Hoʻohana nui ʻia nā mīkini ana coordinate (CMMs) i nā ʻoihana e like me nā mīkini, uila, mea kani, a me nā plastics. He ala maikaʻi nā CMM no ke ana ʻana a loaʻa i ka ʻikepili dimensional no ka mea hiki iā lākou ke pani i nā mea hana ana i ka ʻili a me nā ana hoʻohui pipiʻi, e hōʻemi ana i ka manawa i koi ʻia no nā hana ana paʻakikī mai nā hola a i nā minuke-he mea hiki ʻole ke loaʻa me nā mea hana ʻē aʻe.
Nā mea e pili ana i nā mīkini ana hoʻonohonoho: nā mea e pili ana i ka coaxiality i nā ana CMM. Ma ka pae aupuni, ua wehewehe ʻia ka ʻāpana hoʻomanawanui coaxiality no nā CMM ma ke ʻano he wahi i loko o ka ʻili cylindrical me ke anawaena hoʻomanawanui o t a me ka coaxial me ka axis datum o CMM. Loaʻa iā ia ʻekolu mau mea mana: 1) axis-to-axis; 2) axis-to-common axis; a me 3) waena-i-waena. Nā mea e pili ana i ka Coaxiality ma 2.5-Dimensional Ana: ʻO nā kumu nui e pili ana i ka coaxiality ma nā ana 2.5-dimensional, ʻo ia ke kūlana waena a me ke kuhikuhi axis o ka mea i ana ʻia a me ka element datum, ʻoi aku ka nui o ke kuhikuhi axis. No ka laʻana, i ke ana ʻana i ʻelua pōʻai ʻāpana ʻāpana ma kahi puʻupuʻu datum, hoʻohana ʻia ka laina hoʻohui e like me ke axis datum.
Ua ana pū ʻia nā pōʻai keʻa ʻelua ma ka cylinder i ana ʻia, kūkulu ʻia kahi laina pololei, a laila helu ʻia ka coaxiality. Ke manaʻo nei he 10 mm ka mamao ma waena o nā ʻāpana ukana ʻelua ma ka datum, a ʻo ka mamao ma waena o ka ʻili ukana datum a me ka pauku kea o ka cylinder i ana ʻia he 100 mm, inā ʻo ke kūlana waena o ka pōʻai keʻa ʻelua o ka datum he 5um ke ana ʻana me ke kikowaena o ka ʻāpana keʻa o ka pōʻai, a laila ua lōʻihi ka axis 50um i ke ana ʻana. keu (5umx100:10). I kēia manawa, ʻoiai inā he coaxial ka cylinder i ana ʻia me ka datum, ʻo nā hopena o nā ana ʻelua-dimensional a me 2.5-dimensional e loaʻa mau ana ka hewa o 100um (ʻo ka helu hoʻomanawanui degere like ke anawaena, a ʻo 50um ka radius).
