Umshini wokulinganisa oqondile (i-CMM) uhlobo lwethuluzi lokulinganisa elinokunemba okuphezulu elisetshenziswa kabanzi embonini yokukhiqiza. Bangalinganisa indawo enobukhulu obuthathu kanye nesimo sezinto futhi banikeze izilinganiso ezinembile kakhulu. Kodwa-ke, ukunemba kokulinganisa kwe-CMM kuthinteka yizici eziningi, esinye sezici ezibaluleke kakhulu ukunemba kwejometri kanye nekhwalithi yobuso bezingxenye ze-granite ezisebenzisayo.
I-Granite iyinto evame ukusetshenziswa ekwakhiweni kwemishini yokulinganisa ehambisanayo. Izakhiwo zayo ezisezingeni eliphezulu, njengesisindo esikhulu, ubulukhuni obuphezulu, kanye nokuqina okuqinile, kwenza kube ukukhetha okuhle kokuqina kobukhulu kanye nokunemba kokulinganisa. Ine-coefficient encane yokwanda kokushisa, ngaleyo ndlela inciphisa ukukhukhuleka kokushisa kwemiphumela elinganisiwe. Ngakho-ke, zivame ukusetshenziswa njengeplatifomu yokubhekisela, ibhentshi lokusebenzela kanye nezinye izingxenye eziyinhloko ze-CMM ukuqinisekisa imiphumela yokulinganisa enembile kakhulu.
Ukunemba kwejiyomethri kungenye yezinto eziyisisekelo ekucutshungulweni kwezingxenye zegranite. Kuhlanganisa ukunemba okuhleliwe kwezingxenye zegranite, ukuzungeza, ukulingana, ukunemba njalo njalo. Uma la maphutha ejiyomethri ethinta kakhulu ukuma nokuma kwezingxenye zegranite, amaphutha okulinganisa azokwanda kakhulu. Isibonelo, uma ipulatifomu yokubhekisela esetshenziswa umshini wokulinganisa i-coordinate ingasheleli ngokwanele, futhi kukhona izinga elithile lokuguquguquka nokukhukhumala ebusweni bayo, iphutha lokulinganisa lizokhuliswa kakhulu, futhi kudingeka isinxephezelo sezinombolo.
Ikhwalithi yobuso inomthelela osobala ekusebenzeni kokulinganisa kwe-CMM. Lapho kucutshungulwa izingxenye ze-granite, uma ukwelashwa kobuso kungekho, kunezinkinga zobuso ezifana nemigodi nama-pores, kuzoholela ekubeni lukhuni okuphezulu kobuso kanye nekhwalithi yobuso ephansi. Lezi zici zizothinta ukunemba kokulinganisa, zinciphise ukunemba kokulinganisa, bese zithinta ikhwalithi yomkhiqizo, inqubekela phambili kanye nokusebenza kahle.
Ngakho-ke, enkambisweni yokukhiqiza izingxenye ze-CMM, kubalulekile ukunaka ukunemba kwejometri kanye nekhwalithi yobuso bezingxenye ze-granite ukuqinisekisa ukusebenza kwayo kokulinganisa. Ukusika, ukugaya, ukupholisha kanye nokusika ucingo kwenqubo yokugcina kumele kwenziwe ngokuhambisana nendinganiso, futhi ukunemba kungahlangabezana nezidingo zokwenziwa kwe-CMM. Uma ukunemba kwezingxenye ze-granite ezisetshenziswa ku-CMM kuphakeme, ukunemba kokulinganisa kuphakeme uma kugcinwa kahle ekusetshenzisweni kwansuku zonke.
Ngamafuphi, ukunemba kanye nekhwalithi yobuso bezingxenye ze-granite kubalulekile ekusebenzeni kokulinganisa kwe-CMM, futhi ukunaka le mininingwane lapho kukhiqizwa i-CMM kuyisihluthulelo sokuqinisekisa ukunemba nokuqina kokulinganisa. Njengoba izingxenye ezahlukene zesakhiwo se-CMM zenziwe nge-granite, imabula kanye namanye amatshe, lapho ikhwalithi izinzile, ukusetshenziswa kwesikhathi eside noma ukulinganiswa ezinhlobonhlobo eziningi zezinguquko zokushisa kungaqinisekisa ukuthi ukunemba kuzinzile, ukuze kuqinisekiswe ukunemba nokuthembeka kokukhiqiza kanye nokukhiqiza.
