I roto i te hanga tino tika, e whai tikanga ana ia maikorone, ehara i te mea ko te tino tika te whāinga anake — he whai tonu. Ko te mahi a ngā taputapu matatau pēnei i ngā mīhini ine taunga (CMM), ngā taputapu whatu, me ngā pūnaha tuhi haurua-ira e whakawhirinaki nui ana ki tētahi turanga puku engari he mea nui: te papa granite. Ko tōna papatahi mata e tautuhi ana i ngā rohe ine o te pūnaha katoa. Ahakoa ko ngā mīhini CNC matatau te mea nui rawa atu i ngā raina whakaputa hou, ko te taahiraa whakamutunga ki te whakatutuki i te tika iti-maikorone i roto i ngā papa granite e whakawhirinaki tonu ana ki ngā ringa tupato o ngā tohunga mahi toi mohio.
Ehara tēnei i te taonga tuku iho o mua — he hononga whakamiharo i waenga i te pūtaiao, te hangarau, me te toi. Ko te huri ā-ringa te wāhanga whakamutunga me te wāhanga tino uaua o te hanga tika, kāore anō kia taea e te aunoatanga te whakakapi i te taurite, te pā, me te whakatau tirohanga a te tangata kua whakatikatikaina i roto i ngā tau maha o te mahi.
Ko te take matua e kore ai e taea te whakakapi i te huri ā-ringa, ko tōna kaha ahurei ki te whakatutuki i te whakatikatika hihiri me te papatahi tino. Ahakoa te matatau o te miihini CNC, ka mahi tonu i roto i ngā rohe tika o ōna ara ārahi me ngā pūnaha miihini. He rerekē, ka whai te huri ā-ringa i tētahi tukanga urupare wā-tūturu - he porowhita tonu o te ine, te tātari, me te whakatika. Ka whakamahia e ngā tohunga hangarau ngā taputapu pēnei i ngā taumata hiko, ngā autocollimator, me ngā interferometer laser hei kite i ngā rerekētanga iti, me te whakatika i te pēhanga me ngā tauira nekehanga hei whakautu. Mā tēnei tukanga auau ka taea e rātou te whakakore i ngā tihi me ngā awaawa moroiti puta noa i te mata, ka tutuki te papatahi ā-ao e kore e taea e ngā mīhini hou te tārua.
Haunga te tika, he mea nui te huri ā-ringa ki te whakaū i te ahotea o roto. Ko te karāneti, hei rauemi tūturu, ka mau tonu ngā kaha o roto mai i ngā hanganga whenua me ngā mahi miihini. Ka taea e te tapahi miihini kaha te whakararuraru i tēnei taurite ngawari, ka arahi ki te whakarerekētanga roa. Heoi, ka mahia te huri ā-ringa i raro i te pēhanga iti me te whakaputa wera iti. Ka mahihia ia paparanga me te tupato, kātahi ka okioki me te ine i roto i ngā rā, i ngā wiki rānei. Mā tēnei manawataki puhoi me te āta whakaaro ka taea e te rauemi te tuku noa i te ahotea, ka whakarite i te pumau hanganga e mau tonu ana i roto i ngā tau o te mahi.
Ko tētahi atu hua nui o te huri ā-ringa ko te waihanga i tētahi mata isotropic — he kakano ōrite, kāore he aronga whāiti. Kāore i rite ki te huri mīhini, e waiho ana i ngā tohu pakū rārangi, ka whakamahia e ngā tikanga ā-ringa ngā nekehanga whakahaeretia, maha-aronga pērā i te ahua-waru me ngā whiu porowhita. Ko te hua he mata he waku pumau me te auau i ngā ahunga katoa, he mea nui mō ngā ine tika me te nekehanga maeneene o te wāhanga i te wā e mahi tika ana.
Heoi anō, ko te koretake o te hanganga o te karāneti e hiahia ana ki te māramatanga tangata. Kei roto i te karāneti ngā kohuke pēnei i te quartz, te feldspar, me te mika, he rerekē te pakeke o ia mea. Ka hurihia e te mīhini, ka tere ake te pakaru o ngā kohuke ngohengohe, ka puta ake ngā mea pakeke, ka hanga he āhua kore taurite. Ka taea e ngā tohunga mahi toi te rongo i ēnei rerekētanga ngawari mā te taputapu huri, ka whakarerekē i tō rātou kaha me te tikanga kia puta ai he āhua ōrite, kiato, ā, kia ātete ki te pakaru.
Ko te tikanga, ehara te mahi huri ā-ringa i te whakamuri engari he whakaata i te pūkenga o te tangata ki ngā rauemi tino tika. Ka honoa te āputa i waenga i te koretake o te taiao me te tino pai o te hangarau. Ka taea e ngā mīhini CNC te mahi i te tapahi taumaha me te tere me te rite tonu, engari ko te tohunga tangata te mea e hoatu ana i te pa whakamutunga - te huri i te kohatu mata hei taputapu tino tika e taea ai te tautuhi i ngā rohe o te ine ine o ēnei rā.
Ko te whiriwhiri i tētahi papa kōhatu i hangaia mā te whakaoti ā-ringa ehara i te mea he tikanga tuku iho noa iho; he haumitanga ki te tika pumau, te pumau mō te wā roa, me te pono e tu atu ana i te wā. Kei muri i ia mata kōhatu papatahi tino pai kei reira te tohungatanga me te manawanui o ngā tohunga toi e hanga ana i te kōhatu ki te taumata maikorona - e whakaatu ana ahakoa i tēnei wā o te aunoatanga, ko te ringa tangata tonu te taputapu tino tika o ngā mea katoa.
