Mugihe gito cyo gukora, biragoye kuvuga ikoranabuhanga ryiza kuruta imashini ya CNC.Itanga uruvange rwiza rwibyiza birimo ibicuruzwa byinshi byinjira, byukuri kandi bisubirwamo, guhitamo ibikoresho byinshi, no koroshya imikoreshereze.Mugihe ibikoresho byose byimashini bishobora kugenzurwa numubare, imashini igenzura mudasobwa mubisanzwe bivuga gusya kwinshi no guhinduranya.
Kugirango umenye byinshi byukuntu imashini ya CNC ikoreshwa mugutunganya ibicuruzwa, umusaruro muke hamwe na prototyping, injeniyeri.com yavuganye na Wayken Rapid Manufacturing, serivise yo muri protokole ya Shenzhen ikorera muri Shenzhen yerekeye ibikoresho, ikoranabuhanga, porogaramu n'imikorere y'ibikoresho by'imashini za CNC .
Iyo bigeze kubikoresho, niba biza mumpapuro, isahani cyangwa ububiko, amahirwe urashobora kuyikora.Mu magana y’ibyuma bivangwa na polymers bya pulasitike bishobora gutunganywa, plastike ya aluminium na injeniyeri ikunze gukoreshwa mu gutunganya prototype.Ibice bya plastiki byagenewe kubumbabumbwa mubikorwa byinshi bikunze gutunganywa mugice cya prototype kugirango hirindwe igiciro kinini nigihe cyo kuyobora cyo gukora.
Kugera kubintu byinshi byingenzi nibyingenzi mugihe prototyping.Kuberako ibikoresho bitandukanye bifite ibiciro bitandukanye hamwe nuburyo butandukanye bwubukanishi nubumashini, birashobora kuba byiza guca prototype mubikoresho bihendutse kuruta ibyateganijwe kubicuruzwa byanyuma, cyangwa ibikoresho bitandukanye bishobora gufasha guhuza imbaraga, gukomera cyangwa uburemere bwigice bijyanye nigishushanyo cyacyo.Rimwe na rimwe, ibikoresho bisimburana kuri prototype birashobora kwemerera inzira yo kurangiza cyangwa bigakorwa igihe kirekire kuruta igice cyibyakozwe kugirango byorohereze ibizamini.
Ibinyuranye nabyo birashoboka, hamwe nibikoresho bihendutse byibicuruzwa bisimbuza ibyuma byububiko hamwe nibyuma bikora cyane mugihe iyo prototype ikoreshwa muburyo bworoshye bwo gukoresha nko kugenzura neza cyangwa kubaka mockup.
Nubwo yatunganijwe mu gukora ibyuma, plastiki irashobora gukoreshwa neza hamwe nubumenyi bukwiye.Byombi bya termoplastike hamwe na thermosets birashobora gukoreshwa kandi birahenze cyane ugereranije nigihe gito cyo gutera inshinge kubice bya prototype.
Ugereranije nicyuma, thermoplastique nyinshi nka PE, PP cyangwa PS izashonga cyangwa yaka iyo ikozwe nibiryo n'umuvuduko uhuriweho no gukora ibyuma.Umuvuduko mwinshi wo kugabanura hamwe nigipimo cyo kugaburira cyo hasi kirasanzwe, kandi kugabanya ibikoresho nkibikoresho bya rake birakomeye.Kugenzura ubushyuhe mugukata ni ngombwa, ariko bitandukanye nicyuma gikonjesha ntabwo gisanzwe gitera mugukonjesha.Umwuka ucanye urashobora gukoreshwa mugukuraho chip.
Thermoplastique, cyane cyane ibyiciro byibicuruzwa bitujujwe, ihindagurika kuburyo bworoshye nkuko imbaraga zikata zikoreshwa, bigatuma bigorana kugera kubwukuri buhanitse no gukomeza kwihanganirana cyane cyane kubintu byiza nibisobanuro birambuye.Amatara yimodoka hamwe ninzira biragoye cyane.
Hamwe nuburambe bwimyaka irenga 20 hamwe no gutunganya plastike ya CNC, Wayken kabuhariwe muri prototique optique nka lensike yimodoka, kuyobora urumuri na ecran.Iyo gutunganya plastike isobanutse nka polyakarubone na acrylic, kugera hejuru yubuso burambuye mugihe cyo kuyikora birashobora kugabanya cyangwa gukuraho ibikorwa byo gutunganya nko gusya no gusya.Gutunganya micro-nziza ukoresheje imashini imwe ya diyama (SPDM) irashobora gutanga ubunyangamugayo buri munsi ya 200 nm kandi igateza imbere ubukana buri munsi ya 10 nm.
Mugihe ibikoresho byo gukata karbide bikunze gukoreshwa mubikoresho bikomeye nkibyuma, birashobora kugorana kubona igikoresho cyiza cya geometrie yo guca aluminium mubikoresho bya karbide.Kubera iyo mpamvu, ibyuma byihuta (HSS) ibikoresho byo gukata akenshi bikoreshwa.
Imashini ya aluminium ya CNC nimwe mubintu bisanzwe bihitamo ibikoresho.Ugereranije na plastiki, aluminiyumu yaciwe ku biryo byinshi kandi byihuta, kandi irashobora gukata byumye cyangwa hamwe na coolant.Ni ngombwa kumenya urwego rwa aluminium mugihe washyizeho kugirango ugabanye.Kurugero, amanota 6000 arasanzwe cyane, kandi arimo magnesium na silicon.Aya mavuta atanga akazi keza ugereranije n amanota 7000, kurugero, arimo zinc nkibintu byibanze bivanga, kandi bifite imbaraga nubukomezi.
Ni ngombwa kandi kumenya ubushyuhe bwibikoresho bya aluminium.Iri zina ryerekana uburyo bwo kuvura ubushyuhe cyangwa gukomera, urugero, ko ibikoresho byakozwe kandi bishobora guhindura imikorere mugihe cyo gutunganya no gukoresha amaherezo.
Imashini eshanu CNC ikora ihenze cyane kuruta imashini eshatu, ariko ziragenda zigaragara mubikorwa byinganda kubera ibyiza byinshi byikoranabuhanga.Kurugero, gukata igice gifite ibiranga kumpande zombi birashobora kwihuta cyane hamwe na mashini 5-axis, kubera ko igice gishobora gushyirwaho kuburyo spindle ishobora kugera kumpande zombi mugikorwa kimwe, mugihe hamwe na mashini 3 axis , igice gisaba ibice bibiri cyangwa byinshi.Imashini 5 ya axis irashobora kandi kubyara geometrike igoye hamwe nubuso bwiza burangiza kugirango ikorwe neza kuko inguni yigikoresho irashobora guhuzwa nuburyo bwigice.
Usibye urusyo, imisarani hamwe n’ibigo bihindura, imashini za EDM nibindi bikoresho birashobora kugenzurwa na CNC.Kurugero, CNC urusyo + guhinduranya ibigo birasanzwe, kimwe na wire na sinker EDM.Kubatanga serivise yo gukora, ibikoresho byimashini byoroshye nibikoresho byo gutunganya birashobora kongera imikorere no kugabanya ibiciro byo gukora.Guhinduka ni imwe mu nyungu zingenzi zikigo gikora imashini 5-axis, kandi iyo ihujwe nigiciro kinini cyo kugura imashini, iduka rirashishikarizwa cyane kugirango rikomeze gukora 24/7 niba bishoboka.
Imashini isobanutse yerekana ibikorwa byo gutunganya bitanga kwihanganira muri ± 0.05mm, ikoreshwa cyane mubikorwa byimodoka, ibikoresho byubuvuzi nibice byindege.
Ubusanzwe porogaramu ya Micro-Nziza ni Imashini imwe ya Diamond (SPDM cyangwa SPDT).Inyungu nyamukuru yo gutunganya diyama ni kubice byabigenewe byabugenewe hamwe nibisabwa bikenerwa cyane: gukora neza bitarenze 200 nm kimwe no kunoza uburinganire bwubutaka buri munsi ya 10 nm.Mugukora prototypes optique nka plastike isobanutse cyangwa ibyuma byerekana ibyuma, kurangiza hejuru mubibumbano ni ikintu cyingenzi.Gutunganya diyama nuburyo bumwe bwo kubyara ubuso buhanitse, burangije-hejuru mugihe cyo gutunganya, cyane cyane kuri PMMA, PC na aluminiyumu.Abacuruzi kabuhariwe mu gutunganya ibikoresho bya optique biva muri plastiki ni abahanga cyane, ariko batanga serivisi ishobora kugabanya cyane ibiciro ugereranije nigihe gito cyangwa prototype.
Birumvikana ko imashini ya CNC ikoreshwa cyane munganda zose zikora kugirango zikore ibyuma na plastiki bikoreshwa nyuma nibikoresho.Nyamara, mubikorwa byinshi, ubundi buryo nko kubumba, gutara cyangwa gutera kashe akenshi birihuta kandi bihendutse kuruta gukora, nyuma yikiguzi cyambere cyibibumbano hamwe nibikoresho bigabanywa mubice byinshi.
Imashini ya CNC ninzira yatoranijwe yo gukora prototypes mubyuma na plastiki kubera igihe cyayo cyihuse ugereranije nuburyo bwo gucapa 3D, guta, gushushanya cyangwa guhimba, bisaba kubumba, gupfa, nizindi ntambwe zinyongera.
Ubu buryo bwo 'gusunika-buto' bwo guhindura dosiye ya CAD igizwe nigice gikunze kuvugwa nabashyigikira 3D icapiro nkinyungu zingenzi zo gucapa 3D.Ariko, mubihe byinshi, CNC ikundwa no gucapa 3D.
Birashobora gufata amasaha menshi kugirango urangize buri cyiciro cyubaka cyibice byacapwe 3D, mugihe CNC gutunganya bifata iminota.
Icapiro rya 3D ryubaka ibice mubice, bishobora kuvamo imbaraga za anisotropique mugice, ugereranije nigice cyimashini gikozwe mubice bimwe.
Urwego ruto rwibikoresho biboneka mugucapisha 3D birashobora kugabanya imikorere ya prototype yacapwe, mugihe prototype yakozwe irashobora gukorwa mubintu bimwe nkigice cyanyuma.CNC yakozwe na prototypes irashobora gukoreshwa mugukoresha ibikoresho byanyuma kugirango bihuze igenzura ryimikorere hamwe nubuhanga bwa tekinoroji.
Ibikoresho byacapwe 3D nka bores, umwobo wafashwe, guhuza ibice hamwe no kurangiza bisaba gutunganya inyandiko, mubisanzwe hakoreshejwe imashini.
Mugihe icapiro rya 3D ritanga inyungu nkubuhanga bwo gukora, ibikoresho byimashini za CNC byubu bitanga byinshi mubyiza bimwe nta nkomyi.
Imashini yihuta ya CNC irashobora gukoreshwa ubudahwema, amasaha 24 kumunsi.Ibi bituma CNC itunganya ubukungu kubikorwa bigufi byibicuruzwa bisaba ibikorwa byinshi.
Kugirango umenye byinshi kubyerekeranye na CNC itunganya prototypes nibikorwa bito bigufi, nyamuneka hamagara Wayken cyangwa usabe amagambo abinyujije kurubuga rwabo.
