Mu dziko lofunika kwambiri pakupanga zinthu molondola, kudalira sikumangika pa ma algorithms a mapulogalamu okha—kumadalira pa fizikisi. Kaya mukugwiritsa ntchito makina oyezera zinthu (CMM) kuti mutsimikizire masamba a turbine a aerospace kapena scanner ya 3D yapamwamba kwambiri kuti musinthe ziwalo zakale zamagalimoto, kukhulupirika kwa miyeso yanu sikuyamba ndi probe kapena laser, koma ndi zomwe zili pansi pake: maziko a makina. Ku ZHHIMG, takhala tikukhulupirira kwa nthawi yayitali kuti palibe njira yoyezera zinthu yomwe ingapambane maziko ake. Ndipo pankhani yopereka kulondola koona komanso kobwerezabwereza—makamaka m'malo osinthika amafakitale—pali chinthu chimodzi chokha chomwe chimakwaniritsa zosowa za makina owonera ndi ogwira: granite yolondola.
Granite si yachikhalidwe chokha; ndi yabwino kwambiri pa metrology. Mosiyana ndi maziko achitsulo kapena a polima omwe amakula, kufupika, kapena kumveka bwino chifukwa cha kutentha kapena kupsinjika kwa makina, granite yachilengedwe imapereka kukula kwa kutentha pafupifupi zero, kugwedezeka kwapadera, komanso kukhazikika kwa nthawi yayitali. Izi si zonena zamalonda - ndi zinthu zakuthupi zochokera ku geology. Kuti muyeze bwino.makina a granite oyambira makina, izi zikutanthauza kuti njira yowunikira momwe miyeso yonse imachitikira siinasinthe kwenikweni pakasinthasintha, nyengo, komanso zaka zambiri zogwiritsidwa ntchito.
Koma n’chifukwa chiyani izi zili zofunika kwambiri masiku ano? Chifukwa chakuti metrology yamakono ikulumikizana. Mzere pakati pa ma CMM ogwira ntchito ndi ma scanner a 3D osakhudzana ukusokonekera. Makina osakanikirana tsopano amaphatikiza ma touch-trigger probes ndi ma scanner opangidwa mwadongosolo kapena a laser kuti ajambule ma datum a geometric ndi malo ovuta a freeform mu dongosolo limodzi. Komabe kuphatikiza kumeneku kumabweretsa mavuto atsopano: ma sensor optical amakhudzidwa kwambiri ndi kugwedezeka kwa micro- ndi kutentha. Maziko omwe "amamveka" okhazikika m'maso mwa munthu akhoza kuyambitsa kugwedezeka kokwanira kuti asokoneze deta ya scan kapena kusuntha mitambo ya point ndi ma micron angapo - okwanira kuti athetse ma callout a tight GD & T.
Apa ndi pomwe granite yolondola ya nsanja za 3D scanner imakhala yosatheka kukambirana. Ku ZHHIMG, sitikonzanso ma slabs wamba.maziko a graniteMa system optical scanning apangidwa kuchokera ku ma diabase opangidwa bwino, otsika-porisity ochokera ku migodi yovomerezeka ku Scandinavia ndi North America—osankhidwa makamaka kuti akhale ndi kachulukidwe kofanana komanso kukhala ndi homogeneity yamkati. Ma block awa amakalamba mwachilengedwe kwa miyezi 12-24 asanalowe molondola mpaka kulekerera kwa flatness mkati mwa ma microns 2-3 pa nthawi yoposa mamita 3. Pokhapokha pamene malo olumikizirana, malo oyambira, ndi njira zoyendetsera chingwe zimagwirizanitsidwa—popanda kusokoneza kupitiriza kwa kapangidwe ka mwalawo.
Zotsatira zake? Nsanja yokhazikika kwambiri kotero kuti ngakhale masensa osunthika a sub-micron amazindikira kusuntha kochepa panthawi yopanga kwa maola 8. Mmodzi mwa makasitomala athu aku Europe omwe amagwira ntchito yopangira zida za semiconductor posachedwapa adasintha tebulo la optical la carbon-fiber ndi maziko a granite a ZHHIMG kuti agwiritse ntchito scanner yawo ya buluu yothamanga kwambiri. Zotsatira zake? Kubwerezabwereza kwa scan kunakula kuchokera ku ±8 µm kufika ku ±2.1 µm—osati chifukwa scanner inasintha, koma chifukwa maziko anasiya "kupuma" chifukwa cha kusintha kwa kutentha kwa mlengalenga.
Ndipo sizokhudza ma scanner okha. Kwa mafakitale omwe amadalira ZIPANGIZO ZOYERA ZOPANDA KUYERA—monga ma CMM opingasa omwe amagwiritsidwa ntchito poyang'anira thupi loyera kapena ma valvu akuluakulu amafuta ndi gasi—kufunikira kwa maziko kumakhala kwakukulu kwambiri. Mapangidwe opingasa mwachibadwa amapanga katundu wopindika womwe umakulitsa kusinthasintha kulikonse mu kapangidwe kothandizira. Cholumikizira chachitsulo chingatembenuke moonekera pansi pa mphamvu ya probe; ngakhale pansi pa konkire yolimba imatha kufalitsa kugwedezeka kwa nyumba. Granite, yokhala ndi mphamvu yopondereza kwambiri (nthawi zambiri >250 MPa) ndi chiŵerengero cha damping chamkati cha 3–5× kuposa chitsulo choponyedwa, imathetsa zotsatira izi pa gwero.
Ichi ndichifukwa chake tapanga granite yapadera yolondola kwambiri ya ZIPANGIZO ZOYERA ZOPANDA KUGONJETSA zomwe zimapitirira kusalala. Maziko athu a manja opingasa ali ndi zomangira za kinematic zolumikizidwa, ma rail a datum omwe ali ofanana bwino, komanso zotchingira kutentha zomwe zingasinthidwe - zonse zimayesedwa motsatira miyezo ya ISO 10360. Mu kafukufuku waposachedwa wotsimikizira ndi wogulitsa magalimoto wa Tier-1, kampani yathu ya Tier-1 yapanga izi.CMM yopingasa yochokera ku graniteadasunga kulondola kwa voliyumu ya ±(2.8 + L/250) µm kudutsa envelopu ya mamita 6, zomwe zidapambana makina opikisana okhala ndi chimango chachitsulo ndi 37% m'mayeso obwerezabwereza a nthawi yayitali.
Mozama, ZHHIMG imaona nsanja iliyonse ya metrology ngati dongosolo lonse—osati gulu la zigawo. Maziko a makina a granite oyezera ma coordinate si lingaliro loti lizingomangidwa ku chimango; ndi chimango. Njira zonse zoyendetsera, ma bearing, ndi masikelo olembera amatchulidwa mwachindunji pamwamba pa granite panthawi yomaliza, kuchotsa zolakwika zochulukirapo kuchokera ku zigawo zapakati zoyikira. Njirayi imachepetsa nthawi yokhazikitsa, imapangitsa kuti calibration ikhale yosavuta, ndipo—chofunika kwambiri—imaonetsetsa kuti deta yogwira ndi yowunikira imakhala pamalo omwewo enieni a coordinate.
Timakananso njira zazifupi. Opanga ena amagwiritsa ntchito miyala yokonzedwanso kapena epoxy-granite blends kuti achepetse mtengo ndi kulemera. Ngakhale kuti ndizovomerezeka kugwiritsa ntchito zinthu zopepuka, zinthuzi sizimakhala ndi kukhazikika kwa nthawi yayitali kofunikira pa metrology yovomerezeka. Ku ZHHIMG, maziko aliwonse amaperekedwa ndi satifiketi yonse ya zinthu—kuphatikizapo kuchulukana, porosity, thermal expansion coefficient, ndi mapu a flatness—kotero mainjiniya abwino amatha kutsimikizira kuti zinthuzo zikutsatira miyezo yapadziko lonse lapansi.
Kudzipereka kwathu kwatipangitsa kukhala ndi mbiri yabwino pakati pa atsogoleri mu ndege, kupanga zida zamankhwala, komanso kupanga magalimoto amagetsi. Wopanga mabatire a EV ku US posachedwapa adatumiza malo osiyanasiyana osakanikirana a granite ochokera ku ZHHIMG kuphatikiza ma touch probe ndi ma scanner a 3D kuti ayang'ane kulumikizana kwa maselo m'mafakitale akuluakulu. Mwa kuyika mitundu yonse iwiri ya masensa ku datum yofanana ya granite yomwe siigwira kutentha, adapeza kulumikizana kwa cross-validation mkati mwa 3 µm - chinthu chomwe kale chinkaonedwa kuti n'chosatheka pa matebulo ophatikizika.
Kuphatikiza apo, kukhazikika kwa zinthu kumayikidwa mu lingaliro ili. Granite ndi yachilengedwe 100%, imatha kubwezeretsedwanso kwathunthu, ndipo sifunikira zokutira kapena kukonza kupatula kuyeretsa nthawi zonse. Mosiyana ndi mafelemu achitsulo opakidwa utoto omwe amadula kapena kuwononga, chosamalidwa bwinomaziko a graniteZimakula bwino ndi ukalamba, ndipo zimakhala zosalala pogwiritsa ntchito pang'onopang'ono. Zambiri mwa zinthu zomwe timayika kuyambira kumayambiriro kwa zaka za m'ma 2000 zimagwirabe ntchito tsiku ndi tsiku popanda kuwonongeka kwa magwiridwe antchito—umboni wa kufunika kwa zinthuzo kwamuyaya.
Kotero pamene mukuyang'ana ndalama zomwe mukugwiritsa ntchito poyesa zinthu, dzifunseni kuti: kodi makina anu amakono akhazikika pa maziko opangidwa kuti akhale oona—kapena osavuta kugwiritsa ntchito? Ngati ma scan anu a 3D akuwonetsa phokoso losadziwika bwino, ngati CMM yanu ikufunika kukonzedwanso pafupipafupi, kapena ngati bajeti yanu yosatsimikizika yoyezera ikupitiriza kukula, choyambitsa sichingakhale m'ma sensor anu, koma m'chimene chimawathandiza.
Ku ZHHIMG, tikuyitana akatswiri a za metrology ku North America, Europe, ndi Asia-Pacific kuti adzaone kusiyana komwe maziko enieni a granite amapanga.www.zhhimg.comkufufuza zochitika zenizeni, kutsitsa mapepala oyera aukadaulo okhudza njira zosankhira miyala ya granite, kapena kukonza nthawi yowonetsera nsanja zathu zolumikizidwa. Chifukwa poyesa molondola, palibe zonyenga - koma maziko olimba.
