Isimo se-dimensional metrology siye sashintsha kakhulu eminyakeni engamashumi amabili edlule, siqhutshwa yingcindezi engapheli yokunciphisa izikhathi zomjikelezo wokuhlola, ukuthuthukisa ukuguquguquka kokukhiqiza, nokuletha amakhono okulawula ikhwalithi ngqo endaweni yokukhiqiza. Lapho lapho konke ukulinganisa ngokunemba kwakudinga ukuthutha izingxenye ziye emalabhorethri alawulwa amazinga okushisa anemishini yokulinganisa emikhulu efana nebhuloho, izindawo zokukhiqiza zanamuhla ziya ngokuya zifuna izixazululo zokulinganisa ezingaya endaweni yokusebenza kunokuba zidinge ukuthi indawo yokusebenza iye ohlelweni lokulinganisa. Ngaphambili kwalolu shintsho kumi umshini wokulinganisa ophathwa ngesandla, ithuluzi lokulinganisa eliphathekayo elishintshe kakhulu indlela abakhiqizi ababhekana ngayo nokuhlolwa kobukhulu. Noma kunjalo, njengoba la madivayisi eletha ukuguquguquka okungakaze kubonwe emisebenzini yokulinganisa, aphinde alethe izinselele ezintsha eziqokomisa ukubaluleka okuhlala njalo kwezimiso eziyisisekelo ze-metrology, okuhlanganisa nesidingo esibalulekile sepuleti lokulinganisa njengendawo yokubhekisela.
Uhambo oluya ekulinganisweni okuphathekayo lwaqala ngokuqaphela ukuthi imishini yokulinganisa evamile, naphezu kokunemba kwayo okungavamile kanye nekhono, yabeka imingcele emikhulu emisebenzini yokukhiqiza. Izingxenye ezidinga ukuhlolwa kwadingeka zisuswe emishinini yokukhiqiza, zithuthwe ziye emalabhorethri azinikele e-metrology, zijwayele izimo zemvelo ezilawulwayo, zilungiswe ngendlela efanele, zikalwe ochwepheshe abaqeqeshwe, bese zibuyiselwa ekukhiqizeni. Ekukhiqizeni okuphezulu okunezingxenye ezimbalwa, le nqubo ingalungiswa futhi ifakwe ezinhlelweni zokukhiqiza. Kodwa ezitolo zemisebenzi ezisingatha ama-geometri ezingxenye ezahlukahlukene, abakhiqizi abakhiqiza izinhlangano ezinkulu ezingenakunyakaziswa kalula, noma imisebenzi edinga impendulo esheshayo phakathi komshini nokulinganisa, imodeli yendabuko yadala izithiyo ezazivimbela ukuphuma kanye nezikhathi zokuhola ezandisiwe.
Umshini wokulinganisa ophathwa ngesandla uvele njengempendulo yalezi zithiyo, unikeza amandla okulinganisa ngefomethi ephathekayo engafakwa noma kuphi lapho kudingeka khona ukulinganisa. Ama-CMM anamuhla aphathwa ngesandla asebenzisa ubuchwepheshe obuhlukahlukene ukuze afinyelele ukuphatheka kwawo kanye nokuguquguquka kwawo. Izinhlelo zokulandelela ezibonakalayo zisebenzisa amakhamera kanye nezibonisi ukuze zihlukanise indawo yama-probe angenantambo esikhaleni esinezilinganiso ezintathu, okwenza izilinganiso zilinganiswe ngaphandle kwemingcele yemishini yezakhiwo zebhuloho noma ze-gantry zendabuko. Izinhlelo zengalo ezihlanganisiwe ezinamajoyinti amaningi ajikelezayo zivumela opharetha ukuthi babeke amathiphu e-probe cishe kunoma yikuphi ukuqondiswa, bafinyelele izici ezingeke zifinyeleleke emishinini ye-geometry eqondile. Izinhlelo ezisekelwe ekuboneni zilandelela ama-probe aphathwayo ngama-array ekhamera ayinkimbinkimbi, zigcina ukunemba kokulinganisa ngenkathi zivumela inkululeko ephelele yokuhamba eduze kwento yokusebenza.
Okuhlukanisa imishini yokulinganisa ephathwa ngesandla esebenza kahle ngempela nemizamo yokulinganisa ephathwayo yangaphambilini yikhono layo lokugcina ukunemba kwebanga le-metrology naphezu kwezinselele ezikhona ezindaweni zasesitolo. Ukushintshashintsha kwezinga lokushisa, ukudlidliza okuvela emishinini eseduze, izimo zokukhanya ezihlukile, kanye nobuchwepheshe bomqhubi konke kuveza imithombo engaba khona yephutha lokulinganisa elizosuswa noma lincishiswe elabhorethri elawulwayo. Ama-CMM aphathwa ngesandla athuthukisiwe abhekana nalezi zinselele ngokubhekisela okunamandla, lapho izibonisi ezibonakalayo ezibekwe phezu noma eduze kwento yokusebenza ziqhubeka nokulandelela noma yikuphi ukunyakaza okuhlobene phakathi kwesistimu yokulinganisa nengxenye elinganiswayo. Lokhu kuvumela uhlelo ukuthi lukhokhele ukuphazamiseka kwemvelo ngesikhathi sangempela, lugcine ukunemba ngisho nalapho izimo zingekho kahle.
Umthelela osebenzayo waleli khono emisebenzini yokukhiqiza ube mkhulu kakhulu. Ochwepheshe bekhwalithi manje sebengalinganisa izinhlangano ezinkulu endaweni, basuse isidingo sokuhlukaniswa nokuhlanganiswa kabusha obekungadingeka ukuletha izingxenye ku-CMM ehleliwe. Abasebenzi bokukhiqiza bangaqinisekisa ukuhambisana kobukhulu ngokushesha ngemva kokusebenza komshini, banciphise ingozi yokukhiqiza inani elikhulu lezingxenye ezingabekezeleleki ngaphambi kokuba inkinga itholakale. Onjiniyela bokuklama bangathatha idatha yobukhulu kusukela kuma-prototypes kanye nezingxenye zesikhathi esidlule zobunjiniyela obubuyela emuva ngaphandle kokubambezeleka kanye nokufakwa kwemishini yokulinganisa elebhu. Umshini wokulinganisa we-coordinate ophathwayo uguqule ukulinganisa kusuka emsebenzini we-bottleneck waba yinto ehlanganisiwe yenqubo yokukhiqiza.
Kodwa-ke ukuguquguquka okwenza ama-CMM aphathwayo abe yigugu kangaka kudala nezinselele abasebenzisi okumele baziqonde futhi bazixazulule. Umshini wokulinganisa wendabuko wohlobo lwebhuloho uthola ukunemba kwawo esakhiweni esiqinile esifakwe esisekelweni esikhulu, ngokuvamile ipuleti lobuso le-granite elihlinzeka ngokuqina kobukhulu kanye nokunciphisa ukudlidliza. Ukulinganiswa komshini kanye nesinxephezelo samaphutha kusekelwe ekucabangeni ukuthi lesi sakhiwo sokubhekisela sihlala sizinzile ngokuhamba kwesikhathi. Lapho kuthathwa izilinganiso, zenziwa maqondana nohlelo lokuhlanganisa lomshini, oluchazwa ngokwalo isakhiwo somzimba somshini futhi luqinisekiswe ngokulinganiswa okuvamile ngokumelene nezindinganiso ezilandelekayo.
Umshini wokulinganisa ophathwa ngesandla, ngokuphambene, awulethi isakhiwo sokubhekisela esinjalo esivamile ekulinganisweni. Uhlelo lokuhlela lokulinganisa kumele lusungulwe kabusha kuseshini ngayinye yokulinganisa, ngokuvamile ngokuvumelanisa nezici zokubhekisela emsebenzini ngokwawo noma ezintweni zokubhekisela zangaphandle ezibekwe ngenhloso. Lo mehluko oyisisekelo unemiphumela ejulile ekunembileni kokulinganisa, ukulandeleka, kanye nenqubo yokulinganisa iyonke. Ngaphandle kwendiza yokubhekisela ezinzile eqinisekiswe ngokulinganisa okufanele, izilinganiso ezithathwe ngedivayisi ephathwayo zingase zihambisane ngaphakathi kodwa zingalandeleki ezindinganisweni eziqashelwayo.
Yilapho ipuleti lokulinganisa ubuso liba khona elibalulekile ekusebenzeni okuphumelelayo kwe-CMM ephathwa ngesandla. Naphezu kobuchwepheshe obuthuthukisiwe obuhlanganiswe ezinhlelweni zokulinganisa eziphathwayo zesimanje, zisadinga amazinga okubhekisela lapho izilinganiso zazo zingaqinisekiswa futhi zilinganiswe khona. Ipuleti lokulinganisa ubuso, eliqondile libe yi-flat engavamile futhi lilinganiswe ngokwezindinganiso eziqashelwayo njenge-ISO 8512 noma i-ASME B89.3.7, linikeza lokhu kubhekisela ngqo. Ipuleti lokulinganisa ubuso elilinganiswe kahle lisebenza njengendawo eyisisekelo yokubhekisela lapho umshini wokulinganisa ophathwa ngesandla ungaqinisekisa khona ukunemba kwawo futhi usungule ukulandelelwa kwezindinganiso zokulinganisa zikazwelonke.
Ubudlelwano phakathi kwama-CMM aphathwa ngesandla kanye namapuleti okulinganisa ubuso bubonakala ngezindlela eziningana ezisebenzayo. Ngaphambi kokuqala imisebenzi yokulinganisa okubucayi, ochwepheshe bavame ukwenza ukuhlolwa kokuqinisekisa ngokulinganisa izinto zobuciko zobukhulu obaziwayo epuletini lokulinganisa ubuso elilinganisiwe.
