Amapulatifomu okunemba kwe-granite ayizingxenye ezibalulekile ezimbonini ezidinga ukunemba okuphezulu nokuzinza, njenge-metrology, ukukhiqizwa kwe-semiconductor, kanye nobunjiniyela bemishini. Esinye sezakhiwo ezibalulekile zezinto ezichaza ukusebenza kwala mapulatifomu “i-elastic modulus,” evame ukubizwa ngokuthi i-modulus of elasticity. Le parameter ithonya ngqo ukumelana kwepulatifomu ekuguqukeni ngaphansi kwamandla asetshenziswayo, okuqinisekisa ukusebenza kwayo ekulinganisweni okunembile kanye nokusebenza okunembile okuphezulu.
I-modulus elastic yezinto ezibonakalayo iyisilinganiso sokuqina kwazo, ilinganisa ukuthi ziwohloka kangakanani ngaphansi komthwalo othile. Ngokuqondile, ichaza ubudlelwano phakathi kokucindezeleka (amandla endaweni ngayinye) kanye nokucindezeleka (ukuguquguquka) ngaphakathi kwezinto ezibonakalayo lapho ziguqulwa zibe yi-elastic. I-modulus elastic ephezulu isho ukuthi izinto ezibonakalayo ziqinile, futhi ukuma kwazo akushintshani kangako ngaphansi kokucindezeleka. Endabeni ye-granite, into eqinile ngokwemvelo futhi eqinile, i-modulus yayo elastic ephezulu yenza imelane nokuguquguquka, ngisho nangaphansi kwemithwalo emikhulu.
Kumapulatifomu okunemba kwe-granite, le mfanelo ibalulekile. Lawa mapulatifomu avame ukusetshenziswa ezinhlelweni zokusebenza ezidinga ukubekezelelana okuqinile kakhulu kanye nokusebenza okuhlala njalo ngokuhamba kwesikhathi. Uma i-modulus inwebeka kakhulu, kulapho ipulatifomu izogoba noma iphenduke kancane ngaphansi kwesisindo, okuqinisekisa ukuthi izilinganiso zihlala zinembile ngisho nalapho ipulatifomu isetshenziswa isikhathi eside noma ngaphansi kwezimo zemvelo ezahlukahlukene.
Ukuqina kwe-granite okungokwemvelo kuyisiza ukuthi igcine ubuqotho bayo bejometri, okubalulekile ezinhlelweni zokusebenza ezifana nemishini yokulinganisa edidiyelwe (ama-CMM) kanye namanye amadivayisi okulinganisa ngokunemba. Ukuqina kwezinto kubalulekile ekuqinisekiseni ukuthi imiphumela ayiphazamiseki ngenxa yokuguquguquka okungadingeki, okungaletha amaphutha okulinganisa noma ukungalungi kahle.
Ngaphezu kwalokho, i-modulus enwebekayo ye-granite inegalelo ekhonweni layo lokumunca nokunciphisa ukudlidliza. Lokhu kubaluleke kakhulu ezindaweni lapho ukudlidliza kwangaphandle kungathinta khona ukunemba kokulinganisa. Ukuhlanganiswa kokuguquguquka okuphansi ngaphansi komthwalo kanye nokumelana nokudlidliza okuphezulu kwenza i-granite ibe yinto efanelekile yamapulatifomu okunemba asetshenziswa ezindaweni zezimboni ezinembe kakhulu.
Ekuphetheni, i-modulus elastic yamapulatifomu okunemba kwe-granite iyisici esibalulekile esichaza ikhono lawo lokumelana nokuguquguquka ngaphansi komthwalo. Iqinisekisa ukuzinza, ukunemba, kanye nokuthembeka ekusetshenzisweni kokulinganisa okubucayi, okwenza i-granite ibe yinto ekhethwayo yezimboni ezidinga ukusebenza okunembile nokungaguquguquki. Kungakhathaliseki ukuthi kuyi-metrology, ubunjiniyela, noma ukukhiqiza, i-modulus elastic ephezulu ye-granite idlala indima ebalulekile ekugcineni ubuqotho bemishini yokunemba, okunegalelo ekusetshenzisweni kwayo kabanzi ekusetshenzisweni kokusebenza okuphezulu.
Lokhu kuhlanganiswa kwamandla nokuqina yikho okwenza amapulatifomu okunemba kwe-granite abe yigugu kakhulu ezindaweni zezimboni ezidinga kakhulu.
