I-CMM (umshini wokulinganisa ohlanganisayo) iyithuluzi elibalulekile elisetshenziselwa ukulinganisa ukunemba kwezingxenye zejiyometri eziyinkimbinkimbi ezimbonini ezahlukahlukene njengezimoto, izindiza, kanye nezokwelapha. Ukuqinisekisa imiphumela yokulinganisa enembile nehambisanayo, umshini we-CMM kumele uhlonyiswe ngezingxenye zegranite ezisezingeni eliphezulu ezinikeza ukwesekwa okuzinzile nokuqinile kuma-probe okulinganisa.
I-Granite iyinto efanelekile yezingxenye ze-CMM ngenxa yokunemba kwayo okuphezulu, i-coefficient yokukhulisa ukushisa okuphansi, kanye nokuqina okuhle kakhulu. Kodwa-ke, njenganoma iyiphi enye into, i-granite ingaguga futhi ngokuhamba kwesikhathi ngenxa yokusetshenziswa njalo, izici zemvelo, nezinye izici. Ngakho-ke, kubalulekile ukuhlola izinga lokuguga kwezingxenye ze-granite bese uzishintsha lapho kudingeka ukuqinisekisa ukunemba nokuthembeka kwezilinganiso ze-CMM.
Esinye sezici eziyinhloko ezithinta ukuguguleka kwezingxenye zegranite ukuvama kokusetshenziswa. Uma kusetshenziswa ingxenye yegranite kaningi, kulapho kungenzeka khona ukuthi iguge. Lapho kuhlolwa izinga lokuguguleka kwezingxenye zegranite ku-CMM, kubalulekile ukucabangela inani lemijikelezo yokulinganisa, ukuvama kokusetshenziswa, amandla asetshenziswa ngesikhathi sokulinganisa, kanye nosayizi wama-probe okulinganisa. Uma igranite isetshenziswa isikhathi eside futhi ikhombisa izimpawu zomonakalo, njengokuqhekeka, ama-chips, noma ukuguguleka okubonakalayo, sekuyisikhathi sokushintsha ingxenye.
Esinye isici esibalulekile esithinta ukuguguleka kwezingxenye zegranite yizimo zemvelo. Imishini ye-CMM ivame ukutholakala emakamelweni okumethriji alawulwa amazinga okushisa ukuze kugcinwe indawo ezinzile yokulinganisa ngokunembile. Kodwa-ke, ngisho nasemakamelweni alawulwa amazinga okushisa, umswakama, uthuli, nezinye izici zemvelo zingase zithinte ukuguguleka kwezingxenye zegranite. Igranite isengozini yokumuncwa amanzi futhi ingaba nemifantu noma ama-chips uma ivezwa umswakama isikhathi eside. Ngakho-ke, kubalulekile ukugcina indawo egumbini lokumethriji ihlanzekile, yomile, futhi ingenazo izinsalela ezingalimaza izingxenye zegranite.
Ukuqinisekisa ukulinganisa okunembile, kubalulekile ukuhlola njalo isimo sezingxenye zegranite bese unquma ukuthi zidinga ukushintshwa yini. Isibonelo, ukuhlolwa kobuso begranite ukuze ubone ukuthi bunemifantu, ama-chips noma izindawo ezigugile ezibonakalayo kusikisela ukuthi ingxenye idinga ukushintshwa. Kunezindlela ezahlukahlukene zokuhlola izinga lokuguguleka kwezingxenye zegranite ku-CMM. Indlela evamile neqondile ukusebenzisa unqenqema oluqondile ukuhlola ukuthi luyisicaba futhi lugugile yini. Uma usebenzisa unqenqema oluqondile, naka inani lamaphuzu lapho unqenqema luthinta khona igranite, bese uhlola noma yiziphi izikhala noma izindawo ezimagebhugebhu ebusweni. I-micrometer ingasetshenziswa futhi ukukala ubukhulu bezingxenye zegranite bese unquma ukuthi noma iyiphi ingxenye igugile noma igugile.
Ekuphetheni, isimo sezingxenye ze-granite emshinini we-CMM sibalulekile ekuqinisekiseni ukulinganiswa okunembile nokunembile. Kubalulekile ukuhlola izinga lokuguguleka kwezingxenye ze-granite njalo bese uzishintsha uma kudingeka. Ngokugcina indawo egumbini le-metrology ihlanzekile, yomile, futhi ingenazo imfucumfucu, nokubheka izimpawu ezibonakalayo zokuguguleka, abaqhubi be-CMM bangaqinisekisa ukuthi izingxenye zabo ze-granite zihlala isikhathi eside futhi balondoloze ukunemba nokuthembeka kwemishini yabo yokulinganisa.
