Emkhakheni wokulinganisa ngokunemba, ithuluzi lokulinganisa isithombe elinezinhlangothi ezimbili liyithuluzi eliyinhloko lokuthola idatha enembile kakhulu, futhi ikhono lokucindezela ukudlidliza kwesisekelo salo linquma ngqo ukunemba kwemiphumela yokulinganisa. Lapho kubhekene nokuphazamiseka kokudlidliza okungenakugwenywa endaweni eyinkimbinkimbi yezimboni, ukukhethwa kwezinto eziyisisekelo kuba yinto ebalulekile ethinta ukusebenza kwethuluzi lokulinganisa isithombe. Lesi sihloko sizokwenza ukuqhathanisa okujulile phakathi kwe-granite ne-cast iron njengezinto ezimbili eziyisisekelo, sihlaziye umehluko obalulekile ekusebenzeni kahle kwazo kokucindezela ukudlidliza, futhi sinikeze ireferensi yokuthuthukisa yesayensi kubasebenzisi bemboni.
Ithonya lokudlidliza ekunembeni kokulinganisa kwezinsimbi zokulinganisa zesithombe ezinezinhlangothi ezimbili
Ithuluzi lokulinganisa isithombe elinobukhulu obubili libamba ukwakheka kwento evivinywayo ngokuthembela ohlelweni lokuthwebula izithombe olubonakalayo futhi liqaphela ukulinganiswa kosayizi ngokubalwa kwesofthiwe. Phakathi nale nqubo, noma yikuphi ukudlidliza okuncane kuzokwenza ilensi inyakaze futhi into elinganiswayo ishintshe, okuholela ekufiphaleni kwesithombe kanye nokuphambuka kwedatha. Isibonelo, ekulinganisweni kwesikhala sephini lama-chip kagesi, uma isisekelo sehluleka ukucindezela ngempumelelo ukudlidliza, amaphutha okulinganisa angaholela ekwahluleleni kabi ikhwalithi yomkhiqizo futhi athinte izinga lokukhiqiza lomugqa wonke wokukhiqiza.
Izakhiwo zezinto ezibonakalayo zinquma umehluko ekucindezelweni kokudlidliza
Imikhawulo yokusebenza kwezisekelo zensimbi ephonswe
Insimbi ephothiwe iyinto evame ukusetshenziswa njengesisekelo sezinsimbi zokulinganisa zesithombe zendabuko futhi iyathandwa ngenxa yokuqina kwayo okuphezulu kanye nokusebenziseka kalula. Kodwa-ke, isakhiwo sangaphakathi sekristalu sensimbi ephothiwe siyaxega, futhi amandla okudlidliza asebenza ngokushesha kodwa anyamalala kancane. Lapho ukudlidliza kwangaphandle (njengokusebenza kwemishini yokusebenzela noma ukudlidliza komhlabathi) kudluliselwa esisekelweni sensimbi ephothiwe, amagagasi okudlidliza azobonakala ngokuphindaphindiwe ngaphakathi kwawo, akhe umphumela wokuqaqamba okuqhubekayo. Idatha ikhombisa ukuthi kuthatha cishe ama-millisecond angu-300 kuya kwangu-500 ukuze isisekelo sensimbi ephothiwe sizinze ngemva kokuphazamiseka ukudlidliza, okuholela ephutheni lika-±3 kuya ku-5μm ngesikhathi senqubo yokulinganisa.
Izinzuzo zemvelo zezisekelo zegranite
I-Granite, njengetshe lemvelo elakhiwe ngezinqubo ze-geological eminyakeni engamakhulu ezigidi, inesakhiwo sangaphakathi esiminyene nesifanayo esinamakristalu ahlanganiswe kahle, esihlinzeka ngezici ezihlukile zokudambisa ukudlidliza. Lapho ukudlidliza kudluliselwa esisekelweni se-granite, isakhiwo sayo sangaphakathi singaguqula ngokushesha amandla okudlidliza abe amandla okushisa, sifinyelele ekunciphiseni okuphumelelayo. Ucwaningo lubonisa ukuthi isisekelo se-granite singamunca ngokushesha ukudlidliza kungakapheli ama-millisecond angu-50 kuya kwangu-100, futhi ukusebenza kahle kokucindezela ukudlidliza kuphakeme ngo-60% kuya ku-80% kunokwensimbi ephonswe. Ingalawula iphutha lokulinganisa kungakapheli i-±1μm, inikeze isisekelo esiqinile sokulinganisa okunembile kakhulu.
Ukuqhathaniswa kokusebenza ezimweni zangempela zohlelo lokusebenza
Eshabhu lokukhiqiza elekthronikhi, ukudlidliza okuvama kakhulu kwamathuluzi omshini nemishini kuyinto evamile. Lapho ithuluzi lokulinganisa isithombe elinezinhlangothi ezimbili elinesisekelo sensimbi ephonswe lilinganisa usayizi womphetho wengilazi yesikrini sefoni ephathekayo, idatha ye-contour iyashintshashintsha njalo ngenxa yokuphazamiseka kokudlidliza, futhi kudingeka izilinganiso eziphindaphindwayo ukuze kutholakale idatha evumelekile. Imishini enesisekelo se-granite ingakha izithombe zesikhathi sangempela nezizinzile, futhi ikhiphe imiphumela enembile ekulinganisweni okukodwa, ithuthukise kakhulu ukusebenza kahle kokuthola.
Emkhakheni wokukhiqiza isikhunta ngokunemba, kunezidingo eziqinile zokulinganisa izinga le-micron le-contours yobuso besikhunta. Ngemva kokusetshenziswa isikhathi eside, isisekelo sensimbi ecijile sithinteka kancane kancane yi-cumulative environment vibration, futhi iphutha lokulinganisa liyakhula. Isisekelo se-granite, ngokusebenza kwaso okuzinzile kokucindezela ukudlidliza, sihlala sigcina isimo sokulinganisa esinembile kakhulu, sigwema ngempumelelo inkinga yokulungiswa kabusha kwesikhunta okubangelwa amaphutha.
Isiphakamiso sokuthuthukisa: Hambisa ekulinganisweni okunembe kakhulu
Ngokuthuthuka okuqhubekayo kwezidingo zokunemba embonini yokukhiqiza, ukuthuthukisa isisekelo sethuluzi lokulinganisa isithombe esinezinhlangothi ezimbili kusukela ku-cast iron kuya ku-granite sekuyindlela ebalulekile yokufeza ukulinganisa okusebenzayo nokunembile. Izisekelo ze-granite azikwazi nje kuphela ukuthuthukisa ukusebenza kahle kokucindezela ukudlidliza, ukunciphisa amaphutha okulinganisa, kodwa futhi zandise impilo yesevisi yemishini kanye nezindleko zokulungisa eziphansi. Kungakhathaliseki ukuthi yizinto ze-elekthronikhi, ukukhiqizwa kwezingxenye zezimoto, noma amasimu aphezulu njengezindiza, ukukhetha ithuluzi lokulinganisa isithombe elinezinhlangothi ezimbili elinesisekelo se-granite kuyisinyathelo esihlakaniphile samabhizinisi sokuthuthukisa izinga lawo lokulawula ikhwalithi nokuqinisa ukuncintisana kwawo emakethe.
