Sayansi ya Kukhazikika: Kusankha Zipangizo za Zipangizo za Metrology za M'badwo Wotsatira

Mu mafakitale amakono, komwe kusiyana pakati pa gawo la ndege logwira ntchito bwino kwambiri ndi kulephera kwakukulu kumayesedwa mu nanometers, kukhulupirika kwa kapangidwe ka makina oyezera sikungatheke kukambirana. Pamene mainjiniya ndi oyang'anira ma labotale abwino akuyesa mbadwo wotsatira wa zida zoyezera, mkanganowu nthawi zambiri umabwerera ku funso lofunika kwambiri: Ndi zinthu ziti zomwe ziyenera kukhala maziko a kulondola?

Ku ZHHIMG, timadziwa bwino ntchito yokonza mapulatifomu olimba kwambiri. Kumvetsetsa kusiyana pakati pa maziko a makina a granite ndi maziko a makina achitsulo ndikofunikira kwambiri pa malo aliwonse omwe cholinga chake ndi kubwerezabwereza kwa sub-micron.

Chofunika Kwambiri: Chifukwa Chake Kusankha Zinthu Zofunika

Makina Oyezera Zinthu Zonse (CMM) ndi Chida Choyezera Zinthu Zonse (ULMI) zimatsatira malamulo a thermodynamics ndi makina akale. Maziko a zida zimenezi ayenera kukwaniritsa maudindo atatu akuluakulu: kuchepetsa kutentha, kuyamwa kwa kugwedezeka, ndi kukhazikika kwa nthawi yayitali.

Granite vs. Cast Iron: Kusanthula Koyerekeza

Kwa zaka zambiri,maziko a makina achitsuloNgakhale kuti chitsulo chopangidwa ndi chitsulo chimapereka kulimba kwambiri ndipo chingapangidwe m'njira zovuta zamkati, chimachepetsedwa ndi chibadwa chake chachitsulo.

1. Kukulitsa Kutentha: Kuchuluka kwa kutentha kwa chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo ndi pafupifupi kawiri kuposa kwa granite wakuda wachilengedwe. Mu labotale komwe kuwongolera kutentha kumatha kusintha ndi 0.5°C, maziko a chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo amakula ndikuchepa kwambiri kuposa maziko a makina a granite, zomwe zimapangitsa kuti "zolakwika za mizimu" ziwonekere mu deta yoyezera.

2. Kuchepetsa Kugwedezeka: Ngakhale chitsulo chopangidwa ndi chitsulo chili ndi kusungunuka bwino kuposa chitsulo, sichingafanane ndi kapangidwe ka mkati ka granite. Kapangidwe kachilengedwe ka granite kamateteza bwino ku kugwedezeka kwamphamvu komwe kumachitika nthawi zambiri m'malo opangira zinthu zamakono.

3. Kusalowerera kwa Magnetic ndi Dzimbiri: Mosiyana ndi maziko achitsulo, ambale yolondola pamwambakapena maziko a makina opangidwa ndi granite mwachilengedwe sagwiritsa ntchito mphamvu yamagetsi komanso sagwiritsa ntchito mphamvu ya maginito. Sachita dzimbiri, zomwe zikutanthauza kuti safuna mafuta oteteza omwe angadetse ma comparator optical kapena ma laser scales.

CMM ndi ULMI: Zida Zosiyana, Maziko Amodzi

Ngakhale kuti zipangizozo zimapereka kukhazikika, kugwiritsa ntchito kwake kumalamulira mawonekedwe ake. Nthawi zambiri timawona kusiyana kwakukulu pa momwe ma laboratories amagwiritsira ntchito zida zawo.

Kusinthasintha kwa Makina Oyezera Ogwirizana (CMM)

CMM ndiye womasulira padziko lonse lapansi wa opanga zinthu. Mwa kusuntha chofufuzira kudutsa ma axes atatu, imapanga mapasa a digito a gawo lenileni. Chifukwa chakuti mlatho wa CMM umayenda mosinthasintha, kulemera ndi kunyowa kwamaziko a makina a granitendizofunikira kwambiri kuti mupewe kuchedwa kwa inertial. Pa ma CMM othamanga kwambiri, ZHHIMG imapanga maziko kuti atsimikizire kuti pakati pa mphamvu yokoka pakhalebe pansi, kuchepetsa "kugwedezeka" panthawi yothamanga mwachangu.

Kulondola kwa Chida Choyezera Kutalika kwa Padziko Lonse (ULMI)

Pamene CMM imapereka mphamvu zosiyanasiyana za 3D, Chida Choyezera Kutalika Kwathunthu Chimapereka chitsimikizo cha 1D ndi 2D. Nthawi zambiri chimagwiritsidwa ntchito poyesa ma master gauges, ULMI imafuna maziko omwe ali ndi mphamvu zamkati zosakwana zero. Kupotoza kulikonse kwa maziko pakapita nthawi kungapangitse kuti chidacho chisakhale chothandiza pakuyesa. Ichi ndichifukwa chake ma ULMI olondola kwambiri padziko lonse lapansi amagwiritsa ntchito zigawo zakale za granite zomwe zimachepetsedwa ndi kupsinjika.

Kuchepetsa Phokoso la Zachilengedwe

Ngakhale wapamwamba kwambirizida za metrologyzingasokonezedwe ndi malo ozungulira. Chosindikizira cholemera chomwe chikugwira ntchito pamtunda wa mamita 50 kapena forklift yomwe ikuyenda m'nyumba yosungiramo zinthu zingayambitse mafunde amphamvu pansi.

Pofuna kuthana ndi izi, tebulo lodzipatula logwedezeka sililinso lapamwamba—ndilofunikira. Mwa kuphatikiza maziko a makina ndi kusungulumwa kogwira ntchito kapena kosagwira ntchito, ZHHIMG imaonetsetsa kuti envelopu yoyezera imakhalabe yosiyana ndi "phokoso la chivomerezi" cha fakitale. Kugwirizana kumeneku pakati pa maziko a granite okwera kwambiri ndi dongosolo lodzipatula loyankha ndi komwe kumalola kukwaniritsa kulekerera kwa Giredi 000.

Ubwino wa ZHHIMG mu Uinjiniya Wazinthu

Njira yathu yopangira zinthu imaposa kudula miyala kosavuta. Timaona kupanga kwambale yolondola pamwambakapena bedi la makina opangidwa mwamakonda ngati njira yasayansi ya magawo ambiri:

• Kusankha kwa Geological: Si granite yonse yomwe ili yofanana. Timasankha gabbro-diabase chifukwa cha kuchuluka kwake komanso kuyamwa madzi pang'ono.

• Kulumikiza Molondola: Akatswiri athu amagwiritsa ntchito njira zolumikizirana ndi manja zomwe palibe makina a CNC omwe angatsanzire, zomwe zimapangitsa kuti zikhale zosalala zomwe zimakwaniritsa komanso kupitirira miyezo yapadziko lonse lapansi.

• Kuphatikiza Dongosolo: Timapereka dongosolo lonse la zinthu, kuyambira pachiyambimaziko a makina achitsulokuti igwiritsidwe ntchito kwambiri m'mafakitale ku nyumba za granite zoyengedwa bwino kwambiri kuti ziwunikiridwe ndi semiconductor.

Mapeto Abwino a Malo Osungira Zinthu Olondola Kwambiri

Kusankha pakati pa zipangizo ndi mitundu ya zida ndi njira yogwiritsira ntchito bwino, malo okhala, komanso kusatsimikizika komwe kumafunika. Ngakhale kuti chitsulo chopangidwa ndi chitsulo chikadali ndi malo m'malo opangira zinthu zolemera, dziko la metrology lapita patsogolo kwambiri ku kukhazikika kwa granite ndi kupondereza kwapamwamba kwa kuponyedwa kwa mchere.

Kuyika ndalama mu ZHHIMG Foundation kumatsimikizira kutizida za metrology—kaya ndi choyerekeza cha kuwala kapena CMM yokhala ndi axis yambiri—imagwira ntchito pamalo okhazikika kwambiri. Pofuna kulondola, maziko si gawo la makina okha; ndi gawo lofunika kwambiri pakuyeza.
