Enqubweni yokuhlolwa komkhiqizo, uma kutholakala ukuthi idatha yokuhlola yohlelo olufanayo noma ingxenye efanayo phakathi nokuhlolwa okuningi ihluke kakhulu, okukhiphayo akuhambelani, noma kuhlukile esimweni sangempela sokuhlanganisa, idinga ukuhlolwa. futhi kuhlaziywe ezicini eziningana. Nanka amaphuzu abalulekile.

Embonini yesimanje yokukhiqiza, i-CMM iya ngokuya isetshenziswa enqubweni yokukhiqiza, okwenza umgomo kanye nokhiye wekhwalithi yomkhiqizo uguquke kancane kancane kusukela ekuhlolweni kokugcina kuya ekulawuleni inqubo yokukhiqiza.

Uma usebenzisa umshini wokulinganisa wokuhlanganisa ukuze ukale, uma ukuchezuka kukhulu kakhulu, sicela ulandele indlela elandelayo ukuze uxazulule inkinga.

Inqubo yokusebenza ye-CMM ngokuvamile ihlanganisa ukulungiselela, ukukhetha uhlelo lokulinganisa, imingcele yokulinganisa yokusetha, ukucubungula idatha, ukucutshungulwa kwedatha, ukucutshungulwa kokulandelela.

Kunezinhlobo eziningi ze-CMM probes, ikakhulukazi ihlukaniswe yaba okuhleliwe, ukuzungezisa okwenziwa ngesandla, ukukhomba ngokuzenzakalelayo kokuzungezisa, ukukhomba okuzenzakalelayo kokuzungeza okuzenzakalelayo kanye nesistimu yokuhlonza jikelele.

I-CMM igxile esilinganisweni sejiyomethri esikhaleni esinezinhlangothi ezintathu, kuyilapho ama-profilometer egxila kuphrofayela engaphezulu kanye nobuhwaba. I-CMM ifanele uhla olubanzi lwezinhlelo zokusebenza zezimboni, kuyilapho ama-profilometer egxile kakhulu ekuhlaziyweni kwesici esingaphezulu.

Kulo mzuzu omuhle kakhulu, sibungaza ngokuhlanganyela iminyaka engama-75 kwasungulwa i-People's Republic of China.

Iphutha elihlelekile lomshini wokulinganisa we-coordinate (CMM) lisho ukuchezuka okuhlelekile okubangelwa izici ezifana nokuklanywa, ukukhiqizwa, ukufakwa kanye nokusetshenziswa kwesisetshenziswa ngokwaso phakathi nenqubo yokulinganisa. Lawa maphutha avamise ukubikezelwa futhi ayaguquguquki lapho izilinganiso ziphindaphindwa ngaphansi kwezimo ezifanayo.

Ukuchezuka kwe-dimensional umehluko we-algebraic wobukhulu kukhishwe izilinganiso zabo ezivamile, ezingahlukaniswa ngokuchezuka kwangempela kanye nokuchezuka komkhawulo.

Imboni yenze intuthuko enkulu kusukela ngeminyaka yawo-1960. Ngokukhula kwemishini yokukhiqiza yezimboni, izimboni zezimoto, i-aerospace kanye ne-elekthronikhi, ukuthuthukiswa nokukhiqizwa kwezinto ezihlukahlukene eziyinkimbinkimbi kudinga ubuchwepheshe bokutholwa okuthuthukisiwe kanye namathuluzi, okuboniswa emshinini wokulinganisa wokuhlanganisa emithathu kanye nobuchwepheshe bokulinganisa obuthathu-ntathu oba khona, futhi athuthukiswe ngokushesha futhi athuthukiswa.

Isilinganiso sokuskena sihlukile esilinganisweni se-trigger, umshini wokulinganisa uzothwala umthwalo ongenayo phakathi nayo yonke inqubo, futhi ukusebenza okuguquguqukayo kubaluleke kakhulu kunokusebenza okumile. Umthwalo we-inertial udala ukuwohloka kwesakhiwo somshini wokulinganisa, okunzima ukukubikezela.

Ibanga lokulinganisa le-CMM liyisici esiyinhloko ekukhetheni i-CMM. Uma sihlela ukuthenga umshini wokulinganisa wokudidiyela (CMM), kufanele siqale sazi usayizi ozungezile womkhiqizo, bese sikhetha usayizi we-CMM. Isibonelo, lapho ukhetha umshini wokulinganisa wokuhlanganisa ibhuloho, intengo yesisetshenziswa ilingana nobude be-beam, ngakho-ke sidinga kuphela ukuhlangabezana nebanga lokulinganisa, singalandeli ububanzi obungadingekile.
