Ukwenziwa Kokongeza kunye Nokwenziwa Kokutsalwa Kweemveliso: Ingxoxo malunga Nokusetyenziswa KweeMbumba Ezisemva Koomatshini Abachanekileyo
Ukwenziwa kwemizi-mveliso yanamhlanje kubeke phambili iimfuno eziphezulu zokuchaneka, ukusebenza kakuhle kunye nenkululeko yoyilo. Ukongeza kwiiteknoloji zemveli zokwenziwa kwezinto ezingaphantsi (ezifana nokugaya, ukugaya, njl.njl.),ukwenziwa kwezinto ezongezelelweyo (ukuprinta kwe-3D)Itekhnoloji nayo ikhula ngokukhawuleza kwaye iba yindlela ebalulekileyo yokuvelisa izinto ezintsha. Zombini zineengenelo zazo kwaye zisetyenziswa kakhulu kwiinkalo zeemoto, i-aerospace, izixhobo zonyango kunye nokuveliswa koomatshini. Kwezi ndlela zimbini zokwenza, indima yesikhunta ibaluleke kakhulu kwaye inxulumene ngokuthe ngqo nomgangatho wokucubungula kunye nokusebenza kakuhle kwemveliso.
Intshayelelo kwiTekhnoloji yoKwenziwa koLungiso kunye neSicelo seMold
Ukwenziwa kwezinto ezongezelelweyo, okwaziwa ngokuba yi-3D printing, yinkqubo yokwakha iindawo ngokubeka izinto ezisetyenzisiweyo umaleko ngomaleko. Ubuchwepheshe obuqhelekileyo bokuvelisa izinto ezongezelelweyo buquka i-selective laser sintering (SLS), i-selective laser melting (SLM), i-fused deposition modeling (FDM) kunye ne-sterolithography (SLA). Olu hlobo lobuchwephesha lwaziwa ngokukhululeka kwalo koyilo okuphezulu kakhulu. Lunokwenza iindawo ezineemilo ezintsonkothileyo kunye nezakhiwo zangaphakathi okanye zegridi, ngokusetyenziswa okuphezulu kwezinto kunye nokunciphisa kakhulu inkunkuma yezinto. Ukuveliswa kwezinto ezongezelelweyo kufanelekile ngokukodwa kwi-prototyping ekhawulezayo, ukuveliswa kwebhetshi encinci kunye nokwenza ngokwezifiso ngokwezifiso, kwaye kusetyenziswa kakhulu kwi-aerospace, iimoto, izixhobo zonyango kunye nokuveliswa kwe-mold. Iingenelo zalo ziquka ukufinyeza umjikelo wophuhliso, ukukhuthaza uyilo olutsha kunye nokufezekiswa kwezisombululo ezahlukeneyo.
Nangona ukwenziwa kwezinto ezongeziweyo kunokwenza ngokuthe ngqo izakhiwo ezintsonkothileyo, umphezulu weendawo eziprintiweyo uhlala urhabaxa, unemigca yeeleya kunye neziphene ezincinci, kwaye umatshini olandelayo uyafuneka ukuze kuhlangatyezwane neemfuno zobungakanani kunye nomgangatho womphezulu. Ngeli xesha, izinto ezibrasive ezisebenzayo ziba zizixhobo ezibalulekileyo. Izinto ezibrasive ezifanaamavili okugaya, iibhanti zokusantisa, amavili eflap kunye namavili okupolisha zisetyenziswa kakhulu ekususeni iimbumbulu, ukuthambathisa umphezulu kunye nokugqiba iindawo zokwenza izinto ezongezelelweyo ukuqinisekisa ukuba iimveliso zifikelela kumgangatho weshishini ochanekileyo kunye nobuhle. Ingakumbi kwicandelo leenqwelo-moya kunye nezonyango, iimfuno eziphezulu zomgangatho womphezulu kunye nokusebenza kwazo ziye zaqhuba izixhobo zokurhoxa ukuba ziqhubeke nokuphuhlisa izixhobo ezisebenza kakuhle nezinganyangekiyo ukuze zihlangabezane neemfuno ezikhethekileyo zokwenza izinto ezongezelelweyo emva kokucubungula.
Intshayelelo kwitekhnoloji yokuvelisa izinto ezisusayo kunye nokusetyenziswa kwe-abrasive
Ukuveliswa kwezinto ezithatha indawokukususa izinto ezigqithisileyo ngokusika, ukugaya, ukugaya kunye nezinye iindlela zokucubungula umsebenzi ube yimo emiselweyo. Le teknoloji ivuthiwe kwaye ifanelekile kwimveliso yobuninzi, ingakumbi ilungile ekuqinisekiseni ubungakanani obuchanekileyo kunye nomgangatho ogqwesileyo womphezulu. Iinkqubo eziqhelekileyo ziquka ukugaya nge-CNC, ukujika, ukugaya, ukusika ucingo, umatshini wokukhupha umbane (EDM), ukusika nge-laser kunye nokusika ngejethi yamanzi. Ukuvelisa okungaphantsi kudlala indima ephambili kwimveliso yeemoto, i-aerospace, ukwenziwa koomatshini kunye nezixhobo zonyango. Ingacubungula ngokufanelekileyo intsimbi, isinyithi esityhidiweyo, ii-alloys ze-aluminium kunye nezinto ezidityanisiweyo ukuhlangabezana neemfuno ezingqongqo zoshishino ukuze kubekho ukuqina nokusebenza okuncinci.
Ii-abrasives zidlala indima esisiseko nebalulekileyo kwimveliso yokususa izinto, ingakumbi kwinkqubo yokugaya. Iindidi ezahlukeneyo zamavili okugaya (ezifana namavili okugaya e-ceramic, amavili okugaya ahlanganiswe ne-resin) kunye nezixhobo zokupolisha zisetyenziswa kakhulu kwi-rough machining, ukugqiba kunye nokupolisha umphezulu ngokweemfuno zenkqubo ukuqinisekisa ukuba iindawo zifumana ukuchaneka okuphezulu kunye nomgangatho womphezulu okwinqanaba lesipili. Ukusebenza kwe-abrasives kuchaphazela ngokuthe ngqo ukusebenza kakuhle kokucubungula kunye nomgangatho wemveliso, okubangela ukuveliswa kwezinto ezirhabaxa kunye nezakhiwo ukuhlangabezana neemfuno zokucubungula izinto eziqinileyo kunye nejometri ezintsonkothileyo.
Njengebhulorho ebalulekileyo phakathi kwezi zimbini, ii-abrasives zixhasa unxibelelwano olungenamthungo ukusuka kwimveliso yokongeza ukuya kwimveliso yokukhupha. Ngokusetyenziswa okwandayo kwezinto ezidityanisiweyo kunye nezixhobo zokuqina okuphezulu, ukuphuculwa kwetekhnoloji yokukhupha kuye kwaba likhonkco eliphambili ekuqinisekiseni umgangatho wemveliso. Ukuphendula kwiingxaki zoburhabaxa bomphezulu obukhethekileyo kwimveliso yokongeza kunye neemfuno ezichanekileyo zemveliso yokukhupha, uphando kunye nophuhliso lweenkuni luyaqhubeka nokukhula luye kubunzima obuphezulu, ulwakhiwo olungcono kunye nobomi obude, lukhuthaza ubukrelekrele kunye nokusebenza kakuhle kwekhonkco lonke lemveliso.
