Hauv kev tsim khoom, ib kab lus kim tshaj plaws uas koj tuaj yeem hnov yog:
"Tus qauv tsim zoo meej rau ntawm qhov screen-tab sis kuv tsis paub yuav ua li cas nrogniaj hnub CNC machining txheej txheem."
Kuv tau siv ntau xyoo ua haujlwm nrog CAD qauv thiab hauv pem teb khw. Kuv tau pom ntau yam khoom zoo tsim tsis tau thaum lub sijhawm tsim khoom.
Koj tuaj yeem siv sijhawm ntau teev los tsim, ua kom txhua qhov nthuav dav. Koj xa cov duab kos rau cov neeg muag khoom nrog kev ntseeg siab. Tom qab ntawd, koj tuaj yeem tau txais cov lus ceeb toom lossis pom tus kws tsim khoom lag luam co lawv lub taub hau nyob ntsiag to.
Qhov no yog raws nraim qhov twgTsim rau Manufacturability (DFM)los nyob rau hauv.
DFM tsis yog hais txog yuav ua li cas koj kos qhov chaw. txoj kev qhuab qhia rau kev tsim cov khoom lag luam uas ua kom zoo rau tag nrho lub neej voj voog -los ntawm lub tswv yim mus rau qhov xa khoom tiav.
Vim Li Cas Tsim Rau Kev Tsim Khoom (DFM) txiav txim siab 70% ntawm Cov Nqi Khoom Muag?
Hauv kev ua haujlwm ib txwm muaj, cov tsim qauv thiab cov chaw tsim khoom cais tsim thiab tsim khoom. Cov neeg tsim qauv ua tiav cov duab kos thiab "tshem tawm ntawm phab ntsa" mus rau lub Hoobkas. Hauv kev tsim cov khoom lag luam niaj hnub no, txoj hauv kev no yog txoj hauv kev nrawm rau kev ua tsis tiav.
1. Xauv hauv 70% ntawm Tag Nrho Tus Nqi
Cov ntsiab lus tseem ceeb tom qab DFM cov ntsiab lus yogtxo nqi. Cov ntaub ntawv kev lag luam tsis tu ncua qhia tias theem tsim kev txiav txim siab 70-80% ntawm cov khoom lag luam tag nrho.
Thaum pib tsim khoom, kho qhov tsis zoo ntawm tus qauv tsim tuaj yeem raug nqi kaum - lossis txawm tias ib puas- zaus ntau dua li hais txog nws thaum ntxov ntawm theem tsim.
2. Cov txiaj ntsig tseem ceeb ntawm DFM
· Lub Sijhawm Ua Lag Luam sai dua
Txo qis rov qab - thiab - tawm ntawm kev tsim thiab tsim khoom thiab zam kev hloov pauv engineering (ECOs) tshwm sim los ntawm cov yam ntxwv tsis tsim khoom.
· Txhim kho Kev Tswj Xyuas Zoo
Cov qauv yooj yim txo cov txheej txheem sib txawv thiab kev tsim khoom tsis raug.
· Nqis -Kev Tsim Nyog Zoo
Ua tiav cov hom phiaj tseem ceeb ua haujlwm siv qhov tsawg kawg nkaus tsim nyog cov peev txheej tsim khoom.
Tshaj li Cov Txheej Txheem DFM Cov Lus Qhia: Peb Qhov Teeb Meem Tsis Muaj Kev Tsim Nyog
Feem ntau DFM qhia cov kab hluav taws xob thiab qhov tob. Qhov lawv feem ntau nco yog qhov kev paub txog kev tsim khoom implicit zais tom qab cov kev txwv no.
1.Vim li cas ho tsis quav ntsej txog kev ua hauj lwm ua kom nce nqi CNC?
Feem ntau cov cai DFM piav qhia yuav ua li cas tsim cov yam ntxwv -tab sis ob peb piav qhia txog qhov ua tau li castuavntawm lub tshuab.
HauvCNC machining, qhov chaw tsis ntab hauv nruab nrab - huab cua. Yog tias koj tus qauv tsim tsis muaj qhov chaw tiaj tus, zoo li ergonomic tuav, lub Hoobkas yuav xav tau cov cuab yeej kev cai lossis kev pab sab nraud. Qhov no tsav musnon-recurring engineering (NRE)tus nqi tam sim ntawd.
Nyob rau hauv ib tug me me tsav khiav, peb yuav tsum tau tsim ib tug tshwj xeeb fixture. Qhov no yog qhov tsim nyog vim tias qhov tsis muaj qhov siv tau datum nto. Tus nqi teeb tsa ib leeg tshaj tus nqi ntawm cov khoom lawv tus kheej.
Kev pom zoo:
Nco ntsoov khaws tsawg kawg ib txheej txheem datum nto thaum lub sij hawm tsim txheej txheem. Yog tias qhov chaw tiaj tus tsis zoo txaus, xav txog kev ntxiv ib ntus machining tab. Koj tuaj yeem tshem nws tom qab ua tiav. Manufacturers heev tus nqi engineers uas tsim nrog fixturing nyob rau hauv lub siab.
2.Tshaj Tawm Tshaj Tawm -Kev Ua Haujlwm Zoo Tshaj Plaws Ua Haujlwm
Ntau tus tsim qauv tsim cov duab zoo meej hauv CAD. Txawm li cas los xij, lawv feem ntau tsis quav ntsej txog qhov cuam tshuam ntawmkev kho deg zoo li anodizing, kev kho cua sov, lossis hmoov txheej.
Piv txwv li, anodizing yuav tsum tau hooks. Yog tias ib feem ntawm cov tshuaj pleev ib ce tsis muaj cov txheej txheem tsim nyog, cov cim sib txuas tuaj yeem dhau los ua qhov tsis sib haum xeeb.
Hauv qhov project tseem ceeb, peb tsis tau txhais qhov chaw sib txuas. Qhov no ua rau pom cov cim anodizing ntawm tag nrho cov qauv thawj. Raws li qhov tshwm sim, peb tau ntsib ib lub voj voog rov ua haujlwm kim.
Thermal distortion los yog plating thickness tuaj yeem ua rau precision ncej- qhov haum tsis ua haujlwm. Koj yuav tsum xav txog tej yam no.
Kev pom zoo:
Qhov tseeb tsim optimization yuav tsum tau rov qab xav. Thaum txhais qhov kam rau ua, tso cai rau kev kho mob saum npoo av. Yog tias ib feem yuav tsum nyob hauv ± 0.01 hli tom qab anodizing, thov qhia qhov ntev.Koj puas xa mus rau qhov loj me ua ntej plating lossis qhov kawg loj?
3.Kev tshem tawm kev zoo nkauj dua thiab rov qab los ua haujlwm
Ib qho kev ntxhov siab hauv kev tsim khoom yog pom kim 5-axis machining tsuas yog siv los ua kom tsis muaj-kev nyiam ua kom zoo nkauj- feem ntau nyob rau sab hauv, tsis pom qhov chaw.
Hauv kev tsim cov khoom lag luam, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm kev ua kom zoo nkauj ntawm cov khib nyiab kim. Yog tias ib feem yog tag nrho hauv lub tshuab, hloov cov duab 3D nyuaj rau hauv 2.5D cov kauj ruam tuaj yeem txuag nyiaj. Qhov kev hloov no tsis cuam tshuam rau kev ua haujlwm.
Kev pom zoo:
Sib tw txhua qhov kev xav tau. Nug seb puas muaj qhov tshwj xeeb rau kev txo qhov hnyav, tshem tawm, lossis kev xav tau ntawm cov qauv- lossis tsuas yog vim nws "zoo dua." Txhua qhov kev teeb tsa ntxiv ua rau tus nqi nce ntxiv thiab qhia txog qhov muaj feem cuam tshuam txog qhov raug.
Siv DFM los txo CNC Machining Complexity thiab nqi
Yuav kom ua tiav tus nqi -kev tsim khoom zoo, CAD kos duab yuav tsum raug tshuaj xyuas los ntawm amanufacturing txheej txheem foundations.
1. Yuav ua li cas Tolerances Tsav CNC Machining Nqi?
Qhov no yog ib qho ntawm qhov mob loj tshaj plaws rau cov neeg yuav khoom thiab cov kws tsim khoom.Daim pam kam rau uaxws li ± 0.02 hli ntawm txhua qhov ntev ua rau tus nqi nce ntxiv.
Cov cuab yeej siv tshuab tsis yog tshuab luam ntawv. Txhua qhov kev txiav txim - ntawm - qhov kev txo qis hauv kev kam rau siab feem ntau ua rau tus nqi nce ntxiv.
Qhov Zoo Tshaj Plaws:
Siv cov txheej txheem kam rau siab -up. Siv nruj kam rau ua tsuas yog rau cov kev ua haujlwm tseem ceeb, thiab so lawv txhua qhov chaw. Yog tias ± 0.1 hli tau txais, tsis txhob qhia ± 0.05 hli tawm ntawm tus cwj pwm.
2.Tool Physics: Qhov tob tob thiab nyias phab ntsa
Cov cuab yeej txiav muaj qhov ntev - txog - txoj kab uas hla. Qhov sib sib zog nqus ua rau cov cuab yeej sib tham, tsis zoo ntawm qhov chaw tiav, thiab muaj kev pheej hmoo tawg ntxiv. Cov phab ntsa nyias, uas tsawg dua li 0.8 hli rau txhuas lossis txawm tias nyias nyias rau cov yas, tuaj yeem khoov hauv qab txiav quab yuam. Qhov no ua rau nws nyuaj rau tswj qhov ntev.
Cov neeg tsim qauv yuav tsum daws cov teeb meem kev tsim khoom lag luam classic no ntawm theem tsim.
3.Kev zam lub "Ntxhais Khaub Ncaws" Npuas
Cov cuab yeej txiav muaj radii. Kev qhia ntse sab hauv cov ces kaum yuam cov tuam txhab ntxiv cov txheej txheem thib ob xws li EDM, nce nqi nce ntxiv.
Kev pom zoo:
Ntxiv cov fillets sab hauv me ntsis loj dua li tus qauv cuab yeej radii thaum twg los tau. Qhov kev hloov pauv no tuaj yeem txhim kho kev ua haujlwm zoo.
Vim Li Cas Thaum Ntxov DFM Kev Sib Txuas Lus Txom Nyem Rework thiab Quotation Variance?
Cov neeg tsim qauv yws txog cov lus tsis sib xws; manufacturers yws txog cov qauv tsis muaj tseeb. Qhov sib txawv ntawm kev sib txuas lus no yog qhov tseem ceeb ntawm txoj haujlwm qeeb.
1.Enable Early Manufacturing Involvement
Tsis txhob tos kom txog thaum kos duab tiav 100%. Caw cov kws tsim khoom tsim khoom los tshuaj xyuas cov qauv tsim ua ntej. Cov kev hloov pauv ntawm theem no raug nqi me ntsis thiab tuaj yeem txo qhov kev pheej hmoo tom qab.
2.Leverage DFM Reports muaj txiaj ntsig
High -cov neeg muab khoom zoo muab DFM cov ntaub ntawv. Koj yuav tsum saib cov no tsis yog kev zam txim, tab sis yog qhov kev nkag siab zoo rau qhov chaw koj nkim koj cov peev nyiaj thiab qhov twg koj tuaj yeem txhim kho cov qauv.
Tswv yim tswv yim rau kev txiav txim siab Hardware-Makers
Rau kev yuav khoom thiab cov thawj coj engineering, kev nkag siab DFM yog qhov zoo sib tw:
· Txheeb xyuas cov khoom muaj peev xwm technically
Cov neeg muag khoom uas muab cov lus qhia DFM muaj txiaj ntsig zoo dua cov neeg uas tsuas yog hais los ntawm cov duab kos.
· Optimize tag nrho lifecycle tus nqi
Ib feem tsim los rau kev sib dhos yooj yim yuav raug nqi 5% ntxiv rau ib chav. Txawm li cas los xij, nws tuaj yeem txo tus nqi tag nrho los ntawm 20%.
· Shorten txoj kev loj hlob
Txhawb nqa kev sib txuas lus ncaj qha ntawm pab pawg tsim thiab tsim cov engineers.
Xaus: Tus nqi tseeb ntawm DFM
