Njengoba izinhlelo zokulinganisa ngokunemba ziqhubeka nokuthuthuka ziye esivinini esiphezulu, ukuphatheka kalula, kanye nokunemba kwe-sub-micron, ukukhethwa kwezinto kuye kwaba yinto ebalulekile yobunjiniyela kunokuba kube yinto yesibili yokucatshangelwa komklamo. Kulesi simo, ama-composites aqiniswe nge-carbon fiber (CFRP) asetshenziswa kakhulu emishinini yokulinganisa ehlanganisiwe (ama-CMM) kanye namadivayisi e-metrology aphathekayo, anikeza inhlanganisela eyingqayizivele yesakhiwo esilula kanye nokuzinza okuphezulu.
Ngokwesiko, imishini ye-metrology ithembele ku-aluminium noma insimbi ukuze kutholakale izakhi zesakhiwo ngenxa yezakhiwo zayo eziqondakala kahle zemishini kanye nokukwazi kwayo ukukhiqiza. Kodwa-ke, lezi zinto ziveza imikhawulo yemvelo lapho izinhlelo zidingeka ukuze kufezwe kokubili ukuhamba kanye nokunemba okuphezulu kakhulu. Ubuningi obukhulu bezinsimbi buyandisa ukungabi namandla kwesakhiwo, kunciphisa ukuphendula okuguquguqukayo, kuyilapho izici zazo zokukhula kokushisa ziletha ukuzulazula kokulinganisa ezindaweni ezingalawulwa. Lezi zingqinamba zibonakala kakhulu ezingalweni zokulinganisa eziphathwayo kanye nezakhiwo ezinkulu ze-CMM ezisetshenziswa ezindizeni zezindiza kanye nezicelo zokuhlola endaweni.
Izinhlanganisela ze-carbon fiber zibhekana nalezi zinselele ezingeni lezinto ezibonakalayo. Njengoba ubuningi buphansi kakhulu kunensimbi ngisho ne-aluminium, kuhlanganiswe ne-modulus ephezulu yokuguquguquka, i-CFRP ivumela ukwakheka kwezingxenye zokunemba ezilula ngaphandle kokulahlekelwa ukuqina. Lesi silinganiso sokuqina okuphezulu kuya kwesisindo sibalulekile ezinhlelweni ze-metrology lapho ukuguquguquka kwesakhiwo kuthinta ngqo ukunemba kokulinganisa. Ngokunciphisa isisindo ngenkathi kugcinwa ukuqina, izingxenye ze-carbon fiber zithuthukisa ukuziphatha okuguquguqukayo, okuvumela ukubeka ngokushesha kanye nesikhathi sokuphumula esincishisiwe ngesikhathi sokujikeleza kokulinganisa.
Okubaluleke ngokulinganayo ukusebenza kokushisa kwezinto ze-carbon fiber. Ngokungafani nezinsimbi, ezibonisa ama-coefficient aphezulu futhi afanayo okwanda kokushisa, izinhlanganisela ze-carbon fiber zingaklanywa ukuze kufezwe ukwanda kokushisa okucishe kube yi-zero noma okulawulwa kakhulu ngezindlela ezithile. Lesi sici sibalulekile ekugcineni ukuzinza kwejometri ngaphansi kwamazinga okushisa ashintshashintshayo, ikakhulukazi ezindaweni eziphathwayo noma ezisezingeni lesitolo lapho ukulawulwa kokushisa kunqunyelwe khona. Ngenxa yalokho, izingxenye ze-carbon fiber metrology zinegalelo ekunciphiseni okukhulu kokushisa, kunciphisa isidingo sama-algorithms ayinkimbinkimbi okubuyisela kanye nokuthuthukisa ukuthembeka kokulinganisa okuphelele.
Enye inzuzo ebalulekile isekuziphatheni kokudlidliza. Isakhiwo esihlanganisiwe se-carbon fiber sinikeza izici zokudambisa ezingokwemvelo ezingcono kunezinto eziningi zensimbi zendabuko. Ngokwezinto ezingokoqobo, lokhu kunciphisa ukudluliselwa kanye nokwandiswa kokudlidliza kwangaphandle nangaphakathi, okungase kunciphise ikhwalithi yesiginali yokulinganisa. Ngezingalo zokulinganisa ezinembe kakhulu kanye nezinhlelo zokuskena, ukudlidliza okuthuthukisiwe kuhumusha ngqo ekuphindaphindweni okungcono kanye nokuthembeka kokulinganisa ubuso.
Kusukela embonweni wokuklama nokukhiqiza, i-carbon fiber iphinde ivumele izinga eliphezulu lokuhlanganiswa kwesakhiwo. Ngamaqhinga okubeka aklanyelwe kanye nezinqubo zokwenziwa ezisekelwe kusikhunta, onjiniyela bangenza ngcono ukuqondiswa kwe-fiber ukuze kufane nezindlela ezithile zomthwalo, bafinyelele izici zokusebenza ze-anisotropic ezingenakwenzeka ngezinsimbi ze-isotropic. Lokhu kuvumela ukuhlanganiswa kwezici ezisebenzayo ezifana nokufakwa okufakiwe, izixhumi zenzwa, kanye nomzila wekhebula ngaphakathi kwesakhiwo esisodwa, kunciphisa ubunzima bokuhlangana kanye namaphutha okuqondanisa aqongelelekayo.
Kubakhiqizi bezingalo zokulinganisa ezinembe kakhulu kanye nezinhlelo ze-CMM ezithuthukisiwe, lezi zinzuzo zezinto ezibonakalayo zisekela ndawonye inhloso ebalulekile yokugcina ukunemba okungu-0.001 mm ngenkathi kunciphisa isisindo sesistimu iyonke. Lokhu kubaluleke kakhulu kwizixazululo ze-metrology zesizukulwane esilandelayo ezibeka phambili ukuphatheka, ukulula kokusebenza, kanye nokuguquguquka kokusetshenziswa ngaphandle kokubeka engcupheni ukusebenza kokulinganisa.
Ngakho-ke ukwamukelwa kwe-carbon fiber ku-metrology akuyona nje indlela yokuklama okulula, kodwa kuyindlela yokuphendula ehlakaniphile ezidingweni zohlelo lokusebenza ezishintshayo. Ezimbonini ezifana nezindiza, i-semiconductor, kanye nokukhiqizwa kokunemba, lapho ukunemba kokulinganisa kuthinta ngqo ikhwalithi yomkhiqizo kanye nekhono lenqubo, ikhono lokuhlanganisa ukuhamba nokunemba okuphezulu kakhulu limelela inzuzo enkulu yokuncintisana.
Kwa-ZHHIMG, ukuthuthukiswa kwezingxenye ze-carbon fiber metrology kubhekwa njengenselele yobunjiniyela ezingeni lesistimu, okuhlanganisa isayensi yezinto ezibonakalayo, ukwakheka kwesakhiwo, kanye nezinqubo zokukhiqiza ngokunemba. Ngokusebenzisa ubuchwepheshe obuhlanganisiwe obuthuthukisiwe, i-ZHHIMG isekela abakhiqizi bemishini ye-metrology ekufinyeleleni amazinga amasha okusebenza, okwenza kube lula izinhlelo zokulinganisa ezilula, ezisheshayo, nezinembile kakhulu zezicelo zezimboni ezidingayo.
