Kwihlabathi lemveliso yobuchwepheshe obuphezulu, apho ubukhulu beempawu buncipha ukuya kwinqanaba le-nanometer, ukuthembeka kolawulo lomgangatho kuxhomekeke ngokupheleleyo ekuchanekeni nasekuzinzeni kwezixhobo zokulinganisa. Ngokukodwa, Izixhobo Zokulinganisa Ububanzi Bomgca Ozenzekelayo—isixhobo selitye eliyisiseko kwi-semiconductor, microelectronics, kunye nemveliso yokubonisa iphaneli ethe tyaba—kufuneka zisebenze ngokuthembeka okupheleleyo. Ngelixa ii-optics eziphambili kunye nee-algorithms zesantya esiphezulu zenza umlinganiselo osebenzayo, sisiseko esingasebenziyo, kodwa esibalulekileyo, solwakhiwo esilawula umgangatho wokusebenza wenkqubo. Esi siseko sidla ngokuba sisixhobo sokulinganisa ububanzi bomgca Ozenzekelayo.isiseko somatshini wegranitekunye nendibano yayo yegranite yokulinganisa ububanzi bomgca ozenzekelayo.
Ukukhetha izinto zokwakha akusosigqibo silula; ngumyalelo wobunjineli. Kwiisisombululo ezigqithisileyo ezifunekayo ekulinganisweni kobubanzi bomgca, izinto ezingqongileyo ezingabalulekanga kubomi bemihla ngemihla ziba yimithombo emibi yempazamo. Izinto ezifana nokushukuma kobushushu, ukungcangcazela kwendalo, kunye nokuqhekeka kwesakhiwo zinokususa ngokulula imilinganiselo ngaphandle kokunyamezelana okwamkelekileyo. Lo ngumngeni obangela ukuba iinjineli zokuchaneka ziguqukele kakhulu kwi-granite yendalo ukwakha ezona zinto zibalulekileyo kwizixhobo zazo ze-metrology.
Ifiziksi Yokuchaneka: Kutheni iGranite Ithetha Ngesinyithi
Ukuze uqonde imfuneko yesiseko somatshini wegranite wokulinganisa ububanzi bomgca ozenzekelayo, umntu kufuneka ayiqonde ifiziksi elawula umlinganiselo ochanekileyo. Ukuchaneka ngumsebenzi wokuzinza kwesakhelo sokubhekisa. Isiseko kufuneka siqinisekise ukuba indawo ephakathi kwesensor (ikhamera, i-laser, okanye i-probe) kunye nesampuli ihlala izinzile ngexesha lenkqubo yokulinganisa, ihlala i-milliseconds kuphela.
1. Uzinzo lobushushu lubaluleke kakhulu: Iintsimbi ezifana nentsimbi kunye ne-aluminium zii-thermal conductors ezisebenzayo kwaye zine-Coefficients of Thermal Expansion (CTE) ephezulu. Oku kuthetha ukuba zifudumala ngokukhawuleza, ziphole ngokukhawuleza, kwaye zitshintsha kakhulu ngokwemilinganiselo kunye nokuguquguquka okuncinci kobushushu. Utshintsho lweedigri ezimbalwa nje lunokukhokelela kutshintsho lwemilinganiselo kwisakhiwo sesinyithi oludlula kakhulu ibhajethi yempazamo evumelekileyo yokulinganisa i-sub-micron.
I-Granite, ingakumbi i-granite emnyama ekumgangatho ophezulu, inika isisombululo esigqwesileyo. I-CTE yayo iphantsi ngokuphindwe kahlanu ukuya kwelishumi kuneyeentsimbi eziqhelekileyo. Eli zinga liphantsi lokwandiswa lithetha ukuba i-Automatic line width measuring equipment granite assembly igcina i-geometrical ingqibelelo yayo nokuba amaqondo obushushu asefektri atshintsha kancinci okanye xa izinto zangaphakathi zivelisa ubushushu. Le thermal inertia ingaqhelekanga inika uzinzo lwexesha elide oluyimfuneko kwi-metrology ephindaphindwayo nethembekileyo, imihla ngemihla.
2. Ukudambisa Ukungcangcazela Ukuze Kucace: Ukungcangcazela, nokuba kudluliswa kumgangatho wefektri okanye kuveliswe zizigaba zokuhamba zomatshini kunye neefeni zokupholisa, lutshaba lomfanekiso kunye nokubekwa kwemifanekiso enesisombululo esiphezulu. Ukuba intloko yokulinganisa okanye iqonga liyangcangcazela ngexesha lokubanjwa kwe-optical, umfanekiso uya kufiphala, kwaye idatha yendawo iya konakala.
Isakhiwo sangaphakathi sekristale seGranite sibonelela ngeempawu zokudambisa ezikumgangatho ophezulu xa kuthelekiswa nentsimbi ephosiweyo okanye intsimbi. Sifunxa kwaye sichitha amandla oomatshini ngokukhawuleza, sithintela ukungcangcazela ukuba kungasasazeki kwisakhiwo kwaye kuphazamise umlinganiselo. Le nto yokudambisa ephezulu ivumela isiseko segranite sezixhobo zokulinganisa ububanzi bomgca ozenzekelayo ukuba sinike iqonga elizolileyo nelizinzileyo, elivumela ukusasazeka ngokukhawuleza ngelixa ligcina imigangatho yokuchaneka eqinileyo.
Ubunjineli beNdibano yeGranite: Ngaphaya kweBloko nje
Ukusetyenziswa kwegranite kudlulela ngaphaya kweqonga elilula; kubandakanya yonke indibano yegranite yezixhobo zokulinganisa ububanzi bomgca ozenzekelayo. Oku kudla ngokubandakanya isiseko somatshini, iikholamu ezithe nkqo, kwaye, kwezinye iimeko, izakhiwo zebhulorho okanye zegantry. Ezi zinto azingomatye asikiweyo nje kuphela; zizinto ezakhiwe ngobuchule obuphezulu, ezichanekileyo kakhulu.
Ukufezekisa i-Sub-Micron Flatness: Inkqubo yokuguqula i-granite eluhlaza ibe yinxalenye ye-metrology-grade yinkqubo yobugcisa nesayensi. Le nto isetyenziswa kwiindlela ezikhethekileyo zokusila, ukugoba, kunye nokupolisha ezinokufezekisa ukuqina komphezulu kunye nokunyamezelana kokuqina okulinganiswe ngamaqhezu e-micrometer. Lo mphezulu uthe tyaba kakhulu ubalulekile kwiinkqubo zanamhlanje zokulawula intshukumo, ezifana nezigaba zomoya, ezidada kwifilimu encinci yomoya kwaye zifuna umphezulu ongqindilili ophantse ube mhle ukuze kufezekiswe intshukumo engenakuphikiswana, echanekileyo kakhulu.
Ukuqina kwesiseko somatshini wegranite esikhulu sezixhobo zokulinganisa ububanzi bomgca ozenzekelayo yenye into engenakuphikiswana ngayo. Ukuqina kuqinisekisa ukuba isakhiwo siyamelana nokuphambuka phantsi kwamandla aguqukayo eemoto ezikhawulezayo kunye nobunzima bephakheji ye-optics. Nakuphi na ukuphambuka okunokulinganiswa kuya kungenisa iimpazamo zejometri, ezifana nokungabikho kwesikwere phakathi kwee-axes, okuya kuchaphazela ngokuthe ngqo ukuchaneka kokulinganisa.
Ukuhlanganiswa kunye nexabiso lexesha elide
Isigqibo sokusebenzisa isiseko segranite sityala-mali elikhulu ixesha elide ekusebenzeni kwesixhobo kunye nobude baso. Umatshini oxhonywe sisixhobo sokulinganisa ububanzi bomgca ozenzekelayo oqinileyo awunangxaki yokusombulula iingxaki ngokuhamba kwexesha kwaye ugcina ijiyometri yawo elinganiswe ngumzi-mveliso iminyaka emininzi, nto leyo enciphisa ukuphindaphindeka kunye nobunzima bemijikelo yokulinganisa kwakhona.
Kwindibano ephucukileyo, izinto ezilungelelaniswe ngokuchanekileyo, ezifana nee-threaded inserts, ii-dowel pins, kunye nee-linear bearing rails, kufuneka zifakwe kwisakhiwo se-granite. Le nkqubo ifuna iindlela zobungcali zokubopha ukuqinisekisa ukuba unxibelelwano phakathi kwesixhobo sesinyithi kunye ne-granite lugcina uzinzo lwendalo lwezixhobo kwaye aluzisi uxinzelelo lwendawo okanye ukungalingani kobushushu. Indibano ye-granite yezixhobo zokulinganisa ububanzi bomgca ozenzekelayo ngoko ke iba sisakhiwo esinye, esidibeneyo esenzelwe ukuqina okuphezulu kunye nokukhuselwa kwendalo.
Njengoko abavelisi befuna isivuno esiphezulu kunye neenkcukacha eziqinileyo—ezifuna ukuchaneka kokulinganisa ukuze zihambelane nokukwazi ukwenza—ukuxhomekeka kwiimpawu zoomatshini zegranite kuya kuqhubeka kusanda. Izixhobo Zokulinganisa Ububanzi Bomgca Ozenzekelayo zimele eyona nto iphambili kwi-metrology yemizi-mveliso, kwaye isiseko sazo sozinzo, isiseko segranite, sihlala singumlindi othuleyo oqinisekisa ukuba yonke imilinganiselo ethathiweyo ibonakalisa umgangatho wemveliso ngokuchanekileyo. Utyalo-mali kwisiseko segranite esisemgangathweni ophezulu, ngokulula, lutyalo-mali ekuqinisekiseni ngokupheleleyo umlinganiselo.
