Dab tsi yog qhov ua haujlwm uas phim cov khoom me me batch?
Workpieces yog ib qho tseem ceeb heev rau cov neeg tsim khoom ntawm cov tshuab thiab cov khoom tsim khoom. Tsis tsuas yog nws hais txog kev ua haujlwm thiab kev ua tau zoo tag nrho, tab sis nws kuj muaj ntau yam ua rau tus nqi.
Thaum koj tsim qhov chaw rau cov khoom ntim qis xws li FA cov khoom, koj puas xav txog cov txheej txheem tsim khoom thaum tsim?
Rau cov khoom lag luam loj, txawm tias tus nqi ntawm ib qho khoom raug txo qis, cov nqi pib xws li cov nqi pwm yog loj heev. Ntawm qhov tod tes, cov khoom siv FA yog tsim nyob rau hauv cov khoom me me, yog li nws yog ib qho tsim nyog los xaiv ib txoj kev tsim khoom nrog tus nqi qis.
Cov txheej txheem tsim khoom tsim nyog rau kev tsim khoom me me suav nrog, piv txwv li, machining sawv cev los ntawm machining, sheet hlau ua xws li laser txiav, vuam, thiab lwm yam.

Tus khub muaj zog hauv kev tsim cov khoom siv tshuab! Tshuab dhos
Txawm hais tias nws tsuas yog hu ua machining, muaj ntau txoj hauv kev. Machining yog qhov tseem ceeb ntawm kev tshem tawm cov khoom tsis xav tau los ntawm cov khoom siv hauv paus kom ua tiav cov duab xav tau. Qhov kev ua no tseem hu ua kev tshem tawm. Lub ntsiab machining txoj kev yog raws li nram no.
Milling (zeeg)
Nws yog ib qho txheej txheem ntawm kev tshem tawm qhov tsis tsim nyog los ntawm kev kho cov khoom siv thiab txiav nws nrog cov cuab yeej tig. Kuj hu ua machining, nws tuaj yeem hais tias yog ib qho ntawm cov protagonists ntawm machining.
Cov cuab yeej hu ua qhov kawg zeb, thiab cov duab sib txawv thiab qhov ntau thiab tsawg raug xaiv thiab siv raws li daim ntawv thov. Nws yog ntau yam machining txoj kev xws li drilling, txiav nto thiab machining grooves.

Ua ntej, cia peb piav qhia txog cov txheej txheem milling, uas kuj yog tus thawj coj hauv machining.
Txoj kev ua no yog tsim rau kev ua phaj thiab thaiv qhov chaw xws li hauv qab daim hlau thiab plhaub. Nws tuaj yeem hais tias yog txoj kev ua haujlwm tseem ceeb rau kev ua cov khoom xws li FA cov khoom siv.
Cia peb tsim lub tswv yim ntawm qhov chaw machining!
Machining yog ib txheej txheem uas cov khoom raug kho rau ntawm lub rooj ntawm cov khoom siv, thiab tom qab ntawd lub tshuab ua haujlwm siab ceev (kawg zeb) yog nias tawm tsam cov khoom los txiav tawm qhov tsis tsim nyog. Nws yog tsuas yog muaj peev xwm txiav qhov chaw, txiav contours, qhib qhov, slotting, thiab txiav tawm nkhaus nto.
Thiab vim nws yog ib txoj kev ua ntau yam, nws tuaj yeem ua tiav los ntawm kev hloov cov cuab yeej tsim nyog rau txhua txoj kev ua.
Lub hom phiaj dav dav milling tshuab yog lub hom phiaj dav dav milling tshuab uas manually hloov cov cuab yeej thiab ua haujlwm los ntawm cov txheej txheem, thiab lub tshuab ua lej tswj milling uas tuaj yeem ua tus lej tswj (Numerical Control: Numerical Control) ntawm qhov ua haujlwm. Kev tswj tus lej hais txog kev ua haujlwm ntawm kev hloov pauv thiab txav cov ntxaiv thiab txav lub rooj ua haujlwm raws li qhov program.
Tsis tas li ntawd, cov uas nruab nrog ATC (Automatic Tool Changer: Automatic Tool Changer) hu ua machining centers. Txij li ntau yam cuab yeej raug hloov pauv thaum ua tiav, ntau yam kev ua haujlwm tuaj yeem ua tiav ntawm cov khoom siv ib zaug, tsuav yog cov khoom sib dhos thiab qhov kev pab cuam qhib.
Daim duab hauv qab no qhia tau hais tias muaj pes tsawg leeg ntawm lub ntsiab tseem ceeb tam sim no lub hom phiaj machining chaw.

Configuration ntawm machining center (Mori Seiki: NV4000)
Muab cov khoom siv (tsuas yog cov khoom thaiv) rau ntawm lub rooj zaum ua haujlwm, kho nws, txhim kho lub cuab yeej, teeb tsa cov khoom siv hauv paus, thiab tom qab ntawd nkag mus rau cov txheej txheem ua haujlwm. Tom qab ntawd, lub spindle thiab lub rooj yog machined raws li qhov kev pab cuam kom ua tau raws li cov khoom xav tau.
Cov kev pab cuam rau machining hu ua NC cov kev pab cuam. Txoj kev qub zoo li tau muab tso rau ntawm daim kab xev thiab kom daim kab xev nyeem los ntawm lub tshuab. Muaj ob txoj hauv kev los tsim cov kev pab cuam tam sim no.
① Nkag mus rau qhov program ncaj qha rau ntawm tus maub los
② Siv daim ntawv thov PC hu ua CAM los tsim cov ntaub ntawv thiab xa mus rau tus tswj hwm.
Rau cov duab yooj yim, koj tuaj yeem nkag mus rau qhov program hauv txoj kev ntawm ①, thiab rau cov duab nyuaj, koj tuaj yeem siv txoj kev ②.
Cov khoom uas tuaj yeem ua machined
Yog li cas cov khoom uas tuaj yeem ua los ntawm machining yuav zoo li cas? Ntawm no, peb thawj zaug qhia cov qauv piv txwv kom koj tuaj yeem muaj kev xav.
1 ~ 2 axis cov khoom tiav
Qhov yooj yim tshaj plaws los ua yog cov duab uas tuaj yeem ua los ntawm kev xuas nrig ntaus lossis txiav los ntawm ib qho kev taw qhia. Nto machining xws li machining nyob rau hauv ib qho kev taw qhia axial, machining contours ntawm tib qhov siab, thiab grooving yog qhov yooj yim machining.
Raws li pom nyob rau hauv cov piv txwv hauv qab no, lub hauv paus daim hlau uas tsuas yog ntsia hlau qhov los yog drilled qhov ntawm lub dav hlau, los yog blocks nrog ib nrab txiav los yog chamfers, thiab lwm yam. Ntxiv nrog rau qhov thiab qhov txiav, contours thiab grooves tuaj yeem raug machined.
duab
Multi-faceted tiav cov khoom
Qhov no yog cov khoom lag luam uas tau txais los ntawm kev ua ib feem uas pom hauv daim duab saum toj no tsis yog los ntawm ib qho kev taw qhia xwb tab sis los ntawm ntau cov lus qhia. Raws li pom nyob rau hauv daim duab 3, ntxiv rau contour machining, qhov machining, grooving, thiab notch machining los ntawm ib tug kev taw qhia, lub qhov machining kuj yog ua los ntawm lub lateral kev taw qhia.
Daim duab 4 qhia ib qho piv txwv ntawm grooving los ntawm lateral kev taw qhia thiab lub qhov machining los ntawm lwm txoj kev. Nyob rau hauv no machining, cov khoom yog tig, hloov nws orientation, thiab cov duab yog machined nyob rau hauv tag nrho cov lus qhia.
Tom qab machining los ntawm ib qho kev taw qhia, cov khoom yog tig thiab kho dua, tseem hu ua "workpiece changeover".
duab
3-axis machining
3-axis machining yog ib txoj hauv kev uas tuaj yeem txiav cov npoo nkhaus (dawb-daim ntawv, thiab lwm yam) txawm tias thaum ua haujlwm los ntawm ib qho kev taw qhia. Kev ua tiav tiav yog ua tiav los ntawm kev txav mus raws qhov nkhaus ntawm lub pob qhov ntswg kawg zeb nrog ib puag ncig. Tsis yog tsuas yog qhov chaw nrog cov ntaub ntawv dawb raws li qhia hauv daim duab 5 tuaj yeem ua tiav, tab sis kuj tuaj yeem ua tiav qhov nkhaus ntawm cov neeg thiab cov tsiaj raws li qhia hauv daim duab 6 tuaj yeem ua tiav.
Txij li thaum nws yog ib qho tsim nyog yuav tsum tau txav cov ntxaiv hauv 3 qhov ntev raws li qhov nkhaus, tsim ib qho kev pab cuam NC siv daim ntawv thov rau CAM (Computer Aided manufacturing) uas txhawb nqa 3D machining. Txoj kev ua no feem ntau yog siv rau hauv machining ntawm kev txhaj tshuaj molded qhov chaw.
duab
Multi-axis machining cov khoom
Cov khoom uas tsis yog blocky tab sis muaj cov duab zoo tag nrho tuaj yeem raug machined. Los ntawm kev rov kho cov khoom nyob rau hauv tag nrho cov lus qhia thiab siv ib tug 5-axis tshuab, complex duab nrog ntau lub ntsej muag yuav raug tsim. Txoj kev ua no feem ntau yog siv hauv aviation qhov chaw thiab lwm yam.
Cov duab 7 thiab 8 yog cov duab ntawm aerospace feem ntau (schematics). Nws yog tus cwj pwm nyob rau hauv tias muaj ntau txoj kev nyias-walled lug xws li kev sib txuas ntawm cov ntaub ntawv dawb thiab lub qhov ua, protrusions, thiab tag nrho cov duab thinning.
duab
Multi-axis simultaneous machining
Hauv qhov tseeb 5-axis thiab cov cav tov sib xyaw, qee cov duab tuaj yeem tsuas yog tshuab thaum tig cov khoom sib txuas nrog cov cuab yeej txav. Cov duab zoo ib yam yog qhov hu ua rotor hniav raws li pom hauv daim duab 9 (4-axis synchronization) thiab cov duab zoo li lub impeller pom hauv daim duab 10 (5-axis synchronization).
Rau cov duab zoo li no uas tsis tuaj yeem ua los ntawm tsuas yog cov khoom siv kho kom zoo, machining muaj qhov zoo.
duab
Machining tuaj yeem paub qhov ua tiav ntawm yuav luag txhua qhov chaw los ntawm cov duab yooj yim mus rau cov duab nyuaj.
