Thaum cov engineers feem ntau hnov 'precision prototype machining', lawv tam sim ntawd xav txog micron-theem tolerances thiab flawless nto tiav. Qhov ntawd yog ib feem ntawm nws, paub meej, tab sis yog tias koj tau nyob hauv khw hauv pem teb ntev txaus, koj paub tias qhov kev sib tw tiag tiag tsis yog tsuas yog ntaus tus lej ntawm kev luam ntawv. Nws yog hais txog kev ua ib feem uas ua tau haujlwm hauv lub ntiaj teb tiag tiag, feem ntau nrog cov ntaub ntawv uas tawm tsam koj txhua kauj ruam ntawm txoj kev. Kuv tau pom ntau yam zoo nkauj heev, qhov zoo tshaj plaws zoo tshaj plaws prototypes tsis nyob rau hauv kev sim vim hais tias cov txheej txheem tsom rau qhov tsis ncaj ncees lawm hom precision. Qhov tseeb precision yog nyob rau hauv kev xav, tsis yog txiav.
Cov khoom yog thawj Hurdle
Koj tuaj yeem muaj lub tshuab 5-axis zoo tshaj plaws nyob hauv lub ntiaj teb, tab sis yog tias koj tsis nkag siab cov khoom siv tus kheej, koj tau screwed los ntawm qhov pib. Qhov no yog qhov keeb kwm yav dhau hauv casting, zoo li qhov peb tau tsim ntau xyoo dhau los ntawm Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ua invaluable. Peb tsis yog tshuab blocks ntawm Tshuag; peb feem ntau pib nrog peb tus kheej castings. Yog li thaum tus neeg siv khoom coj tus qauv tsim rau qhov kub-kub aerospace tivthaiv hauv Inconel 718, peb tsis yog xav txog kev pub thiab nrawm. Peb tab tom xav txog qhov kev ntxhov siab uas seem los ntawm cov txheej txheem kev nqis peev casting, yuav ua li cas uas yuav warp thaum peb clamp nws, thiab qhov twg yuav tawm hauv Tshuag ntxiv. Qhov kev paub txog cov ntaub ntawv thawj zaug yog ib daim ntawv ntawm precision feem ntau lub tshuab ntshiab lub khw tsis nco.
Kuv nco qab ib tsab qauv rau lub turbine foob ntu. Cov ntawv luam tawm hu rau qhov vwm-nruj flatness ntawm nyias, dav flange. Thawj qhov kev sim, siv tus qauv vise thiab phau ntawv qhia machining ib ntus los ntawm ib qho thaiv ntawm nickel-raws li alloy, ua rau muaj qhov zoo nkauj, hauv qhov tshwj xeeb. Ntawd yog, kom txog thaum nws so tawm ntawm lub tshuab thiab warped zoo li qos yaj ywm chips. Peb ua tiav machining precision tab sis ua tsis tau raws li tus qauv precision. Ib feem yog tsis muaj txiaj ntsig.
Qhov kho tsis yog lub tshuab fancier. Nws tau rov qab mus rau qhov chaw. Peb tau koom tes nrog peb tus kheej lub plhaub pwm casting pab neeg los tsim ib lub tshuab ua ntej casting nrog ib qho kev txhawb nqa tav hauv qhov chaw tsis tseem ceeb. Cov tav no stabilized ib feem thaum lub sij hawm machining thiab tau hlau-EDM tau tawm raws li cov kauj ruam kawg. Qhov kawg tau tuav nws cov duab. Qhov ntawd yog integrated precision prototype machining-xav txog tag nrho cov lus los ntawm cov hlau molten mus rau cov khoom tiav.
Thaum zoo txaus yog tus yeeb ncuab
Prototypes yog rau kev kawm, yog li muaj kev ntxias kom txiav cov ces kaum. Nws yog ib tug haum-check qauv, lawv hais. Tab sis hauv kuv qhov kev xav, txhua tus qauv yuav tsum tau ua nrog lub hom phiaj ntawm nws ua ib feem ntau lawm. Vim li cas? Vim tias qhov ua tsis tiav koj pom ntawm theem qauv yog cov ntaub ntawv tseem ceeb tshaj plaws uas koj yuav tau txais. Tus qauv sloppy tej zaum yuav haum, zais qhov tsim qhov tsis zoo uas dhau los ua ib lab nyiaj rov qab tom qab.
Peb muaj ib tus neeg siv khoom kho mob ib zaug - ib qho cuab yeej phais. Thawj tus qauv rau lub tsev loj yog machined los ntawm 316 stainless. Nws sib sau ua ke zoo kawg nkaus, thiab lub tshuab ua haujlwm. Tab sis thaum lub sij hawm ua hauj lwm sim, lub anodized aluminium actuating lever tsim me ntsis kev ua si tom qab ob peb puas cycles. Qhov teeb meem tsis yog lub lever machining; nws yog qhov hardness thiab hnav cov yam ntxwv ntawm cov khoom siv piv txwv piv rau cov khoom tsim tawm. Peb tau siv cov khoom lag luam yooj yim rau kev ceev. Qhov zoo txaus qauv yuav luag validated ib tug flawed khoom pairing.
Peb insisted rau machining lub tom ntej no iteration los ntawm qhov tseeb cobalt-chrome alloy teev rau ntau lawm. Nws yog ntuj txiag teb tsaus ntawm cov cuab yeej, raug nqi peb zaug ntau dua, thiab siv sijhawm ntev dua. Tab sis nws tau nthuav tawm qhov teeb meem galling ntawm ob lub khoom nyob rau hauv kev thauj khoom, yuam kev hloov tsim rau lub interface. Qhov ntawd yog qhov tseeb hauv kev txiav txim siab: paub thaum tus qauv fidelity yuav tsum txuas mus rau cov khoom tseeb, tsis yog geometry xwb.
Cov cuab yeej hauv Shed: Ntau tshaj li CNC
Txhua leej txhua tus tham txog CNC machining rau prototypes, thiab nws yog lub workhorse. Tab sis muaj peev xwm tiag tiag los ntawm kev muaj txoj cai thib ob thiab kev txhawb nqa hauv qab ib lub ru tsev. Ntawm QSY, vim peb tab tom los ntawm cov keeb kwm yav dhau los, peb tsis pom machining raws li kev pabcuam cais. Nws yog ib qho cuab yeej hauv lub thawv.
Piv txwv li, ib tug complex impeller qauv tej zaum yuav zoo tshaj plaws raws li ib tug hybrid. Peb yuav tsim cov tub ntxhais geometry raws li kev nqis peev casting hauv duplex stainless hlau, ua tiav cov lus sab hauv uas yuav ua tsis tau lossis kim kim rau tshuab. Tom qab ntawd, peb coj nws mus rau CNC department rau precision machining ntawm lub ntsej muag mounting, bore, thiab hniav tswv yim. Qhov no hybrid mus kom ze tau txais kev ua haujlwm, tus neeg sawv cev qauv rau hauv tus neeg siv khoom txhais tes sai dua thiab feem ntau ntawm tus nqi qis dua li sim hog tawm cov khoom siv. Lub precision yog nyob rau hauv kev xaiv qhov zoo tshaj plaws txheej txheem saw.
Qhov no yog qhov uas koj pom qhov sib txawv ntawm lub khw muag khoom thiab cov chaw muab kev daws teeb meem. Ib lub khw muag khoom sau cov ntawv luam tawm. Peb saib daim ntawv luam thiab nug, Qhov no yog dab tsi? Nws yuav tsum tau tiv thaiv dab tsi? Tom qab ntawd peb tuaj yeem hais, Lub cev tseem ceeb tuaj yeem yog lub plhaub pwm pwm pwm kom txuag lub sijhawm thiab cov khoom siv, thiab peb yuav ua tiav cov kev sib tshuam tseem ceeb ntawm CNC. Qhov kev sib tham, yug los ntawm 30 xyoo ntawm kev ua ob qho tib si cam khwb cia thiab machined qhov chaw, yog ib txheej txheej tseem ceeb ntawm cov kev pab cuam.
Kev sib txuas lus Loop yog qhov tseem ceeb rau kev zam
Nov yog qhov qias neeg me ntsis zais cia: qhov loj tshaj ntawm kev ua yuam kev hauv precision prototype machining tsis yog tshuab cuab yeej raug; nws yog kev sib txuas lus. Ib daim duab yog ib qho qauv ntawm tus qauv ntawm kev xav. Qhov khoob hauv kev nkag siab tau sau nrog cov kev xav, thiab qhov ntawd yog qhov uas cov qauv ua yuam kev.
Peb tam sim no hais rau kev ncaws tawm hu rau txhua tus qauv tsim, txawm tias nws ncua PO los ntawm ib hnub. Peb nug vim li cas txog qee yam nta. Puas yog lub vojvoog tsuas yog rau kev zoo nkauj, lossis rau kev ntxhov siab? Qhov no puas yog lub ntsej muag sealing lossis tsuas yog npog? Cov lus teb hloov pauv li cas peb mus rau nws - toolpath lub tswv yim, kev xaiv txiav, txawm tias qhov kev txiav txim ntawm kev ua haujlwm.
Kuv kawm qhov no nyuaj heev thaum ntxov. Ib tus neeg siv khoom xa ib tus qauv rau lub tsev sensor nrog qhov tob, me me qhov muag tsis pom qhov. Peb machined nws zoo kawg nkaus rau spec. Lawv npau taws heev. Vim li cas? Vim tias lawv tsis tuaj yeem sib txuas lus tias lub qhov yog rau cov kab sib txuas hauv fiber ntau, thiab qhov chaw tiav los ntawm peb qhov kev ua haujlwm drilling tsis yog ntxhib txaus rau cov nplaum kom zoo. Peb yuav tsum rov qab mus thiab manually abrade lub qhov. Kev sib tham tsib feeb tuaj yeem txuag tau ib lub lim tiam. Tam sim no, qhov kev sib tham ntawd yog ib feem ntawm peb cov txheej txheem. Qhov tseeb ntawm qhov kawg yog ncaj qha proportional rau qhov tseeb ntawm qhov kev sib tham thawj zaug.
Saib tom ntej: Precision as a Philosophy
Yog li qhov no tso peb nyob qhov twg? Tom qab peb caug xyoo hauv casting thiab machining, kuv pom precision prototype machining hloov zuj zus. Nws tsawg dua txog kev caum feem kaum ntawm micron ntawm CMM daim ntawv tshaj tawm thiab ntau ntxiv txog kev ncaj ncees. Puas yog tus qauv coj zoo li qhov tsim khoom yuav? Qhov ntawd yog lo lus nug.
Nws txhais tau hais tias qee zaum xaiv qhov kev ua siab ntev me ntsis txhawm rau khaws cov khoom ntiag tug, lossis siv sijhawm ntxiv rau qhov tsis tseem ceeb vim nws qhia txog kev txiav txim siab ntawm kev tsim khoom. Nws yog hais txog kev siv lub peev xwm tag nrho, zoo li qhov peb tau tsim QSY, qhov twg kev paub los ntawm lub cub tawg qhia lub machining vise, thiab cov lus tawm tswv yim los ntawm machining chaw qhia txog kev tsim pwm tsim.
Lub hom phiaj kawg tsis yog ib qho ci ntsa iab hauv ib lub thawv xwb. Nws yog ib daim ntawv pov thawj. Tus qauv ua tiav, ua tiav nrog cov ntsiab lus dav dav ntawm qhov tseeb, tsis yog ua pov thawj tsim ua haujlwm xwb. Nws de-risks tag nrho txoj kev mus rau ntau lawm. Nws qhia koj tias tus nqi tiag tiag yuav nyob qhov twg, qhov twg cov khoom sib tw dag, thiab yuav ua li cas tus tsim yuav tsum khoov kom tau raws li kev tsim khoom tiag. Qhov ntawd yog tus nqi tiag. Thiab kev ua tiav uas yuav tsum muaj ntau tshaj li lub khw muag khoom zoo xwb; nws xav tau tus khub uas xav txog tag nrho lub neej voj voog ntawm ib feem, los ntawm cov khoom siv raw mus rau qhov kawg siv. Qhov ntawd yog hom precision uas qhov tseem ceeb.
