Umatshini wokulinganisa olungelelanisiweyo (i-CMM) luhlobo lwezixhobo zokulinganisa ngokuchanekileyo okuphezulu, eziye zatsala ingqalelo enkulu kwaye zasetyenziswa kakhulu ngenxa yeempawu zazo zokuchaneka okuphezulu, ukusebenza kakuhle kunye nokuthembeka okuphezulu. Njengenye yezinto zeCMM, iimpawu zomzimba zegranite kunye nezinto nazo zezinye zezinto eziphambili ezichaphazela ukuthandwa kunye nomgangatho wokusetyenziswa kweCMM.
Nangona kunjalo, ukuba iintlobo ezahlukeneyo zegranite ziya kuvelisa umahluko kwiziphumo zokulinganisa zomatshini wokulinganisa i-coordinate kuye kwaxoxwa kakhulu. Kwindlela esebenzayo, abasebenzisi abaninzi baya kuba nomahluko omkhulu phakathi kweziphumo zokulinganisa kunye nexabiso lokwenyani, kwaye ezi mpazamo zihlala zinxulumene nezinto zegranite ezisetyenzisiweyo.
Okokuqala, izinto ezahlukeneyo zegranite zinobunzima obahlukeneyo boomatshini kunye ne-elastic modulus, nto leyo echaphazela ngokuthe ngqo ukumelana kwayo nokuguquguquka kunye nokuqina kokuguquguquka. Okukhona ubunzima boomatshini begranite bukhulu, kokukhona ukumelana kwayo nokuguquguquka kunamandla, kumatshini wokulinganisa olungelelanisiweyo ixesha elide, ukuguquguquka kokulinganisa amandla aphezulu nako kuphezulu. Okukhona i-elastic modulus yegranite inkulu, kokukhona ukuqina kokuguquguquka kunamandla, kunokubuyela kwimeko yokuqala ngokukhawuleza, ngaloo ndlela kunciphisa iimpazamo. Ke ngoko, ekukhetheni i-CMM, kufuneka kukhethwe izixhobo zegranite ezinobunzima obuphezulu boomatshini kunye ne-elastic modulus.
Okwesibini, i-granulation ye-granite nayo inempembelelo enkulu kwiziphumo zokulinganisa. Amanye amasuntswana ezinto ze-granite makhulu kakhulu okanye mancinci kakhulu, uburhabaxa bomphezulu bukhulu kakhulu, ezi zinto zinokubangela impazamo yomatshini wokulinganisa odibeneyo. Ukuze kufunyanwe iziphumo zokulinganisa ezichanekileyo, kufuneka kuqwalaselwe ngokukodwa kumgangatho womphezulu kunye nomgangatho wokucubungula xa kukhethwa izinto ze-granite.
Ukongeza, i-coefficient yokwandiswa kobushushu bezinto zegranite yahlukile, kwaye amanqanaba ahlukeneyo okuguqulwa kobushushu aya kuveliswa ukuze kulinganiswe ixesha elide. Ukuba izinto ezine-coefficient encinci yokwandiswa kobushushu zikhethiwe, impazamo ebangelwe yi-coefficient eyahlukileyo yokwandiswa kobushushu ingancitshiswa.
Ngamafutshane, impembelelo yeentlobo ezahlukeneyo zezinto zegranite kumatshini wokulinganisa i-coordinate yahlukile, kwaye izinto zegranite ezifanelekileyo kufuneka zikhethwe ukuze zilinganiswe ngokweemfuno. Ekusetyenzisweni kwayo, kufuneka ziqwalaselwe ngokupheleleyo ngokweempawu zomzimba zegranite kunye nomgangatho wokucubungula izinto ukuze kufunyanwe iziphumo zokulinganisa ezichanekileyo nezichanekileyo.
