Chifukwa Chake Makulidwe a Platform ya Granite Ndiwo Mfungulo Yakukweza Kutha ndi Kulondola kwa Sub-Micron

Mainjiniya ndi akatswiri a metrologist akamasankha nsanja yolondola kwambiri ya granite kuti muyezedwe ndi ntchito zophatikizira, lingaliro lomaliza nthawi zambiri limakhazikika pazigawo zowoneka ngati zosavuta: makulidwe ake. Komabe, makulidwe a mbale ya granite ndi yochulukirapo kuposa gawo losavuta-ndilo maziko omwe amalamulira mphamvu yake yolemetsa, kugwedezeka kwake, ndipo pamapeto pake, kuthekera kwake kukhalabe okhazikika kwanthawi yayitali.

Pazogwiritsa ntchito zolondola kwambiri, makulidwe ake samasankhidwa mwachisawawa; ndi kuwerengera kofunikira kwa uinjiniya kutengera miyezo yokhazikitsidwa ndi mfundo zokhwima zamakina opatuka.

The Engineering Standard Kumbuyo Makulidwe Kutsimikiza

Cholinga chachikulu cha nsanja yolondola ndikugwira ntchito ngati ndege yathyathyathya, yosasunthika. Chifukwa chake, makulidwe a mbale ya granite amawerengedwa kuti awonetsetse kuti pansi pa katundu wake woyembekezeka, kukhazikika kwa mbaleyo kumakhalabe mkati mwa kalasi yake yololera (mwachitsanzo, Gulu AA, A, kapena B).

Mapangidwe awa amatsatira malangizo otsogola amakampani, monga muyezo wa ASME B89.3.7. Mfundo yofunikira pakutsimikiza makulidwe ndikuchepetsa kupatuka kapena kupindika. Timawerengera makulidwe ofunikira poganizira zamtundu wa granite-makamaka Young's Modulus of Elasticity (muyeso wa kuuma) -pamodzi ndi miyeso yonse ya mbale ndi katundu woyembekezeredwa.

Muyezo wa Authority pa Kutha Kwakatundu

Mulingo wovomerezeka wa ASME umalumikiza makulidwe molunjika ku mphamvu yonyamulira mbale pogwiritsa ntchito malire achitetezo:

Ulamuliro Wokhazikika: Pulatifomu ya granite iyenera kukhala yokhuthala mokwanira kuti ithandizire katundu wamba womwe umagwiritsidwa ntchito pakatikati pa mbaleyo, popanda kupotoza mbaleyo motsatana ndi diagonal yoposa theka la kulolerana kwake konse.

Chofunikira ichi chimawonetsetsa kuti makulidwe ake kumapereka kulimba kofunikira kuti mutenge kulemera komwe kumagwiritsidwa ntchito ndikusunga kulondola kwa sub-micron. Kwa nsanja yayikulu kapena yodzaza kwambiri, makulidwe ofunikira amawonjezeka kwambiri kuti athe kuthana ndi nthawi yopindika.

Makulidwe: The Triple Factor in Precision Stability

Kukula kwa nsanja kumachita ngati amplifier mwachindunji cha kukhulupirika kwake. Mbale yokhuthala imapereka maubwino atatu olumikizana, ofunikira pakulondola kwa metrology:

1. Kuthekera kwa Katundu Wokwezeka ndi Kusungidwa Kwa Flatness

Kukula ndikofunikira pokana nthawi yopindika chifukwa cha zinthu zolemetsa, monga makina akulu oyezera (CMMs) kapena zida zolemetsa. Kusankha makulidwe omwe amaposa zofunikira zochepa kumapereka malire achitetezo ofunikira. Izi owonjezera zinthu amapereka nsanja zofunika misa ndi dongosolo mkati kugawira katundu bwino, motero kuchepetsa kwambiri kupotoza mbale ndi kuonetsetsa chofunika pamwamba flatness anakhalabe pa nsanja moyo wonse.

2. Kuchulukitsa Kukhazikika Kwamphamvu ndi Kuthamanga Kwakugwedezeka

Mwala wokhuthala, wolemera kwambiri wa granite mwachibadwa umakhala ndi mphamvu zokulirapo, zomwe ndizofunikira kwambiri pakuchepetsa phokoso lamakina ndi lamayimbidwe. Pulatifomu yayikulu imakhala ndi ma frequency ochepera achilengedwe, zomwe zimapangitsa kuti isavutike kwambiri ndi kugwedezeka kwakunja ndi zivomezi zomwe zimachitika m'mafakitale. Kunyowa kwapang'onopang'ono kumeneku ndikofunikira pakuwunika kwapamwamba kwambiri komanso makina olumikizirana ndi laser pomwe ngakhale kuyenda kowoneka bwino kumatha kuwononga njira.

3. Kupititsa patsogolo Kutentha kwa Inertia

Kuchuluka kwa zinthu kumachepetsa kusinthasintha kwa kutentha. Ngakhale kuti granite yapamwamba imakhala kale ndi mphamvu yochepa kwambiri ya kukula kwa matenthedwe, makulidwe akuluakulu amapereka inertia yotentha kwambiri. Izi zimalepheretsa kutentha kwachangu, kosafanana komwe kumatha kuchitika makina akatenthetsa kapena kutenthetsa mpweya, kuwonetsetsa kuti geometry ya nsanja imakhalabe yosasinthika komanso yokhazikika pakanthawi yayitali.

M'dziko la uinjiniya wolondola, makulidwe a nsanja ya granite si chinthu chochepetsera kuti muchepetse mtengo, koma ndichinthu chofunikira kuti muwongolere, kuwonetsetsa kuti kukhazikitsidwa kwanu kumapereka zotsatira zobwerezabwereza komanso zotsatirika zomwe zimafunidwa ndi kupanga zamakono.
