Esimweni sokukhiqiza sanamuhla, ikhono lokulinganisa ngokunemba okukhulu akuyona nje imfuneko yobuchwepheshe; kuyinsika eyisisekelo yokuqinisekisa ikhwalithi kanye nenzuzo yokuncintisana. Njengoba imikhiqizo iba yinkimbinkimbi kakhulu futhi ukubekezelelana kuncipha kuye ezingeni le-micron, indima yelebhu yokukhiqiza ayikaze ibe yinto ebaluleke kangaka. Ukukhetha amathuluzi okulinganisa ngokunemba afanele kuyisinqumo esibalulekile esithinta yonke into kusukela emijikelezweni yokuthuthukiswa komkhiqizo kuya ezindlekweni zokusebenza zesikhathi eside. Lesi sihloko sihlola izinto ezibalulekile zokukhetha imishini ye-metrology, izinhlobo ezahlukene zamathuluzi atholakalayo, kanye nezitayela ezivelayo ezakha ikusasa lokulinganisa ngokunemba emkhakheni wezimboni.
Isinyathelo sokuqala ekukhetheni amathuluzi okulinganisa afanele ukuhlolwa okuphelele kwezidingo ezithile zenqubo yokukhiqiza. Lokhu kuhilela ukuqonda i-geometry yezingxenye ezikhiqizwayo, izinto ezihilelekile, kanye nezinga lokunemba elidingekayo. Umthetho ovamile wesithupha ku-metrology "uMthetho Weshumi," osikisela ukuthi ithuluzi lokulinganisa kufanele libe neqiniso okungenani izikhathi eziyishumi kunokubekezelela kwengxenye elinganiswayo. Isibonelo, uma ingxenye inokubekezelelana okungu-0.1 millimeters, ithuluzi lokulinganisa kufanele likwazi ukulinganisa kufike ku-0.01 millimeters. Kodwa-ke, njengoba ukubekezelelana kuqhubeka nokuqina, lo mthetho uvame ukusunduzelwa emikhawulweni yawo, kudingeke ukuthi amalabhorethri atshale imali emishinini eyinkimbinkimbi enganikeza isisombululo esidingekayo kanye nokuphindaphindwa.
Ukunemba nokunemba kuvame ukusetshenziswa ngokushintshana, kodwa kumongo webhubhu yokukhiqiza, kunezincazelo ezihlukile nezibaluleke ngokulinganayo. Ukunemba kubhekisela ekutheni isilinganiso siseduze kangakanani nenani langempela, kuyilapho ukunemba, noma ukuphindaphindwa, kubhekisela ekuhambisaneni kwezilinganiso lapho kuthathwa izikhathi eziningi ngaphansi kwezimo ezifanayo. Ithuluzi lingaba nembalo ngaphandle kokuba nembalo, noma libe nembalo ngaphandle kokuba nembalo. Kwibhubhu yokukhiqiza, ithuluzi elifanele yizo zombili. Ukufeza lokhu akudingi nje kuphela imishini esezingeni eliphezulu kodwa futhi nendawo elawulwayo lapho izinto ezifana nokushisa, umswakama, kanye nokudlidliza kulawulwa ngokucophelela. Ukuzinza kwepulatifomu yokulinganisa, evame ukuhlinzekwa ngamapuleti obuso be-granite anembile, nakho kuyisici esibalulekile ekuqinisekiseni ukuthi izilinganiso zinembile futhi ziyaphindaphindwa.
Izinhlobonhlobo zamathuluzi okulinganisa ngokunemba atholakalayo namuhla ziningi kakhulu, kusukela kumathuluzi esandla alula kuya ezinhlelweni ezizenzakalelayo eziyinkimbinkimbi. Ezingeni eliyisisekelo kakhulu kukhona ama-caliper nama-micrometer, ahlala ebalulekile ekulinganisweni okusheshayo, okuqondile kobude, ukujula, nobubanzi. Ngenkathi la mathuluzi esethuthuke kakhulu ngezibonisi zedijithali kanye nokukhishwa kwedatha okungenantambo, asathembele ekhonweni lomqhubi. Ukuze uthole amajiyometri ayinkimbinkimbi kakhulu kanye namazinga aphezulu okunemba, i-Coordinate Measuring Machines (CMMs) isibe yindinganiso yemboni. Ama-CMM asebenzisa i-probe ukuze abambe izixhumanisi ze-X, Y, kanye ne-Z zobuso bengxenye, okuvumela ukulinganiswa kwezimo ze-3D eziyinkimbinkimbi ngokunemba okukhulu. Ukukhetha phakathi kwe-CMM yesandla noma ezenzakalelayo kuncike kunani lezingxenye ezihlolwayo kanye nezinga elidingekayo lokukhishwa.
Eminyakeni yamuva nje, izinhlelo zokulinganisa ezisekelwe ekukhanyeni nasekuboneni ziye zathola ukudonswa okukhulu emalabhorethri okukhiqiza. Lezi zinhlelo ezingezona ezokuthinta zisebenzisa amakhamera anesinqumo esiphezulu kanye nesofthiwe ekhethekile ukulinganisa izingxenye ngaphandle kokuzithinta ngokomzimba. Lokhu kunenzuzo ikakhulukazi ezingxenyeni ezithambile noma eziguquguqukayo ezingase zikhutshazwe yi-probe ebonakalayo. Izinhlelo ze-optical nazo ziyakwazi ukulinganisa izinkulungwane zamaphuzu ngemizuzwana embalwa, okwenza zibe zilungele ukuhlolwa okusheshayo ezindaweni zokukhiqiza. Njengoba ubuchwepheshe bezinzwa buqhubeka nokuthuthuka, umugqa phakathi kokulinganisa okuthintana nokungekho kokuthintana uyafiphala, kanti ama-CMM amaningi anamuhla anikeza womabili amakhono endaweni eyodwa.
I-metrology yokwakheka kwendawo ingenye indawo ebalulekile yokugxila kumalebhu okukhiqiza. Ukuphela kwendawo yengxenye kungaba nomthelela omkhulu ekusebenzeni kwayo, kuthinte izici ezifana nokungqubuzana, ukuguguleka, kanye nokuphila kokukhathala. Amathuluzi anjenge-profilometers kanye nabahloli bokuhlubuka kwendawo asetshenziswa ukukala iziqongo ezincane nezigodi zobuso. Ezimbonini ezifana nokukhiqizwa kwezindiza kanye namadivayisi ezokwelapha, lapho ubuqotho bobuso bubaluleke kakhulu, la mathuluzi abalulekile ekuqinisekiseni ukuthi izingxenye ziyahlangabezana nezimfuneko ezidingekayo. Ikhono lokuhlukanisa ukuthungwa kwendawo ku-3D nalo liya ngokuya livame, okunikeza ukuqonda okuphelele kokuthi ingxenye izoziphatha kanjani ekusetshenzisweni kwayo okuhlosiwe.
Ukuhlanganiswa kobuchwepheshe bedijithali mhlawumbe kuyindlela ebaluleke kakhulu emhlabeni wokulinganisa ngokunemba. Ukwanda kwe-Industry 4.0 kuholele ekuthuthukisweni kwamathuluzi okulinganisa "ahlakaniphile" angaxhumana neminye imishini nezinhlelo efektri. Lokhu kuxhumana kuvumela ukuqoqwa kwedatha ngesikhathi sangempela kanye nokuhlaziywa, okuvumela abakhiqizi ukuthi babone izitayela nezinkinga ezingaba khona ngaphambi kokuba ziholele ekulahlekeni noma ekusetshenzisweni kabusha. I-metrology yedijithali iphinde ikhuthaze ukudalwa "kwamawele edijithali," okuyizithombe ezibonakalayo zezingxenye zomzimba. Ngokuqhathanisa idatha elinganisiwe yengxenye newele layo ledijithali, abakhiqizi bangathola ukuqonda okujulile ngokusebenza kwezinqubo zabo zokukhiqiza futhi benze izinqumo eziqhutshwa idatha ukuthuthukisa ikhwalithi kanye nokusebenza kahle.
Ukulandelela kanye nokulinganisa nakho kubalulekile lapho ukhetha amathuluzi okulinganisa. Ukuqinisekisa ukuthi izilinganiso ziyasebenza, kumele zilandelelwe ngokwezinga eliqashelwayo likazwelonke noma lamazwe ngamazwe. Lokhu kudinga ukulinganisa njalo yonke imishini yokulinganisa yilabhorethri eqinisekisiwe. Lapho ukhetha amathuluzi, kubalulekile ukucabangela ukulula kokulinganisa kanye nokutholakala kwezinsizakalo zokusekela ezivela kumkhiqizi. Ukutshala imali kumathuluzi avela kumikhiqizo ethembekile enikeza izinhlelo zokulinganisa eziphelele kanye nokulungisa kungasindisa isikhathi nemali eningi elebhu ngokuhamba kwesikhathi. Ngaphezu kwalokho, ukusetshenziswa kwamabhulokhi e-gauge kanye nezinye izindinganiso zokubhekisela ngaphakathi kwelabhorethri kuvumela ukuhlolwa kwangaphakathi okuvamile ukuqinisekisa ukuthi imishini ihlala ngaphakathi kwemingcele yayo yokunemba ecacisiwe.
Ekuphetheni, ukukhetha amathuluzi okulinganisa ngokunemba afanele kuwumsebenzi oyinkimbinkimbi kodwa obalulekile kunoma yiliphi ilabhorethri yokukhiqiza. Kudinga ukuqonda okujulile ngezidingo zokulinganisa, umehluko ocacile phakathi kokunemba nokunemba, kanye nokwazi ngezinhlobo ezahlukene zamathuluzi nobuchwepheshe obutholakalayo. Ngokutshala imali emishinini efanele nokugcina indawo elawulwayo, abakhiqizi bangaqinisekisa ukuthi imikhiqizo yabo ihlangabezana nezindinganiso eziphakeme kakhulu zekhwalithi nokuthembeka. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, indima ye-metrology izohlanganiswa kakhulu enkambisweni yokukhiqiza, inikeze idatha kanye nokuqonda okudingekayo ukuze kuqhutshwe ukusungula izinto ezintsha kanye nokwenza kahle emkhakheni wezimboni. Amathuluzi afanele awawona nje amathuluzi okulinganisa; ayizihluthulelo zokuvula amandla aphelele okukhiqiza kwanamuhla.
Isici somuntu ekulinganisweni okunembile singenye into engenakulibaleka. Ngisho namathuluzi athuthuke kakhulu adinga opharetha abanekhono abaqonda izimiso ze-metrology kanye nokuqonda kwemishini. Ngakho-ke ukuqeqeshwa nemfundo kuyizingxenye ezibalulekile zelebhu yokukhiqiza ephumelelayo. Lapho ukhetha amathuluzi, kubalulekile ukucabangela isikhombikubona somsebenzisi kanye nokulula kokusetshenziswa. Amaphakheji esofthiwe yesimanje yama-CMM nezinhlelo zokubona aseye aba yinkimbinkimbi ngokwengeziwe, anezikhombikubona zezithombe kanye nezici zokuhlela ezenzakalelayo ezinciphisa ingozi yephutha lomqhubi. Kodwa-ke, isisekelo esiqinile ezisekelweni zokulinganisa—njengokuqonda imiphumela ye-parallax, ukubaluleka kokulungiswa kwezingxenye okufanele, kanye nomthelela wezinto zemvelo—kusalokhu kubalulekile. Ilebhu etshala imali kokubili kumathuluzi asezingeni eliphezulu kanye nokuthuthukiswa kobungcweti kwabasebenzi bayo izohlala inomkhawulo wokuncintisana.
Ngaphezu kwalokho, izindleko zesikhathi eside zobunikazi kufanele zibe yingxenye ebalulekile yenqubo yokwenza izinqumo. Intengo yokuqala yokuthenga ithuluzi lokulinganisa ngokunembile iyingxenye eyodwa nje yokutshalwa kwezimali okuphelele. Ezinye izinto okufanele uzicabangele zifaka phakathi izindleko zokulungisa, ukulinganisa, izibuyekezo zesofthiwe, kanye nokulungiswa okungenzeka. Amanye amathuluzi angase abe nezindleko eziphansi kusengaphambili kodwa adinga ukulinganisa okuvamile noma abe nezidingo zokulungisa eziphakeme. Kubalulekile futhi ukucabangela ukuguquguquka kwemishini. Ithuluzi elingasetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza futhi elingathuthukiswa kalula njengoba ubuchwepheshe buthuthuka lizonikeza imbuyiselo engcono ekutshalweni kwezimali esikhathini sokuphila kwalo. Abakhiqizi kufanele bafune imishini enikeza umklamo we-modular noma engahlanganiswa nezinye izinhlelo, okuvumela ilebhu ukuthi ikhule futhi ivumelane nezidingo ezishintshayo.
Indawo engokoqobo yelebhu ngokwayo idlala indima ebalulekile ekusebenzeni kwamathuluzi okulinganisa ngokunembile. Njengoba kushiwo ngaphambili, izinga lokushisa kanye nomswakama kungathinta kakhulu ukunemba kwezilinganiso.
