Umshini wokulinganisa we-Coordinate (CMM) uwuhlobo lwethuluzi lokulinganisa elinembayo elisetshenziswa kabanzi embonini yokukhiqiza.Bangakwazi ukukala indawo enezinhlangothi ezintathu kanye nokuma kwezinto futhi banikeze izilinganiso ezinembe kakhulu.Kodwa-ke, ukunemba kokulinganisa kwe-CMM kuthintwa izici eziningi, enye yezinto ezibaluleke kakhulu ukunemba kwejometri kanye nekhwalithi ephezulu yezingxenye zegwadle ezisebenzisayo.
I-Granite iyinto evame ukusetshenziswa ekwenziweni kwemishini yokulinganisa edidiyelwe.Izici zayo ezibonakalayo eziphakeme, njengesisindo esikhulu, ubulukhuni obuphezulu, nokuzinza okuqinile, ziyenza ibe ukukhetha okuhle kokuzinza kobukhulu nokunemba kwesilinganiso.Ine-coefficient encane yokwandisa okushisayo, ngaleyo ndlela yehlise ukukhukhuleka kwezinga lokushisa kwemiphumela elinganisiwe.Ngakho-ke, zivame ukusetshenziswa njengenkundla yereferensi, ibhentshi lokusebenza nezinye izingxenye eziyinhloko ze-CMM ukuze kuqinisekiswe imiphumela yokulinganisa ngokunemba okuphezulu.
Ukunemba kwejiyomethri kungenye yezinto eziyisisekelo kakhulu ekucutshungulweni kwezingxenye ze-granite.Kuhlanganisa ukunemba kweplanethi yezingxenye zegwadle, ukuzungeza, ukufana, ukuqondisa nokunye.Uma lawa maphutha ejiyomethri ethinta kakhulu ukuma nokuma kwezingxenye ze-granite, amaphutha okulinganisa azokwanda nakakhulu.Isibonelo, uma inkundla yereferensi esetshenziswa umshini wokulinganisa wokudidiyela ibushelelezi ngokwanele, futhi kunezinga elithile lokuguquguquka kanye neqhubu ebusweni bayo, iphutha lokulinganisa lizothuthukiswa ngokwengeziwe, futhi isinxephezelo samanani siyadingeka.
Ikhwalithi yobuso inomthelela osobala kakhulu ekusebenzeni kokulinganisa kwe-CMM.Lapho ucubungula izingxenye ze-granite, uma ukwelashwa okungaphezulu kungekho endaweni, kukhona ukukhubazeka okungaphezulu njengemigodi nama-pores, kuzoholela ekuqineni okuphezulu kwendawo kanye nezinga eliphezulu eliphansi.Lezi zici zizothinta ukunemba kwesilinganiso, zinciphise ukunemba kwesilinganiso, bese zithinta ikhwalithi yomkhiqizo, ukuqhubeka nokusebenza kahle.
Ngakho-ke, ohlelweni lokukhiqiza izingxenye ze-CMM, kubalulekile ukunaka ukunemba kwejometri kanye nekhwalithi ephezulu yezingxenye ze-granite ukuqinisekisa ukusebenza kwayo kokulinganisa.Ukusika, ukugaya, ukupholisha kanye nokusika ucingo kwenqubo yokugcina kufanele kwenziwe ngokuhambisana nezinga, futhi ukunemba kungahlangabezana nezidingo zokwenziwa kwe-CMM.Ukunemba okuphezulu kwezingxenye zegwadle ezisetshenziswa ku-CMM, kulapho kukhuphuka khona ukunemba kokulinganisa uma kugcinwa kahle ekusetshenzisweni kwansuku zonke.
Ngamafuphi, ukunemba kanye nekhwalithi ephezulu yezingxenye zegwadle ibalulekile ekusebenzeni kokulinganisa kwe-CMM, futhi ukunaka le mininingwane lapho kukhiqizwa i-CMM kuwukhiye wokuqinisekisa ukunemba nokuzinza kwesilinganiso.Njengoba izingxenye ezihlukahlukene zesakhiwo se-CMM zenziwe nge-granite, imabula namanye amatshe, lapho ikhwalithi izinzile, ukusetshenziswa kwesikhathi eside noma ukulinganisa kuhlu olubanzi lwezinguquko zokushisa kungaqinisekisa ukuthi ukunemba kuzinzile, ukuze kuqinisekiswe ukuthi ukunemba nokuthembeka kokukhiqizwa nokukhiqiza.
