, engari me whakatutuki ā-ringa te papatahi, te pumau, me te ōritetanga tino pai. Nō reira, ko ia papa granite tino pai e whakaatu ana i te whakaaro nui me te manawanui o ngā kaimahi toi tangata.
Mō ngā kaiwhakamahi e whai ana i te tino tika, ko te mōhio ki te uara o te huri ā-ringa ko te whiriwhiri i tētahi rauemi pono ka tu tonu i roto i te whakamātautau o te wā. Ehara i te mea he kōhatu noa iho; koia te tūāpapa mō te whakarite i te tino tika i roto i te hanga me te ine.
