Cov txheej txheem CNC machining yog cov tshuab machining, uas kuj ua raws li cov kev cai txiav ntawm cov tshuab machining thiab feem ntau tib yam li cov txheej txheem machining ntawm cov cuab yeej siv tshuab zoo tib yam.Raws li nws yog lub computer tswj tshuab siv rau kev siv tshuab ua haujlwm hauv kev ua haujlwm tsis siv neeg, thiab yog li muaj kev ua haujlwm siab, siab precision, kev siv tshuab muaj nws tus kheej tshwj xeeb, cov txheej txheem nyuaj, kev ua haujlwm cov kauj ruam yog cov ncauj lus kom ntxaws thiab meej.
Pom tseeb, CNC machining tsuas yog siv cov txheej txheem tsim khoom, nws tsis yog qhov kev xaiv ntawm kev tsim khoom nkaus xwb, qee qhov yuav pom tias nws nyuaj rau kev txiav txim siab txoj hauv kev rau kev tsim khoom.Kab lus no yuav tham txog qhov sib txawv ntawm CNC machining thiab 3D luam ntawv kom thiaj li muaj txiaj ntsig zoo rau koj qhov kev txiav txim siab.
3D luam ntawv (3DP), tseem hu ua additive manufacturing, yog ib lub tshuab uas siv cov qauv ntaub ntawv raws li lub hauv paus rau kev tsim cov khoom los ntawm kev luam ntawv txheej los ntawm txheej siv cov ntaub ntawv bondable xws li hmoov hlau los yog yas.3D luam ntawv kuj tseem tuaj yeem raug cais raws li CNC (computerised numerical control) machining, tab sis 3D luam ntawv, raws li tus neeg sawv cev ntawm cov txheej txheem ntxiv, yog qhov txawv ntawm CNC machining.
1. Txheej txheem txheej txheem
Nyob rau hauv cov nqe lus ntawm kev ua cov qauv, 3D printing yog additive manufacturing.3D luam ntawv suav nrog kev tsim cov txheej txheem los ntawm txheej siv cov tshuab tshwj xeeb xws li lasers lossis rhuab extruders.CNC machining, ntawm qhov tod tes, suav nrog kev siv tag nrho cov khoom, txiav nws thiab ua nws rau hauv cov qauv ntawm cov khoom, uas tuaj yeem txiav txim siab kev tsim tawm hauv kev sib piv (feem ntau cov txheej txheem machining, tshwj tsis yog 3D luam ntawv, yog subtractive manufacturing).
2. Cov khoom sib txawv
1) Cov khoom siv sib txawv
General tes board cov ntaub ntawv tuaj yeem ua tiav siv CNC ua tshuab.
1, yas tes board cov ntaub ntawv yog: ABS, acrylic, PP, PC, POM, nylon, bakelite, thiab lwm yam.
2, kho vajtse tes board cov ntaub ntawv yog: txhuas, txhuas-magnesium alloy, aluminium-zinc alloy, tooj liab, hlau, hlau, thiab lwm yam.
Tam sim no 3D luam ntawv (SLA) cov ntaub ntawv ua haujlwm, tsom rau cov yas ntau dua, ntawm cov khoom siv photosensitive yog feem ntau.Txawm li cas los xij, ntau txoj kev xaiv rau 3D luam ntawv hlau (hlau hmoov) tau raug qhia, tab sis txhawm rau kom 3D luam ntawv hlau, yuav tsum tau siv cov tshuab kim thiab kim.Qhov no tuaj yeem ua rau 3D luam ntawv hlau txwv tsis pub kim, tshwj xeeb tshaj yog rau cov qauv.
2) Cov khoom siv sib txawv
3D luam ntawv, vim nws qhov tshwj xeeb additive manufacturing, muaj cov khoom siv siab heev.
CNC machining, vim qhov yuav tsum tau txiav tag nrho cov khoom thiab yog li cov khoom kawg, yog li CNC machining khoom siv tsis siab li 3D luam ntawv.
3. Qhov sib txawv ntawm kev ua haujlwm
1) Programming
3D luam ntawv: los nrog nws tus kheej tsav tsheb software los txiav txim siab lub sijhawm luam tawm thiab khoom siv.
CNC machining: cov kws tshaj lij thiab cov neeg ua haujlwm yuav tsum tau ua.
2) Machining qhov ntau
3D luam ntawv: tsuav yog tias muaj pallets txaus, ntau tshaj ib feem tuaj yeem luam tawm ib zaug, tsis tas yuav tsum tau ceev faj.
CNC: Tsuas yog ib feem tuaj yeem ua tiav ib zaug.
3) Lub sijhawm ua haujlwm
3D printing: ceev luam ntawv lub sij hawm vim 3D luam ntawv nyob rau hauv ib tug pass.
CNC machining: programming thiab machining siv sijhawm ntev dua 3D luam ntawv.
4. Txheej txheem complexity (kov nto thiab heterogeneous qauv)
3D luam ntawv: qhov chaw uas muaj qhov nkhaus nkhaus thiab cov qauv heterogeneous tuaj yeem ua tiav hauv ib qho dhau los
CNC machining: qhov chaw uas muaj qhov nkhaus nkhaus thiab cov qauv heterogeneous yuav tsum tau programmed thiab dismantled nyob rau hauv ob peb kauj ruam.
5. Qhov sib txawv ntawm qhov raug thiab qhov ua tiav
3D luam ntawv: qhov koj pom yog qhov koj tau txais, kev luam ntawv siab thiab kev ua tiav siab.
CNC machining: muaj tib neeg yuam kev los yog tsis zoo fixtures ua rau machining tsis ua hauj lwm.
6. Cov khoom siv sib txawv
3D luam ntawv: cov khoom molded muaj qhov tsis zoo xws li tsis muaj zog thiab txawm hnav tsis kam.
CNC machining: cov khoom molded muaj qhov zoo xws li lub zog siab thiab hnav tsis kam.
Hauv kev sib piv saum toj no, 3D luam ntawv zoo li muaj qhov zoo dua li CNC machining, tab sis qhov tseeb, vim li cas CNC machining tseem yog cov txheej txheem nyiam rau cov lag luam?Cov laj thawj yog raws li nram no.
1).Economic zoo
Thaum nws los txog rau machining qhov loj thiab hnyav, CNC machining yog pheej yig dua li 3D luam ntawv.Tsis tas li ntawd qee lub tuam txhab tau qhia ntau txoj kev xaiv rau 3D luam ntawv hlau (hlau hmoov), tab sis txhawm rau kom 3D luam ntawv hlau, yuav tsum tau siv cov tshuab kim dua thiab kim heev.Qhov no tuaj yeem ua rau 3D luam ntawv hlau txwv tsis pub kim, tshwj xeeb tshaj yog rau cov qauv.
2).Machining qauv
CNC machining tau tsim nyob rau lub sijhawm ntev thiab twb muaj cov txheej txheem dav dav hauv kev lag luam, suav nrog spindles, cov cuab yeej thiab kev tswj hwm.3D luam ntawv, txawm li cas los xij, tam sim no tsis muaj tus qauv zoo li no.
3).Kev paub
Ntau lub tuam txhab tsis paub meej txog 3D luam ntawv thiab yog nyob rau theem uas lawv tsis paub thiab tsis ntseeg cov txheej txheem, ua rau lawv xaiv CNC machining, uas lawv paub thiab nkag siab, thaum lawv ntsib kev xaiv.
