He aha nā noʻonoʻo loea no ka CMM e koho ai i ka granite ma ke ʻano he spindle a me ka mea hana?

I ke ao o ka kaohi maikaʻi a me ke ana pololei ʻana, ʻo ka Coordinate Measuring Machine (CMM) kekahi o nā mea hana koʻikoʻi loa. Hoʻohana ʻia kēia mea ana holomua i nā ʻoihana like ʻole, me ka aerospace, automotive, medical, a me ka hana ʻana, e hōʻoia i ka pololei i ke ana ʻana o ka huahana, ka kaohi maikaʻi, a me ka nānā ʻana. ʻAʻole hilinaʻi wale ka pololei o ka CMM i ka hoʻolālā a me ka ʻenehana o ka mīkini akā i ka maikaʻi o nā mea i hoʻohana ʻia i kona kūkulu ʻana. ʻO kekahi o ia mau mea koʻikoʻi i hoʻohana ʻia ma CMM ʻo ia ka granite.

ʻO Granite kekahi o nā mea maʻamau i hoʻohana ʻia i ke kūkulu ʻana o nā CMM ma muli o kona mau waiwai kūikawā e lilo ai ia i mea kūpono no nā moena mīkini, spindle, a me nā ʻāpana hana. He pōhaku kūlohelohe ʻo Granite i paʻa loa, paʻakikī, a paʻa. ʻO kēia mau waiwai e lilo ai ia i mea kūpono no ka hāʻawi ʻana i ka damping maikaʻi loa a me ke kūpaʻa wela ma CMM.

ʻAʻole wale ke koho ʻana o ka granite ma ke ʻano he mea nui no CMM he hoʻoholo wale nō ia. Ua koho ʻia ka mea ma muli o kona mau waiwai mechanical maikaʻi loa, me ke kiʻekiʻe o ka paʻakikī, ke kiʻekiʻe o ka modulus o ka elasticity, ka hoʻonui wela haʻahaʻa, a me ke kiʻekiʻe o ka omo ʻana o ka haʻalulu, no laila e hōʻoiaʻiʻo ana i kahi kiʻekiʻe o ka pololei a me ka hana hou ʻana i nā ana.

He haʻahaʻa ka coefficient o ka hoʻonui wela o ka Granite, ʻo ia hoʻi hiki iā ia ke kū i nā loli wela kiʻekiʻe a mālama i kona kūpaʻa dimensional. He mea koʻikoʻi kēia waiwai i loko o kahi CMM no ka mea pono ka mīkini e mālama i kona pālahalaha a me ke kūpaʻa ʻoiai ke hōʻike ʻia i nā loli mahana. ʻO ke kūpaʻa wela o ka granite, i hui pū ʻia me kona hiki ke omo i nā haʻalulu a hōʻemi i ka walaʻau, e lilo ia i mea kūpono no ka papa hana, ka spindle, a me ke kumu.

Eia kekahi, ʻaʻole hoʻi he magnetic ka granite a he kūpaʻa maikaʻi kona i ka pala, e lilo ia i koho maikaʻi loa, ʻoiai hoʻi i ka ʻoihana hana kahi i maʻamau ai ke ana ʻana o nā ʻāpana metala. ʻO ka waiwai non-magnetic o ka granite e hōʻoiaʻiʻo ana ʻaʻole ia e hoʻopilikia i nā ana i hana ʻia me ka hoʻohana ʻana i nā probes uila, kahi e hiki ai ke hana i nā hewa i nā heluhelu.

Eia kekahi, he maʻalahi ka granite e hoʻomaʻemaʻe a mālama, e lilo ia i mea koho hilinaʻi. He lōʻihi hoʻi a paʻa, ʻo ia hoʻi, hāʻawi ia i kahi ola mīkini lōʻihi, e hōʻemi ana i ke kumukūʻai o ka hoʻololi a me ka mālama ʻana.

I ka hōʻuluʻulu manaʻo, ʻo ke koho ʻana o ka granite ma ke ʻano he spindle a me ka mea hana no CMM e pili ana i kona mau waiwai mechanical a me thermal maikaʻi loa. Hiki i kēia mau waiwai i ka CMM ke hāʻawi i nā ana pololei a pololei, mālama i ke kūpaʻa dimensional, a hoʻopili i nā haʻalulu a me ka walaʻau, a me nā pono ʻē aʻe. ʻO ka hana kiʻekiʻe a me ke ola lōʻihi o kahi CMM i kūkulu ʻia me nā ʻāpana granite e lilo ia i mea hoʻopukapuka maikaʻi loa no kekahi ʻoihana a hui paha e pono ai ke ana kiʻekiʻe a me ka kaohi maikaʻi.
