Utyale imali kumatshini wokulinganisa we-coordinate osemgangathweni ophezulu. Isoftware ilinganisiwe. Iiprobes ziqinisekisiwe. Sekunjalo, imilinganiselo yakho iyahamba. Hayi kakhulu—yi-micron nje apha, isiqingatha se-micron phaya. Kodwa kwihlabathi le-metrology echanekileyo kakhulu, loo hamba ngumahluko phakathi kokupasa nokusilela, phakathi komgangatho kunye nokuphinda usebenze, phakathi kwenzuzo kunye ne-scrap.
Yintoni iThermal Drift, Ngokwenene?
Ukushukuma kobushushu kwenzeka xa utshintsho lobushushu lubangela ukuba izinto zesakhiwo senkqubo yokulinganisa zande okanye zinciphe ngokungalinganiyo.Izinto zeCMM—isakhelo, izikali, izikhokelo, okanye isiseko—zikhula ngokungalinganiyo, zizisa ukugqwetheka kwejometri okukhokelela kwiimpazamo zokulinganisa.
Ingxaki ayibonakali kuba ayibonakali. Awunakuyibona i-9°C vertical temperature granite lintel, kodwa inokuvelisa utshintsho oluthe ngqo lobude obubonakalayo ngesantya esimalunga ne-1 μm nge-degree Celsius. Kwi-nanometer-level metrology, loo nto imbi kakhulu.
Kwanomlinganiselo wobushushu obuncinci obufunekayo belebhu ye-metrology—ngokuvamile i-20°C ± 0.5°C—unokubangela uxinzelelo olwaneleyo lobushushu kwizakhiwo zesinyithi ukuze kubangele ukushukuma okukhulu kokulinganisa. Intsimbi ine-CTE ephindwe kabini kuneyegranite. I-aluminium ine-CTE ephindwe kathathu. Xa ubushushu begumbi bujikeleza—njengoko busenza nakweyiphi na indawo yokwenyani—izinto zesinyithi ziyanda kwaye zinciphe ngamanani ahlukeneyo kunesiseko segranite, nto leyo edala ukungaqiniseki komlinganiselo okubangelwa kukufundwa ngakunye.
Kutheni iGranite iyisihlangu sobushushu
Isisombululo asikokusebenzisa ii-algorithms zokunciphisa ubushushu ngendlela eqatha. Sisiseko esingashukumiyo kwasekuqaleni.
I-CTE ephantsi kakhulu yeGranite inciphisa utshintsho olubonakalayo, igcina ubudlelwane obubalulekileyo bejometri phakathi kwee-axis zeCMM kunye nenxalenye elinganisiweyo. I-granite yethu emnyama ye-ZHHIMG®, enobunzima bayo obuyi-≈3100 kg/m³, inika uzinzo lobushushu oludlula uninzi lwee-granite ezimnyama zaseYurophu naseMelika. Ubunzima obukhulu bobushushu besiseko segranite busebenza njengesinki sobushushu esikhulu esingenamsebenzi, sinciphisa ukuguquguquka kobushushu kwaye sigcina imeko-bume engashushu kuyo yonke ivolumu yokulinganisa.
Kodwa izinto zokwakha zodwa azanelanga. Indawo engqongileyo ibaluleke kakhulu.
Ubunjineli Bendawo Ezinzileyo Ngobushushu
Kwi-ZHHIMG®, sithathe uzinzo lobushushu saya kwinqanaba lezoshishino. Indawo yethu yokusebenzela enobushushu obungaguqukiyo obuziimitha ezili-10,000 kunye nokufuma yakhiwe kwisiseko sekhonkrithi esiqinileyo esinobukhulu obuyi-1000mm. Indawo yokusebenzela ijikelezwe yimijelo yokulwa nokungcangcazela enobubanzi obuyi-500mm kunye nobunzulu obuyi-2000mm. Ngaphakathi, iikhreyini ezizodwa ezingashukumiyo zisebenza ukugcina indawo engenangcangcazelo ngokupheleleyo kwaye izinzile kubushushu.
Kodwa siyaqhubeka. Sigcina igumbi lokucoca elizinikeleyo elinobushushu obungaguqukiyo, elinomswakama ongaguqukiyo elilinganisa iindawo zokwenza izixhobo ze-semiconductor—eyenzelwe ngokukodwa ukuhlanganiswa kwezixhobo zegranite. Oku akupheleli nje ekugcineni ubushushu bungama-20°C. Kumalunga nokususa ii-thermal gradients kuzo zonke izinto ezinkulu zesakhiwo ngexesha lelona nqanaba libalulekileyo lemveliso: ukuhlanganiswa kokugqibela kunye nokuhlolwa.
Ikhonkco Lokulinganisa
Kakade ke, awunakulawula into ongenakukwazi ukuyilinganisa. Yiyo loo nto ilebhu yethu ye-metrology ixhotyiswe ngezixhobo zokulinganisa eziphambili kwihlabathi: ii-German Mahr dial gauges (isisombululo se-0.5 μm), ii-Mitutoyo micrometers kunye nee-digital calipers, amanqanaba e-elektroniki e-Swiss WYLER, kunye nee-interferometers ze-laser zaseBritish Renishaw. Zonke izixhobo zinezatifikethi zokulinganisa ezivela kwiJinan Institute of Metrology kunye neShandong Institute of Metrology—kwaye zonke iimveliso zokulinganisa zinokulandelwa emva kwiNational Institute of Metrology yaseTshayina.
I-Human Element
Nantsi into engayixelelwanga zizifundo: kwanezixhobo ezilungileyo kunye nendawo ezinzileyo azinakuthatha indawo yesigqibo somntu. Iingcali zethu zokugaya, nganye inamava angaphezu kweminyaka engama-30 yokubopha ngesandla, zinokumisela ngokuthe ngqo ukuba zingaphi ii-microns zezinto abazisusayo nge-stroke enye. Abathengi bethu bazibiza ngokuba “ziinqanaba ze-elektroniki ezihambayo”. Abalandeli nje inkqubo; bayaziva izinto, beva utshintsho lokumelana olubonisa utshintsho oluncinci kwi-flatness.
Olu luhlu lwempendulo oluchukumisekayo—oludibanisa iziseko zophuhliso ezikumgangatho wehlabathi kunye nengqiqo yomntu engenakutshintshwa—luqinisekisa ukuba yonke into yegranite ye-ZHHIMG®, ukusuka kwiipleyiti zomphezulu ukuya kwiibheringi zomoya, ihlangabezana nemigangatho yehlabathi efunekayo.
Iingcebiso Ezisebenzayo Kubathengi
Ukuba umthengisi ucaphula igama elithi “granite” ngaphandle kokuchaza ukuba lilitye elimbiweyo okanye yiminerali ephoswe kuyo, buza ngokuthe ngqo—umahluko wexabiso, i-geometry enokufikelelwa, kunye neprofayili yozinzo lwexesha elide zahlukile ngokwaneleyo kangangokuba umahluko kufuneka ube yinxalenye yayo nayiphi na i-technical spec sheet. Ngokukodwa kumsebenzi we-metrology ochanekileyo, cela ubuninzi bokwenyani, i-CTE, kunye nokunyamezelana kokuthe tyaba okufezekisiweyo—hayi igama lezinto kuphela.
Kuba kwihlabathi lokulinganisa inqanaba le-nanometer, ukushukuma kobushushu akuyongxaki uyisombulula ngesoftware. Yingxaki oyithintelayo ngezinto ezifanelekileyo, indawo efanelekileyo, kunye nabantu abafanelekileyo.
