Thaum ib feem tshiab tsim tsaws rau ntawm koj lub rooj, qhov kev ntxias yog dhia ncaj nraim rau hauv kev tsim kho tuag. Txawm li cas los xij, hla lubDesign for Manufacturing (DFM) tshuaj xyuasyog txoj kev ceev tshaj plaws los tig ib txoj haujlwm tau txais txiaj ntsig mus rau hauv ib qho ntawm cov nqi rov qab tsim dua tshiab. Rau cov thawj coj kev yuav khoom thiab cov kws ua haujlwm ua haujlwm, tus nqi tiag tiag ntawm tus neeg sab saum toj -tier tooling khub tsis yog lawv lub peev xwm los txiav steel xwb- nws yog lawv lub peev xwm los pom qhov ua tsis tiav ua ntej thawj kab noj hniav yog machined. Yog tias koj xav kom muaj kev ruaj ntseg siab - daim ntawv cog lus muaj txiaj ntsig thiab txo koj lub sijhawm ua haujlwm, koj yuav tsum paub txog kev kos duab ntawm kev sib koom tes engineering.
DFM Advantage: Txheeb xyuas "Yuav Tsis Tau" Nta
Ntau tus engineers tsim qhov chaw uas yog qhov zoo tshaj plaws, tab sis kev ua haujlwm tsis yooj yim sua kom stamp zoo. Lub kaum sab xis sab hauv, qhov sib piv tsis txaus, lossis tsis txaus khoov radii yog qhov teeb meem tshwm sim uas ua rau muaj kev ntxhov siab thiab cov cuab yeej ua tsis tiav ntxov. Kev tsom xam DFM nruj qhia cov teeb meem tam sim ntawd. Piv txwv li, los ntawm me ntsis nce lub vojvoog ntawm ib daim ntawv nyuaj, koj tuaj yeem txo cov khoom thinning uas tshwm sim thaum lub sij hawm sib sib zog nqus nqus, uas ua rau kom qhov kev ncaj ncees ntawm cov qauv thiab koj cov khoom tsim tawm.
Tswj cov khoom ntws hauv qhov sib sib zog nqus -Drawn Cheebtsam
Ib qho nyuaj tshaj plaws hauv kev tsim cov hlau yog "caij nplooj ntoos hlav-rov qab" thiab cov khoom tawg hauv qhov sib sib zog nqus- kos duab geometries. Yog tias koj qhov yuav tsum muaj qhov tob tob, qhov ntws ntawm cov hlau yuav tsum tau ua tib zoo tswj los ntawm qhov khoob - tuav quab yuam thiab kos cov hlaws dai. Tus tsim cov cuab yeej siv caij nyoog siv CAE (Computer-Aided Engineering) software los simulate cov hlau txav los ntawm cov chaw tuag. Qhov kev simulation no tsis yog ib qho kev tawm dag zog xwb; nws yog tus nqi -txuag ntsuas. Los ntawm kev kwv yees qhov twg cov khoom yuav nyias tawm los yog wrinkle, tus tsim qauv tuaj yeem ua kom zoo dua qhov kev kos cov hlaws dai, kom ntseeg tau tias qhov kawg ua tau raws li nws qhov ntev ntev yam tsis tas yuav tsum tau kho cov theem ob kim.
Yog vim li cas Standardized Qhov - rau - Ntug Ratios Matter
Nyob rau hauv siab - stamping precision, qhov sib thooj ntawm qhov los yog txiav tawm mus rau ntawm ntug ntawm ib feem yog ib qho tseem ceeb ntawm kev tsim qauv. Yog hais tias ib lub qhov nyob ze rau ntawm lub periphery, cov phab ntsa tuag yuav nyias thiab nquag mus rau chipping nyob rau hauv lub loj loj quab yuam ntawm xovxwm. Thaum lub sij hawm tsim kev tshuaj xyuas, koj tus khub tsim khoom yuav tsum muab cov lus teb rau cov "geometry traps." Tshaj tawm qhov kev hloov me me rau qhov chaw tso tawm -los yog siv tus qauv punched stepped - tuaj yeem tiv thaiv kev puas tsuaj ntawm cov cuab yeej tawg. Cov kev hloov kho me me no yog lub cim ntawm tus khub uas mob siab rau koj lub sijhawm ntev - kev vam meej tshaj li qhov kev sib tw thawj zaug.
Kev sib txuas ntawm qhov sib txawv ntawm tus qauv thiab ntau lawm
Feem ntau, ib feem uas ua haujlwm zoo kawg nkaus hauv 3D- cov qauv luam tawm lossis qis - ntim mos- ib puag ncig cov cuab yeej yuav ua tsis tiav hauv cov khoom siv steel hlau tuag. Cov rog koom nrog hauv kev tsim khoom loj, ua ke nrog siab - lub sij hawm voj voog ceev, tsim thermal thiab mechanical stresses uas prototypes tsis replicate. Los ntawm kev ua qhov kev tshuaj xyuas DFM, koj txheeb xyuas cov ntsiab lus hloov pauv uas koj tus qauv tsim yuav tsum tau ua kom tawv rau kev tsim khoom loj. Qhov txuas ntawm "lub tswv yim" thiab "scale" no yog qhov uas koj tsim tus nqi tshaj plaws rau koj cov neeg siv khoom, vim nws ua kom lawv txoj kev hloov mus rau siab - ntim ntau lawm yog du, kwv yees, thiab tsis muaj cov fwj ntau uas muaj kab mob tsawg dua - npaj cov khw muag khoom.
Tig Technical Feedback rau Cov Neeg Siv Khoom
Thaum koj nthuav qhia DFM daim ntawv qhia meej rau tus neeg siv khoom, koj hloov qhov xwm txheej ntawm kev sib tham. Koj tsis yog "tus neeg muag khoom" nkaus xwb; koj yog tus kws pab tswv yim engineering optimizing lawv cov khoom rau lub lag luam thoob ntiaj teb. Txoj kev sib tham no yog lub cuab yeej muaj zog rau kev yeej cov neeg siv khoom tshiab. Nws qhia tau hais tias koj muaj peev xwm loj hlob tuaj saib lawv cov ntaub ntawv CAD, pom cov txheej txheem tsim, thiab cia siab tias yuav muaj teeb meem ua ntej lawv yuav muaj teeb meem. Hauv kev lag luam thoob ntiaj teb, qhov kev ntseeg siab thiab kev txawj ntse yog cov txiaj ntsig ntawm kev ua tiav, cov txheej txheem DFM pob tshab yog koj txoj hauv kev zoo tshaj plaws los txiav txim siab koj tus kheej los ntawm cov neeg sib tw uas tsuas yog lees txais cov ntaub ntawv thiab tsim los luam tawm yam tsis tau nug lus nug.
Yog tias koj pab neeg tab tom ntsib kev thim rov qab ntawm tus nqi lossis yog tias koj pom koj tus kheej tawm tsam kom yeej qhov kev sib tw tawm tsam tus nqi qis - nqi, qis - khw muag khoom zoo, sim ua nrog koj cov txheej txheem DFM. Muab qhov kev sib tham thawj zaug uas yog ib feem ntawm koj qhov kev pom zoo. Los ntawm kev pab koj cov neeg siv khoom nkag siab txog "vim li cas" tom qab koj cov kev txiav txim siab, koj txhawb txoj kev sib raug zoo los ntawm kev lag luam mus rau kev tawm tswv yim, kom ntseeg tau tias koj raug saib tsis yog cov chaw tsim khoom, tab sis yog tus khub tseem ceeb hauv lawv txoj kev ua tiav.
