Mu dziko lapadera la kupanga zinthu zolemera—kumene mapiko a ndege, malo oimikapo ma turbine amphepo, ndi chassis yamagalimoto amabadwira—kukula kwa chinthu nthawi zambiri kumakhala chopinga chachikulu pakutsimikizira kwake. Chigawo chikafika mamita angapo, zinthu zofunika kuziyeza zimakwera kwambiri. Sikuti kungopeza cholakwika chokha; koma kuonetsetsa kuti kupanga zinthu kumayenda bwino kwa madola mamiliyoni ambiri. Izi zapangitsa atsogoleri ambiri amakampani kufunsa kuti: Kodi tingasunge bwanji kulondola kwa labotale pamene chogwirira ntchito chili chachikulu ngati galimoto? Yankho lake lili mu kapangidwe koyambira ka malo oyezera, makamaka kusintha kupita ku makina olemera a gantry ndi zipangizo zamakono zomwe zimawathandiza.
Kumvetsetsa kusiyana pakati pa cmm resolution ndi kulondola ndi gawo loyamba pakumvetsetsa metrology yayikulu. Mu msonkhano waukulu, high resolution imalola sensa kuzindikira kusiyana pang'ono kwambiri kwa pamwamba, koma popanda kulondola kwenikweni, mfundo za datazo "zimatayika mumlengalenga." Kulondola ndi kuthekera kwa dongosolo kukuuzani komwe mfundoyo ili mu dongosolo lapadziko lonse lapansi poyerekeza ndi chitsanzo cha CAD. Pa makina akuluakulu, kukwaniritsa izi kumafuna ubale wogwirizana pakati pa masensa amagetsi ndi chimango chakuthupi cha makinawo. Ngati chimangocho chimasintha kapena kuchitapo kanthu ku kutentha, ngakhale sensa yapamwamba kwambiri padziko lonse lapansi idzabweza deta yolakwika.
Pofuna kuthetsa izi, mainjiniya aZigawo za Makina Oyezera a M'mbali Zonsechakhala malo ofunikira kwambiri kwa opereka metrology apamwamba. Pogwiritsa ntchito kapangidwe ka mizere iwiri kapena iwiri, makinawa amatha kuyang'ana mbali zonse ziwiri za workpiece yayikulu nthawi imodzi kapena kugwira zinthu zazikulu kwambiri zomwe sizingatheke pa CMM yachikhalidwe. Njira yofananayi simangowirikiza kawiri kuchuluka kwa zinthu; imapereka katundu wolinganizika bwino wamakina, womwe ndi wofunikira kwambiri kuti ukhale wobwerezabwereza kwa nthawi yayitali. Mukayesa gawo la mamita asanu, kulumikizana kwa makina kwa zigawo ziwirizi ndi komwe kumatsimikizira kuti "dzanja lamanzere likudziwa zomwe dzanja lamanja likuchita," zomwe zimapereka gawo logwirizana komanso lolondola kwambiri la digito.
Chida chachinsinsi chopezera kukhazikika kumeneku ndi kugwiritsa ntchito granite yolondola pakupanga makina oyezera a Bilateral Measuring Machine. Ngakhale kuti chitsulo ndi aluminiyamu zili ndi malo awo opepuka, zimatha kukhudzidwa ndi "kusuntha kwa kutentha" - kukula ndi kuchepa pang'ono ndi kusintha pang'ono kwa kutentha kwa fakitale. Granite, makamaka gabbro wakuda wapamwamba kwambiri, imakalamba mwachilengedwe kwa zaka mamiliyoni ambiri, zomwe zimapangitsa kuti ikhale yokhazikika kwambiri. Kuchuluka kwake kochepa kwa kutentha komanso mphamvu zake zogwedera kwambiri zikutanthauza kuti "zero point" ya makinawo imakhalabe pamalopo, ngakhale m'malo ogulitsira omwe samayang'aniridwa ndi nyengo. Mudziko la metrology yapamwamba, granite si maziko okha; ndi chitsimikizo cha chete cha micron iliyonse yoyesedwa.
Pa ntchito "zazikulu" zenizeni,Bedi Lalikulu Loyezera GantryChimayimira chigoli chachikulu cha muyeso wa mafakitale. Mabedi awa nthawi zambiri amaikidwa pansi pa fakitale, zomwe zimathandiza kuti zinthu zolemera ziyendetsedwe kapena kukwezedwa mwachindunji mu kuchuluka kwa muyeso. Kapangidwe ka mabedi awa ndi ntchito yaukadaulo wa zomangamanga ndi wamakina. Ayenera kukhala olimba mokwanira kuti athandizire kulemera kwa matani makumi ambiri popanda ngakhale kupotoka pang'ono. Mwa kuphatikiza ma gantry rails mwachindunji mu bedi lokhazikika, lolimbikitsidwa ndi granite, opanga amatha kupeza kulondola kwa volumetric komwe kale kunkagwiritsidwa ntchito pazida zazing'ono za labu. Izi zimathandiza kuti pakhale njira yowunikira "kamodzi kokha" komwe kuponyera kwakukulu kumatha kutsimikiziridwa, kupangidwa ndi makina, ndikutsimikiziridwanso popanda kuchoka pamalo opangira.
Kwa makampani omwe amagwira ntchito m'magawo a ndege ndi mphamvu ku North America ndi ku Europe, mulingo uwu waukadaulo ndi wofunikira kwambiri kuti achite bizinesi. Sakufuna chida "chokwanira"; akufunafuna mnzake womvetsetsa fizikisi ya muyeso pamlingo waukulu. Kugwirizana kwa masensa okhala ndi mawonekedwe apamwamba, kuyenda kwa mbali ziwiri, ndi kutentha kwa granite yolondola kumapanga malo omwe khalidwe limakhala losasinthika, osati losinthasintha. Pamene tikukankhira malire a zomwe anthu angapange, makina omwe timagwiritsa ntchito poyesa zolengedwazo ayenera kumangidwa mosamala kwambiri. Pamapeto pake, muyeso wolondola kwambiri si nambala yokha—ndi maziko a chitetezo ndi luso latsopano m'dziko lomwe limafuna ungwiro.
