I-CMM (umatshini wokulinganisa olungelelanisiweyo) sisixhobo esibalulekileyo esisetyenziselwa ukulinganisa ukuchaneka kweendawo ezintsonkothileyo zejometri kumashishini ahlukeneyo afana neemoto, i-aerospace, kunye nezonyango. Ukuqinisekisa iziphumo zokulinganisa ezichanekileyo nezihambelanayo, umatshini we-CMM kufuneka uxhotyiswe ngezinto zegranite ezikumgangatho ophezulu ezibonelela ngenkxaso ezinzileyo neqinileyo kwiiprobe zokulinganisa.
I-Granite yinto efanelekileyo kwi-CMM ngenxa yokuchaneka kwayo okuphezulu, i-coefficient yokwandisa ubushushu obuphantsi, kunye nozinzo oluhle kakhulu. Nangona kunjalo, njengayo nayiphi na enye into, i-granite inokuguga ngokuhamba kwexesha ngenxa yokusetyenziswa rhoqo, izinto ezingqongileyo, kunye nezinye izinto. Ke ngoko, kubalulekile ukuvavanya inqanaba lokuguguleka kwe-granite kunye nokuzitshintsha xa kuyimfuneko ukuqinisekisa ukuchaneka nokuthembeka kokulinganisa kwe-CMM.
Enye yezinto eziphambili ezichaphazela ukuguguleka kwezixhobo zegranite kukuguguleka kokusetyenziswa kwazo. Okukhona kusetyenziswa icandelo legranite rhoqo, kokukhona kunokwenzeka ukuba liguguleke. Xa uvavanya izinga lokuguguleka kwezixhobo zegranite kwi-CMM, kubalulekile ukuqwalasela inani lemijikelo yokulinganisa, ukuguguleka kokusetyenziswa, amandla asetyenziswayo ngexesha lokulinganisa, kunye nobukhulu beeprobe zokulinganisa. Ukuba igranite isetyenziswa ixesha elide kwaye ibonisa iimpawu zomonakalo, ezinje ngokuqhekeka, iitships, okanye ukuguguleka okubonakalayo, lixesha lokutshintsha icandelo.
Enye into ebalulekileyo echaphazela ukuguguleka kwezixhobo zegranite ziimeko zokusingqongileyo. Oomatshini beCMM bahlala bekwiigumbi zemetrology ezilawulwa bubushushu ukuze kugcinwe imeko-bume ezinzileyo yokulinganisa ngokuchanekileyo. Nangona kunjalo, nakwiigumbi ezilawulwa bubushushu, ukufuma, uthuli, kunye nezinye izinto zokusingqongileyo zisenokuchaphazela ukuguguleka kwezixhobo zegranite. Igranite isengozini yokufunxwa ngamanzi kwaye inokuba nemingxunya okanye iitships xa ivezwe kumswakama ixesha elide. Ke ngoko, kubalulekile ukugcina imeko-bume kwigumbi lemetrology icocekile, yomile, kwaye ingenazo inkunkuma enokonakalisa izixhobo zegranite.
Ukuqinisekisa umlinganiselo ochanekileyo, kuyimfuneko ukujonga rhoqo imeko yezinto zegranite nokufumanisa ukuba ziyafuneka na ukutshintshwa. Umzekelo, ukuhlolwa komphezulu wegranite ukuze kubonwe ukuba unemifantu, iitships okanye iindawo ezigugileyo ezibonakalayo kubonisa ukuba into leyo ifuna ukutshintshwa. Kukho iindlela ezahlukeneyo zokuvavanya inqanaba lokuguguleka kwezinto zegranite kwi-CMM. Indlela eqhelekileyo nelula kukusebenzisa umphetho othe tye ukujonga ukuba zithe tyaba kwaye zigugile na. Xa usebenzisa umphetho othe tye, qwalasela inani lamanqaku apho umphetho udibana khona negranite, kwaye ujonge naziphi na izikhewu okanye iindawo ezirhabaxa kumphezulu. I-micrometer ingasetyenziselwa ukulinganisa ubukhulu bezinto zegranite nokufumanisa ukuba kukho na inxalenye egugileyo okanye ebole.
Ukuqukumbela, imeko yezinto zegranite kumatshini weCMM ibalulekile ekuqinisekiseni umlinganiselo ochanekileyo nochanekileyo. Kubalulekile ukuvavanya rhoqo inqanaba lokuguguleka kwezinto zegranite kwaye uzitshintshe xa kuyimfuneko. Ngokugcina imeko-bume kwigumbi le-metrology icocekile, yomile, kwaye ingenazo inkunkuma, kunye nokujonga iimpawu ezibonakalayo zokuguguleka, abaqhubi beCMM banokuqinisekisa ukuba izinto zabo zegranite zihlala ixesha elide kwaye bagcine ukuchaneka nokuthembeka kwezixhobo zabo zokulinganisa.
