Isisekelo se-granite siyingxenye ebalulekile yokulinganisa okunembile nokunembile ku-Coordinate Measurement Machines (CMMs). Isisekelo se-granite sinikeza indawo ezinzile neqondile yokuhamba kwe-probe yokulinganisa, okuqinisekisa imiphumela enembile yokuhlaziywa kobukhulu. Ngakho-ke, ngesikhathi sokufakwa kwesisekelo se-granite ku-CMM, kunezici eziningana ezibalulekile okudingeka uzinake, ukuqinisekisa ukufakwa okuphumelelayo.
Okokuqala, kubalulekile ukuqinisekisa ukuthi indawo yokufaka ihlanzekile, yomile, futhi ayinazo izinsalela, uthuli, noma umswakama. Noma yikuphi ukungcola okungaba khona endaweni yokufaka kungaphazamisa ukuhleleka kwesisekelo se-granite, okubangela ukungalungi ezilinganisweni. Ngakho-ke, qiniseka ukuthi uhlanza indawo yokufaka kahle ngaphambi kokuqala inqubo yokufaka.
Okwesibili, kubalulekile ukuhlola ukuthi indawo yokufaka ithambile futhi ilinganiswe kahle. Isisekelo segranite sidinga indawo eyisicaba ukuqinisekisa ukuthi ihlezi kahle endaweni yokufaka. Ngakho-ke, sebenzisa izinga elinembile kakhulu ukuqinisekisa ukuthi indawo yokufaka ilinganiswe kahle. Ngaphezu kwalokho, kufanele uhlole ukuthi indawo yokufaka ithambile kangakanani usebenzisa umphetho oqondile noma ipuleti lobuso. Uma indawo yokufaka ingekho kahle, kungadingeka usebenzise ama-shim ukuze ulinganisele kahle isisekelo segranite.
Okwesithathu, qiniseka ukuthi isisekelo se-granite siqondile futhi silinganisiwe kahle. Isisekelo se-granite sidinga ukulungelelaniswa kahle kanye nokulinganisa ukuze kuqinisekiswe ukuthi siqondiswe kahle nokuthi i-probe yokulinganisa ihamba ngokunembile phezu kobuso. Ngakho-ke, sebenzisa izinga elinembile kakhulu ukuze ulinganise isisekelo se-granite. Ngaphezu kwalokho, sebenzisa inkomba yokudayela ukuqinisekisa ukuthi isisekelo se-granite siqondile kahle. Uma isisekelo se-granite singalinganisiwe noma singalinganisiwe kahle, i-probe ngeke ihambe emgqeni oqondile, okuholela ekulinganisweni okunganembile.
Ngaphezu kwalokho, ngesikhathi sokufakwa kwesisekelo se-granite, kubalulekile ukusebenzisa uhlobo olufanele lwehadiwe yokufaka ukuze uyiqinise endaweni yayo. Ihadiwe yokufaka kufanele yakhelwe ukumelana nesisindo sesisekelo se-granite futhi iqinisekise ukuthi iboshwe kahle endaweni yokufaka. Ngaphezu kwalokho, qiniseka ukuthi ihadiwe yokufaka ayiphazamisi ukulingeneka noma ukuhambisana kwesisekelo se-granite.
Ekuphetheni, ukufakwa kwesisekelo se-granite ku-CMM kuyinqubo ebalulekile edinga ukunakwa ngokucophelela kwemininingwane. Ukuqinisekisa ukulinganiswa okunembile nokunembile, kubalulekile ukunaka ukuhlanzeka, ukuba yisicaba, ukulingana, ukuhambisana, kanye nokufakwa okufanele kwesisekelo se-granite. Lezi zici ezibalulekile zizoqinisekisa ukuthi i-CMM isebenza ngokunembile nangokungaguquguquki, inikeze imiphumela ethembekile yokuhlaziywa kobukhulu kanye nokulinganisa.
