I loko o ke ao hana ponoʻī o ka ʻenekinia ultra-precision, kahi e hoʻokele ai nā ʻōnaehana hahai laser paʻakikī a me nā algorithms paʻakikī i ka kaohi neʻe, me he mea lā kūʻē i ka manaʻo maʻamau e hilinaʻi mau ana ka pololei geometric hope loa i nā mea hana e hoʻi ana i nā lā mua o ka metrology. Eia naʻe, i ka wā e hoʻoikaika hohonu ai ka ʻoihana i nā ʻāpana sub-micron a me nanometer, ke kuleana kumu o nā mea hana granite precision—ʻo ia hoʻi ka granite straight ruler me ka Grade 00 precision, ka granite square, a me kagranite tri square—ʻaʻole i hoʻomau wale ʻia, akā ua hoʻonui ʻia. ʻO kēia mau mea hana paʻa a passive nā kiko kuhikuhi paʻa ʻole e hōʻoia i ka hana o nā ʻōnaehana dynamic holomua loa.
ʻO ke kumu o kēia mau mea hana kuhikuhi granite mai kahi loina kino kumu: ke kūpaʻa wela a me ka mechanical. Pono kēlā me kēia mīkini i hoʻolālā ʻia no ka pololei kiʻekiʻe e hōʻoia i ka ʻoiaʻiʻo, pololei, a kū pololei hoʻi o kāna mau mokulele ana a me ka huakaʻi linear. Ke koi nei ka hana hou i ke kūpaʻa dimensional i hoʻopilikia ʻole ʻia e nā loli o ka mahana a i ʻole nā haʻalulu o waho, ʻo nā mea e like me ke kila a i ʻole ka hao i hoʻolei ʻia—me ko lākou coefficient kiʻekiʻe o ka hoʻonui ʻana o ka thermal (CTE) a me ka hiki ke damping haʻahaʻa—e hāʻule i ka hoʻāʻo.
ʻO ka Granite, ma ka ʻaoʻao ʻē aʻe, hāʻawi ia i kahi kūpono no ke kūpaʻa. ʻO kona CTE haʻahaʻa ʻo ia hoʻi, ʻo nā loli o ka mahana e hoʻoulu ai i ka liʻiliʻi o ka dimensional drift, e lilo ia i mea kūpono no ka wehewehe ʻana i kahi mokulele kuhikuhi e mau ana ka wānana. Eia kekahi, ʻo kona hiki ke damping kiʻekiʻe kūlohelohe e omo koke i nā haʻalulu, e pale ana i ke kamaʻilio a me ke kani ʻana e hoʻolaha ʻia e nā mea hana metala, he mea koʻikoʻi ia i nā keʻena metrology a me nā wahi hōʻuluʻulu kahi e paʻakikī mau ai ka walaʻau ambient.
Ke Kumu o ke Linearity: Granite Straight Ruler me ka Grade 00 Precision
ʻO ke ana ʻana o ka pololei ke kihi o ka metrology dimensional. Hilinaʻi kēlā me kēia alakaʻi linear, ka ea ea, a me ke axis CMM i kahi ala pololei hiki ke hōʻoia ʻia o ka neʻe ʻana. No nā noi koi maoli, ʻo ka lula pololei granite me ka pololei Grade 00 e lilo i mana piha.
ʻO ke koho ʻana o ka Papa 00 (a i ʻole ka Papa Master like) e hōʻike ana i ka pae kiʻekiʻe loa o ka pololei i hiki ke loaʻa ma waho o nā keʻena hoʻokolohua kūlana aupuni. Pono kēia pae o ka pololei e ana ʻia ka ʻokoʻa pololei ma ka lihi hana holoʻokoʻa o ka lula ma nā hapa o ka micron. ʻO ka hoʻokō ʻana i kēia pae o ka kūpaʻa geometric ʻaʻole wale nō ka mea kūpono akā ʻo ke kaʻina hana i kāohi pono ʻia.
Pono ke kaʻina hana e pili i nā kikoʻī honua koʻikoʻi, e like me nā kūlana DIN, JIS, ASME, a i ʻole GB. Kuhikuhi kēia mau kūlana honua i nā kaʻina hana hoʻāʻo, nā kūlana kaiapuni, a me nā ʻae ʻia. No nā mea hana e lawelawe ana i nā mea kūʻai aku honua—mai nā ʻoihana semiconductor Kepanī a hiki i nā mea hana mīkini Kelemania—ʻo ka hiki ke hōʻoia i kahi lula pololei granite e kūʻē i nā kūlana he nui i ka manawa like he hōʻailona ia o ka ʻike loea a me ka paʻa o ka ʻōnaehana maikaʻi. He maʻalahi ka hana a kēia lula: e hāʻawi i kahi laina passive, hiki ʻole ke hoʻololi ʻia e hiki ai ke hoʻopaʻa ʻia a uku ʻia ka hewa pololei o kahi axis mīkini dynamic.
Ke Wehewehe ʻana i ka Perpendicularity: ʻO ka Granite Square a me ka Granite Tri Square
ʻOiai ʻo ka pololei e kuhikuhi ana i ka maikaʻi o ka neʻe linear, ʻo ka perpendicularity (a i ʻole squareness) e kuhikuhi ana i ke geometry hana o ka mīkini. Pono ka huina o nā axis neʻe (e like me nā axis X a me Y, a i ʻole ka axis Z e pili ana i ka mokulele kumu) he 90° pololei. ʻO kēlā me kēia ʻokoʻa ma ʻaneʻi, i ʻike ʻia ʻo ka squareness error, e unuhi pololei ʻia i loko o ka positional error, e hoʻonui ana i ka paʻakikī o ka hoʻokō ʻana i ke kau ʻana o nā hiʻohiʻona pololei.
ʻO ka huinahā granite a me ka huinahā tri granite nā mea hana nui i hoʻohana ʻia e hōʻoia i kēia kihi kumu.

Hoʻohana pinepine ʻia ka huinahā granite e hōʻoia i ke kūlike o nā koʻi mīkini e pili ana i kahi papa ʻili kuhikuhi a i ʻole e hōʻoia i ka perpendicularity o nā ʻāpana i ka wā o ka ʻākoakoa ʻana. ʻO kona geometry L-shaped ikaika e hōʻoiaʻiʻo ana e mālama ʻia nā ʻaoʻao hana ʻelua ma kahi kihi 90° i hōʻoia ʻia.

Hāʻawi ka granite tri square (a i ʻole master square) i kahi hoʻonohonoho geometric ʻekolu-ʻaoʻao kū hoʻokahi, e ʻae ana i kahi nānā piha o ke geometry cubic i loko o kahi mōlina mīkini. He mea pono loa kēia hoʻonohonoho no ka hoʻokumu ʻana i nā palena cubic o nā CMM a i ʻole nā mōlina mīkini nui, e hōʻoia ana he huinahā nā mokulele āpau kekahi i kekahi a i ke kumu.
E like me ke aliʻi pololei, pono kēia mau huinahā e hoʻokō i ka palapala hōʻoia Papa 00, e koi ana i nā kihi e kūlike i loko o nā arc-kekona. He hana kēia e hilinaʻi ana i ke kūpaʻa kiʻekiʻe o ka mea granite a me ke akamai hiki ʻole ke hoʻololi ʻia o nā mea hana lima e hoʻohana ana i nā makahiki he ʻumi o ka ʻike i ke kaʻina hana lima-lapping e hoʻokō ai i ka geometry ʻili hope loa a kīnā ʻole.
ʻO ke Kaiaola Hana Lima: ʻOi aku ma mua o ka Pōhaku wale nō
ʻAʻole wale ka mana o kēia mau mea hana metrology granite i ka mea hana, akā, i loko o ka ʻōnaehana holoʻokoʻa e kākoʻo ana i kā lākou hōʻoia a me ka hana ʻana. Hoʻomaopopo nā ʻoihana e alakaʻi nei i kēia kahua he moʻomeheu ka pololei, ʻaʻole wale kahi kikoʻī huahana.
Hoʻomaka ia me nā mea hana lima akamai. Ma nā hale hana kūikawā a kāohi nui ʻia, loaʻa pinepine i nā haku wili pololei he kanakolu a ʻoi aku paha mau makahiki o ka ʻike. He akamai kēia poʻe i ka hoʻohana ʻana i nā papa lapping kūikawā a me nā hui abrasive e hoʻoponopono lima i nā hemahema microscopic, e hana pinepine ana i nā hoʻomanawanui e hiki ai i ko lākou mau lima ke ʻike maikaʻi ma mua o ka hapa nui o nā mea ʻike uila. ʻO kā lākou ʻike i hōʻiliʻili ʻia e hiki ai iā lākou ke hoʻokō i nā hoʻopau ʻili e hoʻokuke i nā palena o ka pālahalaha a me ka pololei, i kekahi manawa e hiki ana i lalo i ka pālākiō nanometer no ka hoʻopau maʻalahi loa e pono ai nā noi ea. ʻO kēia akamai kanaka ke kumu o ka hoʻokaʻawale ʻana i ka hoʻokō ʻana i nā koi koʻikoʻi o ka Papa 00.
Ua nānā pono ʻia a hōʻoia ʻia kēia hana lima. Pono ke kahua hana e paʻa loa, e hōʻike ana i nā lumi maʻemaʻe i kāohi ʻia e ke aniau, nā kahua sima anti-vibration, a me nā lako ana kūikawā e like me nā interferometer laser a me nā pae uila i hoʻoponopono mau ʻia a hiki ke hahai ʻia i nā keʻena hoʻokolohua kūlana aupuni. Hōʻoia kēia kūpaʻa e mau ana ke ʻano geometry i hōʻoia ʻia o ka ʻāpana mai ka manawa e haʻalele ai i ka papahele hale hana.
ʻO ka hilinaʻi ʻana i kēia mau mea hana kahiko akā i hoʻomaikaʻi ʻia e hōʻike ana i kahi ʻoiaʻiʻo hohonu i ka ʻenekinia ultra-precision: ʻo ka ʻimi ʻana i ka wikiwiki dynamic a me ka paʻakikī computational e pono e hoʻopaʻa mau ʻia i kahi ʻoiaʻiʻo geometric static a hiki ke hōʻoia ʻia. ʻO ka lula pololei granite me ka Grade 00 precision, ka granite square, a me ka granite tri square ʻaʻole ia he mau koena o ka wā i hala; ʻo lākou nā kūlana pono a paʻa ʻole e hōʻoiaʻiʻo ana i ka pono geometric o ka wā e hiki mai ana. Ma ka mālama ʻana i ka pili pono loa i nā kūlana DIN, JIS, ASME, a me GB, hōʻoia nā mea hana loea e noho mau ana kahi ʻāpana pōhaku maʻamau i mea hana akamai loa no ka wehewehe ʻana i ka ʻoiaʻiʻo dimensional.
