Kwicandelo lokulinganisa ngokuchanekileyo, isixhobo sokulinganisa umfanekiso esinobukhulu obumbini sisixhobo esiphambili sokufumana idatha echanekileyo, kwaye amandla okunciphisa ukungcangcazela kwesiseko saso amisela ngokuthe ngqo ukuchaneka kweziphumo zokulinganisa. Xa sijongene nokuphazamiseka kokungcangcazela okungenakuphepheka kwindawo enzima yemizi-mveliso, ukukhethwa kwezinto ezisisiseko kuba yinto ephambili echaphazela ukusebenza kwesixhobo sokulinganisa umfanekiso. Eli nqaku liza kwenza uthelekiso olunzulu phakathi kwegranite kunye nesinyithi esityhidiweyo njengezixhobo ezibini ezisisiseko, lihlalutye umahluko obalulekileyo ekusebenzeni kwazo kokunciphisa ukungcangcazela, kwaye libonelele ngereferensi yokuphucula isayensi kubasebenzisi beli shishini.
Impembelelo yokungcangcazela ekuchanekeni kokulinganisa izixhobo zokulinganisa umfanekiso ezinemilinganiselo emibini
Isixhobo sokulinganisa umfanekiso esinobukhulu obumbini sibamba umzobo wento evavanywayo ngokuxhomekeka kwinkqubo yokufota ye-optical kwaye sifezekisa umlinganiselo wobungakanani ngokubalwa kwesoftware. Ngexesha lale nkqubo, naluphi na ungcangcazelo oluncinci luya kubangela ukuba ilensi inyikime kwaye into elinganiswayo itshintshe, nto leyo ekhokelela ekufiphaleni komfanekiso kunye nokuphambuka kwedatha. Umzekelo, ekulinganisweni kwesithuba sephini yeetships ze-elektroniki, ukuba isiseko asikwazi ukuthintela ngempumelelo ukungcangcazela, iimpazamo zokulinganisa zinokukhokelela ekugwebeni gwenxa komgangatho wemveliso kwaye zichaphazele izinga lemveliso yomgca wonke wemveliso.
Iimpawu zezinto ezibonakalayo zichonga umahluko ekucinezelweni kokungcangcazela
Imida yokusebenza kweziseko zesinyithi esityhidiweyo
Isinyithi esitshisiweyo sisixhobo esisetyenziswa rhoqo kwisiseko sezixhobo zokulinganisa umfanekiso wendabuko kwaye siyathandwa ngenxa yokuqina kwayo okuphezulu kunye nokulula kokusetyenzwa. Nangona kunjalo, ulwakhiwo lwangaphakathi lwekristale yesinyithi esitshisiweyo luyakhululeka, kwaye amandla okungcangcazela aqhuba ngokukhawuleza kodwa anyamalale kancinci. Xa ukungcangcazela kwangaphandle (njengokusebenza kwezixhobo zeworkshop okanye ukungcangcazela komhlaba) kudluliselwa kwisiseko sesinyithi esitshisiweyo, amaza okungcangcazela aya kubonakaliswa ngokuphindaphindiweyo ngaphakathi kuso, enze isiphumo sokuqaqamba okuqhubekayo. Idatha ibonisa ukuba kuthatha malunga ne-300 ukuya kwi-500 milliseconds ukuba isiseko sesinyithi esitshisiweyo sizinze emva kokuphazamiseka kukungcangcazela, okukhokelela kwimpazamo ye-±3 ukuya kwi-5μm ngexesha lenkqubo yokulinganisa.
Iingenelo zendalo zeziseko zegranite
I-Granite, njengelitye lendalo elenziwe ngeenkqubo zejoloji kwiminyaka engamakhulu ezigidi, inesakhiwo sangaphakathi esixineneyo nesifanayo esineekristale ezidityanisiweyo, esinika iimpawu ezizodwa zokudambisa ukungcangcazela. Xa ukungcangcazela kudluliselwa kwisiseko se-granite, isakhiwo sayo sangaphakathi sinokuguqula ngokukhawuleza amandla okungcangcazela abe ngamandla obushushu, nto leyo efezekisa ukuncitshiswa okusebenzayo. Uphando lubonisa ukuba isiseko se-granite sinokufunxa ngokukhawuleza ukungcangcazela ngaphakathi kwe-50 ukuya kwi-100 milliseconds, kwaye ukusebenza kwayo kokunciphisa ukungcangcazela kuphezulu ngama-60% ukuya kuma-80% kunokwesinyithi esityhidiweyo. Ingalawula impazamo yokulinganisa ngaphakathi kwe-±1μm, inika isiseko esizinzileyo sokulinganisa ngokuchanekileyo okuphezulu.
Uthelekiso lokusebenza kwiimeko zokwenyani zesicelo
Kwindawo yokusebenzela yokuvelisa nge-elektroniki, ukungcangcazela okuphezulu kwezixhobo zoomatshini kunye nezixhobo kuyinto eqhelekileyo. Xa isixhobo sokulinganisa umfanekiso esinemilinganiselo emibini esinesiseko sesinyithi esityhidiweyo silinganisa ubungakanani bomphetho weglasi yesikrini sefowuni ephathwayo, idatha ye-contour iyatshintsha rhoqo ngenxa yokuphazamiseka kokungcangcazela, kwaye kufuneka imilinganiselo ephindaphindiweyo ukuze kufunyanwe idatha esebenzayo. Izixhobo ezinesiseko segranite zinokwenza imifanekiso yexesha langempela nezinzileyo, kwaye zivelise iziphumo ezichanekileyo kumlinganiselo omnye, ziphucula kakhulu ukusebenza kakuhle kokufumanisa.
Kwicandelo lokwenziwa kwe-mold echanekileyo, kukho iimfuno ezingqongqo zokulinganisa umgangatho we-micron we-contours yomphezulu we-mold. Emva kokusetyenziswa ixesha elide, isiseko sesinyithi esityhidiweyo sichaphazeleka kancinci kukungcangcazela kwendalo okuqokelelweyo, kwaye impazamo yokulinganisa iyanda. Isiseko se-granite, kunye nokusebenza kwayo okuzinzileyo kokucinezela ukungcangcazela, sihlala sigcina imeko yokulinganisa echanekileyo, siphepha ngempumelelo ingxaki yokuphinda kusetyenziswe i-mold okubangelwa ziimpazamo.
Ingcebiso yokuphucula: Yiya kwindlela yokulinganisa echanekileyo kakhulu
Ngokuphuculwa okuqhubekayo kweemfuno zokuchaneka kwishishini lokuvelisa, ukuphucula isiseko sesixhobo sokulinganisa umfanekiso esinemilinganiselo emibini ukusuka kwisinyithi esityhidiweyo ukuya kwi-granite kube yindlela ebalulekileyo yokufikelela ekulinganisweni okusebenzayo nokuchanekileyo. Iziseko ze-granite azinakuphucula kuphela ukusebenza kakuhle kokunciphisa ukungcangcazela, zinciphise iimpazamo zokulinganisa, kodwa zandise nobomi benkonzo yezixhobo kwaye zinciphise iindleko zokulungisa. Nokuba yi-elektroniki, imveliso yezixhobo zeemoto, okanye amasimi aphezulu afana neenqwelo moya, ukukhetha isixhobo sokulinganisa umfanekiso esinemilinganiselo emibini esinesiseko se-granite linyathelo lobulumko kumashishini ukuphucula inqanaba lawo lolawulo lomgangatho kunye nokuqinisa ukhuphiswano lwawo kwimarike.
