Ina tono te miihini kounga i tētahi pereti mata karāhe kua whakatauria ki te "Grade 0" me te "Grade 00" rānei, ehara i te mea he kōhatu papatahi anake tā rātou e hoko ana. Kei te hoko rātou i tētahi tohutoro kua tuhia, kua whakamanahia, ā, ka taea te whai - ko tētahi e tautoko ana i ngā inenga katoa e mahia ana ki taua tohutoro. Engari he aha te tikanga o ēnei tohu tohu? Me pēhea te ine me te manatoko i te papatahi i te taumata iti-micron? Ā, he aha i rerekē ai ngā whakaritenga o ngā paerewa i tukuna e te komiti DIN o Tiamana, te American Society of Mechanical Engineers, te JIS o Hapani, te British Standards Institution, me ētahi atu whakahaere ā-motu - ahakoa kei te ngana katoa rātou ki te tautuhi i te āhuatanga ā-tinana kotahi?
Ehara i te mea he pātai mātauranga noa iho ēnei. Mō te miihini hoko e whiriwhiri ana i tētahi pereti mata mō tētahi taiwhanga whakatikatika, mō te kaihoahoa taputapu e tohu ana i tētahi ripanga rātaka CMM, mō te kaiwhakahaere kounga rānei e arotake ana i tētahi kaiwhakarato, he mea nui te mārama ki te matū kei muri i ngā tohu tiwhikete. Ko te tohu māka me te kore e mārama ki tōna tikanga, me pēhea te ine, me te paerewa e pā ana, ehara i te taurangi kounga - he tapanga noa iho.
Te Tikanga Tuturu o te "Papatahi" i roto i te Ine Tika
I roto i te horopaki o ngā pereti mata tino tika, he whakamāramatanga hangarau motuhake tō te papatahi e rerekē ana i te whakamahinga o te reo. Ka tautuhia he papatahi te mata e ai ki tētahi whakatakotoranga mēnā ka taka ngā pūwāhi katoa o taua mata ki roto i ngā papa tohutoro whakarara e rua e wehea ana e te ātete papatahi kua tohua.
He nui ngā pānga o tēnei whakamāramatanga. Tuatahi, he whakatakotoranga ā-ao — e pā ana ki te mata katoa, kaua ko ngā pūwāhi kua tohua anake. Ko te pereti mata he papatahi tino pai i waenganui engari he paku piko ki ngā taha ka kore e taea te whakatakotoranga papatahi ā-ao, ahakoa he papatahi te āhua o tētahi rohe ā-rohe ina tirohia mā te whakamahi i tētahi tohu whakamātautau poto. Tuarua, ko te uara manawanui e tohu ana i te whānui o te rohe i waenganui i ngā papa e rua e herea ana, ehara i te rerekētanga mai i tētahi inenga ingoa. Tuatoru, ko te tikanga ine e whakamahia ana hei manatoko i te papatahi me whai i ngā tiwhikete whakatikatika — ko te tikanga he tiwhikete whakatikatika kei ngā taputapu ine e whakamahia ana e hono ana i tō rātou tika mā roto i tētahi mekameka kore whati ki tētahi paerewa ine ā-motu, ā-ao rānei.
I te taumata o te tika e hiahiatia ana mō ngā pereti mata taumata 00 (e kiia ana ko te taumata taiwhanga), ka taka ngā ātete ki te awhe o te 1–3 maikiromita i runga ake i te mata mahi. Ko te whakatutuki i ngā inenga i tēnei taumata o te tika me whakamahi i te ine whakawhiti laser, i ngā autocollimator hiko, i ngā taumata hiko tika rānei — kāore e taea e ngā ine mata tuku iho, ngā tohu whakamātautau rānei te whakatau pono i ēnei ātete.
Ngā Paerewa Matua o te Ao mō ngā Pereti Mata Granite
DIN 876 (Tiamana)
Nā te German Institute for Standardization (Deutsches Institut für Normung) i whakaputa te DIN 876 hei whakaritenga e whakahaere ana i ngā pereti mata tika e whakamahia ana mō ngā whakamātautau me ngā kaupapa ine. E whā ngā tohu tika e tautuhia ana e tēnei paerewa:
- Taumata 3 (Taumata Awheawhe): Ko te taumata iti rawa te tika, e whakamahia ana mō te whakamahinga whānui i roto i te awheawhe ina e ranea ana te tika taurite.
- Taumata 2 (Taumata Awheawhe): Tika waenga mō te tirotiro awheawhe me te mahi tahora.
- Taumata 1 (Taumata Tirotiro): He tino tika mō ngā taiwhanga whakahaere kounga me ngā taiwhanga tirotiro.
- Taumata 0 (Taumata Tika): He tino tika te mahi mō te ine me te whakatikatika tika.
- Tau 00 (Tau Tohutoro): Ko te tau teitei rawa, e rāhuitia ana mō ngā taiwhanga whakatikatika, ngā rūma paerewa, me ngā tono e whakamahia ai te pereti mata hei tohutoro ine matua.
E whakamārama ana te DIN 876 i ngā āheinga papatahi hei pānga ki ngā inenga ingoa o te pereti, me te whakawhāiti i ngā āheinga mō ngā pereti nunui (nā te mea he uaua ake te pupuri i te papatahi ōrite ki runga i te wāhi nui ake). E whakamārama ana hoki i ngā whakaritenga mō te whakaotinga mata, te kounga o te taha, te rauemi (me tutuki i te kirikiri ngā paearu matotoru me te pakeke kua tohua), me ngā āhuatanga taiao e tika ana kia mahia te ine.
E whakamahia whānuitia ana te DIN 876 puta noa i te ahumahi Pākehā, ā, e whakaaetia ana hoki hei paerewa tohutoro i roto i te maha o ngā mākete ehara i te Pākehā. He maha ngā kaiwhakarato o te ao o ngā taputapu tika e tohu ana i ngā tohu DIN 876 ina tautuhia ana ngā whakaritenga pereti mata i roto i ā rātou tuhinga taputapu.
ASME B89.3.7 (Te Hononga o Amerika)
Ko te paerewa B89.3.7 o te American Society of Mechanical Engineers te paerewa matua o Amerika mō ngā pereti mata karāhe. E toru ngā taumata e tautuhia ana:
- Taiwhanga Taumata: Te tika teitei rawa atu, he rite ki te DIN Taumata 00 pea.
- Tirotiro Taumata: Tika waenga, tata rite ki te Taumata DIN 0–1.
- Rūma Utauta Whakatauranga: He iti ake te tika mō te tirotiro papa whakaputa.
He rerekē te ASME B89.3.7 i te DIN 876 i roto i ētahi āhuatanga tikanga. E whakamahia ana te tikanga "pānui anō" mō te ine papatahi — arā, ka whakawhitia he taumata hiko, he autocollimator rānei puta noa i te mata i roto i tētahi tauira rārangi motuhake, ā, ka tukatukahia ngā pānui mā te pāngarau hei hanga anō i te āhua o te mata. E whakamārama ana te paerewa i te tauira whakawhiti tika me te tikanga tukatuka raraunga, e taea ai te tāruarua i ngā inenga e ai ki te ASME B89 i waenga i ngā taiwhanga rerekē me ngā pūnaha ine.
Ka aro nui hoki a ASME B89.3.7 ki te koretake o te ine, me te kī ko te koretake o te ine papatahi tonu he wāhanga iti noa iho o te manawanui e manatokohia ana. Mā tēnei whakaritenga ka ārai i te hapa noa o te whakamahi i ngā taputapu ine kāore i te tino tika hei manatoko i te whakatakotoranga e tirohia ana.
JIS B 7513 (Hapani)
E whai ana te Paerewa Ahumahi Hapanihi JIS B 7513 i tētahihanganga tohu(Taumata 0, Taumata 1, Taumata 2, Taumata 3) me ngā ātete papatahi e rite ana ki te pūnaha DIN 876. Ka aro nui te mahi ahumahi Hapanihi ki te auautanga o te ine me te tohu mātauranga o ngā kaimahi ine, e whakaata ana i te ahurea hangahanga e whakaarohia ana ko te ōritetanga o te tukanga me te pūkenga tangata he mea nui hei āhuatanga kounga.
E whakamahia whānuitia ana te JIS B 7513 e ngā kaihanga taputapu Hapanihi tae atu ki a THK, HIWIN, NSK, me Mitutoyo — he kamupene kei te horapa puta noa i te ao ā rātou aratohu raina, whāriki tika, me ngā taputapu ine. Ka tūtaki pinepine ngā kaihoahoa taputapu e mahi ana me ngā wāhanga mai i ngā kaiwhakarato Hapanihi ki ngā whakatakotoranga pereti mata JIS B 7513 i roto i ngā tuhinga huihuinga me te whakatikatika.
BS 817 (Te Hononga o Peretānia)
I whakaputaina te Paerewa o Peretānia BS 817 e te British Standards Institution, ā, e whakahaere ana i ngā pereti mata me ngā ripanga mō ngā kaupapa hangarau. Pērā i te DIN 876, e tautuhi ana i ngā taumata maha, e tohu ana hoki i ngā ātete papatahi me ngā whakaritenga rauemi. E whakamahia ana te BS 817 i roto i ngā horopaki hanga rererangi me te tiaki i te UK me ngā whenua e mau tonu ana ngā hononga hītori kaha ki ngā anga paerewa o Peretānia.
GOST 10905 (Rūhia)
E tohu ana te paerewa ā-motu o Ruhia, GOST 10905, i ngā pereti mata o te karāhe me te rino maka mō te ine me te tirotiro whānui. Koinei te tohutoro matua i roto i te ahumahi Ruhia me ngā rāngai hangarau o ngā whenua i whakamahi i ngā paerewa ahumahi o te wā o Sōviete. Mō ngā kaiwhakarato e mahi tahi ana me ngā kiritaki o Ruhia, o Ūropi ki te Rawhiti rānei, ka taea te tohu GOST hei whakaritenga hoko whaimana.
GB/T 4167 (Haina)
Ko te paerewa ā-motu a Haina, GB/T 4167, e tohu ana i ngā pereti mata me ngā tēpu mō ngā kaupapa ine whānui. Ko te hanganga tohu me ngā uara manawanui he mea hangai ki ngā paerewa matua o te ao, e whakaata ana i te whakaurunga o Haina ki ngā mekameka tuku hangahanga o te ao.
Te Ine i te Papatahi: Te Tikanga Mahi
He rerekē te tautuhi i te taumata papatahi; he rerekē te manatoko mā te ine tuturu. He maha ngā tikanga ine e whakamahia ana i roto i te mahi, he rerekē ngā āheinga me ngā herenga o ia tikanga.
Tikanga Matapihi Taumata Hiko
Ko te tikanga tino noa mō te manatoko i te papatahi o te pereti mata i roto i ngā tautuhinga whakaputa he whakamahi i tētahi taumata hiko tino tika (pērā i ngā mea i hangaia e WYLER o Switzerland, e Mahr rānei o Tiamana) e whakawhitihia ana puta noa i te mata i roto i tētahi tauira whatunga. Ka tangohia ngā pānui i ngā wā kua tautuhia i runga i tētahi raupapa rārangi e whiti ana i te mata i ngā taha e rua, tae atu ki ngā taha whakarara. Ka tukatukahia te huinga raraunga hua mā te pāngarau — mā te whakamahi i ngā tikanga pēnei i te taunga papa tapawhā iti rawa — hei whakatau i te rohe iti rawa kei roto ngā pūwāhi mata katoa.
He tikanga whai hua tēnei, he tere hoki, ā, ka taea te mahi mā te whakamahi i ngā taputapu ka taea te whai i ngā paerewa ā-motu mā roto i tētahi mekameka whakatikatika mārama. Ka taea e ngā taumata hiko me ngā whakataunga o te 0.1 arcsecond (e rite ana ki te 0.05 μm/m te aro) te whakatau i ngā rerekētanga papatahi i te taumata iti-micron. Koinei te tikanga paerewa kua tohua i roto i te ASME B89.3.7, ā, e whakaaetia whānuitia ana i raro i te nuinga o ngā paerewa ā-motu.
Inenga Whakawhitiwhiti Taiaho
Mō ngā tono tino tika — ngā pereti taiwhanga me ngā mata wāhanga tino tika e whakamahia ana i roto i ngā taputapu haurua-ira, taputapu whatu rānei — ka whakaratohia e te ine whakawhiti-ira te ine papatahi tino tika. Ka tukuna e te ine whakawhiti-ira he hihi mārama tino piripono puta noa i te mata e inehia ana. Ka hangaia e ngā rerekētanga o te teitei o te mata he rerekētanga roa-ara i roto i te hihi whakaata e hua ai ngā tawhā pokanoa, ka taea te tātari hei hanga anō i tētahi mahere teitei taipitopito o te mata katoa.
Ka taea e ngā inenga inenga laser hou e whakamahia ana i roto i te inenga tika — pērā i ērā i hangaia e Renishaw (UK) — te whakatutuki i ngā āwangawanga inenga i raro iho i te 100 nanometer. He mea nui tēnei āheinga mō te manatoko i te papatahi o ngā mata e whakamahia ana hei huānga tohutoro i roto i ngā taputapu inenga haurua-ira, ina me iti rawa ngā āwangawanga inenga kia kore ai e whai wāhi nui ki te tahua hapa katoa o te pūnaha.
Tikanga Whakakotahi-ā-roto
Ka tukuna e te autocollimator he hihi mārama ki runga i te whāinga whakaata e whakatakotoria ana ki te mata e inehia ana, ā, ka kitea te aronga koki o te whakaata (nō reira ko te pari ā-rohe o te mata) mā te tātari i te hihi whakahoki. Mā te whakawhiti i te whāinga whakaata puta noa i te mata i roto i tētahi tauira pūnaha me te whakauru i ngā pānui pari, ka taea te hanga anō i tētahi kōtaha teitei o te mata. Ka whakaratohia e ngā autocollimator me te taumira i roto i te awhe o te 0.01 arcseconds he huarahi whai hua hei whakakapi i te interferometry mō te ine i te papatahi i runga i ngā horahanga mata nui.
Te Taiao Ine: He aha te Hiranga o ngā Āhuatanga Whakahaeretia
Ko tētahi o ngā āhuatanga e tino warewarehia ana o te ine i te papatahi o te pereti mata ko te whakahaere taiao e hiahiatia ana hei whiwhi hua tika. Ehara te pereti mata karāhe i te poraka totoka kore mahi - he pūnaha wera e aro ana ki ngā urunga wera mai i ōna taiao, mai i te pa atu ki ētahi atu mea, tae atu ki te wera tinana o te tangata e ine ana.
Ka whānui ake te pereti karāhe 1-mita me te CTE o te 7 × 10⁻⁶ /°C mā te 7 maikiromita te roa mō ia pikinga pāmahana 1°C. Mena he 0.5°C te mahana ake o tētahi wāhanga o te pereti i tētahi atu — hei tauira, nā te mea he tata ake tētahi pito ki te pūhaumāota HVAC — ka whakapohehetia te mata e te pikinga wera e puta mai ana mā ētahi maikiromita, e huna ana, e whai ana rānei i ngā hapa āhuahanga tūturu.
Mā ngā taiwhanga ine ine tino tika ka aro atu ki tēnei mā te whakahaere taiao tino pakari:
- Kua whakapūmautia te pāmahana ki te ±0.1°C, neke atu rānei, i te taha o te uara tohutoro o te 20°C (te pāmahana tohutoro o te ao mō te ine i ngā āhuatanga e ai ki te ISO 1)
- Ka whakahaeretia te haumākū hei ārai i te mimiti o te makuku, te mimiti rānei i te mata o te kōhatu
- Te wehewehe wiri hei ārai i te hononga o ngā wiri o te papa ki roto i te pūnaha ine
- Te aukati i te pa tika i waenga i te pereti mata me tetahi mea kāore i te taurite te pāmahana ki te rūma.
Ko te paerewa ASME B89.6.2 e aro nui ana ki ngā āhuatanga taiao mō te ine tika, ā, me tirotiro tahi me te B89.3.7 ina whakatūria he taiao ine.
Ko ngā awaawa ārai-wiri e karapoti ana i te whare ine — kua whakakiia ki ngā rauemi whakaiti tika, ā, kua hangaia hei aukati i te horapa o te wiri whenua — ka tiaki anō i te taiao ine. Ko ngā whare e whakahaere ana i ngā inenga tino nui ka tohua hoki ngā kerēne o runga e rere puku ana, kāore e tuku i ngā nekehanga miihini ki te hanganga papa i te wā e whakahaerehia ana.
Te Whai Aroturukitanga Whakamātautau: Te Mekameka e Whakamana ana i ngā Mea Katoa
Ko te whai tikanga o te tiwhikete pereti mata he rite tonu ki te mekameka whakataurite i muri i ngā taputapu e whakamahia ana hei ine. Ko tēnei ariā — te whai i te āhua — he mea nui ki te ine ine o ēnei rā, ā, kua whakarārangihia ki ngā paerewa o te ao pērā i te ISO/IEC 17025, e whakahaere ana i te pūkenga o ngā taiwhanga whakamātautau me te whakataurite.
Ko te mahi a te aroturuki penei: ko te taumata hiko, ko te ine taumata laser rānei e whakamahia ana hei ine i te pereti mata me whakataurite ki tētahi paerewa tohutoro he tika ake i te taputapu. Ko taua paerewa tohutoro me whakataurite ki tētahi paerewa tika ake - ā, pērā tonu, mā roto i tētahi mekameka e mutu ana i tētahi paerewa ine tuatahi e puritia ana e tētahi whare ine ine ā-motu (NMI), pērā i te PTB i Tiamana, te NIST i te Hononga o Amerika, te NPL i te UK, te NIM rānei i Haina.
Kei ia hononga o tēnei mekameka he tiwhikete whakatikatika e whakaatu ana i te mea i inehia, te hua, te koretake o te ine, me te paerewa tohutoro i whakamahia. Mā te mekameka whai-tikanga katoa ka taea te hono i tetahi hua ine - tae atu ki te tiwhikete papatahi o te pereti mata - mā roto i ngā taunakitanga kua tuhia, ki ngā paerewa ā-tinana tuatahi e tautuhi ana i te mita me ētahi atu waeine SI.
Mō ngā kaihoko o ngā wāhanga karāhe tino tika me ngā pereti mata, ehara i te mea he mahi ā-ture te whakamana i tēnei mekameka whai i te mea tika — engari ko te whakamana hangarau e rite ana te tohu māka i runga i te tuhinga tiwhikete ki te āhuatanga tūturu, ine o te wāhanga, e manatokohia ana e ngā taputapu e manatokohia ana tōna tika.
Ngā Pānga Whai Hua mō ngā Kaihoahoa Taputapu me ngā Kaihanga Hoko
He pānga whai hua tō te mārama ki ngā paerewa papatahi mō te hunga e tohu ana i ngā wāhanga o te karāhe tino tika:
Tauritehia te tohu ki te tono. He nui atu i te rawaka te pereti mata tohu 0 mō te nuinga o ngā mahi tirotiro whakaputa. Mā te tohu i te tohu 00 mō tētahi tono kāore e hiahiatia taua taumata tika ka tāpirihia he utu me te kore e tāpirihia he kaha ine. I tetahi atu taha, mā te tohu i te tohu 1 mō tētahi ripanga raraunga CMM i roto i tētahi taiwhanga whakatikatika tika ka puta he hapa ine pūnaha ka whakakore i ngā mahi katoa e mahia ana i runga i taua mīhini.
Tauwhāitihia te paerewa. He whakatakotoranga kāore i oti te "pereti mata karāhe 0" mēnā kāore i te whakahuatia te paerewa e tika ana. He rite tonu ngā ātete papatahi o te DIN 876 Grade 0 me te ASME B89 Grade Inspection, engari kāore i te ōrite. Mō ngā mekameka tuku o te ao, me tauwhāiti tonu ko tēhea paerewa ā-motu, ā-ao rānei e whakahaere ana i te tohu tohu.
Me whai tuhinga whakatikatika katoa. Me whakaatu i roto i te tiwhikete te tikanga ine i whakamahia, ngā āhuatanga taiao i te wā ine ai, te taputapu motuhake i whakamahia me tōna tau tiwhikete whakatikatika, me te uara papatahi kua tatauhia me te koretake o te ine. Ko te tiwhikete e kī ana "e tutuki ana ki te Tohu 0" anake me te kore o ēnei mōhiohio tautoko, kāore e whakaatu i te whai i te whai.
Whakaarohia te wā ine. Kāore ngā pereti mata karāhe e pumau tonu — ka taea te pakaru i ngā wāhi e whakamahia nuitia ana, ā, me manatoko anō i tōna papatahi i ia wā. Kei te ASME B89.3.7 he aratohu mō ngā wā whakamātau anō i runga i te auau o te whakamahinga me te hiranga o ngā inenga i mahia.
Whakamutunga: Ngā Paerewa hei Tūāpapa mō te Whakawhirinaki
Ko ngā paerewa papatahi mō ngā pereti mata karāhe tino tika he pūnaha whakawhirinaki - he reo hangarau tahi e āhei ai te kaihoko i Singapore me te kaihanga i Tiamana (i Haina rānei) ki te whakaae ki te tikanga o tētahi whakatakotoranga, me pēhea te manatoko, me te koretake o te ine. Ko te mārama ki tēnei reo - ngā māka, ngā paerewa, ngā tikanga ine, me te mekameka whai - ka huri i tētahi whakataunga hoko mai i te peke whakapono ki tētahi whakatau hangarau e tautokona ana e ngā taunakitanga kua tuhia.
Mō ngā tono e whakatau ana te tika o te ine i te kounga o te hua, ehara tēnei i te mea whiriwhiri. Ko te hanganga kore e kitea e takoto ana te hanga tika.
