He mau mea hana kuhikuhi koʻikoʻi nā papa ʻili Granite i ka metrology pololei. Hana lākou ma ke ʻano he mau ʻili datum mua no ka nānā ʻana, ka hoʻoponopono ʻana, a me ka ʻākoakoa pololei ʻana i nā ʻoihana aerospace, semiconductor, a me nā ʻoihana hana holomua.
Ke hoʻohālikelike ʻia me nā kahua kuhikuhi metala, hāʻawi ka granite i ke kūpaʻa geometric lōʻihi, ka damping vibration, a me ke kūpaʻa thermal, e lilo ia i mea makemake ʻia noana pololei kiʻekiʻenā wahi noho.
ʻEpekema Mea o ka Granite
He pōhaku igneous ka Granite i haku ʻia me ka quartz, feldspar, a me ka mica. Loaʻa kāna hana metrology mai kona microstructure ma mua o ka haku mele like.
Nā waiwai koʻikoʻi:
- Hoʻonui wela: 4–7 × 10⁻⁶ /°C
- Hoʻemi haʻalulu kiʻekiʻe
- ʻAʻohe deformation plastic ma lalo o ke kaumaha maʻamau
- Paʻa lōʻihi o ka ana
ʻAʻole e like me ke kila, ʻaʻole hōʻike ka granite i ka kolo a i ʻole ka hoʻomaha ʻana i ke koʻikoʻi ma lalo o nā kūlana metrology.
Nā Kūlana Honua
Hana ʻia nā papa ʻili Granite ma lalo o nā kūlana honua:
- DIN 876 (Kelemānia)
- ASME B89 (ʻAmelika Hui Pū ʻIa)
- Nā ʻōnaehana maikaʻi ISO 9001
- JIS B7513 (Iapana)
Ho'ākāka kēia mau kūlana i nā māka pālahalaha a me nā koi calibration.
Ke Ana a me ke Kānalua ʻole
He kahua ʻokoʻa geometric ka palahalaha ma mua o hoʻokahi waiwai.
Nā ʻano ana maʻamau:
- ʻO ka interferometry laser
- Nā pae uila
- Nā Autocollimators
ʻO nā kumu kānalua e pili ana i nā gradients thermal, probe repeatability, vibration, a me ka drift instrument.
Nā noi
- Nā Mīkini Ana Hoʻohui (CMM)
- Nā ʻōnaehana nānā semiconductor
- Nā kahua hoʻoponopono CNC
- Nā ʻōnaehana hoʻonohonoho optical
- Nā papa hana metrology laser
Nā nīnau i nīnau pinepine ʻia
No ke aha i hoʻohana ʻia ai ka granite i ka metrology?
Ma muli o kona kūpaʻa, ka damping, a me ka haʻahaʻa o ka hoʻopilikia ʻana o ka wela.
Hiki i ka granite ke hoʻololi i ka lōʻihi o ka manawa?
Ma lalo o nā kūlana maʻamau, ʻaʻole nui ka deformation.
He aha ke kūlana e wehewehe ana i nā papa ʻili?
DIN 876.
Pehea e ana ʻia ai ka palahalaha?
ʻŌnaehana interferometry laser a i ʻole nā ʻōnaehana pae uila.
