Mu metrology yolondola komanso kusonkhana kwa makina, kudalirika nthawi zambiri kumaganiziridwa kuti ndi chifukwa cha kulekerera kapangidwe ndi kulondola kwa makina. Komabe, chinthu chimodzi chofunikira nthawi zambiri chimachepetsedwa: njira yomwe imagwiritsidwa ntchito kuphatikiza zinthu zolumikizidwa mu kapangidwe ka granite. Pazigawo monga ma granite angle plates ndi ma precision gauges, kugwiritsa ntchito kwambiri zinthu zomatira zitsulo kumadzetsa chiopsezo chobisika koma chachikulu—chomwe chingasokoneze kulondola komanso kulimba kwa nthawi yayitali.
Granite yakhala ikudziwika kwa nthawi yayitali ngati chinthu chabwino kwambiri chogwiritsidwa ntchito poyesa zinthu chifukwa cha kukhazikika kwake kwa kutentha, kuuma kwake kwambiri, komanso kuletsa kugwedezeka kwachilengedwe. Komabe, chifukwa granite singathe kulumikizidwa mwachindunji monga zitsulo, opanga nthawi zambiri amagwiritsa ntchito zitsulo zomangira kuti apereke malo omangira. Zinthu zomangira izi zomwe zimapangidwa mu granite nthawi zambiri zimamangidwa pogwiritsa ntchito zomatira zamafakitale, zomwe zimapangitsa kuti pakhale kulumikizana pakati pa zipangizo ziwiri zosiyana kwambiri: mwala wa kristalo ndi chitsulo chosungunuka.
Poyamba, njira iyi ikuwoneka yothandiza. Komabe, pansi pa zochitika zenizeni zogwirira ntchito, zoletsa zimaonekera. Zomangira zomatira zimakhala zodziwika bwino ku zinthu zachilengedwe monga kusinthasintha kwa kutentha, chinyezi, ndi kayendedwe ka makina odzaza. Pakapita nthawi, ngakhale kukula pang'ono pakati pa chitsulo choyikapo ndi granite substrate kungayambitse kupsinjika pang'ono pa malo olumikizirana. Kupsinjika kumeneku kumawonjezeka, zomwe zimapangitsa kuti guluu liwonongeke pang'onopang'ono.
Zotsatira zake zimakhala zobisika poyamba. Kumasula pang'ono kwa choyikapo sikungakhudze nthawi yomweyo kusonkhana, koma pakugwiritsa ntchito molondola kwambiri, ngakhale kusintha kwa micron-level kungayambitse zolakwika zoyezeka. Pamene chomangira chikupitirira kufooka, choyikapocho chingayambe kuwonetsa kusewera kozungulira kapena kusuntha kwa axial. Nthawi zambiri, kugawanika kwathunthu kungachitike, zomwe zimapangitsa kuti gawolo lisagwiritsidwe ntchito komanso kuwononga zida zapafupi.
Kwa opanga makina omwe amagwira ntchito ndi ma granite angle plates kapena zida zina zolondola, kulephera kumeneku kumabweretsa chiopsezo chachikulu. Mosiyana ndi kuwonongeka kapena kusinthika kooneka, kulephera kwa zomatira nthawi zambiri kumakhala mkati ndipo kumakhala kovuta kuzindikira mpaka magwiridwe antchito atasokonekera kale. Ichi ndichifukwa chake vutoli limafotokozedwa bwino ngati "ngozi yobisika" - limagwira ntchito mwakachetechete, ndikuwononga umphumphu wa dongosolo pakapita nthawi.
Njira zamakono zopangira zinthu zayamba kuthana ndi vuto limeneli kudzera m'njira ziwiri zazikulu: makina otsekera ndi kapangidwe ka granite kamodzi. Kutsekera ndi makina kumaphatikizapo kupanga zinthu zokhala ndi mawonekedwe a geometric—monga kudula kapena njira zokulitsa—zomwe zimamangirira mkati mwa granite. Ngakhale izi zimathandiza kuti zinthu zisungike bwino poyerekeza ndi zomatira zosavuta, zimadalirabe umphumphu wa kulumikizana pakati pa zinthu zosiyana.
Yankho lolimba kwambiri ndi kapangidwe ka granite kamodzi. Mu njira iyi, mawonekedwe olondola amapangidwa mwachindunji mu chipika cha granite pogwiritsa ntchito ukadaulo wapamwamba wa CNC ndi ukadaulo wa ultrasonic machining. M'malo moyika zigawo zachitsulo zosiyana, kapangidwe kake kamachepetsa ma interfaces onse. Pamene ntchito yolumikizidwa ndi ulusi ikufunika, njira zina zomangira kapena machitidwe ophatikizidwa amaphatikizidwa panthawi yopanga mwanjira yomwe imatsimikizira kuti kapangidwe kake kamakhala koyenera.
Ubwino wa kapangidwe ka granite kamodzi uli pakuchotsa malo ofooka. Popanda zigawo zomatira kapena zolumikizira zolumikizira, palibe chiopsezo cha kuwonongeka kwa ma bond. Zinthuzo zimakhala ngati kapangidwe kamodzi, kogwirizana, zimasunga kukhazikika kwake kwa nthawi yayitali komanso pansi pa mikhalidwe yosiyanasiyana yachilengedwe. Izi zikutanthauza mwachindunji kuti kulondola kwake kusungidwa bwino, kuchepetsa kukonza, komanso nthawi yayitali yogwirira ntchito.
Kuchokera ku lingaliro la fizikiki, kuchotsa ma interfaces kumachotsanso kuchuluka kwa kupsinjika komwe kumachitika m'deralo. Mu makina oyikamo glued, kusamutsa katundu kumachitika kudzera mu guluu, komwe kumatha kuwonetsa khalidwe losakhala la mzere pansi pa kupsinjika. Mosiyana ndi zimenezi, kapangidwe ka granite kakang'ono kamagawa mphamvu mofanana, kusunga kuuma kwachilengedwe ndi makhalidwe oletsa kuzizira kwa chinthucho.
Kwa mafakitale monga kupanga zinthu za semiconductor, kuwunika ndege, ndi zida zolondola, komwe kulekerera kumayesedwa mu ma micron kapena nanometers, kusiyana kumeneku sikophweka. Kuyika kolakwika kungayambitse kusalinganika bwino, kusinthasintha kwa muyeso, ndipo pamapeto pake, kukonzanso kokwera mtengo kapena kulephera kwa chinthu. Mwa kugwiritsa ntchito njira imodzi ya granite, mainjiniya amatha kuchepetsa zoopsazi pagawo lopanga m'malo mozithetsa pambuyo poti zalephera.
Pamene ziyembekezo za kulondola ndi kudalirika zikupitirira kukwera, zofooka za njira zachikhalidwe zopangira zinthu zikuonekera kwambiri. Zoyikapo zomatira, zomwe kale zinkaonedwa ngati zovomerezeka, tsopano ndi vuto pa ntchito zapamwamba. Kusintha kwa granite yopangidwa ndi makina amodzi sikungowonjezera pang'onopang'ono—ndi kuganiziranso momwe mapangidwe olondola ayenera kupangidwira ndikupangidwira.
Kwa makampani omwe akufuna kupititsa patsogolo magwiridwe antchito ndi moyo wautali wa machitidwe awo oyezera, uthengawo ndi womveka bwino: kuchotsa zoopsa zobisika ndikofunikira monga momwe kukwaniritsira kulondola koyambirira. Pankhaniyi, kumanga granite yokhala ndi chidutswa chimodzi kumawonekera ngati njira yodalirika kwambiri yopitira patsogolo, yopereka mulingo wa umphumphu womwe zinthu zomangira zomwe zili ndi ma bond sizingafanane.
