ʻO nā ʻōnaehana neʻe laina laina - i loaʻa i kahi kumu a hale paha, kahi ʻōnaehana alakaʻi, a me kahi mīkini hoʻokele - loaʻa i nā ʻano hoʻolālā a me nā hoʻonohonoho like ʻole e kūpono i nā noi āpau.A no ka ʻokoʻa ʻana o kā lākou hoʻolālā, hoʻokaʻawale pinepine ʻia lākou e like me ke kumu hana a me nā loina hana.Ka hihia: ʻO ka huaʻōlelo "actuator" e pili ana i kahi ʻōnaehana laina laina me kahi hale alumini e hoʻopili ai i ke alakaʻi a me nā mīkini hoʻokele;ʻO nā ʻōnaehana i kapa ʻia ʻo "nā papa," a i ʻole "nā papa XY," i hoʻolālā pinepine ʻia me kahi baseplate i kau ʻia ai ke alakaʻi a me nā mea hoʻokele;a ʻo ka "pae laina" a i ʻole "pae unuhi laina" e pili ana i kahi ʻōnaehana e like me ke kūkulu ʻana me ka papa laina akā i hoʻolālā ʻia e hōʻemi i nā hewa i ka hoʻonohonoho ʻana a me ka huakaʻi.
Hiki i nā ʻōnaehana laina laina ke hōʻike i ʻekolu ʻano hewa: nā hewa laina, nā hewa angular, a me nā hewa planar.
ʻO nā hewa laina he mau hewa i ka pololei o ka hoʻonohonoho ʻana a me ka hoʻihoʻi hou ʻana, e pili ana i ka hiki ʻana o ka ʻōnaehana i ke kūlana i makemake ʻia.
ʻO nā hewa angular - i kapa pinepine ʻia ʻo ka roll, pitch, a me ka yaw - pili i ka hoʻololi ʻana e pili ana i nā koʻi X, Y, a me Z.Hiki i nā hewa angular ke alakaʻi i nā hewa ʻo Abbé, ʻo ia nā hewa angular i hoʻonui ʻia e ka mamao, e like me ka mamao ma waena o ke alakaʻi laina (ke kumu o ka hewa angular) a me ke kiko mea hana o kahi mea ana.He mea nui e hoʻomaopopo i ka loaʻa ʻana o nā hewa angular inā ʻaʻole i neʻe ke kahua, no laila hiki ke loaʻa ka hopena maikaʻi ʻole i nā hana static e like me ke ana ʻana a i ʻole ka nānā ʻana.
Loaʻa nā hewa planar ma nā ʻaoʻao ʻelua - nā deviations i ka huakaʻi ma ka mokulele i kapa ʻia ʻo straightness, a me nā deviations i ka huakaʻi ma ka plane vertical, i kapa ʻia ʻo flatness.
ʻOiai ʻaʻohe kānāwai a i ʻole nā alakaʻi koʻikoʻi no ke ʻano o kahi pae laina, ʻike nui ʻia lākou ʻo ia ka ʻāpana pololei loa o nā ʻōnaehana laina laina.Ke kapa ʻia kahi ʻōnaehana ma ke ʻano he pae laina, ʻike ʻia e hāʻawi ka ʻōnaehana ʻaʻole i ka pololei o ke kūlana kiʻekiʻe a me ka hoʻihoʻi hou ʻana, akā me nā hewa angular haʻahaʻa a me nā planar.No ka hoʻokō ʻana i kēia pae o ka hana, aia kekahi mau loina a nā mea hana maʻamau e hahai ma ke ʻano o ke kūkulu ʻana a me ke ʻano o nā ʻāpana i hoʻohana ʻia i ka hoʻolālā kahua.
Ke hoʻohana nei kēia pae laina i nā bearings recirculating profiled me kahi kaʻa kaʻa laina.
ʻO ka mea mua, ʻaʻole like me nā ʻōnaehana neʻe laina ʻē aʻe, ka mea maʻamau e hoʻohana i ka extrusion aluminika a i ʻole ka pā ma ke ʻano he kumu, hoʻomaka kahi laina laina me kahi kumu kumu-pololei.ʻO nā pae i hoʻolālā ʻia no nā pae kiʻekiʻe o ka palahalaha, pololei, a me ka rigidity e hoʻohana pinepine i kahi kumu i hana ʻia me ke kila a i ʻole ka granite, ʻoiai hoʻohana ʻia ka alumini i kekahi mau hoʻolālā.ʻO ke kila a me ka granite he haʻahaʻa haʻahaʻa o ka hoʻonui wela ma mua o ka alumini, no laila ke hōʻike nei lākou i ke kūpaʻa ʻoi aku ka maikaʻi ma nā wahi me nā wela kiʻekiʻe a ʻokoʻa paha.
Hāʻawi pū ka ʻōnaehana alakaʻi laina i ka pololei a me ka palahalaha o ka huakaʻi, no laila, ʻo nā alakaʻi alakaʻi i koho ʻia no kahi pae laina he kiʻekiʻe kiʻekiʻe kiʻekiʻe.nā paheʻe keʻa, a i ʻolenā ʻea ea.Hāʻawi kēia mau ʻōnaehana alakaʻi i ke kākoʻo ʻoʻoleʻa loa e hōʻemi i nā hewa angular, hiki ke alakaʻi i nā hewa ʻo Abbé ke loaʻa kahi offset ma waena o ke kumu o ka hewa (ke alakaʻi) a me ka wahi hoihoi (wahi mea hana a i ʻole ke kūlana ukana).
ʻOiai he nui nā ʻano o nā ʻōnaehana laina laina e hoʻohana ana i nā mīkini hoʻokele kiʻekiʻe, hoʻohana nui nā pae laina i hoʻokahi o nā ʻenehana ʻelua: kahi wili pōlele kiʻekiʻe-pololei a i ʻole ka laina laina.Hāʻawi maʻamau nā kaʻa laina laina i ka pae kiʻekiʻe o ka pololei o ka hoʻonohonoho ʻana a me ka hoʻihoʻi hou ʻana, no ka mea, hoʻopau lākou i ka hoʻokō a me ka backlash i loaʻa i loko o kahi kaʻa kaʻa a me ka hui ʻana ma waena o ke kaʻa a me ke kaʻa.No ka hihia kūikawā o nā hana hoʻonohonoho sub-micron,piezo actuatorsa i ʻolenā motika leo wiliʻO ka mea maʻamau ka mīkini hoʻokele i koho ʻia, no kā lākou neʻe pololei loa, hiki ke hana hou.
ʻOiai ʻo ka huaʻōlelo "linear stage" e pili ana i kahi ʻōnaehana neʻe axis hoʻokahi, hiki ke hoʻohui ʻia nā pae e hana i nā ʻōnaehana multi-axis e like me nā pae XY,pae hoʻolālā, a me nā pae gantry.
Ke hoʻohana nei kēia ʻāpana gantry ʻelua-axis i nā bearing ea a me nā kaʻa laina laina ma kahi kumu seramika.
