Ua hoʻopukapuka kālā ʻoe i kahi mīkini ana hoʻonohonoho kiʻekiʻe loa. Ua hoʻoponopono ʻia ka polokalamu. Ua hōʻoia ʻia nā probes. Akā naʻe, ke neʻe nei kāu mau ana. ʻAʻole nui loa—he micron wale nō ma ʻaneʻi, hapalua micron ma laila. Akā i loko o ke ao o ka metrology ultra-precision, ʻo kēlā neʻe ʻana ka ʻokoʻa ma waena o ka hala a me ka hāʻule ʻana, ma waena o ka maikaʻi a me ka hana hou ʻana, ma waena o ka loaʻa kālā a me ka ʻōpala.
He aha maoli ka Thermal Drift?
Hana ʻia ka ʻauʻau wela i ka wā e hoʻonui ai nā loli o ka mahana i nā ʻāpana kūkulu o kahi ʻōnaehana ana a i ʻole e ʻuʻuku like ʻole.Nā ʻāpana o CMM—ke kiʻikuhi, nā unahi, nā alakaʻi, a i ʻole ke kumu—e hoʻonui like ʻole, hoʻolauna lākou i nā distortions geometric e alakaʻi ai i nā hewa ana.
He mea huna ka pilikia no ka mea, ʻaʻole ia e ʻike maka ʻia. ʻAʻole hiki iā ʻoe ke ʻike i ka gradient mahana kū pololei 9°C ma luna o kahi lintel granite, akā hiki iā ia ke hana i kahi loli linear o ka lōʻihi i ʻike ʻia ma kahi wikiwiki e awelika ana ma kahi o 1 μm no ke kēkelē Celsius. Ma ka metrology pae nanometer, he mea weliweli kēlā.
ʻOiai ka pae mahana haiki i kauoha ʻia o kahi keʻena hoʻokolohua metrology—maʻamau 20°C ± 0.5°C—hiki ke hoʻoulu i ka lawa ʻana o ke kaumaha wela i loko o nā hale metala e hana ai i ka neʻe nui ʻana o ke ana. Loaʻa i ke kila kahi CTE ma kahi o ʻelua manawa o ka granite. Loaʻa i ka Aluminum kahi CTE ma kahi o ʻekolu manawa kiʻekiʻe. Ke hoʻololi ka mahana o ka lumi—e like me ia ma kekahi hale hana maoli—hoʻonui a hoʻemi nā ʻāpana metala ma nā wikiwiki like ʻole ma mua o ke kumu granite, e hana ana i ka maopopo ʻole o ke ana i hoʻomoʻa ʻia i loko o kēlā me kēia heluhelu.
No ke aha ʻo Granite ka pale wela
ʻAʻole ʻoi aku ka ikaika o nā algorithms hoʻoponopono mahana. He kahua ia e neʻe ʻole ai ma kahi mua.
Hoʻemi ka CTE haʻahaʻa loa o Granite i ka loli dimensional, e mālama ana i ka pilina geometric koʻikoʻi ma waena o nā koʻi o ka CMM a me ka ʻāpana i ana ʻia. ʻO kā mākou granite ʻeleʻele ZHHIMG®, me kona density o ≈3100 kg/m³, hāʻawi i ke kūpaʻa thermal e ʻoi aku ma mua o ka hapa nui o nā granite ʻeleʻele ʻEulopa a me ʻAmelika. ʻO ka nui o ka thermal o kahi kumu granite e hana ma ke ʻano he poho wela passive nui, e hoʻomāmā ana i nā loli o ka mahana a mālama i kahi ʻano isothermal no ka nui o ke ana holoʻokoʻa.
Akā, ʻaʻole lawa ka mea wale nō. He mea nui nō hoʻi ke kaiapuni.
Ke ʻenekinia ʻana i kahi kaiapuni paʻa wela
Ma ZHHIMG®, ua lawe mākou i ke kūpaʻa wela i kahi ʻoihana kiʻekiʻe loa. Ua kūkulu ʻia kā mākou hale hana mahana a me ka haʻahaʻa mau he 10,000-mika kuea ma luna o kahi kahua sima paʻakikī loa he 1000mm ka mānoanoa. Ua hoʻopuni ʻia ka hale hana e nā ʻauwaha anti-vibration e ana ana i 500mm ka laulā a me 2000mm ka hohonu. I loko, hana nā crane leo ʻole kūikawā e mālama i kahi kaiapuni ʻaʻohe haʻalulu a paʻa i ka wela.
Akā, e hele hou aku mākou. Mālama mākou i kahi lumi maʻemaʻe i hoʻolaʻa ʻia me ka mahana mau, ka haʻahaʻa mau e hoʻohālike ana i nā wahi hana hana semiconductor—i hoʻolālā kūikawā ʻia no ka hōʻuluʻulu ʻana o nā ʻāpana granite. ʻAʻole kēia e pili ana i ka mālama ʻana i ka mahana ma 20°C. E pili ana i ka hoʻopau ʻana i nā gradients thermal ma waena o nā ʻāpana kūkulu nui i ka wā koʻikoʻi loa o ka hana ʻana: ka hōʻuluʻulu hope loa a me ka nānā ʻana.
Ke Kaulahao Ana
ʻOiaʻiʻo, ʻaʻole hiki iā ʻoe ke kāohi i nā mea hiki ʻole iā ʻoe ke ana. ʻO ia ke kumu i lako ai kā mākou keʻena hoʻokolohua metrology me nā mea hana ana holomua loa o ka honua: nā ana kelepona Mahr Kelemania (0.5 μm hoʻonā), nā micrometer Mitutoyo a me nā calipers kikohoʻe, nā pae uila Swiss WYLER, a me nā interferometer laser Renishaw Pelekane. Loaʻa i kēlā me kēia mea hana nā palapala hōʻoia calibration mai ka Jinan Institute of Metrology a me ka Shandong Institute of Metrology—a hiki ke hoʻihoʻi ʻia kēlā me kēia calibration huahana i ka National Institute of Metrology of China.
ʻO ke Kumu Kanaka
Eia kekahi mea a nā puke aʻo i haʻi ʻole aku ai iā ʻoe: ʻoiai nā lako maikaʻi loa a me ke kaiapuni paʻa loa, ʻaʻole hiki ke pani i ka noʻonoʻo kanaka. Hiki i kā mākou mau wili akamai, me kēlā me kēia me ka ʻoi aku o 30 mau makahiki o ka ʻike lima-lapping, ke hoʻoholo pololei i ka nui o nā microns o nā mea a lākou e wehe nei me hoʻokahi hahau. Ua kapa ʻia lākou e kā mākou mea kūʻai aku he "walking electronic levels". ʻAʻole lākou e hahai wale i kahi kaʻina hana; manaʻo lākou i ka mea, e ʻike ana i nā loli kū'ē e hōʻike ana i nā ʻokoʻa microscopic i ka flatness.
ʻO kēia loop feedback tactile—e hoʻohui ana i nā ʻōnaehana papa honua me ka naʻauao kanaka hiki ʻole ke hoʻololi—e hōʻoiaʻiʻo ana e hoʻokō kēlā me kēia ʻāpana granite ZHHIMG®, mai nā papa ʻili a hiki i nā bearings ea, i nā kūlana honua koʻikoʻi loa.
ʻŌlelo Aʻo Kūpono no nā Mea Kūʻai
Inā ʻōlelo ka mea hoʻolako i ka "granite" me ka ʻole o ka wehewehe ʻana inā he pōhaku i kālai ʻia a i ʻole he minelala i hoʻolei ʻia, e nīnau pololei—ua lawa ka ʻokoʻa o ke kumukūʻai, ke ʻano geometry hiki ke hoʻokō ʻia, a me ke ʻano paʻa lōʻihi e pono ai ke ʻokoʻa i loko o kekahi pepa kikoʻī loea. No ka hana metrology kiʻekiʻe, e noi i ka density maoli, CTE, a me ke ahonui flatness i loaʻa—ʻaʻole wale ka inoa mea.
No ka mea, i loko o ke ao o ke ana ʻana o ka pae nanometer, ʻaʻole ka thermal drift kahi pilikia āu e hoʻoponopono ai me ka uku polokalamu. He pilikia ia āu e pale ai me nā mea kūpono, ke kaiapuni kūpono, a me nā kānaka kūpono.
