Pehea e pili ana i ka pale ʻana o nā ʻāpana granite, pono e hoʻololi pinepine ʻia?

Hoʻohana nui ʻia nā ʻāpana Granite i ka ʻoihana hana e like me ka hāʻawi ʻana i ke kūpaʻa kiʻekiʻe a me ka pololei. ʻO nā mīkini ana ʻekolu-coordinate (CMM) kekahi o nā mea hana hana e hoʻohana ana i nā ʻāpana granite. ʻO ka hoʻohana ʻana i nā ʻāpana granite i nā CMM e hōʻoiaʻiʻo i nā ana kūpono ma muli o ko lākou mau waiwai kūlohelohe e like me ke kiʻekiʻe ʻoʻoleʻa, rigidity, a me ke kūpaʻa wela. Hana kēia mau waiwai i nā ʻāpana granite i kūpono no ke ana ʻana i nā mīkini e koi ana i ka pololei kiʻekiʻe a me nā ana kikoʻī.

ʻO kekahi o nā pono koʻikoʻi o ka hoʻohana ʻana i nā ʻāpana granite i CMM ʻo ko lākou pale ʻana. ʻO ka Granite he pōhaku maoli paʻa a paʻa loa a ʻike nui ʻia no kona ikaika a kūʻē i ka ʻaʻahu. Hiki i nā ʻāpana Granite i hoʻohana ʻia i nā CMM ke kū i nā kūlana hana koʻikoʻi, me ka vibrations a me ke kaomi, me ka ʻole o ka hōʻike ʻana i nā hōʻailona o ka ʻaʻahu a i ʻole deformation. ʻO ke kūpaʻa ʻana o nā mea granite e hōʻoiaʻiʻo ʻaʻole lākou e koi i nā pani maʻamau, ʻo ia ka mea e hōʻemi i nā kumukūʻai mālama a hoʻonui i ka manawa o ka mīkini.

Eia kekahi, he haʻahaʻa ka mālama ʻana i nā ʻāpana granite. Pono lākou i ka mālama liʻiliʻi, a me ka mālama pono a me ka hoʻomaʻemaʻe maʻamau, hiki iā lākou ke mālama i ko lākou pololei a me ka pololei no nā makahiki. ʻO ka hoʻohana ʻana i nā ʻāpana granite i nā CMM e hōʻoiaʻiʻo i ka mālama ʻana o ka mīkini i kona pololei, e alakaʻi ana i ka liʻiliʻi o nā hewa ana a me ka hoʻomaikaʻi ʻana i nā hopena hou.

Ma waho aʻe o ka pale ʻana a me ke kūpaʻa maikaʻi loa, hāʻawi nā ʻāpana granite i ke kūpaʻa kūlohelohe i ka deformation i hoʻokumu ʻia e ka fluctuations wela. ʻO ka haʻahaʻa haʻahaʻa o ka hoʻonui wela (CTE) o ka granite e hōʻoia i ka pololei o nā ana e hoʻomau like ʻole me ka nānā ʻole o ka mahana o ka hana. Hoʻohana ka CTE haʻahaʻa i ka granite no ka hoʻohana ʻana i nā CMM e koi ana i nā kaʻina ana pololei a me ke kūpaʻa maikaʻi loa.

I ka hopena, ʻo ka hoʻohana ʻana i nā ʻāpana granite i nā CMM e hōʻoiaʻiʻo i ka pololei kiʻekiʻe a me ke kūpaʻa, a he liʻiliʻi ka pono o ke pani. ʻO ke kūpaʻa ʻaʻahu, ka mālama haʻahaʻa, a me ke kūpaʻa kūlohelohe i ka deformation i hoʻokumu ʻia e ka piʻi ʻana o ka mahana e hana i nā mea granite kūpono no ka hoʻohana ʻana i nā CMM, a me nā ʻoihana ʻē aʻe e koi ana i nā kaʻina hana kiʻekiʻe. ʻO nā pōmaikaʻi o nā ʻāpana granite i loko o nā CMM e pili ana i ka hana kiʻekiʻe, hoʻomaikaʻi i ka maikaʻi o ka maikaʻi, a me ka hoʻohaʻahaʻa ʻana i ka manawa, e alakaʻi ana i ka hoʻomaikaʻi ʻana i ka huahana a me ka loaʻa kālā.
