Umshini wokulinganisa oqondile (i-CMM) uhlobo lwemishini yokulinganisa enembile kakhulu, edonsele ukunaka okukhulu futhi isetshenziswe kabanzi ngenxa yezici zayo zokunemba okuphezulu, ukusebenza kahle okuphezulu kanye nokuthembeka okuphezulu. Njengenye yezingxenye ze-CMM, izici zomzimba ze-granite nezinto ezibonakalayo nazo zingenye yezinto ezibalulekile ezithinta ukuthandwa kanye nekhwalithi yokusetshenziswa kwe-CMM.
Kodwa-ke, ukuthi izinhlobo ezahlukene ze-granite zizoveza umehluko emiphumeleni yokulinganisa yomshini wokulinganisa kuye kwaphikiswana kakhulu ngawo. Ekusetshenzisweni okungokoqobo, abasebenzisi abaningi bazoba nomehluko omkhulu phakathi kwemiphumela yokulinganisa kanye nenani langempela, futhi la maphutha avame ukuhlotshaniswa nezinto ze-granite ezisetshenzisiwe.
Okokuqala, izinto ze-granite ezahlukene zinobulukhuni obuhlukile bomshini kanye ne-elastic modulus, okuthinta ngqo ukumelana kwayo nokuguquguquka kanye nokuqina kokuguquguquka. Uma ubulukhuni be-granite bukhula, ukumelana kwayo nokuguquguquka kunamandla, kumshini wokulinganisa ohlanganisa isikhathi eside, ukuzivumelanisa nezimo kokulinganisa amandla aphezulu nakho kuphakeme. Uma i-elastic modulus ye-granite inkulu, ukuqina kokuguquguquka kunamandla, kungabuyela esimweni sokuqala ngokushesha, ngaleyo ndlela kuncishiswe amaphutha. Ngakho-ke, ekukhetheni i-CMM, izinto ze-granite ezinobulukhuni obuphezulu bomshini kanye ne-elastic modulus kufanele zikhethwe.
Okwesibili, i-granulation ye-granite nayo inethonya elikhulu emiphumeleni yokulinganisa. Ezinye izinhlayiya zezinto ze-granite zikhulu kakhulu noma zincane kakhulu, ubulukhuni bomphezulu bukhulu kakhulu, lezi zici zingabangela iphutha lomshini wokulinganisa ohambisanayo. Ukuze kutholakale imiphumela yokulinganisa enembile, kudingeka kuqashelwe ngokukhethekile ikhwalithi yomphezulu kanye nezinga lokucubungula lapho kukhethwa izinto ze-granite.
Ngaphezu kwalokho, i-coefficient yokwandisa ukushisa kwezinto ze-granite ihlukile, futhi amazinga ahlukene okuguquguquka kokushisa azokhiqizwa ukuze kulinganiswe isikhathi eside. Uma izinto ezine-coefficient encane yokwandisa ukushisa zikhethwa, iphutha elibangelwa i-coefficient ehlukile yokwandisa ukushisa lingancishiswa.
Ngamafuphi, umthelela wezinhlobo ezahlukene zezinto ze-granite emshinini wokulinganisa uhlukile, futhi izinto ze-granite ezifanele kufanele zikhethwe ukuze zilinganiswe ngokwezidingo. Ekusetshenzisweni kwangempela, kufanele kucatshangelwe ngokuphelele ngokwezici zomzimba ze-granite kanye nekhwalithi yokucubungula izinto ukuze kutholakale imiphumela yokulinganisa enembile nenembile.
