Ezweni lokukhiqiza ubuchwepheshe obuphezulu, lapho ubukhulu bezici buncipha khona endaweni ye-nanometer, ukuthembeka kokulawula ikhwalithi kuncike ngokuphelele ekunembeni nasekuzinzeni kwezinsimbi zokulinganisa. Ngokukhethekile, Imishini Yokulinganisa Ububanzi Bomugqa Ozenzakalelayo—ithuluzi eliyinhloko ekukhiqizweni kwe-semiconductor, microelectronics, kanye nokuboniswa kwephaneli eyisicaba—kumele isebenze ngokwethembeka okuphelele. Ngenkathi ama-optics athuthukile kanye nama-algorithms esivinini esiphezulu enza ukulinganisa okusebenzayo, isisekelo esingenzi lutho, kodwa esibucayi, esakhiweni esinquma uphahla lokusebenza oluphelele lwesistimu. Lesi sisekelo ngokuvamile siyimishini yokulinganisa ububanzi bomugqa Ozenzakalelayo.isisekelo somshini we-granitekanye nokuhlanganiswa kwayo kwe-granite okuhambisanayo kwemishini yokulinganisa ububanzi bomugqa ozenzakalelayo.
Ukukhetha izinto zokwakha akuyona isinqumo esincane; kuyisibopho sobunjiniyela. Ezinqumweni eziqine kakhulu ezidingekayo ekulinganisweni kobubanzi bomugqa, izici zemvelo ezinganakwa empilweni yansuku zonke ziba yimithombo yamaphutha enhlekelele. Izinto ezifana nokukhukhuleka kokushisa, ukudlidliza kwe-ambient, kanye nokuqhekeka kwesakhiwo kungasunduza kalula izilinganiso ngaphandle kokubekezelelana okwamukelekayo. Le nselele yingakho onjiniyela bokunemba bephendukela kakhulu ku-granite yemvelo ukwakha izingxenye ezibaluleke kakhulu zemishini yabo ye-metrology.
I-Physics of Precision: Kungani I-Granite Ishaya Insimbi
Ukuze uqonde isidingo sesisekelo somshini we-granite wokulinganisa ububanzi bomugqa ozenzakalelayo, umuntu kufanele aqonde i-physics elawula ukulinganisa okunembe kakhulu. Ukunemba kuwumsebenzi wokuqina kohlaka lokubhekisela. Isisekelo kumele siqinisekise ukuthi indawo ehlobene phakathi kwenzwa (ikhamera, i-laser, noma i-probe) kanye nesampula ihlala izinzile ngesikhathi senqubo yokulinganisa, ngokuvamile ihlala ama-millisecond kuphela.
1. Ukuzinza Kokushisa Kubaluleke Kakhulu: Izinsimbi ezifana nensimbi ne-aluminium zingabaqondisi bokushisa abaphumelelayo futhi zine-Coefficients of Thermal Expansion (CTE) ephezulu kakhulu. Lokhu kusho ukuthi zishisa ngokushesha, ziphole ngokushesha, futhi zishintsha kakhulu ngokushintshashintsha kwezinga lokushisa okuncane. Ukushintsha kwamadigri ambalwa nje kungaholela ezinguqukweni zobukhulu esakhiweni sensimbi ezidlula kakhulu isabelomali samaphutha esivunyelwe sokulinganisa i-sub-micron.
I-Granite, ikakhulukazi i-granite emnyama esezingeni eliphezulu, inikeza ikhambi elingcono kakhulu. I-CTE yayo iphansi ngokuphindwe kahlanu kuya kweshumi kuneyezinsimbi ezivamile. Leli zinga eliphansi lokunwebeka lisho ukuthi i-Automatic line measuring width equipment granite assembly igcina ubuqotho bayo bejometri ngisho nalapho amazinga okushisa efektri eshintshashintsha kancane noma lapho izingxenye zangaphakathi zikhiqiza ukushisa. Lokhu kushisa okungavamile kunikeza ukuzinza kwesikhathi eside okubalulekile ekulinganisweni kwe-metro okuphindaphindwayo nokuthembekile, usuku nosuku.
2. Ukudambisa Ukudlidliza Ukuze Kucace: Ukudlidliza, kungakhathaliseki ukuthi kudluliswa phansi efektri noma kukhiqizwa yizigaba zokunyakaza zomshini kanye nabalandeli bokupholisa, kuyisitha sokuthwebula izithombe nokubeka endaweni enesinqumo esiphezulu. Uma ikhanda lokulinganisa noma isiteji sidlidliza ngesikhathi sokuthwebula okubonakalayo, isithombe sizofiphala, futhi idatha yendawo izophazamiseka.
Isakhiwo sangaphakathi sekristalu seGranite sinikeza izakhiwo zokudambisa ezingcono kakhulu uma kuqhathaniswa nensimbi ephonswe noma insimbi. Simunca futhi siqede amandla omshini ngokushesha, sivimbele ukudlidliza ukuthi kungasabalali esakhiweni futhi kuphazamise ukulinganisa. Lesi sici sokudambisa okuphezulu sivumela isisekelo segranite semishini yokulinganisa ububanzi bomugqa ozenzakalelayo ukuthi sinikeze ipulatifomu ethule, ezinzile, evumela ukuphuma okusheshayo ngenkathi igcina amazinga okunemba aqinile.
Ukwakha Umhlangano We-Granite: Ngale Kwe-Block Nje
Ukusetshenziswa kwe-granite kudlulela ngale kwepulatifomu elula; kuhlanganisa yonke i-Automatic line measuring width equipment granite assembly. Lokhu kuvame ukufaka isisekelo somshini, amakholomu aqondile, futhi, kwezinye izimo, izakhiwo zebhuloho noma ze-gantry. Lezi zingxenye aziwona nje amatshe asikiwe; ziyizingxenye ezakhiwe kahle kakhulu, ezinemininingwane eminingi.
Ukufeza Ukuthamba Okungaphansi Kwe-Micron: Inqubo yokuguqula i-granite eluhlaza ibe yingxenye yezinga le-metrology iyikhono nesayensi. Izinto zokwakha zisetshenziswa amasu okugaya, ukugoqa, kanye nokupholisha akhethekile angafinyelela ukuthamba komphezulu kanye nokubekezelelana kokuqonda okulinganiswe ngama-fraction e-micrometer. Lo mphezulu othamba kakhulu ubalulekile ezinhlelweni zokulawula ukunyakaza zanamuhla, njengezigaba ezithwala umoya, ezintanta emoyeni omncane futhi ezidinga umphezulu oqondile ocishe ufane ukuze kufezwe ukunyakaza okungenamikhuhlane, okunembe kakhulu.
Ukuqina kwesisekelo esikhulu somshini wokulinganisa ububanzi bomugqa ozenzakalelayo kungenye into engaxoxiswana ngayo. Ukuqina kuqinisekisa ukuthi isakhiwo simelana nokuphambuka ngaphansi kwamandla ashukumisayo ama-motor aqondile anejubane eliphezulu kanye nesisindo sephakheji ye-optics. Noma yikuphi ukuphambuka okulinganiselwe kuzoletha amaphutha ejiyometri, njengokungabi yisikwele phakathi kwama-axes, okungathinta ngqo ukunemba kokulinganisa.
Ukuhlanganiswa kanye Nenani Lesikhathi Eside
Isinqumo sokusebenzisa isisekelo se-granite siwukutshalwa kwezimali okukhulu kwesikhathi eside ekusebenzeni kwemishini kanye nokuphila kwayo isikhathi eside. Umshini oqiniswe yi-granite base eqinile yokulinganisa ububanzi bomugqa ozenzakalelayo awuthambekeli kakhulu ekuxazululeni izinkinga ngokuhamba kwesikhathi futhi ugcina i-geometry yawo elinganiswe efektri iminyaka eminingi, kunciphisa imvamisa kanye nobunzima bemijikelezo yokulinganisa kabusha.
Ekuhlanganisweni okuthuthukisiwe, izingxenye zokuqondanisa ngokunemba, njengezifakelo ezinezintambo, izikhonkwane ze-dowel, kanye nemigqa yokuthwala eqondile, kumele zifakwe epoxini esakhiweni se-granite. Le nqubo idinga amasu okubopha ochwepheshe ukuqinisekisa ukuthi ukuxhumana phakathi kwensimbi ne-granite kugcina ukuzinza kwezinto futhi akulethi ukucindezeleka kwendawo noma ukungalingani kokushisa. Ngakho-ke, i-Automatic line width measuring granite assembly iba isakhiwo esisodwa, esihlanganisiwe esenzelwe ukuqina okuphezulu kanye nokuvikeleka kwemvelo.
Njengoba abakhiqizi befuna isivuno esiphezulu kanye nemininingwane eqinile—edinga ukunemba kokulinganisa ukuze kufane nekhono lokukhiqiza—ukuthembela ezimpahleni zangaphakathi ze-granite kuzojula kakhulu. Imishini Yokulinganisa Ububanzi Bomugqa Ozenzakalelayo imelela isiqongo se-metrology yezimboni, futhi isisekelo sayo sokuqina, isisekelo se-granite, sihlala singumqaphi othule oqinisekisa ukuthi yonke imilinganiselo ethathwayo iyisibonakaliso seqiniso nenembile sekhwalithi yomkhiqizo. Ukutshalwa kwezimali esisekelweni se-granite sekhwalithi ephezulu, kalula nje, kuwukutshalwa kwezimali ekuqinisekisweni okuphelele kokulinganisa.
