I roto i te hanga me te ine inenga tino tika, ko te pereti karāhe te turanga tino tika—te tohutoro kore-ira mō te ine inenga. Ko tōna kaha ki te pupuri i te papa tata-tino ehara i te mea he āhuatanga tūturu noa iho, engari ko te hua o tētahi tukanga hanga e tino whakahaerehia ana, ā, whai muri ko te tiaki auau, he mea whakarite. Engari he aha te haerenga whakamutunga e mahia ana e tētahi pereti karāhe hei whakatutuki i taua tino pai, ā, he aha ngā tikanga e tika ana hei pupuri i a ia? Mō ngā kaihangarau me ngā kaiwhakahaere kounga, ko te mārama ki te pūtake o tēnei tino tika me ngā mahi e tika ana hei tiaki i a ia he mea nui ki te pupuri i te kounga hanga.
Wāhanga 1: Te Tukanga Hanga—Te Papatahi o te Hangarau
Ko te haerenga o tētahi pereti karāhe, mai i tētahi poraka tapatapahi taratara ki tētahi pereti mata tohutoro, he raupapa o ngā wāhanga huri, whakatautau, me te whakaoti, ia wāhanga kua hangaia hei whakaiti haere i te hapa āhuahanga.
I te tīmatanga, i muri i te tapahi, ka tukuna te pereti ki te Hurihanga Taratara me te Hurihuri. Ka tangohia e tēnei wāhanga he nui o ngā rauemi hei whakatū i te āhua whakamutunga me te papatahi taratara. He mea nui, ka tukuna hoki e tēnei tukanga te nuinga o te ahotea toenga e hangai ana ki roto i te kōhatu i te wā e keri ana me te tapahi tuatahi. Mā te tuku i te pereti kia "noho" me te pumau anō i muri i ia taahiraa tango rauemi nui, ka āraihia e tātou te nekenekehanga ā-ahu ā muri ake nei, kia mau ai te pumau mō te wā roa.
Ko te tino panonitanga ka puta i te wā o Te Toi o te Whakakotahi Tika. Ko te whakakotahi te tukanga whakamutunga, tino motuhake e whakapai ana i te mata papatahi kia rite ki te mata tohutoro kua whakamanahia. Ehara tēnei i te huri ā-ringa; he mahi tino ātaahua, tere-iti, pēhanga teitei. Ka whakamahia e mātou ngā matū whakakoi pai, wetekina - he maha ngā wā he paraoa taimana - e iri ana i roto i te wai, e pania ana i waenga i te mata karāhe me te pereti whakakotahi rino pakari. Ka āta whakahaeretia te nekehanga kia pai ai te tango rauemi puta noa i te mata. Ko tēnei pānga toharite, e whakahokia ana ā-ringa me te ā-ringa i roto i ngā mahi auau, ka whakapai haere i te papatahi ki roto i ngā maikorona, ki raro iho rānei i ngā maikorona (e tutuki ana i ngā paerewa pakari pēnei i te ASME B89.3.7, ISO 8512 rānei). Ko te tika e tutukihia ana i konei ehara i te mea mō te mīhini engari mō te pūkenga o te kaiwhakahaere, e kite ana mātou he mahi nui, he mahi kore e taea te whakakapi.
Wāhanga 2: Te Tiaki—Te Kī ki te Tika Tonu
He taputapu tino tika te pereti mata karāhe, ehara i te papa mahi. Kia whakamanahia, ko tōna kaha ki te pupuri i te tika e whakawhirinaki katoa ana ki ngā tikanga a te kaiwhakamahi me te taiao.
Ko te Mana Whakahaere Taiao te mea nui rawa atu e pā ana ki te tika o te karāhe. Ahakoa he iti te tauwehenga whānui wera (COE) o te karāhe, ka taea e te rerekētanga pāmahana i waenga i ngā mata o runga me raro (he pikinga pāmahana poutū) te mea ka piko te pereti katoa, ka piko rānei. Nō reira, me waiho te pereti kia matara atu i te rā tika, i te hauhautanga o te hauhautanga, me ngā pūtake wera nui rawa atu. Ko te taiao pai ka pupuri i te pāmahana pumau 68°F ± 1°F (20℃ ± 0.5℃).
Mō te Tikanga Whakamahi me te Horoi, ko te whakamahinga ā-rohe tonu ka puta ai te pakaru kore taurite. Hei ārai i tēnei, ka tūtohu mātou kia hurihia te pereti i runga i tōna tūnga i ia wā, kia tohatohahia hoki te mahi ine puta noa i te mata. Me horoi noa i ia wā. Ka mahi te puehu me ngā paru angiangi hei mea whakakoi, ka tere ake te pakaru. Ko ngā kaihoroi karāhe motuhake, ko te waipiro isopropyl tino parakore rānei, me whakamahi noa. Kaua rawa e whakamahi i ngā hopi horoi whare, i ngā kaihoroi wai rānei ka waiho pea he toenga piri, mēnā he wai, ka whakamatao mō te wā poto ka whakapōturi i te mata. Ina noho mangere te pereti, me hipoki ki tētahi uhi ma, ngawari, kāore e whakakoi.
Hei whakamutunga, mō te Whakatikatika Anō me te Whakahoutanga, ahakoa te tino tiaki, kāore e taea te karo i te pakaru. I runga i te taumata whakamahinga (hei tauira, te Tau AA, A, B rānei) me te taumaha mahi, me whakatikatika anō te pereti mata karāhe i ia 6 ki te 36 marama. Ka whakamahia e te tohunga hangarau whaimana ngā taputapu pēnei i ngā autocollimators, ngā interferometers laser rānei hei mahere i te rerekētanga o te mata. Mena ka taka te pereti ki waho o tōna taumata manawanui, ka tukuna e ZHHIMG ngā ratonga whakahou a te tohunga. Ko tēnei tukanga ko te whakahoki mai i te hurihanga tika ki te papaanga, ki tō mātou whare rānei hei whakahoki mai i te papatahi taketake kua whakamanahia, me te tautuhi anō i te roa o te ora o te taputapu.
Mā te mārama ki te tukanga hanga nui, me te piri ki tētahi kaupapa tiaki pakari, ka taea e ngā kaiwhakamahi te whakarite kia noho tonu ā rātou pereti mata kirikiri hei turanga pono mō ā rātou whakaritenga kounga tika katoa, tekau tau ki muri.
