Prototyping yog ib lub tswv yim zoo los sim koj tus qauv tsim ua ntej tsim cov qauv tsim khoom. 3D Printers thiab CNC Machining yog ob qho tib si siv tau, tab sis txhua tus muaj qhov zoo sib xws thiab cov kev txwv raws li ntau yam kev ua haujlwm. Yog li qhov twg yog qhov kev xaiv zoo dua? Yog tias koj nyob rau hauv qhov teeb meem no, ces kab lus no tsuas yog qhov koj xav tau. Peb yuav nkag mus tob rau hauv ob lub thev naus laus zis thiab sib tham txog ntau yam tseem ceeb los pab koj txiav txim siab seb qhov twg yog qhov zoo tshaj plaws raws li koj qhov project xav tau.
Hauv kab ntawv no peb yuav npog:
3D Printing vs. CNC Machining: Dab tsi yog qhov txawv?
Ua ntej peb dhia mus rau hauv qhov tshwj xeeb, tau txais kev tuav zoo ntawm cov hauv paus yog qhov zoo tshaj plaws. Thawj qhov sib txawv ntawm 3D luam ntawv thiab CNC Machining yog li cas cov khoom kawg ua tiav.
3D luam ntawv yog txheej txheem tsim khoom ntxiv. Qhov no txhais tau hais tias cov khoom kawg yog tsim los ntawm lub tshuab luam ntawv 3D nteg cov txheej txheem ua tiav ntawm cov khoom siv ntawm cov phaj ua haujlwm kom txog thaum cov khoom tiav tiav.
CNC Machining, ntawm qhov tod tes, yog cov txheej txheem tsim tawm. Koj pib nrog ib qho thaiv ntawm cov khoom hu ua ib qho khoob thiab tshuab tawm los yog tshem tawm cov khoom kom sab laug nrog cov khoom kawg.
Yuav ua li cas xaiv qhov zoo tshaj plaws rau koj qhov project xav tau?
Txhua ntawm ob txoj kev tsim khoom muaj qhov zoo sib xws hauv cov xwm txheej tshwj xeeb. Cia peb saib ib leeg ib leeg.
1. Cov khoom siv
Thaum ua haujlwm nrog hlau, CNC machine muaj qhov kom zoo dua. Zuag qhia tag nrho 3D luam ntawv yog tsom rau cov yas. Muaj 3D luam ntawv thev naus laus zis uas tuaj yeem luam tawm hlau, tab sis los ntawm kev xav ntawm prototyping, lawv tuaj yeem kim heev vim tias cov tshuab ua lag luam tuaj yeem raug nqi siab dua $ 100,000.
Lwm qhov tsis zoo nrog 3D luam ntawv hlau yog tias koj cov khoom kawg tsis zoo li lub suab zoo ib yam li qhov ua los ntawm milling tawm ib qho khoom seem. Koj tuaj yeem txhim kho lub zog ntawm 3D-luam hlau ib feem los ntawm kev kho cua sov, uas tuaj yeem ua rau tag nrho cov nqi rau skyrocket. Hais txog superalloys thiab TPU, koj yuav tsum mus nrog 3D luam ntawv.
2. Ntau lawm ntim thiab nqi
Yog tias koj tab tom saib ceev ib-tawm prototypes lossis tsawg ntau lawm (tsawg dua ob tus lej), ces 3D luam ntawv yog pheej yig dua. Rau ntau lawm ntau lawm (siab dua ob tug lej rau ob peb puas), CNC milling yog txoj kev mus.
Cov nqi nce qib ntawm kev tsim khoom ntxiv feem ntau yog qis dua qhov kev tsim tawm rau ib qho kev tsim tawm. Uas tau hais tias, txhua qhov chaw uas tsis tas yuav tsum muaj cov geometry nyuaj tuaj yeem tsim tau tus nqi ntau dua siv CNC machining.
Yog tias koj tab tom saib cov khoom ntim ntau tshaj 500 units, cov txheej txheem tsim cov cuab yeej xws li txhaj tshuaj molding yog qhov kev lag luam ntau dua li kev tsim khoom ntxiv thiab rho tawm.
3. Tsim Complexity
Ob lub thev naus laus zis muaj lawv cov kev txwv, tab sis hauv cov ntsiab lus no, 3D luam ntawv muaj qhov zoo dua. CNC machining tsis tuaj yeem tuav cov geometries nyuaj vim muaj yam xws li cov cuab yeej nkag thiab tshem tawm, cov cuab yeej tuav, thiab cov ntsiab lus mounting. Koj kuj tsis tuaj yeem tshuab square fab vim cov cuab yeej geometry. 3D luam ntawv tso cai rau ntau qhov hloov pauv thaum nws los txog rau cov duab geometry nyuaj.
Lwm qhov yuav tsum tau xav txog yog qhov loj ntawm qhov koj tab tom ua qauv. CNC tshuab tau zoo dua los tuav qhov loj dua. Tsis yog tias tsis muaj 3D tshuab luam ntawv tawm muaj uas tsis loj txaus, tab sis los ntawm qhov kev xav ntawm kev tsim qauv, cov nqi cuam tshuam nrog lub tshuab luam ntawv 3D loj ua rau lawv tsis tuaj yeem ua haujlwm.
4. Dimensional raug
Rau qhov chaw uas yuav tsum tau nruj tolerances, CNC machining yog ib qho kev xaiv meej. CNC milling tuaj yeem ua tiav qib siab ntawm ± 0.025 - 0.125 hli. Nyob rau tib lub sijhawm, 3D tshuab luam ntawv feem ntau muaj nyob ib puag ncig ± 0.3 hli kam rau ua. Tsuas yog rau Direct Metal Laser Sintering (DMLS) cov tshuab luam ntawv uas tuaj yeem ua tiav qhov siab ntev li ± 0.1 hli, cov thev naus laus zis no kim heev rau kev tsim qauv.
5. Nto tiav
CNC machining yog qhov kev xaiv meej yog tias qhov chaw ua tiav zoo tshaj plaws yog qhov tseem ceeb. 3D tshuab luam ntawv tuaj yeem tsim tau qhov zoo nkauj zoo thiab ua tiav, tab sis CNC Machining yog txoj hauv kev mus yog tias koj xav tau qhov zoo tshaj plaws ua tiav rau kev sib raug zoo nrog rau lwm qhov ntau dua.
Phau Ntawv Qhia Yooj Yim los Pab Koj Xaiv
Nov yog cov lus qhia ceev los pab koj txiav txim siab ntawm 3D luam ntawv thiab CNC machining:
- Yog tias koj tab tom saib kev tsim qauv sai, uas cuam tshuam nrog cov duab geometry nyuaj rau tus qauv ib zaug lossis ib qho kev tsim khoom me me, ces 3D luam ntawv yuav yog qhov kev xaiv zoo tshaj plaws.
- Yog tias koj tab tom saib ntau dua kev khiav ntawm ob peb puas qhov chaw nrog cov geometry yooj yim, mus nrog CNC machining.
- Yog tias peb saib kev ua haujlwm nrog cov hlau, tom qab ntawd los ntawm kev pom tus nqi, CNC machining muaj qhov zoo dua. Qhov no tuav txawm tias tsawg. Txawm li cas los xij, cov kev txwv geometry tseem siv tau ntawm no.
- Yog hais tias repeatability, nruj kam rau ua, thiab ib tug zoo meej nto tiav yog heev tseem ceeb, mus nrog CNC machining.
Lo Lus Kawg
3D luam ntawv tseem yog ib qho tshiab thev naus laus zis, thiab nws txoj kev sib ntaus sib tua rau kev lag luam dominance tsuas yog pib xwb. Yog lawm, muaj cov khoom kim heev thiab lub xeev-ntawm-tus-kos duab 3D tshuab luam ntawv uas tau txo qhov sib txawv rau qhov CNC machining muaj peev xwm, tab sis los ntawm qhov kev xav ntawm prototyping, lawv tsis tuaj yeem xav txog ntawm no. Tsis muaj ib qho me me haum rau txhua qhov kev daws teeb meem. Xaiv ib qho ntawm lwm qhov yog nyob ntawm koj qhov project prototyping tus qauv specifications.
