Kwihlabathi elinzima lobunjineli bokuchaneka, umahluko phakathi kokuphumelela kwemveliso kunye neqela lezinto ezilahliweyo ezibizayo udla ngokuhla uye kwi-microns ezimbalwa. Kwiinjineli kunye neengcali zokuqinisekisa umgangatho, ukuthembeka kwendawo yokulinganisa kubaluleke kakhulu. Le ndawo yakhelwe kwizixhobo ezisisiseko: ipleyiti yomphezulu, umda othe tye, kunye nezibonakaliso zokuchaneka eziqinisekisa inyaniso yejometri. Kwi-ZHHIMG, siyaqonda ukuba ukukhetha izinto ezifanelekileyo kunye nesixhobo asikokukhetha nje kuphela, kodwa kukubalwa okubalulekileyo kwe-thermal dynamics kunye nesayensi yezinto.
I-Granite vs. Intsimbi: Imfazwe yeSiseko
Eyona ngxoxo iphambili ekusekweni kwelebhu ye-metrology kukukhetha phakathi kwegranite kunye neepleyiti zomphezulu wentsimbi. Kangangamashumi eminyaka, isinyithi esityhidiweyo kunye nentsimbi yayiziimigangatho zoshishino. Nangona kunjalo, ukutshintshela kwigranite kuqhutywa ziimpawu zomzimba zendalo zezinto.
Inzuzo ephambili yegranite kunentsimbi kukuzinza kwayo okuphezulu kobushushu. Intsimbi inomlinganiselo ophezulu wokwanda kobushushu, oko kuthetha ukuba nokuguquguquka okuncinci kubushushu begumbi kunokubangela ukuba ipleyiti yande okanye inciphe, nto leyo ephazamisa umgca wesalathiso. Igranite, ngakumbi igranite emnyama enoxinano oluphezulu esetyenziswa yiZHHIMG, inomlinganiselo ophantsi kakhulu. Oku kuqinisekisa ukuba "inqaku le-zero" lihlala lihambelana kulo lonke ixesha lomsebenzi.
Ngaphezu koko, igranite ngokwemvelo ayinamagnethi kwaye ayitshisi umhlwa. Kwimeko yokusebenzela apho ukufuma okanye ukuphazamiseka kwemagnethi kwizixhobo zombane kunokonakalisa izixhobo zentsimbi, igranite ihlala ingasebenzi. Mhlawumbi okona kubaluleke kakhulu ukuze ihlale ixesha elide, ukubaumphezulu wegraniteUkuba itshixiwe ngempazamo, ayidali “i-burr.” Ngokwahlukileyo koko, ukuqhekeka kwipleyiti yentsimbi kutyhala izinto phezulu, kudala indawo ephakamileyo eyonakalisa ukuthe tyaba komphezulu wonke. Ngegranite, itshiphu ibangela umngxuma omncinci ongawuchaphazeliyo ukuthe tyaba okujikelezileyo.
Indima yeSibonisi sokuDial ekuQinisekisweni koMphezulu
Nje ukuba isiseko esizinzileyo simiselwe, isalathisi sedayali siba sisixhobo esiphambili sokunxibelelana nengcali ngenyani yejometri yenxalenye. Nokuba kusetyenziswa isalathisi sovavanyo sohlobo lwe-plunger okanye sohlobo lwe-lever, ezi zixhobo “zingamehlo” engcali yemetro.
Intsebenziswano phakathi kweipleyiti yomphezulu wegranitekwaye isalathisi sedayili sibonakala kakuhle ngexesha lokujonga ukuba tyaba kunye nokuhambelana. Ngokufaka isalathisi kwindawo ezinzileyo—edla ngokuba nesiseko sedayili ngokwayo ukuze ihambelane neprofayili yobushushu yepleyiti—iinjineli zinokutshayela kwindawo yokusebenza ukuze zibone ukuphambuka. Uvakalelo lwezalathisi zedijithali zanamhlanje, ezidla ngokufikelela kumanqanaba angama-0.001mm, lufuna umphezulu wokufakelwa ongenangcangcazelo. Iimpawu zendalo zokudambisa idayili zifunxa ukungcangcazela komgangatho okuqhelekileyo okuya kubangela ukuba "kuqhawuke" kwisalathisi sedayili esinovakalelo.
Iintlobo zeeMphetho eziQondileyo ezichanekileyo kunye nezicelo zazo
Nangona iipleyiti zomphezulu zibonelela ngeplani yesalathiso se-2D, umda othe tye ngokuchaneka ubalulekile ekuhlolweni komgca we-1D. Ayizizo zonke ii-edges ezithe tye ezenzelwe umsebenzi ofanayo, kwaye ukuqonda iintlobo ezikhoyo kubalulekile ekugcineni ukuchaneka komgangatho wevenkile.
Imiphetho ethe tye yegranite ekumgangatho welebhu yeyona ndlela ilungileyo yokujonga ulungelelwaniso lweendlela zezixhobo zomatshini. Ngenxa yokuba zigqitywe kumacala amabini okanye amane ukuya kumacala ahambelanayo, zivumela ukujonga ngaxeshanye kweendawo ezininzi.
Imiphetho ethe tye yentsimbi, ingakumbi i-"I-Beam" okanye iintlobo ezimile okwesaphetha, zisasetyenziswa ngenxa yomlinganiselo wazo ophezulu wokuqina-ukuya-kubunzima kwizicelo eziphathwayo. Nangona kunjalo, ukulinganisa okungaguqukiyo kweendlela zesikhokelo ze-CNC, i-granite iyathandwa ngenxa yobunzima bayo, obuyinceda "ihlale" ngokuqinileyo kumphezulu ovavanywayo, ukuthintela ukushukuma okuncinci okunokwenzeka ngeenguqulelo ze-aluminium okanye zentsimbi ezikhaphukhaphu.
Kukwakho nemiphetho ethe tye ekhethekileyo "engunxantathu". Ezi zenzelwe ngokukodwa ukujonga ubume besikwere be-90-degree yee-axes zomatshini. Xa zidityaniswe nesalathisi sokudayela esinesisombululo esiphezulu, isikwere segranite okanye umphetho othe tye ongunxantathu unokubonisa "iimpazamo zejiyometri" ezingabonakaliyo ekuhambeni komatshini ezinokuthi zingajongwa yi-interferometer yelaser eqhelekileyo ngexesha lokuhamba okulula.
Izixhobo ezibalulekileyo zeMetrology kwiVenkile yanamhlanje
Ngaphaya kweepleyiti kunye nemiphetho, i-metrology suite epheleleyo ifuna indlela epheleleyo yokulinganisa. Oku kuquka iityhubhu zegranite ezichanekileyo, ii-parallels, kunye nee-V-blocks. Injongo kukudala "i-closed-loop" yokuchaneka apho zonke izixhobo ezisetyenziselwa ukubamba okanye ukulinganisa inxalenye zineempawu ezifanayo zokwandiswa kobushushu.
Kwimizi-mveliso yeenqwelo-moya kunye neye-semiconductor, apho izinto zihlala zingenazo ii-ferrous, uhlobo lwe-ZHHIMG granite olungenazo ii-conductive kunye nolwe-non-magnetic lubonelela ngendawo yokuvavanya engathathi cala. Xa kuhlanganiswa izixhobo ze-metrology, umntu kufuneka aqwalasele "uMgaqo we-Abbe," oyalela ukuba isikali sokulinganisa ukufuduka kufuneka sibe kumgca othe tye kunye nomlinganiselo osebenzayo olinganiswayo. Ukusebenzisa izakhiwo ze-granite ezichanekileyo kakhulu njengezindlu zezi zikali zokulinganisa kunciphisa "iimpazamo ze-sine" zokwenza izixhobo xa ziguquguquka phantsi kobunzima bazo.
Ukugcinwa kunye nobude bexesha lezixhobo ezichanekileyo
Ukutyala imali kwizixhobo ze-metrology ze-premium licebo lexesha elide. Ukugcina ukuchaneka kwepleyiti yomphezulu we-granite okanye umda othe tye ochanekileyo, ukulinganiswa rhoqo akunakuxoxiswana ngako. Ekuhambeni kwexesha, ne-granite enzima kakhulu inokubonisa iimpawu zokuguguleka "kwiindawo ezishushu" apho iindawo zihlala zilayishwa khona.
Sicebisa indlela ecwangcisiweyo: ukucoca imihla ngemihla kunyeipleyiti yomphezulu ekhethekileyoabacoci bokususa uthuli kunye neeoyile, kunye nokulungiswa komphezulu wobungcali rhoqo ngonyaka. Kwizalathisi zedayile, ukuqinisekisa ukuba iindawo zokunxibelelana azinazo inkunkuma kwaye iindlela zangaphakathi zilinganiswe kwiibhloko zegeyiji eziqinisekisiweyo kuya kuqinisekisa ukuba ukufundwa okubonayo kukufundwa onokukuthemba.
Apha kwi-ZHHIMG, sikholelwa ukuba ukuchaneka yinkcubeko, kungekuphela nje ukulinganisa. Ngokuqonda isayensi yezinto ezibonakalayo zegranite ngokuchasene nentsimbi kunye nokukhetha imiphetho ethe tye kunye nezalathisi ezifanelekileyo zesicelo sakho esithile, ubeka isiseko sokugqwesa kwimveliso. Nokuba ufaka ilebhu entsha yokulinganisa okanye uphucula umgca wemveliso, isiseko osikhethayo namhlanje siya kumisela ukunyamezela onokukufezekisa ngomso.
