Ezweni elithuthukayo ngokushesha lokukhiqiza okuthuthukile, ukunemba kuhlala kuwumngcele wokugcina. Namuhla, into entsha eqanjiwe isethwe ukuze ichaze kabusha izindinganiso zomkhakha: I-Precision Marble Three-Axis Gantry Platform, isimanga sobunjiniyela esihlanganisa ukuzinza kwemvelo kwegwadle nomklamo womshini osezingeni eliphezulu ukuze kuzuzwe ukunemba kwezinga le-micron ngaphambilini obekucatshangwa ukuthi kungafinyeleleki ezinhlelweni zezimboni.
Isayensi Engemuva Kokuzinza
Enhliziyweni yalokhu kugxuma kobuchwepheshe kukhona ukukhetha okungalindelekile kwempahla: igwadle lemvelo. Isisekelo semabula esenziwe ngomshini wokunemba esingu-1565 x 1420 x 740 mm asisona nje idizayini yobuhle—iyisixazululo sesayensi senselele yakudala yokugcina ukuzinza kumasistimu anembe kakhulu. “I-granite ephansi kakhulu ye-coefficient yokwanda okushisayo (2.5 x 10^-6 /°C) nezici zokumanzisa ezingavamile zinikeza isisekelo esimelana nokushintshashintsha kwezinga lokushisa kwemvelo nokudlidliza kwemishini kangcono kakhulu kunezakhiwo zensimbi ezivamile,” kuchaza uDkt. Emily Chen, unjiniyela oholayo e-Precision Engineering Research Institute.
Le nzuzo yemvelo ihumusha ngokuqondile kumamethrikhi okusebenza ashintshashintshayo kuzo zonke izimboni. Inkundla ifinyelela ukuphindaphinda okungu-±0.8 μm—okusho ukuthi ingabuyela kunoma isiphi isimo ngokuchezuka okuncane kunobude beza beza bokukhanya okubonakalayo—kanye nokunemba kokuma kokuma okungu-±1.2 μm ngemva kwesinxephezelo, ibeka indinganiso entsha yezinhlelo zokulawula ukunyakaza.
Ubunjiniyela obuhle kakhulu ku-Motion
Ngalé kwesisekelo sayo esizinzile, idizayini yeplathifomu ye-axis emithathu ihlanganisa izinto ezintsha zobunikazi ezimbalwa. I-X-axis ihlanganisa isistimu ye-dual-drive eqeda ukuguquguquka kwe-torsional ngesikhathi sokunyakaza kwesivinini esikhulu, kuyilapho zombili izimbazo ze-X kanye ne-Y ziletha u-750 mm wohambo oluphumelelayo ngo-≤8 μm oqondile kuzo zombili izindiza ezivundlile neziqondile. Leli zinga lokunemba kwejometri liqinisekisa ukuthi ngisho nama-trajectories e-3D ayinkimbinkimbi agcina ukunemba kwe-sub-micron.
Amandla okunyakaza esistimu ashaya ibhalansi emangalisayo phakathi kwesivinini nokunemba. Nakuba isivinini sayo esiphezulu esingu-1 mm/s singase sibonakale sinesizotha, sithuthukiselwa izinhlelo zokusebenza ezidinga ukulawula okuhle nokuskena okunensayo—lapho ukunemba kubaluleke ngaphezu kokunyakaza okusheshayo. Ngokuphambene, ikhono lokusheshisa le-2 G liqinisekisa ukusebenza kokuyeka kokuqalisa okuphendulayo, okubalulekile ekugcineni okuphumayo ezinqubweni zokuhlola ezinembayo.
Ngomthamo womthwalo ongu-40 kg kanye nokulungiswa okungu-100 nm (0.0001 mm), inkundla ivala igebe phakathi kokukhohlisa okuncane nokuqiniswa kwezimboni—imisebenzi ehlukahlukene eyenza isithakazelo esikhulu kuyo yonke imikhakha yokukhiqiza.
Ukuguqula Izimboni Ezibalulekile
Imithelela yalokhu kugqama okunembayo kunabela emikhakheni eminingi yobuchwepheshe obuphezulu:
Ekwenziweni kwe-semiconductor, lapho ngisho nokukhubazeka kwesikali se-nanometer kungenza ama-chips angabi namsebenzi, ukuzinza kweplathifomu kushintsha ukuhlolwa kwe-wafer kanye nezinqubo zokuqondanisa i-photolithography. “Sibona amazinga okutholwa kokukhubazeka eba ngcono ngo-37% ezivivinyweni zakuqala,” kubika u-Michael Torres, unjiniyela omkhulu wezinqubo kumkhiqizi ohamba phambili we-semiconductor. "Ukuncibilika kokudlidliza kwesisekelo semabula kususe i-micro-wobble ebifihle izici ze-sub-50 nm ngaphambilini."
Ukukhiqizwa kwe-Precision Optical kungomunye ozuzayo. Ukupholishwa kwamalensi nezinqubo zokuhlanganisa ezake zadinga amahora okulungisa okwenziwa ngesandla okunzima manje zingazenzakalela ngokuma kwe-sub-micron yeplathifomu, kunciphise izikhathi zokukhiqiza kuyilapho kuthuthukisa ukungaguquguquki kokusebenza kokubona.
Ocwaningweni lwe-biomedical, inkundla inika amandla impumelelo ekukhohlisweni kweseli elilodwa kanye nesithombe se-microscopic sokulungiswa okuphezulu. UDkt. Sarah Johnson woMnyango Wezobunjiniyela Bezinto Eziphilayo e-Stanford uyaphawula, “Ukuzinza kusivumela ukuthi sigcine sigxile ezakhiweni zamaselula isikhathi eside, sithwebula izithombe ezidlula isikhathi eziveza izinqubo zebhayoloji ebezifihlwe ngaphambilini ukuguguleka kwemishini.”
Ezinye izinhlelo zokusebenza ezibalulekile zifaka imishini yokulinganisa yokunemba okuphezulu kokudidiyela (ama-CMM), ukupakishwa kwama-microelectronics, namathuluzi ocwaningo lwesayensi athuthukisiwe—zonke izindawo lapho inhlanganisela eyingqayizivele yesikhulumi yokunemba, ukuzinza, nomthamo wokulayisha ibhekana nemikhawulo yobuchwepheshe emile.
Ikusasa Lokukhiqiza Ngokunembe Kakhulu
Njengoba ukukhiqiza kuqhubeka nokucindezela kwakho okungapheli ku-miniaturization kanye namazinga aphezulu okusebenza, isidingo sezinhlelo zokumisa ezinembe kakhulu sizokhula kuphela. I-Precision Marble Three-Axis Gantry Platform ayimeleli nje intuthuko eqhubekayo kodwa ushintsho olubalulekile endleleni ukunemba okufinyelelwa ngayo—ukusebenzisa izakhiwo zemvelo ezihambisana nobunjiniyela obuthuthukisiwe kunokuthembela kuphela ezinhlelweni zesinxephezelo ezisebenzayo eziyinkimbinkimbi.
Kubakhiqizi abazulazula ezinseleleni ze-Industrial 4.0, le nkundla inikeza amazwibela ekusasa lobunjiniyela obunembayo. Ikusasa lapho umugqa ophakathi “kokunemba zelabhorethri” kanye “nokukhiqizwa kwezimboni” uqhubeka nokufiphala, okuvumela izinto ezintsha ezizoshintsha yonke into kusukela kuma-elekthronikhi esizukulwaneni esilandelayo kuya kumishini yezokwelapha esindisa ukuphila.
Njengoba omunye umhlaziyi wemboni akubeka: “Ezweni lokukhiqiza okunembayo, ukuzinza akusona nje isici—kuyisisekelo okwakhiwa kuso zonke ezinye intuthuko.
