Kua whakangao moni koe ki tētahi mīhini ine taunga hou. Kua whakatikatikaina te pūmanawa. Kua whakamanahia ngā ine. Heoi anō, kei te rerekē ō inenga. Kāore i te nui rawa - he maikorona noa iho i konei, he haurua maikorona i reira. Engari i te ao o te inenga tino tika, ko taua rerekētanga te rerekētanga i waenga i te paahitanga me te korenga, i waenga i te kounga me te mahi anō, i waenga i te hua me te para.
He aha te mea pono o te nekeneke wera?
Ka puta te rerekētanga wera ina puta he rerekētanga pāmahana hei whakawhanui, hei whakawhāiti rānei i ngā wāhanga hanganga o tētahi pūnaha ine, kāore i te ōrite. InaNgā wāhanga o te CMM—te anga, ngā tauine, ngā aratohu, te turanga rānei—ka horapa kore taurite, ka puta he hapa āhuahanga ka arahi ki ngā hapa ine.
He mea huna te raruraru nā te mea kāore e kitea. Kāore e taea te kite i te pikinga pāmahana poutū 9°C puta noa i te tuanui karāhe, engari ka taea e ia te whakaputa i tētahi panonitanga rārangi o te roa kitea i te tere toharite tata ki te 1 μm ia nekehanga Celsius. I roto i te ine taumata nanometa, he tino kino rawa atu tēnā.
Ahakoa te whānuitanga pāmahana whaiti kua whakaritea mō te taiwhanga ine ine—ko te tikanga he 20°C ± 0.5°C—ka taea te whakaputa i te taumahatanga wera nui i roto i ngā hanganga whakarewa hei whakaputa i te nekehanga nui o te ine. He rua te CTE o te maitai i te karāhe. He toru ngā wā teitei ake o te CTE o te konumohe. Ina huri te pāmahana rūma—pērā i roto i tētahi whare tūturu—ka whānui, ka kōpeke ngā wāhanga whakarewa i ngā tere rerekē i te turanga karāhe, ka hanga i te koretake o te ine e uru ana ki ia pānui.
He aha te Granite te Parenga Wera
Ehara i te otinga ngā rauropi whakatikatika pāmahana kaha ake. He turanga e kore e nekeneke i te tuatahi.
Mā te iti rawa o te CTE o te karāhe ka whakaitihia te huringa ā-ahu, ka mau tonu te whanaungatanga ā-ira nui i waenga i ngā toki o te CMM me te wāhanga i inehia. Ko tā mātou karāhe pango ZHHIMG®, me tōna mātotoru o te ≈3100 kg/m³, ka tukuna he pumau pāmahana e nui ake ana i te nuinga o ngā karāhe pango o Ūropi me Amerika. Ko te papatipu wera nui o te turanga karāhe ka mahi hei totohu wera nui, ka whakaiti i ngā piki me ngā heke o te pāmahana me te pupuri i te taiao isothermal mō te rōrahi ine katoa.
Kāore e ranea ngā rauemi anake. He rite tonu te hiranga o te taiao.
Te Hanga i tētahi Taiao Pūmau i te Wera
I ZHHIMG®, kua kawea e mātou te pumau o te wera ki tētahi taumata ahumahi tino teitei. Ko tā mātou awheawhe pāmahana me te haumākū pumau 10,000-mita tapawhā he mea hanga ki runga i tētahi turanga raima tino mārō 1000mm te matotoru. Kei te karapotia te awheawhe e ngā awaawa ārai-wiri, he 500mm te whānui, he 2000mm te hohonu. I roto, ka mahi ngā kerēne puku motuhake hei pupuri i tētahi taiao kore wiri, ā, he pumau hoki te wera.
Engari ka haere tonu mātou. Kei te pupuri mātou i tētahi rūma ma, he pāmahana pumau, he makuku pumau, e whakaata ana i ngā taiao hanga taputapu haurua-ira - he mea hanga motuhake mō te huihuinga wāhanga karāhe. Ehara i te mea ko te pupuri i te pāmahana ki te 20°C anake tēnei. Ko te whakakore i ngā pikinga wera puta noa i ngā wāhanga hanganga nui i te wā tino nui o te hanga: te huihuinga whakamutunga me te tirotiro.
Te Mekameka Ine
Ae, kāore e taea e koe te whakahaere i ngā mea kāore e taea e koe te ine. Koia te take i rite ai tā mātou taiwhanga ine i ngā taputapu ine matatau rawa atu o te ao: ngā ine mata Mahr Tiamana (taumira 0.5 μm), ngā maikoromita me ngā calipers mamati Mitutoyo, ngā taumata hiko WYLER Huiterangi, me ngā interferometer laser Renishaw o Peretānia. Kei ia taputapu ngā tiwhikete whakatikatika mai i te Jinan Institute of Metrology me te Shandong Institute of Metrology—ā, ko ia whakatikatika hua ka taea te whai i ngā hua o te National Institute of Metrology o Haina.
Te Huānga Tangata
Anei tētahi mea kāore i roto i ngā pukapuka ako: ahakoa ngā taputapu pai rawa atu me te taiao tino pumau, kāore e taea te whakakapi i te whakaaro tangata. Ka taea e ā mātou mīhini huri matua, he neke atu i te 30 tau te wheako o ia mīhini huri ringa, te whakatau tika i te maha o ngā maikoroni o te rauemi e tangohia ana e rātou me te whiu kotahi. E kiia ana ēnei e ā mātou kiritaki he "taumata hikoi". Kāore rātou e whai noa i tētahi tukanga; ka rongo rātou i te rauemi, ka rongo i ngā huringa ātete e tohu ana i ngā rerekētanga moroiti o te papatahi.
Mā tēnei porowhita urupare pā—e whakakotahi ana i ngā hanganga o te ao me te māramatanga tangata e kore e taea te whakakapi—ka whakarite kia tutuki i ngā wāhanga karāhe ZHHIMG® katoa, mai i ngā pereti mata ki ngā whāriki hau, ngā paerewa o te ao tino uaua.
Tohutohu Whaihua mō ngā Kaihoko
Mena ka whakahuahia e te kaiwhakarato te kupu "kirihi" me te kore e tohua mēnā he kōhatu keri, he kohuke whakarewa rānei, pātai tika atu—he rerekē te rerekētanga o te utu, te āhuahanga e taea ana te whakatutuki, me te āhua pumau mō te wā roa, ā, me whakauru te rerekētanga ki roto i tētahi pepa whakatakotoranga hangarau. Mō ngā mahi inenga tino tika, tonoa te kiato tuturu, te CTE, me te manawanui papatahi kua tutukihia—kaua ko te ingoa rauemi anake.
Nā te mea i roto i te ao ine taumata-nanomita, ehara te nekenekehanga wera i te raruraru ka whakatauhia e koe mā te utu pūmanawa. He raruraru ka āraihia e koe mā te rauemi tika, te taiao tika, me te hunga tika.
