Uma kukhulunywa ngemishini yokulinganisa enezinhlanganisela ezintathu (i-CMM), ukunemba nokunemba kokulinganisa kubalulekile. Le mishini isetshenziswa ezimbonini ezahlukene njengezindiza, izimoto, ezokuvikela, ezokwelapha, nokuningi ukuqinisekisa ukuthi imikhiqizo eyenziwe ihlangabezana nemigomo eqondile futhi ihambisana nezindinganiso ezidingekayo. Ukunemba kwale mishini kuncike kakhulu ekhwalithini yomklamo womshini, uhlelo lokulawula, kanye nendawo esebenza kuyo. Esinye sezingxenye ezibaluleke kangaka ezidlala indima ebalulekile ekuqinisekiseni ukunemba kokulinganisa kwe-CMM isisekelo se-granite.
I-Granite iyitshe lemvelo eliqinile neliqinile elinokuqina okuhle kakhulu futhi alithinteki ukushintsha kwezinga lokushisa. Linokuqina okuphezulu, ukwanda okuphansi kokushisa, kanye nokumelana nokudlidliza, okwenza libe yinto efanelekile yezisekelo ze-CMM. Le nto futhi imelana kakhulu nokuguguleka, ukugqwala, kanye nokuguquka futhi kulula ukuyinakekela, okwenza kube inketho ehlala isikhathi eside yama-CMM.
Emishinini yokulinganisa enama-coordinate amathathu, isisekelo se-granite sinikeza indawo ezinzile nefanayo yokufaka isakhiwo nezingxenye zomshini. Ukuqina kwe-granite kuqinisekisa ukuthi i-CMM ayithinteki yizici zemvelo njengokushintshashintsha kwezinga lokushisa, ukudlidliza, noma ukunyakaza komhlabathi, okuqinisekisa ukulinganiswa okunembile nokuphindaphindwayo.
Isisekelo se-granite siyingxenye ebalulekile ekugcineni ukulingana okufanele kwama-axes omshini. Noma yikuphi ukungalungi kahle kwezingxenye zomshini kungathinta kakhulu ukunemba kwezilinganiso, njengoba amaphutha angahlanganiswa kulo lonke uhla lokulinganisa. Ngesisekelo se-granite esiqinile nesiqinile, izingxenye zesakhiwo somshini ziqiniswe ngokuqinile, futhi ama-axes omshini ahlala eqondile, ngaleyo ndlela kunciphisa amaphutha futhi kuqinisekiswe ukunemba okukhulu ekulinganisweni.
Esinye isici esenza i-granite ibe yinto efanelekile yezisekelo ze-CMM yikhono layo lokumelana nokwanda kokushisa. Izinga lokushisa lendawo lingathinta kakhulu ukunemba kwezilinganiso, njengoba noma yiziphi izinguquko ekushiseni zingabangela ukuthi izinto ezisetshenziswa emshinini zande noma zinciphe. Kodwa-ke, i-granite ine-coefficient ephansi yokwanda kokushisa, okusho ukuthi iyancipha futhi inwebe kancane kakhulu ngaphansi kokushintsha kwezinga lokushisa, okuqinisekisa ukulinganiswa okunembile.
Ekuphetheni, isisekelo se-granite ku-CMM siyingxenye ebalulekile ephethe ukuqinisekisa ukunemba kokulinganisa komshini. Ukuqina kwayo kobukhulu, ukuqina, kanye nokumelana nezimo zemvelo ezifana nokushintsha kwezinga lokushisa, ukudlidliza, kanye nokuguguleka kwenza kube yinto efanelekile yesisekelo se-CMM. Ngakho-ke, i-CMM enesisekelo se-granite iqinisekisa ukuthi ukulinganisa kunembile futhi kuyaphindaphindeka, okwenza kube ithuluzi eliwusizo kuzo zonke izimboni lapho ukunemba kubalulekile khona.
