ʻO kēlā me kēia mea i hoʻolilo i ka manawa ma ka papahele o kahi keʻena hoʻokolohua metrology ua ʻike paha i ke ʻano like: kau nā mīkini kahiko ma luna o nā moena hao i hoʻolei ʻia, nā mea hou ma luna o ka pōhaku ʻeleʻele. ʻAʻole i hana ʻia kēlā hoʻololi no ka mea ʻoi aku ka nani o ka granite ma lalo o nā kukui. Ua hana ʻia ma muli o kahi pilikia physics maikaʻi ʻole - ka hoʻonui ʻana o ka wela.
Hoʻonui a hoʻemi ka hao i hoʻolei ʻia ma kahi o 10-12 x 10⁻⁶ no °C. He mea liʻiliʻi kēlā a hiki i kou kau ʻana ma ka ʻaoʻao o ka granite kūlohelohe, kahi e noho maʻamau ana ma kahi o 5-8 x 10⁻⁶ no °C, a ma kekahi mau granite ʻeleʻele mānoanoa kokoke i 4-5 x 10⁻⁶. Ma kahi kahua ana 1-mika, hiki i kahi loli 1°C i ka mahana ambient ke hoʻoneʻe i kahi ʻili hao i hoʻolei ʻia e kekahi mau microns ma mua o kahi granite like. No ka hoʻomanawanui papahele hale hana, ʻaʻohe mea mālama. No kahi CMM e nānā ana i kahi kahua wafer semiconductor, a i ʻole kahi interferometer laser e paʻa ana i ka sub-micron repeatability, ʻo ia ʻokoʻa ka pāʻani kinipōpō holoʻokoʻa.
He mea nui ka damping e like me ka hoʻonui ʻana
Loaʻa ka hapa nui o ka nānā ʻana i ke kūpaʻa wela, akā ʻo ka damping vibration he mea nui like ia no kekahi mea e hana ana i ka neʻe kiʻekiʻe - nā poʻo koho a kau, nā pae XY, nā kahua ea. He hui kristal ka Granite ma mua o kahi metala homogeneous, no laila ʻaʻole e laha ka haʻalulu mechanical ma o ia mea e like me ka hana ʻana ma o ka hao i hoʻolei ʻia. Hoʻopuehu nā palena palaoa kūloko a omo i ka ikehu ma kahi o ka hoʻouna ʻana iā ia maʻemaʻe. I ka hana maoli, ʻo ia hoʻi hekumu granitenoho wikiwiki ma hope o ka pau ʻana o ka neʻe ʻana o kahi axis mīkini, ʻo ia hoʻi ka manawa noho pōkole a me ka nui o ka throughput ma nā laina nānā a me ka hōʻuluʻulu ʻana.
Aia kekahi mea e pili ana i nā mea e hana ʻia ana i ka wā lōʻihi. Hiki i nā moena hao i hoʻolei ʻia, ʻoiai nā mea i hoʻomaha ʻia i ke kaumaha, ke kolo iki i nā makahiki i ka wā e hoʻolaha hou ʻia ai nā kaumaha o loko. ʻO ka Granite, ua hana mua ʻia ma lalo o ke kaomi kūlohelohe nui i ka manawa geological, ʻaʻohe ona pilikia - ʻaʻole ia e "noho" e like me ke ʻano o ka hoʻolei ʻana.
ʻAʻole like nā granite a pau
ʻO kēia ka ʻāpana e hoʻopio ai i ka nui o nā mea kūʻai. Kūʻai ʻia aku ka Granite ma ke ʻano o ka nui a me ke kala e like me ke kūʻai ʻia ʻana o ka lāʻau ma nā ʻano, akā ʻokoʻa loa ka hana kino ma waena o nā lua pōhaku. ʻO ka pōhaku haʻahaʻa haʻahaʻa, a i ʻole nā mea me nā ʻaʻa ʻike ʻia a me ka palaoa kūlike ʻole, ʻaʻole e paʻa i ka pālahalaha like i ka hala ʻana o ka manawa e like me ka granite ʻeleʻele mānoanoa a maikaʻi i ka pae 2,900-3,100 kg/m³. Hoʻololi ʻia ke kinikini i kekahi manawa e nā mea hoʻolako liʻiliʻi no ka mea ʻoi aku ka maʻalahi o ka mīkini ʻana, akā he pōhaku carbonate metamorphic ke kinikini - palupalu, ʻoi aku ka porous, a ʻoi aku ka liʻiliʻi o ka paʻa o ka dimensiona ma mua o ka granite maoli. No kahi countertop hoʻonaninani, ʻaʻohe mea nui ia. No kahi papa ʻili e kuhikuhi ai kahi probe CMM i nā tausani manawa i ka lā, he mea nui ia, a ʻo ia kekahi o nā ala maʻamau e hoʻololi ai nā mea kūʻai aku me ka ʻike ʻole a hiki i ka hōʻike ʻana o ka calibration drift i nā mahina ma hope.
Ma hea e hōʻike ʻia ai kēia ma ka hana maoli
ʻIke nui ʻia ka hoʻololi ʻana i nā kumu granite i nā lako nānā semiconductor, ka ʻeli PCB a me nā ʻōnaehana AOI, nā mīkini ana ʻekolu-coordinate, nā hoʻonohonoho interferometry laser, a me ka ulu nui ʻana o ka hana ʻana o ka pila a me ka optics precision, kahi i lilo ai ke kūlana sub-micron i koi kumu ma mua o kahi spec luxury. Ke hoʻomau nei ka hoʻomanawanui ma waena o kēia mau ʻoihana - i hoʻokele ʻia e nā node chip liʻiliʻi, nā papa pila lahilahi, a me nā ʻōnaehana laser wikiwiki - ʻo ka hakahaka ma waena o ka hao i hoʻolei ʻia "lawa maikaʻi" a me ka granite paʻa dimensional e lilo wale i mea koʻikoʻi, ʻaʻole emi.
Inā he hoʻokahi mea e lawe ai no nā ʻenekinia e kuhi ana i kahi kahua pololei hou, eia kēia: e noi no nā helu density maoli a me ka hoʻonui ʻana i ka thermal, ʻaʻole wale ka "granite" ma ke ʻano he mea checkbox. ʻO ka ʻokoʻa ma waena o kahi granite dense i koho maikaʻi ʻia a me kahi pani haʻahaʻa haʻahaʻa hiki ke ʻokoʻa ma waena o kahi mīkini e paʻa ana i ka calibration no hoʻokahi ʻumi makahiki a me kahi e pono ai ke hoʻoponopono hou i kēlā me kēia hapaha.
