Umatshini wokulinganisa ukulungelelanisa (CMM) luhlobo lwezixhobo zokulinganisa ngokuchanekileyo, eziye zatsala ingqalelo enkulu kwaye zisetyenziswe ngokubanzi kwiimpawu zayo zokuchaneka okuphezulu, ukusebenza kakuhle kunye nokuthembeka okuphezulu.Njengenye yamacandelo e-CMM, iimpawu zomzimba zegranite kunye nezinto eziphathekayo zikwayenye yezinto eziphambili ezichaphazela ukuthandwa kunye nokusetyenziswa komgangatho weCMM.
Nangona kunjalo, ingaba iintlobo ezahlukeneyo zegranite ziya kuvelisa umahluko kwiziphumo zokulinganisa umatshini wokulinganisa ulungelelaniso kuye kwaxoxwa ngokushushu.Kwisicelo esisebenzayo, abasebenzisi abaninzi baya kuba nomehluko omkhulu phakathi kweziphumo zokulinganisa kunye nexabiso lokwenyani, kwaye ezi mpazamo zihlala zihambelana nezinto zegranite ezisetyenzisiweyo.
Okokuqala, izixhobo ezahlukeneyo ze-granite zinobulukhuni obuhlukeneyo bomatshini kunye ne-elastic modulus, echaphazela ngokuthe ngqo ukuchasana kwe-deformation kunye nokuqina kwe-deformation.Okukhona ubulukhuni bomatshini begranite, kokukhona komelele ukuxhathisa kwayo deformation, kuba umatshini wokulinganisa ulungelelaniso ixesha elide, amandla aphezulu ukuguquguquka ukulungelelaniswa kwakhona phezulu.Okukhona imodyuli elastiki yegranite inkulu, kokukhona ukomelela kwe-deformation, kunokubuyela kwimeko yangaphambili ngokukhawuleza, ngaloo ndlela kuncitshiswe iimpazamo.Ke ngoko, ekukhetheni i-CMM, izixhobo zegranite ezinobunzima obuphezulu bomatshini kunye nemodyuli elastiki kufuneka zikhethwe.
Okwesibini, igranulation yegranite nayo inefuthe elikhulu kwiziphumo zomlinganiselo.Ezinye izinto zegranite zikhulu kakhulu okanye zincinci kakhulu, uburhabaxa bomphezulu bukhulu kakhulu, ezi zinto zinokubangela impazamo yomatshini wokulinganisa wolungelelwaniso.Ukuze ufumane iziphumo ezichanekileyo zokulinganisa, ingqwalasela ekhethekileyo kufuneka ihlawulwe kumgangatho ophezulu kunye neqondo lokucubungula xa ukhetha izinto zegranite.
Ukongezelela, i-coefficient yokwandiswa kwe-thermal yezinto ze-granite zihluke, kwaye iidigri ezahlukeneyo ze-thermal deformation ziya kuveliswa ixesha elide lokulinganisa.Ukuba isicatshulwa esine-coefficient encinci yokwandiswa kwe-thermal ikhethiwe, impazamo ebangelwa yi-coefficient eyahlukileyo yokwandiswa kwe-thermal ingancitshiswa.
Ngamafutshane, impembelelo yeentlobo ezahlukeneyo zezinto zegranite kumatshini wokulinganisa ulungelelaniso zihluke, kwaye izixhobo ezifanelekileyo zegranite kufuneka zikhethwe ukulinganisa ngokweemfuno.Ekusetyenzisweni okwenyani, kufuneka kuqwalaselwe ngokubanzi ngokweempawu ezibonakalayo zegranite kunye nomgangatho wokusetyenzwa kwemathiriyeli ukufumana iziphumo ezichanekileyo nezichanekileyo zokulinganisa.
