Kev tshuaj xyuas yog ib qho tsis tuaj yeem nkag mus rau hauv kev lag luam niaj hnub, tab sis dab tsi yog cov txheej txheem tshuaj xyuas thiab cov txheej txheem? TTS tau sau cov ntaub ntawv tseem ceeb ntawm FWW kev tshuaj ntsuam xyuas rau koj, kom koj qhov kev tshuaj xyuas cov khoom tuaj yeem ua tau zoo dua!
Cov Khoom Muag Khoom Muag (QC) yog dab tsi
Cov neeg ua haujlwm koom nrog hauv kev tshuaj xyuas kev ua haujlwm raug hu ua QC (cov ntawv luv rau Tus Tswj Xyuas Zoo).
Kev tshuaj xyuas kev ua haujlwm los ntawm QC yog hu ua kev tshuaj xyuas thiab muab faib raws li QC entrusting tog: muaj 3 hom, thawj tog tshuaj ntsuam xyuas, thib ob tog tshuaj xyuas thiab kev soj ntsuam thib peb: thawj tog yog QC teem los ntawm cov chaw tsim khoom; thib peb tog Qhov thib ob tog yog QC xa los ntawm lub tuam txhab neeg siv khoom;
Kev tshuaj xyuas los ntawm ib tus neeg thib peb tau tso siab los ntawm lub chaw soj ntsuam sab nraud rau tus neeg thib ob. FWW muab kev pabcuam thib peb rau kev kuaj xyuas
Kev tshuaj ntsuam xyuas muab los ntawm FWW tau muab faib ua: Kev tshuaj xyuas zaum kawg FQC thiab kev tshuaj xyuas nruab nrab ntawm kev tsim khoom On-line QC raws li cov khoom tiav theem. Cov theem ntxiv yog kev tshuaj xyuas hauv kev tsim khoom, uas yog kev tswj xyuas thaum ntxov rau cov khoom zoo.
Qauv Loj thiab Tso Cai Qib (AQL)
Txoj kev nyab xeeb tshaj plaws los tshuaj xyuas cov khoom yog los tshuaj xyuas 100% ntawm tag nrho cov khoom, tab sis qhov no yuav tsum tau siv sijhawm QC ntau, tshwj xeeb tshaj yog rau cov khoom loj.
Yog li yuav ua li cas peb thiaj li nrhiav tau tus qauv tsim nyog kom sib npaug qhov kev pheej hmoo zoo ntawm cov khoom thiab tus nqi QC. Qhov ntsuas qhov ntsuas no yog "Sample size". Nrog rau cov kev cai ntawm tus naj npawb ntawm cov qauv, qhov teeb meem tom ntej uas QC yuav tsum tau ntsib yog nrhiav qhov tsis xws luag hauv cov txheej txheem ntawm kev kuaj xyuas, muaj pes tsawg qhov tsis xws luag, muaj pes tsawg qhov tsis xws luag tuaj yeem lees txais rau qhov batch no, pes tsawg qhov tsis xws luag, cov khoom xa tuaj no puas yuav tsum tau. raug tsis lees paub? Qhov no yog qib uas tau txais (AQL: Qib Siab Zoo) Qib Siab (Critical, Major, Me)
Cov teeb meem uas pom thaum lub sijhawm tshuaj ntsuam xyuas yuav muab faib ua 3 qib raws li lawv qhov hnyav:
Piv txwv ntawm cov ntsiab lus ntawm qib Critical (Cr.) kev tuag tsis zoo yuav ua rau muaj kev phom sij rau tib neeg lub cev lossis ua txhaum txoj cai lij choj, xws li cov npoo ntse, lub kaum ntse ntse, hluav taws xob to, thiab lwm yam. (feem ntau, cov teeb meem barcode yuav raug txhais ua Cr.) ; Cov khoom muaj ntawv pov thawj, tsis muaj qhov loj (Ma.) qhov tsis xws luag xws li CE Mark, qee qhov haujlwm tseem ceeb lossis cov tsos mob tsis zoo ntawm cov khoom xws li thermal rwb thaiv tsev khob, tsis zoo logo luam ntawv, thiab lwm yam me me (Mi.) cov teeb meem me xws li cov tsos mob me me. ntawm cov khoom xws li cov khoom me ntsis khawb ntawm qhov chaw, me ntsis luam ntawv tsis zoo, thiab lwm yam.
Raws li qhov xwm txheej ib txwm muaj, tus neeg paub txog QC tuaj yeem txiav txim siab qhov kev faib tawm ntawm qhov tsis xws luag thaum kuaj xyuas los ntawm lawv tus kheej raws li cov ntsiab lus saum toj no. Txawm li cas los xij, txhawm rau kom ntseeg tau tias tag nrho cov QCs koom nrog tsis muaj qhov tsis meej meej hauv kev faib cov khoom tsis raug, qee cov neeg siv khoom yuav suav sau Daim Ntawv Teev Npe Tsis Zoo (DCL Defective Classification List), sau tag nrho cov teeb meem ntsig txog cov khoom hauv daim ntawv teev npe tsis raug, thiab qhia. theem defect uas txhua qhov tsis xws luag yuav tsum raug txiav txim. .
Kev siv lub rooj sampling plan
Tom qab qhia cov ntsiab lus ntawm Cov Qauv Loj, AQL thiab qib tsis xws luag, daim ntawv thov tiag tiag xav tau QC los xyuas cov qauv qauv. Tag nrho ntawm 2 daim ntawv siv ua ke, thawj tus daws qhov teeb meem ntawm qhov kos ntau npaum li cas, thiab qhov thib ob daws qhov teeb meem ntawm pes tsawg qhov tsis xws luag tuaj yeem tsis lees paub.
Kauj Ruam 1: Tshawb xyuas thawj daim ntawv, nrhiav cov kab nruab nrab ntawm tag nrho cov khoom ntawm cov khoom lag luam hauv kab "Sampling lot", thiab tom qab ntawd horizontally kos kab hla ntawm "Special Inspection Standard" thiab "General Inspection Standard" los txiav txim. Muaj pes tsawg tus qauv; 2. "Cov qauv tshuaj ntsuam xyuas dav dav" yog siv rau kev kuaj xyuas qhov muag. Muaj ntau qhov kev tshuaj xyuas tag nrho, uas tau muab faib ua peb theem, Qib-I, II, thiab III. Tus lej loj dua, tus lej loj dua; 3. "Kev soj ntsuam tus qauv" yog siv los ua piv txwv ntawm kev ua haujlwm thiab kev tshuaj xyuas qhov loj. Qhov kev soj ntsuam tag nrho yog me me, muab faib ua 4 qib, S-1, S-2, S-3, S-4. Tus lej loj dua, tus lej loj dua.
Tus naj npawb ntawm cov qauv rau FWW yog Qib-II, S-2. Yog tias tag nrho cov khoom lag luam hauv qhov kev tshuaj xyuas no yog 5000pc (ntau 3201-10000), raws li tus qauv default sampling ntawm FWW, tus qauv qauv rau kev soj ntsuam dav dav (zoo li) yog L; tus lej lej rau kev tshuaj xyuas tshwj xeeb (muaj nuj nqi) yog D
Qhov thib ob kauj ruam yog xyuas lub rooj zaum thib ob, qhov twg L sib raug rau tus lej ntawm 200pc; D sib raug rau tus lej 8pc.
Kauj ruam 3 1.Nyob rau hauv lub rooj thib ob, muaj ob kab ntawm Ac Re nyob rau hauv tus nqi ntawm txhua theem kam rau ua. Thaum tag nrho tus lej ntawm qhov tsis xws luag ≤Ac tus nqi, cov khoom tuaj yeem lees txais; thaum tag nrho tus lej ntawm qhov tsis xws luag ≥Re tus nqi, cov khoom raug tsis lees paub. Vim muaj kev sib raug zoo sib xws, tag nrho Re yog 1 ntau dua Ac. 0 yog siv los ua qib kev lees paub tshwj xeeb, uas tsis muaj kev cuam tshuam hauv cov lus no. Nws txhais tau hais tias qhov tsis xws luag yuav tsis muaj nyob. Thaum muaj 1 yam tsis xws luag, cov khoom yuav raug tsis lees paub; 2. Lub neej ntawd AQL ntawm FWW yog Cr. 0; Ma. 2.5; Mi. 4.0, yog tias raws li qhov kev lees paub no: L (200pc) sib raug rau Ma. Ac Re ntawm 10 11, uas yog, thaum tag nrho cov kev puas tsuaj loj tsawg dua los yog sib npaug rau 10, cov khoom tuaj yeem txais tau; thaum tag nrho cov khoom tsis raug yog ≥ 11, cov khoom raug tsis lees paub. Ib yam li ntawd, Ac Re ntawm Mi. yog 14 15.D (8pc) sib raug rau Ma. yog "↑", uas sawv cev rau qib kev lees paub nrog rau cov lus saum toj no, uas yog, 0 1; tus coj Mi. yog “↓”, uas sawv cev rau kev siv rau qib tso cai hauv qab no. Qib txais, uas yog, 1 2Cr. 0, nws txhais tau hais tias kev tuag tsis raug tso cai kom pom
Kos npe
Daim ntawv teev npe (Check List) feem ntau yog siv hauv QC cov haujlwm tshuaj xyuas. Tag nrho cov ntsiab lus uas yuav tsum tau kuaj xyuas cov khoom raug kaw rau hauv daim ntawv kom tsis txhob muaj kev cuam tshuam hauv kev soj ntsuam ntawm QC. Rau cov neeg siv khoom kev koom tes mus ntev, FWW yuav npaj daim ntawv teev npe ua ntej. Daim ntawv txheeb xyuas feem ntau yog siv ua ke nrog Daim Ntawv Teev Npe Tsis Zoo (DCL Defective Classification List).
Cov txheej txheem yooj yim ntawm QC tshuaj xyuas
Kev tshuaj xyuas
KAUJ RUAM 1FWW yuav lees paub cov kev cai tshwj xeeb ntawm kev tshuaj xyuas nrog tus neeg siv khoom thaum ua ntawv thov rau kev tshuaj xyuas, thiab qhia cov qauv loj thiab AQL. thiab xa cov ntaub ntawv mus rau QC cuam tshuam
KAUJ RUAM 2QC yuav hu rau lub Hoobkas tsawg kawg 1 hnub ua ntej hnub tshuaj xyuas kom paub meej tias cov khoom puas tiav raws li qhov xav tau
KAUJ RUAM 3 Nyob rau hnub tshuaj ntsuam xyuas, QC yuav xub nyeem FWW Cov Lus Qhia Kev Ncaj Ncees rau lub Hoobkas
KAUJ RUAM 4 Tom ntej no, QC thawj zaug lees paub qhov ua tiav tag nrho ntawm cov khoom (txawm tias cov khoom tiav 100%; lub ntim yog 80% tiav)
KAUJ RUAM 5 Kos lub thawv raws li tus naj npawb ntawm tag nrho cov thawv
KAUJ RUAM 6 Kos cov ntaub ntawv sab nrauv, cov ntaub ntawv hauv nruab nrab, cov ntaub ntawv khoom
KAUJ RUAM 7 Kev kuaj xyuas cov khoom zoo li qib-II, cov khoom ua haujlwm thiab qhov loj me raws li S-2 qib sampling
KAUJ RUAM 8 Ua kom tiav thiab xam seb puas muaj tag nrho cov teeb meem tsis zoo tshaj tus qauv, thiab lees paub nrog lub Hoobkas
KAUJ RUAM 9 Tom qab kev tshuaj xyuas, npaj FWW daim ntawv tshuaj ntsuam xyuas thiab xa tsab ntawv ceeb toom mus rau cov neeg soj ntsuam
KAUJ RUAM 10 Tom qab cov neeg ua haujlwm tau tshuaj xyuas daim ntawv tshaj tawm, xa email rau cov neeg siv khoom
