Mu metrology yamakono, kulondola si chinthu chimodzi chokha—ndi zotsatira za machitidwe a zinthu, kapangidwe ka makina, kuwongolera chilengedwe, ndi njira yoyezera. Pakati pa zinthu izi, kusankha zinthu za zigawo za kapangidwe kake kumachita gawo lofunikira. Pa makina oyezera ogwirizana (CMMs), komwe kubwerezabwereza ndi kutsata ndizofunikira kwambiri, zigawo za granite zolondola zakhala zinthu zomwe zimasankhidwa pamaziko, njira zoyendetsera zinthu, ndi malo ofotokozera. Kusintha kumeneku sikungowonetsa ubwino wochita zinthu mwamwambo komanso kumvetsetsa kwakukulu momwe zinthu za zinthu zimakhudzira mwachindunji kulondola kwa muyeso.
Ma CMM amagwira ntchito mkati mwa ma micron ndi ma sub-micron tolerances omwe amachulukirachulukira. Kaya amagwiritsidwa ntchito popanga magalimoto, kutsimikizira magawo a ndege, kuyang'anira ma semiconductor, kapena kutsimikizira zida molondola, machitidwe awa ayenera kupereka miyeso yokhazikika komanso yobwerezabwereza pansi pa mikhalidwe yosiyanasiyana yachilengedwe. Chifukwa chake, zinthu zomwe zimathandiza njira yoyezera - nthawi zambiri maziko ndi mlatho - ziyenera kupereka kukhazikika kwapadera, kugwedezeka, komanso kukana kusokonezeka kwa chilengedwe. Granite, makamaka granite wakuda wopangidwa kuti agwiritsidwe ntchito poyesa, imakwaniritsa zofunikira izi bwino kwambiri kuposa zipangizo zachikhalidwe monga chitsulo chosungunuka kapena chitsulo.
Chimodzi mwa zinthu zofunika kwambiri pa granite mu CMM ndi mphamvu yake yochepetsera kugwedezeka. Kulondola kwa muyeso kumadalira kwambiri kuthekera kosunga kukhazikika kwa probe panthawi yofufuza kapena kupeza mfundo. Kugwedezeka kwakunja—kuchokera ku makina apafupi, kuyenda kwa mapazi, kapena ngakhale zomangamanga—kungayambitse phokoso mu dongosolo loyezera. Kapangidwe ka kristalo ka mkati mwa granite kamachotsa mphamvu yogwedezeka m'malo moitumiza, zomwe zimachepetsa kwambiri kusokonezeka kwa mphamvu. Katunduyu ndi wofunika kwambiri mu CMM zowunikira mwachangu, komwe kuyenda kwa probe mwachangu kumatha kukulitsa kugwedezeka pang'ono kwa kapangidwe.
Khalidwe la kutentha ndi chinthu china chofunikira kwambiri. Zipangizo zonse zimakula ndikuchepa ndi kusintha kwa kutentha, koma liwiro ndi kufanana kwa kukulaku kumasiyana kwambiri. Granite imasonyeza kuchuluka kochepa kwa kutentha ndipo, chofunika kwambiri, imayankha pang'onopang'ono kusinthasintha kwa kutentha. Kusakhazikika kwa kutentha kumeneku kumalola kuti mapangidwe a CMM okhala ndi granite akhalebe olimba kwa nthawi yayitali, ngakhale m'malo omwe kutentha sikuli kofanana bwino. Mosiyana ndi zimenezi, zitsulo monga chitsulo zimayankha mwachangu kusintha kwa malo, zomwe zingachititse kuti muyeso ukhale wochepa. Kwa ma laboratories a metrology omwe akuyesetsa kusunga zinthu zogwirizana ndi ISO, kusiyana kumeneku kungakhudze mwachindunji bajeti zosatsimikizika.
Kulimba kwa pamwamba ndi kukana kuvala kumathandizanso kuti granite ikhale yabwino kwambiri poyesa molondola. Malo a granite omwe amagwiritsidwa ntchito mu CMM nthawi zambiri amapindika kuti akhale osalala kwambiri—nthawi zambiri mkati mwa ma microns ochepa m'malo akuluakulu. Akapezeka, kusalala kumeneku kumakhala kokhazikika pakapita nthawi chifukwa cha kuuma kwa granite komanso kukana kuvala. Mosiyana ndi malo achitsulo, omwe angasinthe mawonekedwe, kukanda, kapena kufunikira kukonzanso nthawi ndi nthawi, granite imasunga umphumphu wake wa geometrical popanda kukonza kwambiri. Kukhazikika kumeneku kumatsimikizira kuti mizere yolozera imakhalabe yofanana, kuthandizira kudalirika kwa nthawi yayitali pakuyeza.
Ubwino wina uli mu chitetezo cha granite ku dzimbiri ndi kuwonongeka kwa mankhwala. Malo okhala ndi Metrology nthawi zambiri amakhala ndi mafuta, zoziziritsira, zotsukira, ndi chinyezi chosiyanasiyana. Zitsulo ndi zitsulo zotayidwa zingafunike zokutira zoteteza kapena malo olamulidwa kuti apewe kukhuthala. Granite, popeza ndi mwala wachilengedwe, imalimbana ndi zinthu zotere. Izi zimapangitsa kuti ikhale yoyenera kwambiri m'zipinda zoyera ndi m'ma laboratories komwe kuwongolera kuipitsidwa ndi kukhazikika kwa zinthu ndikofunikira kwambiri.
Kuchokera ku lingaliro la uinjiniya wa kapangidwe kake, granite imapereka kulimba kwabwino kwambiri ikapangidwa bwino. Ngakhale kuti ndi yofooka kwambiri kuposa zitsulo, njira zamakono zopangira zimalola kuphatikiza zinthu zolumikizidwa ndi ulusi, ma bonded assemblies, ndi zomangamanga zosakanikirana zomwe zimaphatikiza granite ndi zigawo zachitsulo komwe kuli kofunikira. Kusanthula kwa Finite element (FEA) nthawi zambiri kumagwiritsidwa ntchito kukonza mawonekedwe a maziko a granite CMM, kuonetsetsa kuti kuuma ndi kugawa katundu zikugwirizana ndi zofunikira pakugwira ntchito popanda kuwononga umphumphu wa zinthu. Zotsatira zake ndi kapangidwe komwe kamalinganiza kulimba ndi kunyowa - zinthu ziwiri zomwe nthawi zambiri zimakhala zogwirizana m'makina achitsulo.
Ntchito ya zigawo za granite yolondola imapitirira kupitirira maziko. Njira zoyendetsera, malo onyamula mpweya, ndi mafelemu a metrology zimawonjezera zinthu za granite kuti ziwonjezere magwiridwe antchito a dongosolo. Makina onyamula mpweya, makamaka, amapindula ndi ubwino ndi kukhazikika kwa pamwamba pa granite. Kugwirizana pakati pa filimu ya mpweya ndi pamwamba pa granite kuyenera kukhala kogwirizana komanso kopanda ma disformations ang'onoang'ono kuti zitsimikizire kuyenda kosalala, kopanda kukangana. Kupatuka kulikonse kungayambitse zolakwika zoyikira, zomwe zimakhudza mwachindunji kulondola kwa muyeso. Kuthekera kwa granite kusunga malo osalala pansi pa katundu kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito motere.
Kulondola kwa muyeso mu CMM nthawi zambiri kumatanthauzidwa malinga ndi cholakwika chachikulu chovomerezeka (MPE), kubwerezabwereza, ndi kusatsimikizika. Chilichonse mwa izi chimakhudzidwa ndi kukhazikika kwa kapangidwe ka makina. Mwachitsanzo, kubwerezabwereza kumadalira kuthekera kwa makina kubwerera pamalo omwewo pansi pa mikhalidwe yofanana. Kusintha kwa kapangidwe kake, kaya chifukwa cha kukula kwa kutentha kapena kupsinjika kwa makina, kungasokoneze luso ili. Kukhazikika kwa miyeso ya Granite kumachepetsa kusiyanasiyana kotere, kuthandizira kufotokozera kolimba kwa kubwerezabwereza. Mofananamo, bajeti zosatsimikizika—zomwe zimapanga magwero onse a zolakwika zoyezera—zimapindula ndi khalidwe lodziwikiratu la zigawo za granite.
Ndikofunikanso kuganizira za magwiridwe antchito a nthawi yayitali. Zipangizo za Metrology nthawi zambiri zimayembekezeredwa kuti zizigwira ntchito modalirika kwa zaka zambiri, popanda kuwonongeka kwenikweni. Zipangizo zomwe zimawonetsa kugwedezeka, kupumula kwa kupsinjika, kapena kusintha pang'onopang'ono zimatha kufooketsa chiyembekezo ichi. Granite, yomwe idapangidwa chifukwa cha kupsinjika kwa nthaka kwa zaka mamiliyoni ambiri, imachepetsedwa mwachilengedwe kupsinjika. Ikapangidwa ndi makina ndikukhazikika, siwonetsa mtundu womwewo wa kupsinjika kwamkati komwe kumapezeka m'mapangidwe achitsulo kapena olumikizidwa. Izi zimapangitsa kuti ikhale yoyenera kwambiri kugwiritsidwa ntchito komwe kukhulupirika kwa nthawi yayitali ndikofunikira.
Kupita patsogolo kwa ukadaulo wopanga zinthu kwawonjezera mphamvu ya zigawo za granite. Kupera molondola, makina a CNC, ndi njira zolumikizira diamondi zimathandiza kupanga ma geometries ovuta molondola kwambiri. Kuphatikiza apo, ukadaulo wamakono wogwirizanitsa umalola kusonkhanitsa nyumba zazikulu za granite popanda kuyambitsa kupsinjika kwakukulu. Mphamvu izi zakulitsa mwayi wopanga mapangidwe a opanga CMM, zomwe zapangitsa kuti makina azikhala ochepa, ogwira ntchito bwino, komanso ogwira ntchito bwino.
Kuyerekeza pakati pa granite ndi zipangizo zina sikungokhala kwamaphunziro okha—kumabweretsa zotsatira zachindunji pakugwira ntchito bwino komanso ubwino wa zinthu. M'mafakitale monga kupanga zinthu za semiconductor, komwe kukula kwa zinthu kumayesedwa mu nanometers, ngakhale cholakwika chochepa kwambiri choyezera chingayambitse kutayika kwakukulu kwa zokolola. Mu ndege, komwe zigawo zofunika kwambiri pachitetezo ziyenera kukwaniritsa kulekerera kolimba, kulondola kwa muyeso kumalumikizidwa mwachindunji ndi kudalirika ndi kutsatira malamulo. M'mikhalidwe yotereyi, kusankha zinthu za zigawo za CMM kumakhala chisankho chanzeru osati chaukadaulo wokha.
Zinthu zokhudzana ndi chilengedwe zikuyamba kutchuka. Granite, monga chinthu chachilengedwe, imafuna kukonza zinthu mopanda mphamvu zambiri poyerekeza ndi zitsulo. Ngakhale kuti kukumba miyala ndi makina kumakhudza chilengedwe, kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito popanga granite kumatha kukhala kochepa, makamaka ngati nthawi yawo yayitali ikuganiziridwa. Kuchepa kwa kufunika kosintha ndi kukonza kumathandizanso kuti pakhale zolinga zokhazikika, zomwe zikugwirizana ndi zomwe makampani ambiri amachita popanga zinthu zobiriwira.
Ngakhale ubwino wake, granite ili ndi zovuta. Kufooka kwake kumafuna kusamalidwa mosamala panthawi yonyamula ndi kuyiyika. Zoganizira za kapangidwe kake ziyenera kuganizira kufalikira kwa katundu ndi mphamvu zomwe zingakhudze. Kuphatikiza apo, granite yopangira imafuna zida zapadera komanso ukatswiri, zomwe zingakhudze nthawi yogwiritsira ntchito komanso mtengo wake. Komabe, zovuta izi zimamveka bwino m'makampani ndipo nthawi zambiri zimakhala zochepa kuposa zabwino zomwe zingachitike.
Poganizira zamtsogolo, kuphatikiza machitidwe anzeru a metrology, automation, ndi ukadaulo wa digito kudzaika zofunikira kwambiri pa kukhazikika kwa kapangidwe kake. Pamene ma CMM akuphatikizidwa kwambiri mu mizere yopanga yokha komanso machitidwe owongolera khalidwe nthawi yeniyeni, kulekerera kwa kusinthasintha kwa muyeso kudzapitirira kuchepa. Zipangizo zomwe zingatsimikizire magwiridwe antchito okhazikika pansi pa mikhalidwe yosinthika zidzakhala zofunikira. Granite, yokhala ndi kuphatikiza kwake kwapadera kwa damping, kukhazikika, ndi kulimba, ili pamalo abwino othandizira kusinthaku.
Pomaliza, kugwiritsa ntchito zigawo za granite yolondola mu CMMs si nkhani yachikhalidwe kapena kukonda chabe—ndi yankho ku zofunikira zazikulu zoyezera molondola kwambiri. Kusankha zinthu kumakhudza mwachindunji machitidwe a kugwedezeka, kukhazikika kwa kutentha, kulimba kwa pamwamba, ndi kudalirika kwa nthawi yayitali, zonse zomwe zimathandiza kuti muyese molondola. Pamene mafakitale akukankhira malire a kulondola, ntchito ya granite mu machitidwe a metrology idzakhala yofunika kwambiri. Kwa opanga ndi ma laboratories omwe akufuna kukonza luso lawo loyezera, kumvetsetsa ndi kugwiritsa ntchito makhalidwe a granite sikofunikira—ndikofunikira.
