Ua wehewehe ʻia ke ʻano hana hou e ka paʻakikī ikaika: ka automation wikiwiki, ka pane sensor manawa maoli, a me ke alakaʻi ʻana o ka naʻauao hana i nā lima robotic. Eia naʻe, ma ka puʻuwai o kēia palena ʻenehana aia kahi ʻoiaʻiʻo hoʻokahi, passive, a mau loa: ka Granite Metrology Table. ʻO kēia ʻili kuhikuhi kumu, pinepine he papa ʻili granite precision ʻeleʻele, ke mau nei ke kūlana hope loa e hoʻoholo ʻia ai ka pololei o nā dimensional āpau.
ʻO ka hilinaʻi koʻikoʻi mau ʻana ma lunaNā Mea Hana Ana Granitema nā ʻoihana ʻenehana kiʻekiʻe—mai ka hana ʻana o ka semiconductor a i ka aerospace—ʻaʻole ia he hōʻailona o ke kuʻuna, akā he ʻae hohonu i ka physics mea. Ke koi nā ʻōnaehana i ka pololei a hiki i ka nanometer, pono ke kumu ponoʻī e ʻoi aku ma mua o ka hōʻino ʻia, me ka paʻa e hiki ʻole i kahi ʻōnaehana uila hana ke kope pono.
ʻO ke Kino Paʻa ʻole o ka Granite
ʻO ka pilikia nui i ka metrology ultra-precision ka hoʻokaʻawale ʻana i ke ana ʻana mai ka walaʻau o ke kaiapuni. Hōʻike ʻia kēia walaʻau ma nā ʻano luku ʻelua: ka drift thermal a me ka haʻalulu mechanical.
1. Ke lanakila nei i ka Thermal Drift
ʻO ke kumu nui o ka hewa dimensional i loko o kahi ʻano hana ʻana, ʻo ia ka loli o ka mahana. Ke wela nā mea, hoʻonui lākou; ke hoʻomaʻalili lākou, ʻuʻuku lākou. Hoʻomalu ʻia ke kekelē o kēia loli e ka Coefficient of Thermal Expansion (CTE). Hōʻike nā metala, e like me ke kila a me ka hao i hoʻolei ʻia, i nā CTE kiʻekiʻe. ʻOiai ka loli iki o ka mahana hiki ke hoʻololi i ke kumu kuhikuhi metala e kekahi mau micrometer—he hāʻule koke i ka honua sub-micron.
Loaʻa i ka granite ʻeleʻele kikoʻī kūikawā kahi CTE haʻahaʻa loa, e hoʻolilo ana iā ia i mea paʻa loa. Hōʻoia kēia ʻano maikaʻi e mālama ka Granite Metrology Table i kona pālahalaha a me ka nui i hōʻoia ʻia me ka nānā ʻole i nā loli o ka mahana ambient. Eia kekahi, ʻo ka nui o ka mea e hiki ai iā ia ke omo a hoʻoponopono mālie i ka wela, e hana ana ma ke ʻano he buffer thermal a hoʻemi i ka hopena destabilizing o nā gradients mahana wikiwiki ma kona ʻili.
2. Ka Hoʻohaʻahaʻa ʻana i ka Chaos Mechanical
Loaʻa i kēlā me kēia papahele hale hana ka haʻalulu—mai nā compressors, nā ʻāpana HVAC, nā kapuaʻi, a me nā kaʻa mamao. ʻOiai ʻaʻole ʻike pinepine ʻia e kānaka kēia mau haʻalulu, hiki ke hoʻolei maʻalahi i kahi ana laser koʻikoʻi a hoʻopilikia paha i ke kūlike o kahi ʻāpana kikoʻī.
ʻOi aku ka maikaʻi o ka Granite ma aneʻi ma muli o kona hiki ke hoʻopaʻa i loko. ʻAʻole e like me ka metala, kahi e kani ai a kani paha i ka wā e hahau ʻia ai, hoʻopau koke ka granite i ka ikehu mechanical i loko. Ke kau ʻia kahi mea hana kiʻekiʻe, e like me ka CMM a i ʻole kahi mea hahai laser, ma luna o kahi papa ʻili granite ʻeleʻele pololei, hōʻoia ka granite e hōʻike ana ka ʻikepili i ana ʻia i ke ʻano o ka ʻāpana, ʻaʻole ka walaʻau kinetic o ke kaiapuni. ʻO kēia hui pū ʻana o ka CTE haʻahaʻa a me ka hiki ke hoʻopaʻa kiʻekiʻe e hoʻolilo i ka granite i mea passive wale nō i kūpono no ka lawelawe ʻana ma ke ʻano he kumu no nā ana koi nui loa o ka honua.
ʻO ka Papa Kuhikuhi Granite: Ke Wehewehe ʻana i ka Zero Plane
Ma ke kikowaena o ka nānā ʻana i nā ana ʻana, ʻo ia kaPapa Kuhikuhi Granite, ʻo ia hoʻi ka mea maʻamau e like me kahi papa ʻili granite ʻeleʻele kiʻekiʻe. ʻAʻole kēia he papa hana kaumaha wale nō; ʻo ia ka mokulele zero—ka ʻili kuhikuhi i hōʻoia ʻia a hōʻoia ʻia mai kahi e hoʻomaka ai nā ana linear a me nā angular āpau.
Hana ʻia kēia mau papa i nā kikoʻī koi nui loa, e pili pinepine ana i nā kūlana honua e like me DIN 876, ASME B89, a i ʻole JIS B 7510. ʻO ke ʻano o kahi papa ʻili (e laʻa, Papa 00, Papa 000) e kuhikuhi ana i ka ʻokoʻa pālahalaha i ʻae ʻia ma ka wahi hana holoʻokoʻa. Loaʻa i nā papa kiʻekiʻe loa ka pālahalaha i ana ʻia i nā nanometer wale nō, kahi hana nui i hoʻokō ʻia ma o nā kaʻina hana lapping hope loa.
ʻOi aku ka hana o ka papa ʻili ma mua o ke kākoʻo wale ʻana i kahi ʻāpana:
-
Ke Hoʻokumu nei i ka Datum: Hāʻawi ia i ka laina datum hope loa a i ʻole ka mokulele no nā nānā geometric āpau, e hōʻoiaʻiʻo ana e pili ana nā ana parallelism, squareness, a me straightness i hoʻokahi kiko kuhikuhi i hōʻoia ʻia.
-
Nā Lako Hoʻohui: Hana ka papa ʻaina ma ke ʻano he kumu paʻa no nā Mea Hana Ana Granite kōkua (e like me nā huinaha, nā ʻano like, a me nā poloka V) a me nā mea hana akamai e like me nā pae uila a me nā interferometer laser.
ʻO ke kaiaolaola o nā mea hana ana Granite
ʻO ka papa ʻili ka heleuma, akā ua wehe ʻia kona pono e ka ʻōnaehana o nā Mea Hana Ana Granite i kau ʻia ma luna. ʻAe kēia mau mea kōkua i ka hoʻoili pololei a me ka hōʻoia ʻana o ka ʻoiaʻiʻo geometric.
-
Nā Granite Parallels: Hoʻohana ʻia e hoʻokiʻekiʻe a kākoʻo i nā ʻāpana hana me ka mālama ʻana i ka parallelism e pili ana i ka papa ʻili. ʻO ko lākou kūpaʻa e hōʻoiaʻiʻo ʻaʻole e hoʻopilikia ʻia ke kuhikuhi o ka ʻāpana i ka wā o ke ana ʻana.
-
Nā Poloka V Granite: He mea nui no ke kau ʻana i nā mea cylinder (nā ʻau, nā pine) a me ka hōʻoia ʻana i ka kūlike o ke axis o ka cylinder me ka mokulele kuhikuhi, kahi ʻanuʻu koʻikoʻi no nā ana eccentricity a me ka holo ʻana.
-
Nā Granite Tri Squares a me nā Straight Edges: E like me ka mea i kūkākūkā ʻia ma nā ʻano ʻē aʻe, hoʻoili kēia mau mea hana i ka pālahalaha o ka pā i nā kuhikuhi squareness kūpono a me ka pololei, e ʻae ana i nā loea e hōʻoia i ka perpendicularity o nā neʻe mīkini a i ʻole nā hiʻohiʻona i hōʻuluʻulu ʻia.
ʻO ka hoʻohana mau ʻana i ka granite kiʻekiʻe no kēia mau mea hana ana a pau e hōʻemi ana i ka kūlike ʻole o nā mea a hōʻoia i ka like ʻana o ka hoʻonohonoho ana holoʻokoʻa ma ke ʻano wela a me ke kinetic.
Ka Mana Paʻa o ke Hana Lima a me ka Hiki ke Hahai ʻia
ʻO ka hiki ke hana mau i nā papa granite ʻeleʻele kikoʻī nui a kiʻekiʻe e pono ai kahi hoʻopukapuka kālā ʻaʻole wale i nā mīkini holomua—e like me nā kikowaena hana CNC nui loa a me nā wili kūikawā 6000 mm—akā, i loko o ke kanaka. ʻO ka hana hope loa a koʻikoʻi o ka lapping ʻili e mau ana he akamai hana lima.
Mālama nā mea hana alakaʻi i kahi limahana o nā loea akamai nona nā lima e hiki ke hoʻopā maoli a hoʻoponopono i nā ʻokoʻa ma ka pae sub-micron, kahi mākaukau i hoʻomaʻamaʻa ʻia i nā makahiki he ʻumi. A laila hōʻoia ʻia kēia hana lima e ka kūpaʻa paʻa ʻole i ka hōʻoia maikaʻi. Pono e hōʻoia ʻia nā Mea Hana Ana Granite āpau me ka hoʻohana ʻana i nā lako (e like me nā mea hahai laser a me nā pae uila) nona ka pololei e hiki ke hahai piha ʻia i nā kūlana metrology honua (e laʻa, NIST, NPL, PTB). Hāʻawi kēia kaulahao hoʻomau o ka calibration i ka hilinaʻi piha e pono ai nā ʻoihana kahi e like ai ka pololei me ka palekana, ka pono, a me ka ʻenehana holomua.
ʻO ke akeakamai e alakaʻi ana i kēia ʻoihana he ʻano kūpaʻa paʻa: "ʻAʻole hiki i ka ʻoihana kikoʻī ke koi nui." ʻO ke alo mau o ka Granite Metrology Table maʻalahi a paʻa i loko o nā hale hana ʻenehana kiʻekiʻe loa e hōʻike ana ʻoiai e hana nā mīkini i ka hana ikaika, pono e wehewehe mau ʻia ka ʻoiaʻiʻo geometric e ka mālie a me ka loli ʻole o ka pōhaku.
