Ib txoj hauv kev tseem ceeb tshaj plaws rau kev tsim cov hlau thiab yas yog CNC machining. Lub hauv paus ntawm CNC machining yog them rau hauv tsab xov xwm no, nrog rau qee yam ntawm nws cov txiaj ntsig thiab qhov tsis zoo.
Dab tsi yog machining?
Hauv nws txoj kev txhais dav dav, machining yog hais txog cov txheej txheem tsim khoom uas suav nrog kev txiav cov khoom los ntawm cov khoom thaiv. Ua cov khoom raug tshem tawm es tsis yog ntxiv, machining raug xa mus ua "subtractive" txheej txheem tsim khoom. (Txoj kev qhia cov ntaub ntawv raug xa mus rau "kev tsim khoom ntxiv", xws li 3D luam ntawv.)
Hlau, yas, los yog lwm yam khoom siv yuav raug siv thaum lub sij hawm machining txheej txheem, thiab cov tshuab thiab cov cuab yeej yuav nyob rau hauv ntau configurations. Txhawm rau tshem tawm cov khoom siv los ntawm ib qho thaiv, muaj ntau cov txheej txheem, suav nrog drilling, tig, thiab milling (feem ntau hu ua "workpiece").
Txij li thaum xyoo pua 19th, lub ntsiab lus ntawm machining tau siv. Txawm hais tias txoj hauv kev ntawm kev tswj cov cuab yeej txiav tau hloov pauv ntau, nws tseem cuam tshuam rau niaj hnub no.
Dab tsi yogCNC?
Kev tswj cov cuab yeej txav txav yog qhov xav tau rau txhua qhov kev ua haujlwm machining. Tab sis thawj qhov sib txawv ntawm cov niaj hnub, cov thev naus laus zis ntau dua thiab cov txheej txheem machining ib txwm yog txoj kev tswj hwm.
Tag nrho cov riam nyob rau hauv thaum ntxov hnub ntawm machining tau ua rau qee qhov ntawm tes. Siv cov levers lossis lub log, cov kws kho tsheb kho lawv cov mills thiab lathes txhawm rau txhawm rau txiav cov cuab yeej ntse ntawm qhov chaw zoo ntawm lub workpiece. Txoj kev no ntawm machining cov ntaub ntawv nrog qhov tseeb heev los ntawm cov kws txawj ua tshuab yog tseem siv dav niaj hnub no. Txhawm rau ua kom qhov tseeb thiab rov ua dua, koj tuaj yeem siv cov tracers thiab cov qauv.
Txawm li cas los xij, tam sim no muaj lwm txoj hauv kev rau phau ntawv machining, nrog CNC machining-tseem hu ua computer suav lej tswj machining-yog qhov tseem ceeb ntawm lawv. CNC machining yog thawj zaug tsim nyob rau hauv 1940s thiab 1950s.
Hauv CNC machining, cov cuab yeej txiav ntawm lub tshuab yog tswj los ntawm lub computer. Cov lus qhia digital qhia lub tshuab kom paub meej cov kev sib koom ua ke uas ua rau nws ua haujlwm ntawm nws tus kheej es tsis xav kom tus neeg siv tshuab txav cov cuab yeej txiav mus rau ntau qhov chaw ntawm lub workpiece.
CNC machining txheej txheem ua haujlwm li cas?
Lub computerized 3D tsim ntawm cov khoom siv yog tsim los ntawm kev siv computer-aided design (CAD) software ua ntej CNC manufacturing tuaj yeem pib. Cov kws tshaj lij tuaj yeem tsim cov duab sawv cev ntawm cov khoom siv CAD software. 3D duab tuaj yeem hloov kho raws li qhov xav tau ntawm lub vijtsam, thiab qhov kev zov me nyuam qee zaus ua cov simulation los txiav txim siab seb cov khoom tsim tau zoo yuav ua haujlwm li cas hauv kev xyaum.
Thaum CAD tsim tiav lawm, nws tau hloov mus rau "G-code," uas yog cov lus qhia zoo rau lub tshuab CNC, siv computer-aided manufacturing (CAM) software. Lub tshuab nws tus kheej tsis tuaj yeem nkag siab txog peb-dimensional (3D) cov ntaub ntawv tib yam li tib neeg, tab sis nws tuaj yeem nkag siab txog cov lus qhia ncaj nraim uas, thaum ua tiav, yuav ua rau muaj kev loj hlob ntawm 3D duab.
G-code muab cov lus qhia txog thaum twg, qhov twg, thiab ceev npaum li cas lub tshuab motors yuav tsum khiav lag luam. Cov motors no coj lub tshuab kom nws thiaj li tshem tawm cov khoom los ntawm cov khoom kom raug raws li G-code qhia. khoom cuav.
Ib qho tag nrho uas phim tus qauv tsim qauv tsim ntawm CAD program yuav yog qhov tshwm sim yog tias tag nrho cov lus qhia tau ua raws. Cov tivthaiv tuaj yeem raug kho kom zoo dua qub, siv rau nws qhov kev npaj ua haujlwm, lossis rov ua dua tshiab.
Engineer tsim cov khoom siv nrog CAD software G-code yog siv los hloov cov qauv tsim. G-code qhia cov cuab yeej Workpiece cov khoom raug tshem tawm los ntawm lub cuab yeej> Ua haujlwm tiav hauv ib feem.
Qhov zoo ntawm CNC machining
CNC machining yog txheej txheem tsim khoom siv dav siv rau cov qauv thiab cov khoom tsim khoom. Qhov no yog vim muaj ntau yam, suav nrog tus nqi, sijhawm thiab cov khoom siv tshwj xeeb ntawm cov tshuab ua haujlwm.
Pkev txiav txim siab
Vim tias cov tshuab CNC ua raws li cov lus qhia hauv computer, lawv yog qhov tseeb heev-ntau dua li cov neeg txawj ntse tshaj plaws. Feem ntau cov tshuab CNC yog qhov tseeb nyob ib ncig ntawm 0.02mm, uas txhais tau hais tias qhov chaw nyuaj tuaj yeem tsim ua kom nruj heev.
Kev tshem tawm qhov yuam kev yog qhov tseem ceeb tshaj plaws rau cov tuam ntxhab, thiab cov tshuab CNC zoo heev txo qhov ua yuam kev.
Rov ua dua
Ib qho ntawm qhov zoo tshaj plaws txog kev ua cov khoom los ntawm cov lus qhia hauv computer yog tias cov lus qhia no tuaj yeem rov ua dua yam tsis hloov dab tsi. Ntev npaum li cov khoom siv nws tus kheej tau khaws cia zoo, lub tshuab CNC tuaj yeem rov ua cov khoom qub qub.
Nws yog qhov nyuaj dua los ua nrog cov txheej txheem phau ntawv: txawm tias qhov zoo tshaj plaws mechanics tawm tsam los tsim ib lub zoo meej replica txhua zaus.
Scalability
Repeatability kuj muaj txiaj ntsig zoo rau kev ua kom tiav ntau lawm. Vim tias kev ua haujlwm machining tuaj yeem rov ua dua ntau zaus (thiab ntawm ntau lub tshuab yog tias xav tau), cov tuam txhab tuaj yeem tig ib tus qauv sai sai rau hauv ib puas txhiab qhov chaw.
Cov neeg tsim khoom tuaj yeem rov ua dua cov khoom siv tsis tau tas li yog tias cov ntaub ntawv digital nyob ruaj ntseg.
Low nqi zog
Txawm hais tias muaj kev xav txog kev coj ncaj ncees rau txhua qhov kev ua haujlwm tsis siv neeg, siv cov tshuab CNC tuaj yeem txo cov nqi tsim khoom piv rau kev ua haujlwm ib txwm muaj. Thaum G-code raug tsim thiab xa mus rau lub tshuab, nws tuaj yeem tso tseg tsis muaj neeg saib xyuas.
Tau kawg, kev txo qis kev ua haujlwm tsis tas yuav ua rau kev ua haujlwm ntau dhau. Hloov chaw, cov machinists no tuaj yeem xaiv los tsom rau qhov muab qhov zoo tshaj plaws thaum nws tawm ntawm lub tshuab CNC.
Ntau yam
CNC tshuab muaj peev xwm tuav tau ntau yam khoom siv thiab tuaj yeem tsim ntau hom duab. Yog li ntawd, lawv tau siv ntau yam sib txawv, los ntawm cov khoom siv tsheb mus rau cov thawv ntim khoom noj.
Ekev ua siab ntev
Feem ntau cov tshuab CNC tuaj yeem ua haujlwm 24/7 nrog kev saib xyuas yooj yim. Ntev npaum li cov cuab yeej txiav tau khaws cia thiab hloov thaum tsim nyog, CNC tshuab tuaj yeem ua rau muaj kev ua siab ntev, tso cai rau cov khoom ntim ceev ceev.
Disadvantages ntawm CNC machining
Txawm hais tias CNC machining yog siv rau ntau yam kev siv, nws tsis haum rau txhua txoj haujlwm tsim khoom. Nws cov kev txwv muaj xws li los ntawm geometric txwv mus rau tus nqi yam.
Cost
CNC tshuab yog cov cuab yeej siv kim dua li cov tshuab phau ntawv, thiab qhov no tau cuam tshuam txog tus nqi ntawm CNC machined qhov chaw. Txawm li cas los xij, raws li CNC ua ntau dua, qhov sib txawv ntawm tus nqi no yuav me dua.
Tus nqi tseem ceeb kuj tseem nyob ntawm qhov ntim. Rau ib-tawm qhov chaw, 3D luam ntawv yuav yog ib qho pheej yig dua rau CNC machining; rau ntau pua txhiab qhov chaw, cov txheej txheem tsim khoom loj xws li kev txhaj tshuaj molding yuav raug nqi ntau dua.
