ʻO ka ʻekolu-coordinate, ka mea i kapa ʻia ʻo ke ana, he mīkini no ke ana ʻana i ka pololei, i kapa ʻia ʻo CMM.He mea ana pono kūpono i kūkulu ʻia i nā makahiki 1960.Ua puka mai ma muli o ke kiʻekiʻe o ka hana ʻana i nā mīkini mīkini a me nā mīkini mīkini CNC, a me ka pono o nā mea ana wikiwiki a hilinaʻi no ka hana ʻana i nā ʻāpana ʻano paʻakikī.

I kēia manawa, ua hoʻohana nui ʻia ke ana ʻekolu-coordinate i nā ʻoihana like ʻole e like me ka hana mīkini, ʻoihana kaʻa, ʻoihana uila, ʻoihana aerospace, a me nā mea ʻē aʻe, a ua lilo ia i mea pono nui e ana i nā lako hana no ka nānā ʻana i ka ʻoihana hou a me ka mana maikaʻi.No kā mākou mau ana maʻamau maʻamau ʻole, ʻo ke ana ʻekolu-coordinate kahi mea hoʻāʻo pono ʻole.Ma hope o ka loaʻa ʻana o nā kiʻi huahana a ka mea kūʻai aku a hoʻolālā i ka hoʻolālā gage e kū ana i nā koi kūpono o ka huahana a ʻoluʻolu ka mea kūʻai aku, pono ia.E hoʻomaka i nā ʻanuʻu hana i ka pae hope, a laila pono mākou e hoʻohana i kā mākou ana ʻekolu-coordinate, no ka mea, ʻoi aku ka kiʻekiʻe o ka pololei o ka hāmeʻa ponoʻī, no laila e hoʻohana iā ia e hoʻāʻo i ka pololei o kēlā me kēia ʻāpana o kā mākou ana, no ka mea ʻoi aku ka nui. hōʻoia i ka pololei o kā mākou mau mea hana nānā.Eia kekahi laʻana, aia kekahi kūlana o ka gage, palahalaha a me kāna ʻaoʻao i kekahi mau ʻāpana o ke kaʻa.Hiki iā mākou ke loaʻa i ka nui maoli ma ka ʻike ʻana i ke ana coordinate
