Ezweni elikhethekile lokukhiqiza izinto ezisindayo—lapho kuzalwa khona amaphiko ezindiza, ama-hub e-wind turbine, kanye ne-chassis yezimoto—isikali esibonakalayo sengxenye sivame ukuba yisithiyo esikhulu ekuqinisekisweni kwayo. Lapho ingxenye idlula amamitha amaningana, izithiyo zokulinganisa zikhuphuka ngokushesha. Akusekho nje ngokubamba iphutha; kumayelana nokuqinisekisa ukuzinza komjikelezo wokukhiqiza wezigidi zamaRandi. Lokhu kuholele abaholi abaningi bemboni ukuthi babuze: Sikugcina kanjani ukunemba kwebanga lelebhu lapho umsebenzi ukhulu njengemoto? Impendulo itholakala ekwakhiweni okuyisisekelo kwendawo yokulinganisa, ikakhulukazi ukushintshela ezinhlelweni ze-gantry ezisindayo kanye nezinto eziyinkimbinkimbi ezizisekelayo.
Ukuqonda umehluko phakathi kwesisombululo se-cmm kanye nokunemba kuyisinyathelo sokuqala sokuqonda i-metrology enkulu. Ekuhlanganisweni okukhulu, ukulungiswa okuphezulu kuvumela inzwa ukuthi ibone ukuhlukahluka okuncane kakhulu kobuso, kodwa ngaphandle kokunemba okuphelele, lawo maphuzu edatha empeleni "alahlekile esikhaleni." Ukunemba yikhono lesistimu lokukutshela ngqo ukuthi lelo phuzu likuphi ohlelweni lokuhlanganisa lomhlaba wonke uma kuqhathaniswa nemodeli ye-CAD. Kumishini enefomethi enkulu, ukufeza lokhu kudinga ubudlelwano obuvumelanayo phakathi kwezinzwa ze-elekthronikhi kanye nohlaka lomzimba lomshini. Uma uhlaka luguquguquka noma lusabela ekushiseni, ngisho nenzwa yesisombululo esiphezulu emhlabeni izobuyisa idatha enganembile.
Ukuxazulula lokhu, ubunjiniyela beIzingxenye zomshini wokulinganisa izinhlangothi zombilisekuyindawo ebalulekile kubahlinzeki be-metrology abasezingeni eliphezulu. Ngokusebenzisa umklamo onamakholomu amabili noma omabili, le mishini ingahlola izinhlangothi zombili zomsebenzi omkhulu ngesikhathi esisodwa noma iphathe izingxenye ezibanzi kakhulu ebezingenakwenzeka nge-CMM yebhuloho yendabuko. Le ndlela elinganayo ayigcini nje ngokuphindwe kabili umthamo; ihlinzeka ngomthwalo olinganiselayo wemishini, okubalulekile ekugcineni ukuphindaphindeka kwesikhathi eside. Uma ulinganisa ingxenye engamamitha amahlanu ubude, ukuvumelanisa kwemishini kwalezi zingxenye ezimbili yikho okuqinisekisa ukuthi "isandla sobunxele siyazi ukuthi isandla sokudla senzani," okunikeza i-twin yedijithali ehlangene nenembile kakhulu yengxenye.
Isikhali esiyimfihlo ekufinyeleleni lokhu kuzinza ukusetshenziswa kwe-granite enembile ezakhiweni zoMshini Wokulinganisa Ohlangothini Olubili. Nakuba insimbi ne-aluminium kunendawo yazo ekusetshenzisweni okulula, zisengozini "yokukhukhuleka kokushisa" - ukunwebeka nokuncipha ngokushintsha okuncane kokushisa kwefektri. I-granite, ikakhulukazi i-gabbro emnyama esezingeni eliphezulu, iguga ngokwemvelo eminyakeni engaphezu kwezigidi, okwenza iqine kakhulu. I-coefficient yayo ephansi yokwanda kokushisa kanye nezakhiwo zokudlidliza okuphezulu kusho ukuthi "iphuzu le-zero" lomshini lihlala likhona, ngisho nasendaweni yokuthenga engalawulwa yisimo sezulu. Ezweni le-metrology ye-elite, i-granite ayiyona nje isisekelo; iyisiqinisekiso esithule sawo wonke ama-micron alinganisiwe.
Ngemisebenzi "emikhulu" ngempela,Umbhede Womshini Wokulinganisa Omkhulu We-Gantryimelela isiqongo sokulinganisa kwezimboni. Lezi zibhede zivame ukufakwa phansi kwefektri, okuvumela izingxenye ezisindayo ukuthi ziqhutshwe noma zikrwelwe ngqo kumthamo wokulinganisa. Ubunjiniyela bale mibhede buyisenzo sobunjiniyela bezokwakha kanye nobemishini. Kumelwe zibe ziqinile ngokwanele ukusekela amashumi amatani esisindo ngaphandle kokuphambuka okuncane kakhulu. Ngokuhlanganisa izinsimbi zokugaya ngqo embhedeni oqinile, oqiniswe nge-granite, abakhiqizi bangafinyelela ukunemba kwevolumu okwakugcinelwe ngaphambili amathuluzi elabhorethri amancane. Lokhu kuvumela inqubo yokuhlola "yokuma okukodwa" lapho ukuphonswa okukhulu kungaqinisekiswa, kusetshenziswe ngomshini, futhi kuqinisekiswe kabusha ngaphandle kokushiya indawo yokukhiqiza.
Ezinkampanini ezisebenza emkhakheni wezindiza namandla eNyakatho Melika naseYurophu, leli zinga legunya lobuchwepheshe liyimfuneko yokwenza ibhizinisi. Abafuni ithuluzi "elihle ngokwanele"; bafuna umlingani oqonda i-physics yokulinganisa ngezinga. Ukusebenzisana kwezinzwa ezinesinqumo esiphezulu, ukunyakaza okubili, kanye ne-inertia yokushisa ye-granite enembile kudala indawo lapho ikhwalithi ihlala njalo, hhayi into eguquguqukayo. Njengoba sicindezela imingcele yalokho abantu abangakwakha, imishini esiyisebenzisayo ukulinganisa lezo zidalwa kumele yakhiwe ngokucophelela okukhulu. Ekugcineni, ukulinganisa okunembile kakhulu akuyona nje inombolo—kuyisisekelo sokuphepha nokusungula izinto ezintsha ezweni elifuna ukuphelela.
