Ukulandeleka kwemetrological kwezixhobo ezahlukeneyo zokulinganisa ngokuchanekileyo kunye noomatshini kuxhomekeke kwiireferensi ezibonakalayo ezizinzileyo nezithembekileyo. Emva kokusebenza ixesha elide, ukuchaneka kwejometri kwezixhobo ezininzi zokuhlola kunye nezixhobo zoomatshini kuya kuba nokushukuma okuncinci. Imbuyekezo yesoftware eqhelekileyo inokulungisa inxalenye yeempazamo kuphela. Ukuqinisekisa imeko yokwenyani yejometri yezixhobo, iireferensi ezibonakalayo ziyafuneka ukuze kuthelekiswe kwaye kuhlolwe. Njengeebhloko zereferensi ezibonakalayo, iityhubhu zegranite ezichanekileyo zibonelela ngeereferensi ezibonakalayo ezibonakalayo kwiimashini zokulinganisa ezilungelelanisiweyo, ii-optical comparators kunye nezixhobo zomatshini ochanekileyo, kwaye zenze ukulinganiswa kunye nokuqinisekiswa kwesikwere, ukufana kunye nobudlelwane bejometri bendawo.
Iibhloko zegeyiji zesinyithi eziqhelekileyo ziyanda kwaye zinciphe ngokuphawulekayo xa kutshintshwe ubushushu. Zithambekele ekuguquguqukeni kwe-dent kunye nokugqwala komphezulu emva kokusetyenziswa okuphindaphindiweyo, kwaye ukuchaneka kwazo kuyabola kancinci kancinci xa zigcinwa ixesha elide. Ngokwahlukileyo koko, ii-granite cubes zinesakhiwo sekristale yeminerali exineneyo ene-thermal expansion coefficient ephantsi kakhulu. Utshintsho olubangelwa kukuguquguquka okuncinci kubushushu be-ambient alunamsebenzi. Okwangoku, izinto ziqhayisa ngokudamba okuphezulu kunye nokumelana okunamandla kokuguquguquka. Ngexesha lokuthuthwa kunye nokulinganiswa kwindawo, iimpembelelo ezincinci aziyi kubangela ukuguquguquka kweplastiki ngokungafaniyo neebhloko zegeyiji zentsimbi, ngoko ke ubudlelwane bejometri phakathi kobuso obuthandathu be-cube bunokugcinwa ixesha elide.
Nangona kunjalo, ityhubhu yereferensi yegranite efanelekileyo ayinakwenziwa ngokusika nokupolisha amatye. Xa ivelisa iibhulokhi zereferensi ezinjalo, i-ZHHIMG ilawula ngokungqongqo umgangatho wezinto eziluhlaza ukusuka kwinqanaba elingenanto kwaye iyawalahla amabhulokhi arhabaxa aneemifantu ezincinci okanye ubume obungafaniyo. Amabhulokhi adlula kunyango lokuguga ixesha elide ukuze akhulule uxinzelelo lwangaphakathi oluseleyo kwaye aphephe ukuguquka kancinci emva kokwenziwa. Ubuso obuthandathu obusebenzayo betyhubhu kunye nokuma okuthe nkqo phakathi kwamacala akufutshane kumhlaba inyathelo ngenyathelo kwindawo yokusebenzela enobushushu obungaguqukiyo, engenaluthuli. Ngokungafaniyo nokwenziwa kwecala elinye kwizinto eziqhelekileyo, iityhubhu zegranite zifuna ukucutshungulwa okudibeneyo kwazo zonke ubuso obuthandathu, ngokutshintshana kokusila kunye nokuhlolwa okuphindaphindiweyo ukuqinisekisa ukuba ukufana kwesibini ngasinye sobuso obuchaseneyo kunye nobukhulu bobuso obukufutshane kuhambelana nemigangatho ngaxeshanye.
Izicelo zokulinganisa zibeka iimfuno ezingqongqo kwiinkcukacha zeetyhubhu zesalathiso. Imiphetho yesalathiso ayisebenzi ukuthintela ukuqhekeka ngexesha lokusetyenziswa kwentsimi. Nje ukuba kuvela iinotshi kwiikona nakwiikona, i-geometric benchmark yebhloko yesalathiso yonke iya kusilela. Emva kokugaywa ngokuchanekileyo kwayo yonke indawo yokusebenza, izixhobo zokulinganisa ngokuchanekileyo zisetyenziselwa ukuqokelela idatha yobuso ngabunye, ukurekhoda iimpazamo zokuthamba kwendawo nganye kunye nokwenza iingxelo zokuhlola ezipheleleyo. Kwiimeko ezifana ne-metrology yelabhoratri, ukujonga rhoqo izixhobo kwindawo kunye nokwamkelwa emva kokulungiswa kwezixhobo, abaqhubi banokuqinisekisa ngokukhawuleza isakhelo se-engile yasekunene sendawo yezixhobo ezineetyhubhu zegranite kwaye bagwebe ukuba iinkqubo ze-shaft zigobile na, zilungisa imida yokuhlawula isoftware ecocekileyo.
Abasebenzisi abaninzi babhidanisa ii-granite reference cubes nezikwere zegranite eziqhelekileyo. Izikwere zisetyenziselwa kakhulu ukuhlola i-plane enye kunye nee-engile zasekunene, ngelixa ii-granite cubes ziireferensi ezimacala mathandathu ezinokubonelela ngeeseti ezininzi zeebhentshi ezithe nkqo nezilinganayo ngaxeshanye kwaye zixhasa ukuqinisekiswa kwejometri yendawo enemilinganiselo emininzi. Kwi-calculation eqhelekileyo yezixhobo zokuhlola i-semiconductor, izixhobo zomatshini wokucubungula i-laser kunye nezixhobo zokulinganisa ividiyo ezichanekileyo, zinokufakelwa ngokuphindaphindiweyo ukuze kuthelekiswe ukuqinisekisa ukuhambelana kwee-axes ezintathu zezixhobo. Xa kuthelekiswa neendawo ze-ceramic kunye nezentsimbi, iibhloko ze-granite reference azinangxaki kangako nokuguquguquka okuncinci kubushushu be-workshop kunye nokufuma kwaye zifuna ukulungiswa okulula. Zingasetyenziswa ngokuzinzileyo iminyaka emininzi logama nje iindawo zokusebenza zigcinwa zicocekile. 
I-ZHHIMG inokwenza ngokwezifiso iityhubhu zereferensi zegranite zeenkcukacha ezahlukeneyo ngokweemfuno zemetrological. Imingxunya yokubeka ingafakwa njengoko iceliwe ngabathengi ukuze ivumelane nezixhobo zokufaka kwaye iququzelele ukuqiniswa nokubekwa ngokukhawuleza. Iimveliso ezigqityiweyo ziyahambelana nemigangatho yemetrological yamazwe ngamazwe kuquka i-DIN, i-ASME kunye ne-GB, kwaye ziza nedatha yovavanyo evunyiweyo yi-CNAS. Ngaphandle kobukhulu obuqhelekileyo, sikwavelisa ngokwesiko izinto ezikhethekileyo zereferensi, izikwere zegranite, amaqonga aqhelekileyo kunye nezinye iindawo zereferensi zemetrological, sinikezela ngezisombululo ezipheleleyo zereferensi zomzimba kwiilebhu zemetrology kunye nabavelisi bezixhobo.
Ngamafutshane, iityhubhu zegranite ezichanekileyo kakhulu zingaphezulu kakhulu kuneebhloko zelitye ezilula; zisebenza njengeethwali zokulinganisa ezibonakalayo zokulinganisa i-metrological yezixhobo ezichanekileyo. Ngeempawu zezinto eziguquguqukayo ezisezantsi, ezizinzileyo kakhulu kunye netekhnoloji yokugaya ehambelana nobuso obuninzi, zihlala zibonelela ngeereferensi zejometri ezinokuthenjwa. Zinceda abasebenzisi ukuba bajonge rhoqo ukuchaneka kwejometri yezixhobo, baqinisekise ukulandeleka kwedatha yokulinganisa kwaye bagcine umgangatho we-metrological wokwenziwa ngokuchanekileyo.
