Kwicandelo lokuvelisa izinto ezikrelekrele, isixhobo sokulinganisa esikrelekrele se-3D, njengesixhobo esiphambili sokufezekisa uvavanyo oluchanekileyo kunye nolawulo lomgangatho, ukuchaneka kwaso kokulinganisa kuchaphazela ngokuthe ngqo umgangatho wokugqibela wemveliso. Isiseko, njengesixhobo esixhasayo esisisiseko sesixhobo sokulinganisa, ukusebenza kwaso okuchasene nokungcangcazela yinto ephambili emisela ukuthembeka kweziphumo zokulinganisa. Kwiminyaka yakutshanje, ukusetyenziswa kwezinto zegranite kwisiseko sezixhobo zokulinganisa ezikrelekrele ze-3D kubangele utshintsho olukhulu kushishino. Idatha ibonisa ukuba xa kuthelekiswa neziseko zesinyithi zemveli, ukumelana nokungcangcazela kweziseko zegranite kunyuke ukuya kuthi ga kwi-83%, nto leyo ezisa inkqubela phambili entsha yobuchwepheshe ekulinganiseni ngokuchanekileyo.
Impembelelo yokungcangcazela kwizixhobo zokulinganisa ezikrelekrele ze-3D
Isixhobo sokulinganisa esikrelekrele se-3D sifumana idatha yezinto enamacala amathathu ngokusebenzisa ubuchwepheshe obufana nokuskena nge-laser kunye nemifanekiso ye-optical. Ii-sensors kunye nezinto ezibonakalayo ezichanekileyo ngaphakathi kuso zinovakalelo olukhulu ekungcangcazeleni. Kwimeko yemveliso yemizi-mveliso, ukungcangcazela okubangelwa kukusebenza kwezixhobo zomatshini, ukuqala nokuma kwezixhobo, kwanokuhamba kwabasebenzi konke oku kunokuphazamisana nokusebenza okuqhelekileyo kwezixhobo zokulinganisa. Nokuba ukungcangcazela okuncinci kunokubangela ukuba umqadi we-laser utshintshe okanye ilensi inyikime, okubangela ukuphambuka kwidatha eqokelelweyo enamacala amathathu kwaye kubangele iimpazamo zokulinganisa. Kwimizi-mveliso eneemfuno eziphezulu kakhulu zokuchaneka ezifana ne-aerospace kunye neetships ze-elektroniki, ezi mpazamo zinokukhokelela kwiimveliso ezingaphantsi komgangatho kwaye zichaphazele nokuzinza kwenkqubo yonke yemveliso.
Imida yokumelana nokungcangcazela kweziseko zesinyithi esityhidiweyo
Isinyithi esitshisiweyo besisoloko sisetyenziswa kakhulu kwisiseko sezixhobo zokulinganisa ezikrelekrele ze-3D ngenxa yexabiso laso eliphantsi kunye nokulula kokusicwangciswa kunye nokubumba. Nangona kunjalo, ulwakhiwo lwangaphakathi lwesinyithi esitshisiweyo lunemingxuma emininzi emincinci kwaye ulungiselelo lwekristale lukhululekile, okwenza kube nzima ukuba lunciphise amandla ngempumelelo ngexesha lenkqubo yokudlulisa ukungcangcazela. Xa ukungcangcazela kwangaphandle kudluliselwa kwisiseko sesinyithi esitshisiweyo, amaza okungcangcazela aya kuphinda abonakale kwaye asasazeke ngaphakathi kwesiseko, enze i-resonance eqhubekayo. Ngokwedatha yovavanyo, kuthatha umyinge we-600 milliseconds ukuba isiseko sesinyithi esitshisiweyo sinciphise ngokupheleleyo ukungcangcazela kwaye sibuyele kwimeko ezinzileyo emva kokuphazamiseka yiyo. Ngexesha lale nkqubo, ukuchaneka kokulinganisa kwesixhobo sokulinganisa kuyachaphazeleka kakhulu, kwaye impazamo yokulinganisa ingaba phezulu njenge ±5μm.
Inzuzo yokulwa nokungcangcazela kweziseko zegranite
I-Granite lilitye lendalo elenziwe ngeenkqubo zejoloji kwiminyaka engamakhulu ezigidi. Iikristale zayo zangaphakathi zezimbiwa zincinci, isakhiwo sixinene kwaye siyafana, kwaye sinokumelana okuhle kakhulu nokungcangcazela. Xa ukungcangcazela kwangaphandle kudluliselwa kwisiseko se-granite, isakhiwo sayo sangaphakathi sinokuguqula ngokukhawuleza amandla okungcangcazela abe ngamandla obushushu, oku kwenza ukuba i-attenuation ibe yimpumelelo. Idatha yovavanyo ibonisa ukuba emva kokuba iphantsi kokuphazamiseka okufanayo kokungcangcazela, isiseko se-granite sinokuphinda sifumane uzinzo malunga ne-100 milliseconds, kwaye ukusebenza kwayo kokuchasana nokungcangcazela kungcono kakhulu kunokwesiseko se-cast iron, kunye nophuculo lwe-83% ekusebenzeni kokuchasana nokungcangcazela xa kuthelekiswa ne-cast iron.
Ukongeza, ipropati ephezulu yokudambisa yegranite iyenza ikwazi ukufunxa ngokufanelekileyo ukungcangcazela kweefrikhwensi ezahlukeneyo. Nokuba kukungcangcazela kwesixhobo somatshini esisebenza rhoqo okanye ukungcangcazela komhlaba okusebenza rhoqo, isiseko segranite sinokunciphisa impembelelo yaso kwisixhobo sokulinganisa. Kwizicelo ezisebenzayo, isixhobo sokulinganisa esikrelekrele se-3D esinesiseko segranite sinokulawula impazamo yokulinganisa ngaphakathi kwe-±0.8μm, nto leyo ephucula kakhulu ukuchaneka nokuthembeka kwedatha yokulinganisa.
Izicelo zoshishino kunye namathemba exesha elizayo
Ukusetyenziswa kweziseko zegranite kwizixhobo zokulinganisa ezikrelekrele ze-3D kubonakalise iingenelo ezibalulekileyo kwiindawo ezininzi zokuvelisa eziphezulu. Ekwenzeni iitships ze-semiconductor, isiseko segranite sinceda isixhobo sokulinganisa amandla ukuba sifumane ukuchongwa ngokuchanekileyo kobukhulu kunye nemilo yeetships, siqinisekisa izinga lokuvelisa iitships. Ekuhlolweni kweenxalenye zeenqwelo-moya, ukusebenza kwayo okuzinzileyo kokulwa nokungcangcazela kuqinisekisa ukulinganiswa ngokuchanekileyo kweenxalenye zomphezulu ezintsonkothileyo, okubonelela ngesiqinisekiso sokusebenza ngokukhuselekileyo kweenqwelo-moya.
Ngenxa yokuphuculwa okuqhubekayo kweemfuno zokuchaneka kwishishini lokuvelisa, amathuba okusetyenziswa kweziseko zegranite kwicandelo lezixhobo zokulinganisa ezikrelekrele ze-3D abanzi. Kwixesha elizayo, ngokuqhubeka nokuqhubela phambili isayensi yezinto kunye nobuchwepheshe bokucubungula, isiseko segranite siya kuphuculwa ngakumbi kuyilo, sinike inkxaso enamandla yokuphucula ukuchaneka kwezixhobo zokulinganisa ezikrelekrele ze-3D kunye nokukhuthaza ishishini lokuvelisa elikrelekrele ukuya kwinqanaba eliphezulu.
