Emkhakheni we-precision optics kanye ne-metrology, ukufeza indawo ezinzile nengenazo izithingithingi kuyisisekelo sokulinganisa okuthembekile. Phakathi kwazo zonke izinhlelo zokusekela ezisetshenziswa emalabhorethri nasezindaweni zezimboni, ipulatifomu entantayo yomoya obonakalayo—eyaziwa nangokuthi ithebula lokuhlukanisa izithingithingi—idlala indima ebalulekile ekuqinisekiseni ukunemba okuphezulu kwezinsimbi ezifana nama-interferometer, izinhlelo ze-laser, kanye nemishini yokulinganisa edidiyelwe (ama-CMM).
Ukwakheka Kobunjiniyela bePlatform Yokukhanya
Ipulatifomu yokukhanya esezingeni eliphezulu inesakhiwo se-honeycomb esivalwe ngokuphelele, esenzelwe ukuqina okumangalisayo nokuzinza kokushisa. Amapuleti aphezulu naphansi, ngokuvamile angu-5 mm ubukhulu, ahlanganiswe nengqikithi ye-honeycomb eyenziwe ngomshini oqondile eyenziwe ngamashidi ensimbi angu-0.25 mm, akha isakhiwo esilinganayo nesiyi-isotropic. Lo mklamo unciphisa ukwanda nokuncipha kokushisa, okuqinisekisa ukuthi ipulatifomu igcina isicaba sayo ngisho nokushintshashintsha kwezinga lokushisa.
Ngokungafani ne-aluminium noma i-composite cores, isakhiwo se-honeycomb sensimbi sinikeza ukuqina okuqhubekayo kulo lonke ukujula kwaso, ngaphandle kokuletha ukuguqulwa okungafuneki. Izindonga eziseceleni nazo zenziwe ngensimbi, okuqeda ngempumelelo ukungazinzi okuhlobene nomswakama—inkinga evame ukubonwa ezisekelweni ezenziwe ngezinto ezixubile. Ngemva kokuphothulwa ngokuzenzakalela kwendawo nokupholisha, i-tabletop ifinyelela ukuthamba kwe-sub-micron, okunikeza indawo efanelekile yokuhlangana kwe-optical kanye nezinsimbi zokunemba.
Ukulinganisa Ngokunembile Nokuhlolwa Kokuhambisana
Ngaphambi kokushiya ifektri, ipulatifomu ngayinye entantayo yomoya obonakalayo idlula ochungechungeni lokuhlolwa kokudlidliza nokuhambisana nomthetho. Isando sokushaya kwenhliziyo sisebenzisa amandla alawulwayo ebusweni bepulatifomu kuyilapho izinzwa ziqopha impendulo yokudlidliza ephumayo. Izimpawu ziyahlaziywa ukuze kukhiqizwe i-frequency response spectrum, esiza ekunqumeni ukusebenza kwepulatifomu kokuzwakala kanye nokusebenza kokuhlukaniswa kwayo.
Izilinganiso ezibaluleke kakhulu zithathwa kusukela emagumbini amane epulatifomu, njengoba la maphuzu amelela isimo sokuthobela imithetho esibi kakhulu. Umkhiqizo ngamunye unikezwa umugqa wokuthobela imithetho ozinikele kanye nombiko wokusebenza, okuqinisekisa ukucaca okugcwele kwezimpawu eziguquguqukayo zepulatifomu. Leli zinga lokuhlola lidlula imikhuba yendabuko yemboni, okunikeza abasebenzisi ukuqonda okuningiliziwe kokuziphatha kwepulatifomu ngaphansi kwezimo zangempela zokusebenza.
Indima Yokuhlukaniswa Kokudlidliza
Ukuhlukaniswa kokudlidliza kuyisisekelo somklamo weplatifomu yokukhanya. Ukudlidliza kuvela emithonjeni emibili eyinhloko—yangaphandle neyangaphakathi. Ukudlidliza kwangaphandle kuvela emhlabathini, njengezinyathelo, imishini eseduze, noma ukuzwakala kwesakhiwo, kuyilapho ukudlidliza kwangaphakathi kuvela ekugelezeni komoya, izinhlelo zokupholisa, kanye nokusebenza kwethuluzi ngokwalo.
Ipulatifomu yokukhanya entantayo emoyeni ihlukanisa zombili izinhlobo. Imilenze yayo yokumisa umoya imunca futhi inciphise ukudlidliza kwangaphandle okudluliselwa phansi, kuyilapho ungqimba lomswakama oluthwala umoya ngaphansi kwetafula luhlunga umsindo wangaphakathi womshini. Ndawonye, zakha isisekelo esithule nesizinzile esiqinisekisa ukunemba kokulinganisa okunembe kakhulu kanye nokuhlolwa.
Ukuqonda Imvamisa Yemvelo
Zonke izinhlelo zemishini zinemvamisa yemvelo—imvamisa lapho zivame ukudlidliza khona uma ziphazamiseka. Le pharamitha ihlobene eduze nobunzima kanye nokuqina kwesistimu. Ezinhlelweni zokuhlukanisa i-optical, ukugcina imvamisa yemvelo ephansi (ngokuvamile engaphansi kuka-2–3 Hz) kubalulekile, njengoba kuvumela ithebula ukuthi lihlukanise ukudlidliza kwemvelo ngempumelelo kunokukukhulisa. Ibhalansi phakathi kobukhulu, ukuqina, kanye nokuncibilikisa i-damping inquma ngqo ukusebenza kahle kanye nokuzinza kokuhlukanisa kwesistimu.
Ubuchwepheshe Beplatifomu Entantayo Yomoya
Amapulatifomu esimanje antantayo emoyeni angahlukaniswa ngezigaba ze-XYZ eziqondile zokuthwala umoya kanye namapulatifomu ajikelezayo okuthwala umoya. Ingqikithi yalezi zinhlelo yindlela yokuthwala umoya, enikeza ukunyakaza okungenazingxabano okusekelwa ifilimu encane yomoya ocindezelwe. Kuye ngokusetshenziswa, ama-air bearings angaba yizinhlobo eziyisicaba, eziqondile, noma eziyisipinashi.
Uma kuqhathaniswa neziqondiso eziqondile zemishini, ama-air bearings anikeza ukunemba kokunyakaza kwezinga le-micron, ukuphindaphindeka okumangalisayo, kanye nokungagugi kwemishini. Asetshenziswa kabanzi ekuhlolweni kwe-semiconductor, i-photonics, kanye nezinhlelo zokusebenza ze-nanotechnology, lapho ukunemba kwe-sub-micron kanye nokuzinza kwesikhathi eside kubalulekile.
Ukugcinwa Nokuphila Isikhathi Eside
Ukugcina ipulatifomu yokuntanta yomoya obonakalayo kulula kodwa kubalulekile. Gcina indawo ihlanzekile futhi ingenazo izinsalela, hlola njalo umoya ukuthi awutholi yini umswakama noma ukungcola, futhi ugweme umthelela omkhulu etafuleni. Uma inakekelwa kahle, itafula elibonakalayo elinembile lingasebenza ngokuthembekile amashumi eminyaka ngaphandle kokonakala kokusebenza.
