Mena kua hikoi koe i roto i tētahi whare hanga tino tika, i tētahi taiwhanga whakatikatika, i tētahi rūma whakahaere kounga rererangi rānei, kua kite pea koe i tētahi pereti mata karāhe e mahi ana. Ko ēnei pereti kohatu māori taumaha, pōuriuri kei waenganui o te ine inenga, e mahi ana hei papa tohutoro turanga e tangohia ai ngā inenga maha i ia rā. Kei runga i a rātou ngā ine teitei. Ka whakatauritehia ngā pānui e ngā tohu waea ki a rātou. Ka whakamahia e ngā mīhini ine taunga hei mata raraunga. I roto i ngā ahumahi e taea ai e te maikorona o te hapa te rerekētanga i waenga i te wāhanga rererangi angitu me te rahunga, ko te pereti mata karāhe te "ira o te pono."
Ahakoa tōna hiranga, he mea ngaro tonu ngā pereti mata karāhe ki te tini o ngā kaihoko, tae atu ki ētahi miihini e whakamahi ana i ia rā. Ko tētahi o ngā pūtake o te whakapoauau ko te pūnaha whakatauranga. He aha te tikanga o te Taumata 00? He aha tōna rerekētanga mai i te Taumata 0, Taumata 1 rānei? Āhea koe me whiriwhiri i tētahi i tētahi? He pai ake te taumata teitei ake? Koinei tonu ngā pātai e whakatakotoria ana e tēnei tuhinga hei whakautu i roto i te reo māmā, whai hua.
He mahi te ine tika hei whakahaere i te koretake. Ia wā ka whakatakotoria e te tohunga hangarau he ine ki runga i te pereti mata, ā, ka tuhia he pānui, ko taua pānui he rite tonu ki te mata tohutoro i raro iho. Mena ka peka ke te pereti i te papa tino tika mā te maha o ngā maikorona, ka tāpiri tika aua maikorona ki te koretake o te ine. I roto i te ao e hiahiatia ana e ngā manawanui miihini hou te tika o te maikorona kotahi-mati, ko te pereti mata e "tata ana" kāore pea e tata ana.
Koinei te wāhi e uru mai ai ngā tohu tika. Ko te tohu tika he whakarōpūtanga e whakaatu ana i te rerekētanga mōrahi e whakaaetia ana mai i te papatahi mō tētahi pereti mata, i runga i tōna rahi me te whakamahinga e hiahiatia ana. Ehara te tohu i te mea tūpono noa; kua tautuhia e ngā paerewa e mōhiotia ana e te ao e whakaatu ana i ngā uara manawanui tika, ngā tikanga whakamātautau, me ngā whakaritenga rauemi. He mea nui te mārama ki ēnei tohu mō te hunga e whai kawenga ana ki te whiriwhiri i ngā taputapu ine, te hoahoa i ngā tukanga whakahaere kounga, te whakarite rānei kia tutuki i ngā ture ahumahi.
Ko te paerewa o te ao e tino kitea ana mō ngā pereti mata karāhe ko te ISO 8512-2, ko "Ngā pereti mata — Wāhanga 2: Karāhe." I whakaputaina e te International Organization for Standardization, e tautuhi ana tēnei paerewa i ngā whakaritenga mō ngā pereti mata karāhe tapawhā, tapawhā rānei, mai i te 160 mm ki te 100 mm ki te 2500 mm ki te 1600 mm. E whakatū ana i ngā taumata tika e whā: Te Taumata 0, Te Taumata 1, Te Taumata 2, me te Taumata 3, ko te Taumata 0 te tohu o te tino tika, ā, ko te Taumata 3 te tohu o te manawanui tino ngāwari.
I te wā kotahi, ka whakamahia e te paerewa Tiamana DIN 876 tētahi tohu paku rerekē e whakauru ana i te Tau 00 i runga ake i te Tau 0. He mea noa tēnei pūnaha puta noa i Ūropi me Āhia, ā, ko te tikanga ka tohua e ngā kaihanga ngā pereti hei Tau 00, 0, 1, 2 rānei. Ko te tohu Tau 00 e tohu ana i tētahi manawanui pakari ake i te Tau 0, e tata ana ki te taumata o te tika e hiahiatia ana i roto i ngā taiwhanga whakatikatika tuatahi kei reira ngā paerewa ine ā-motu e mau tonu ana.
I tērā taha o te Moana Ataratiki, ko te mākete o Amerika i whakawhirinaki ki te Federal Specification GGG-P-463c me tōna uri, ASME B89.3.7-2013. E tautuhia ana e ēnei tuhinga e toru ngā tohu AA, A, me B, ko te Tohu AA te paerewa taiwhanga, ko te Tohu A te paerewa tirotiro, ā, ko te Tohu B te paerewa rūma taputapu, te paerewa papa mahi rānei. I roto i ngā kupu mahi, e rite ana te Tohu AA ki te Tohu 00 i raro i te DIN, e rite ana te Tohu A ki te Tohu 0, ā, e rite ana te Tohu B ki te Tohu 1. Ahakoa he rerekē ngā uara manawanui tuturu nā ngā huringa wae me te whakaawhiwhi, he rite tonu te hiranga ariā puta noa i ngā paerewa matua katoa.
I mua i te ruku ki ngā taumata motuhake, he mea nui kia mārama ko te tika o te pereti mata e rua ngā āhuatanga motuhake engari he rite tonu te hiranga. Ko te tuatahi ko te papatahi whānui, e pā ana ki te rerekētanga mōrahi mai i te papa tino tika puta noa i te mata mahi katoa. Ko te tuarua ko te rerekētanga ā-rohe o te papatahi, e kiia ana i ētahi wā ko te pānui tāruarua. Ka ine tēnei i te nui o te rerekētanga o te mata i roto i tētahi wāhi iti 250 mm ki te 250 mm.
He mea nui rawa ngā āhuatanga e rua i roto i te mahi. Whakaarohia tētahi horopaki ina tutuki te pereti mata i te whakatakotoranga papatahi whānui engari he nui te ngaru o te rohe. Ina whakatakotoria he ine teitei ki tētahi wāhi o te pereti, tera pea ka tau ki runga i tētahi tihi, ko tētahi mea mahi i inehia tata kei roto i tētahi awaawa. Ko te hapa ine ka puta he nui rawa atu i te mea e kīia ana e te manawanui kua whakahuatia. Koia te take e whakamanahia ai e ngā kaihanga rongonui me ngā taiwhanga whakatikatika ngā pereti ki ngā whakatakotoranga papatahi whānui me ngā rerekētanga rohe.
Ko te taumata 00 te tihi o te hanga pereti mata karāhe arumoni. I hangaia ēnei pereti mō ngā taiao whakahaeretia, ā, he tino whakahaeretia te pāmahana, te haumākū, me te wiri. Ka kitea e koe ngā pereti taumata 00 i roto i ngā whare ine ine ā-motu, i ngā taiwhanga whakatikatika tuatahi, me ngā whare hanga tino tika, ā, ka inehia ngā taunga i roto i ngā awhe iti-micron.
Ko ngā ātete papatahi mō ngā pereti Taumata 00 te mea tino uaua o ngā pereti mata karāhe e wātea ana i te mākete. Mō tētahi pereti 630 mm te whānui, 630 mm te whānui, ko te ātete papatahi whānui e tata ana ki te 4 maikorona, engari kaua e neke ake i te 3 maikorona te ātete rerekētanga ā-rohe mō tētahi horahanga 250 mm te whānui, 250 mm te whānui. Hei whakamārama i tēnā, ko te whānui o te makawe tangata he 70 maikorona te toharite. Ko ngā pereti Taumata 00 he papatahi, tae atu ki te kotahi-rua tekau o te makawe tangata puta noa i tōna mata katoa.
Hei whakatutuki i tēnei taumata o te tika, me tino tupato te hanga. Me whiriwhiri te karāhe mata kia rite te tohatoha o ngā kohuke, kia iti te ahotea o roto, kia tino pakeke hoki. Whai muri i te tapahi me te huri tuatahi, ka pāngia te pereti e tētahi tukanga whakapiri roa, ka tangohia haeretia e ngā tohunga hangarau ngā wāhi teitei moroiti mā te whakamahi i ngā mea whakakoi pai haere. Ka roa ake pea tēnei tukanga i te hanga i tētahi pereti Tau 0. Whai muri i te whakapiri, ka tirotirohia ia pereti Tau 00 mā te whakamahi i ngā taumata hiko, ngā ine whakawhiti laser, ngā ine whakakoi-aunoa rānei hei manatoko i te tutuki.
He motuhake ngā whakamahinga mō ngā pereti Tau 00, ā, he maha ngā wā he mea nui te mahi. Ka mahi ēnei hei mata tohutoro mō te whakatikatika i ētahi atu paerewa ine, mō te mahi whakatikatika i ngā wāhanga whatu, me te tautoko i ngā mīhini ine taunga i roto i te hanga haurua-ira me te rererangi. Ko te whakamahi i tētahi pereti Tau 00 mō te whakahaere kounga noa i runga i te papa toa he rite ki te whakamahi i tētahi tauine taiwhanga tika hei pauna i ngā putea hoko kai - he mea whakamiharo te hangarau engari kāore e tika ana.
Ko te taumata 0 kei waenganui i te tino pai o te taiwhanga me te whaihua o te papa mahi. Ko ēnei pereti taumata tirotiro ngā mea tino pai o te hanga tika, e kitea ana i roto i ngā taiwhanga whakahaere kounga, i ngā teihana tirotiro huihuinga whakamutunga, me ngā taiao miihini manawanui-teitei huri noa i te ao. Ka tukuna e rātou te tika e ranea ana mō te nuinga o ngā mahi ine ahumahi, me te noho pakari tonu hei whakahaere i ngā āhuatanga tūturu o te whakamahinga o ia rā.
Mō te rahi o te pereti 630 mm te whānui, 630 mm te whānui, ko ngā whakaritenga o te Wāhanga 0 e āhei ana ki te ātete papatahi whānui o te 5 maikorona me te ātete rerekētanga ā-rohe o te 3.5 maikorona mō tētahi horahanga 250 mm te whānui, 250 mm te whānui. Ahakoa he iti ake te uaua o tēnei i te Wāhanga 00, he tino papatahi tonu tōna mata — he papatahi rawa atu i te mea ka taea te hanga i tētahi wāhanga whakarewa mīhini me te kore he huri motuhake.
Ko ngā painga mahi a ngā pereti Taumata 0 kei tua atu i ō rātou whakaritenga tika. Kāore i te tino pāngia e ngā rerekētanga iti o te taiao i ngā pereti Taumata 00, ā, he pai ake mō ngā whare kāore he mana whakahaere pāmahana tino tika. Ka mau tonu tō rātou tika i raro i ngā huringa uta me te tango i ngā mea e rite ana ki ngā taiao tirotiro whakaputa. Ā, nā te mea he iti ake te kaha o te tukanga whakapiri, kei te wātea mai i ngā utu e taea ana te utu, me te whakarato tonu i te pono o te taumata ngaio.
Ko ngā pereti Taumata 0 te mea pai rawa atu mō ngā teihana whakahaere kounga whānui, te manatoko i ngā wāhanga mīhini ki ngā ātete hangarau, me te tirotiro huihuinga whakamutunga i roto i ngā ahumahi pēnei i te hanga motuka, te hanga taputapu hauora, me te huihuinga mīhini tino tika. Mena ka inehia ō ātete ki roto i ngā maikorona, ā, he iti te tahua koretake o tō ine engari kāore i te tino nui, ko te Taumata 0 te whakautu tika i te nuinga o te wā. Ka whakaratohia he tawhiti haumaru nui ake i te nuinga o ngā ātete whakaputa me te kore e pāngia e te utu nui me te aro ki te taiao o te Taumata 00.
Ko te Reanga 1, e kiia ana i ētahi wā ko te reanga rūma taputapu, he mea hanga mō ngā mahi tirotiro whakaputa me te tirotiro whānui i roto i ngā taiao hangahanga. Ka whakarērea e ēnei pereti te tika o te papatahi hei utu mō te roa me te penapena, he mea pai mō ngā papa toa me ngā awheawhe ina kore e hiahiatia he tika iti iho i te maikorona engari me whai mata tohutoro pono tonu.
Ko te pereti Reanga 1, 630 mm te whānui, 630 mm te whānui, he rite ki te 10 maikorona te whānui, ā, ko te whānui he rite ki te 7 maikorona te whānui mō tētahi horahanga 250 mm te whānui, 250 mm te whānui. He tino papatahi tonu tēnei e ai ki ngā paerewa noa, engari he hekenga kitea mai i te Reanga 0. Hei whakataurite, ko te matotoru o tētahi pepa paerewa he tata ki te 100 maikorona. Tērā pea ka rerekē te papatahi o tētahi pereti Reanga 1 i te tino papatahi mā te tata ki te kotahi-tekau o te rau pepa puta noa i tōna mata katoa.
Ko ngā pereti Taumata 1 e whakamahia whānuitia ana mō ngā mahi tahora me te tohu, te tirotiro tuatahi i ngā wāhanga mīhini, te whakatū i ngā jig me ngā taputapu, me te tirotiro whakaputa whānui i te wā e inehia ai ngā taunga i roto i ngā haurua o te mirimita kaua ki te maikorona. He tino pai ēnei mō ngā taiao he iti ake te pai o te whakahaere āhuarangi, i te wā e whakarato ana te taunga whānui ake i te ārai mahi ki ngā rerekētanga pāmahana iti me te kakahu o te mata.
Ka mārama ake ngā hua o te whiriwhiri i tētahi taumata i tētahi atu ina whakaarohia te horapa o ngā hapa papatahi puta noa i te mekameka ine. Ko ia inenga i mahia ki runga i te pereti mata ka mau te koretake o te papatahi o te pereti hei takoha taketake. Mena kei te mahi koe me tētahi pereti Tau 0 he 5-micron te ātete papatahi, ā, ka whakakotahi koe i tēnā me tētahi ine teitei he 3-micron te koretake o te ine, kua tata kē tō koretake katoa ki te 8 microns i mua i te ine i te mea mahi. Mena he 20 microns tō ātete wāhanga, he pai te tawhiti haumaru. Mena he 10 microns, kua raru kē koe.
Ko te horapa o te koretake te take i whakamahia ai te ture matua i roto i te hanga tino tika, arā, ko te whiriwhiri i tētahi pereti mata e kore e neke atu i te kotahi haurima ki te kotahi tekau o te manawanui papatahi o te manawanui mahi e ngana ana koe ki te manatoko. Ehara i te mea he pai ake ngā inenga o tētahi pereti kounga teitei ake; engari ko te iti o te takoha koretake mai i tētahi pereti kounga teitei ake ka nui ake te wāhi i roto i tō tahua koretake inenga katoa.
Ko te whiriwhiri i waenga i te Tau 00, te Tau 0, me te Tau 1 he whakatau e ahu mai ana i ngā āhuatanga matua e toru: ko ngā whakaritenga tika o āu mahi ine, ko ngā āhuatanga taiao o tō whare, me tō tahua e wātea ana.
Mena kei te whakahaere koe i tētahi taiwhanga whakatikatika, i tētahi whare hanga tino tika rānei, e inehia ana ngā taunga i roto i ngā awhe iti-micron, ā, kei tō taiao te mana whakahaere o te āhuarangi, ko te Wāhanga 00 te kōwhiringa tika. Ka whakamanahia te haumitanga e te āhua tino nui o ō inenga me ngā whakaritenga ture pakari me tutuki e koe.
Mena kei te whakahaere koe i tētahi mahi hanga tino tika, kei reira ngā taunga kei roto i te awhe o te 10 ki te 50 maikorone, kei reira koe e mahi ana i ngā tirotiro whakamutunga me te manatoko kounga, ā, kei reira koe e hiahia ana ki tētahi taputapu mahi pono e kore e hiahia ki ngā mana whakahaere taiao tino kaha, ko te Wāhanga 0 te kōwhiringa tika. Ka whakaratohia e ia te tino tika e hiahiatia ana e te nuinga o ngā tono ahumahi me te kore e tino whakarite i ngā mahi kāore e hiahiatia ana.
Mena ko te tahora, te tohu, te tirotiro tuatahi, te tirotiro whakaputa rānei te mea nui rawa atu e hiahiatia ana e koe, ina inehia ngā taunga ki ngā haurua mirimita, he tino pai te uara o ngā pereti Taumata 1. He pakari, he utu tika, ā, he tika hoki mō te nuinga o ngā mahi awheawhe me ngā mahi papa whakaputa.
Ko tētahi hapa noa ko te whakaaro aunoa ko te Wāhanga 00 te kōwhiringa haumaru ahakoa te whakamahinga. Ahakoa he iti ake ngā āwangawanga o ngā wāhanga teitei ake, me kaha ake hoki ngā āhuatanga taiao, me āta whakahaere, me auau ake te whakatikatika kia mau tonu ai ā rātou whakaritenga. Mā te whakatakoto i tētahi pereti Wāhanga 00 ki runga i te papa o te toa me ngā huringa pāmahana me te whakamahinga nui o ia rā, tera pea ka tere te heke o tōna tika - me te maumauria nui o ngā whakapaunga.
Ko te whiwhi i tētahi pereti mata kua tohua tika te taahiraa tuatahi ki te whakarite i te tika o te ine. Pērā i ngā taputapu tika katoa, me whakatikatika anō ngā pereti mata karāhe i ia wā kia mōhio ai kāore i nekeneke te papatahi nā te kakahu, ngā pānga wera, ngā kino tūpono rānei. Ko te wā whakatikatika e taunakitia ana ka whakawhirinaki ki te kounga o te pereti, tōna kaha o te whakamahinga, me te hiranga o ngā inenga i mahia ki runga. Mō te nuinga o ngā pereti Taumata 0 me te Taumata 1, he rawaka te whakatikatika ā-tau. Mō ngā pereti Taumata 00 i roto i ngā tono tino tika, he maha ngā wā e taunakitia ana te whakatikatika ā-haurua-tau.
Ko te whakatikatika he ine i te papatahi whānui me te rerekētanga ā-rohe mā te whakamahi i ngā taputapu ka taea te whai i ngā taumata hiko, ngā ine whakawhiti laser, ngā ine pānui tāruarua rānei. Ka tuhia e te pūrongo whakatikatika whaimana te rerekētanga papatahi tūturu i inehia puta noa i te mata, ā, ka taea te whai i ngā paerewa ine ā-motu. He maha ngā pūnaha whakahaere kounga, tae atu ki te ISO 9001 me te ISO 17025, e hiahia ana kia whai tiwhikete whakatikatika hou hei whakaritenga mō te tutuki i ngā whakaritenga.
I waenganui i ngā whakatikatika, mā te tiaki tika ka roa ake te ora o te pereti. Me tiaki ngā pereti ki ngā taupoki ina kore e whakamahia, me horoi i ia wā hei tango i ngā paru whakakoi, ā, me ata whakahaere kia kore ai e pakaru, e pā kino rānei. Mā te tautoko i te pereti ki runga i tētahi tūnga tika me te tautoko kinematic e toru-ira ka ārai i te piko o te kaha ā-papa, ā, mā te whakanoho i te tūnga kia tawhiti atu i ngā pūtake wera me ngā mīhini wiri ka mau tonu te papatahi.
He maha ngā kōrero pakiwaitara e pā ana ki ngā tohu o te pereti mata karāhe ka arahi pea ki ngā hapa utu nui i roto i te whiriwhiri me te whakamahinga. Ko te tuatahi, ko te mea tino morearea ko te whakaaro he pai ake ngā tohu teitei ahakoa te whakamahinga. Ahakoa he tino kaha ngā manawanui o ngā pereti Tohu 00, ko rātou anō hoki te mea tino tairongo ki ngā āhuatanga taiao, ā, ko rātou te mea tino utu nui ki te tiaki. Ko te whiriwhiri i tētahi pereti Tohu 00 mō tētahi whakamahinga e hiahia ana ki te tika Tohu 1 anake, ehara i te mea he āputa haumaru - he tohatoha rauemi koretake, ā, tera pea ka kino ake te mahi i roto i tētahi taiao kāore i te tino pai.
Ko tētahi atu whakaaro hē ko te whakaaro ko te papatahi o te pereti anake te mea e tika ai te ine. E ai ki te kōrero i mua ake nei, me whai whakaaro ki te papatahi whānui me te rerekētanga ā-rohe. Ko te pereti e tutuki ana i te ātete papatahi whānui engari he nui te ngaru ā-rohe ka puta he hapa ine e nui atu ana i tana whakatakotoranga kua whakaritea.
Ko te tuatoru o ngā pūrākau e whakataurite ana i te tae o te karāneti ki tōna kounga. Ko te mea pono, ko te hanganga kohuke o te karāneti — tae atu ki te nui o te kuata, te hanganga o te kōhatu, me te ōritetanga — te mea e whakatau ana i tōna pai mō ngā tono tika, ehara i te mea ko tōna tae. Ka taea e te karāneti pango, te karāneti māwhero, me te karāneti hina te hanga pereti mata pai mena ka tutuki i a rātou ngā whakaritenga rauemi ōrite.
Hei whakamutunga, he mea tika kia mōhiotia ahakoa te pereti karāhe kounga teitei rawa, kāore e taea te pupuri i tōna tika kua tohua mō ake tonu atu me te kore he tautoko tika, he whakahaere taiao, he whakatikatika anō i ia wā. He hē te whakaaro "kāore te karāhe e rerekē". Ahakoa he tino pumau te karāhe ki te whakataurite ki ngā konganuku, kāore i te ātete ki ngā pānga tāpiri o te kakahu, te huringa wera, me te ahotea miihini.
He tino māmā noa iho ngā pereti mata karāneti. I te tirohanga tuatahi, he rite tonu ki ngā kōhatu papatahi. Ko te mea pono, koinei te tūāpapa o te ine inenga - he taonga tino tika e whakatau tika ana i te pono o ia inenga e mahia ana ki runga. Ehara i te mea he mahi mātauranga te mārama ki ngā tohu tika, mai i te Tohu 00 ki te Tohu 1. He mea mahi tēnei mā te hunga e whai kawenga ana ki te whakarite i te kounga inenga, te whakahaere i ngā utu whakaputa, te pupuri rānei i te tutuki i ngā paerewa kounga o te ao.
Ko te mea nui, ehara i te mea he pai ake tētahi tohu i tētahi atu. Engari, ko te tohu tika ko te mea e rite ana ki ō whakaritenga ine tuturu, me te noho hototahi tonu ki ngā āhuatanga taiao me tō tahua. Ka mahi te Tohu 00 ki ngā taiwhanga whakatikatika tino uaua me te tino tika e tata ana ki te mea whakamiharo. Ka mahi te Tohu 0 ki te nuinga o ngā taiao hanga tino tika me te tino tika, pono hoki. Ka mahi te Tohu 1 ki ngā taiao awheawhe me ngā taiao whakaputa e rite ana te hiranga o te pakari me te ōhanga ki te tino pai o te ariā.
Mā te whakataurite i te pereti ki te mahi, kaua ki te huri ki te taumata teitei rawa atu, ka tutuki i a koe te taurite pai o te tika, te utu, me te pono mō te wā roa. I roto i te ine tika, pērā i te nuinga o ngā kaupapa hangarau, kāore te otinga tino pai i te mea tino uaua - ko te mea e pai ana ki te raruraru. Kōwhiria te taumata e tutuki ana i ō hiahia, tiakina kia tika, whakatauritehia i ia wā, ā, ka whai turanga pono koe mō ia inenga e whai ake nei.
