Utshale imali emshinini wokulinganisa osezingeni eliphezulu. Isofthiwe iyalinganiswa. Ama-probe aqinisekisiwe. Noma kunjalo, izilinganiso zakho ziyashintshashintsha. Hhayi kakhulu—i-micron nje lapha, isigamu se-micron laphaya. Kodwa ezweni le-metrology enembile kakhulu, lokho kushintshashintsha umehluko phakathi kokudlula nokwehluleka, phakathi kwekhwalithi nokusebenza kabusha, phakathi kwenzuzo kanye nokulahlekelwa.
Kuyini Ngempela Ukukhukhuleka Kwe-Thermal?
Ukukhukhuleka kokushisa kwenzeka lapho ukushintshashintsha kwezinga lokushisa kubangela ukuthi izingxenye zesakhiwo zesistimu yokulinganisa zande noma zinciphe ngokungalingani.Izingxenye ze-CMM—uhlaka, izikali, iziqondiso, noma isisekelo—zinwebeka ngokungalingani, zethula ukuhlanekezela kwejometri okuholela emaphutheni okulinganisa.
Inkinga iyimfihlo ngoba ayibonakali. Awukwazi ukubona i-gradient yokushisa eqondile engu-9°C phezu kwe-lintel ye-granite, kodwa ingadala ushintsho oluqondile lobude obubonakalayo ngesilinganiso esingaba ngu-1 μm nge-degree Celsius. Ku-metrology yezinga le-nanometer, lokho kuyinhlekelele.
Ngisho nobubanzi obuncane bokushisa obudingekayo belebhu ye-metrology—ngokuvamile engu-20°C ± 0.5°C—bungadala ukucindezeleka okwanele kokushisa ezakhiweni zensimbi okubangela ukuzulazula okukhulu kokulinganisa. Insimbi ine-CTE cishe kabili kune-granite. I-Aluminium ine-CTE cishe ngokuphindwe kathathu. Lapho izinga lokushisa legumbi lijikeleza—njengoba lenza kunoma yisiphi isakhiwo sangempela—izingxenye zensimbi ziyanda futhi zinciphe ngamazinga ahlukene kunesisekelo se-granite, okudala ukungaqiniseki kokulinganisa okufakwe kukho konke ukufundwa.
Kungani iGranite iyisivikelo sokushisa
Isixazululo asiyona indlela enamandla kakhulu yokunciphisa izinga lokushisa. Kuyisisekelo esingashukumi kwasekuqaleni.
I-CTE ephansi kakhulu ye-Granite inciphisa ushintsho lobukhulu, igcina ubudlelwano obubalulekile bejometri phakathi kwezingqimba ze-CMM kanye nengxenye elinganisiwe. I-granite yethu emnyama ye-ZHHIMG®, enobukhulu bayo obungu-≈3100 kg/m³, inikeza ukuzinza kokushisa okudlula iningi lama-granite amnyama aseYurophu naseMelika. Isisindo esikhulu sokushisa sesisekelo se-granite sisebenza njengesinki esikhulu sokushisa esingasebenzi, sinciphisa ukuguquguquka kwezinga lokushisa futhi silondoloze indawo engeyona eshisayo kuyo yonke ivolumu yokulinganisa.
Kodwa izinto zokwakha zodwa azanele. Indawo ezungezile nayo ibaluleke kakhulu.
Ubunjiniyela Bendawo Ezinzile Ngokushisayo
Kwa-ZHHIMG®, sithathe ukuzinza kokushisa saya ezimbonini eziqine kakhulu. Indawo yethu yokusebenzela yokushisa engaguquki engamamitha-skwele ayi-10,000 yakhiwe phezu kwesisekelo sekhonkrithi esiqinile esingu-1000mm ubukhulu. Indawo yokusebenzela izungezwe imisele yokulwa nokudlidliza enobubanzi obungu-500mm kanye nobubanzi obungu-2000mm. Ngaphakathi, ama-crane athule akhethekile asebenza ukugcina indawo engenazo izidlidliza ngokuphelele futhi izinzile ngokwezinga lokushisa.
Kodwa siyaqhubeka. Sigcina igumbi lokuhlanza elizinikele lokushisa okungaguquki, elinomswakama ongaguquki elilingisa izindawo zokukhiqiza imishini ye-semiconductor—eklanyelwe ngqo ukuhlanganiswa kwezingxenye ze-granite. Lokhu akukhona nje ukugcina izinga lokushisa ku-20°C. Kumayelana nokususa ama-gradient okushisa kuzo zonke izingxenye ezinkulu zesakhiwo ngesikhathi sesigaba esibaluleke kakhulu sokukhiqiza: ukuhlanganiswa kokugcina nokuhlolwa.
Uchungechunge Lokulinganisa
Vele, awukwazi ukulawula lokho ongakwazi ukukukala. Yingakho ilebhu yethu ye-metrology ifakwe izinsimbi zokulinganisa ezithuthuke kakhulu emhlabeni: ama-German Mahr dial gauges (isisombululo esingu-0.5 μm), ama-Mitutoyo micrometer kanye nama-caliper edijithali, amazinga kagesi e-Swiss WYLER, kanye nama-interferometer e-laser e-British Renishaw. Yonke insimbi inezitifiketi zokulinganisa ezivela ku-Jinan Institute of Metrology kanye ne-Shandong Institute of Metrology—futhi yonke i-calibration yomkhiqizo ingalandelelwa emuva ku-National Institute of Metrology of China.
Isici Somuntu
Nakhu okungatshelwanga izincwadi: ngisho nemishini engcono kakhulu kanye nendawo ezinzile kakhulu akunakuthatha indawo yokwahlulela komuntu. Ochwepheshe bethu bokugaya, ngamunye onolwazi olungaphezu kweminyaka engama-30 lokushaya ngesandla, banganquma ukuthi bangaki ama-micron ezinto abazisusayo ngokushaya okukodwa. Amakhasimende ethu ababiza ngokuthi “amazinga kagesi ahambayo”. Abalandeli nje inqubo; bazizwa izinto, bezwa izinguquko zokumelana ezibonisa ukushintshashintsha okuncane kakhulu kokuthamba.
Lo mjikelezo wokuphendula othintayo—ohlanganisa ingqalasizinda yezinga lomhlaba nomuzwa womuntu ongenakuphindwa—uqinisekisa ukuthi yonke ingxenye ye-granite ye-ZHHIMG®, kusukela kumapuleti omhlaba kuya kuma-air bearings, ihlangabezana nezindinganiso zomhlaba ezifunwa kakhulu.
Iseluleko Esiwusizo Kubathengi
Uma umhlinzeki ecaphuna igama elithi “granite” ngaphandle kokucacisa ukuthi itshe elimbiwe noma ukubunjwa kwamaminerali, buza ngqo—umehluko wentengo, i-geometry efinyelelekayo, kanye nephrofayili yokuqina kwesikhathi eside kuhlukile ngokwanele kangangokuthi umehluko kufanele ube yingxenye yanoma yiliphi ishidi lemininingwane yobuchwepheshe. Ngomsebenzi we-metrology onembile kakhulu, cela ukubekezelelana kwangempela, i-CTE, kanye nokubekezela kokuthamba okufinyelelwe—hhayi igama lezinto kuphela.
Ngoba ezweni lokulinganisa izinga le-nanometer, ukukhukhuleka kokushisa akuyona inkinga oyixazulula ngesinxephezelo sesofthiwe. Kuyinkinga oyivimbelayo ngezinto ezifanele, indawo efanele, kanye nabantu abafanele.
