Yuav Ua Li Cas Kev Tshuaj Xyuas Zoo Thaum CNC Machining Txheej Txheem Ntawm Tsheb?

Ib, Qhov tseem ceeb thiab cov txheej txheem ntawm kev tshuaj xyuas zoo
Kev tswj kom zoo rau automotive CNC machining yuav tsum tau saib plaub qhov tseem ceeb:
Dimensional raug: Qhov no suav nrog qhov ntev ntawm qhov ntev (xws li txoj kab uas hla thiab qhov aperture), lub kaum sab xis, qhov chaw kam rau ua (xws li coaxiality thiab perpendicularity), thiab lwm yam. Tag nrho cov no yuav tsum yog nyob rau hauv qhov kam rau ua ntau yam uas pom ntawm daim duab (piv txwv li, ± 0.01mm).
Geometric kam rau ua xws li roundness, flatness, thiab cylindricity muaj qhov cuam tshuam ncaj qha rau cov khoom zoo sib xws thiab ruaj khov npaum li cas thaum lawv txav mus. Piv txwv li, lub cav crankshaft qhov yuam kev cylindricity yuav tsum tau khaws cia rau 0.005mm lossis qis dua.
Deg zoo: khaws cov oxide txheej txawm, qhov roughness ntawm qhov chaw (Ra nqi), thiab tshem tawm ntawm khawb, burrs, thiab lwm yam flaws. Txhawm rau txo qis kev sib txhuam thiab hnav, qhov roughness ntawm aluminium alloy lub tog raj kheej lub cev yuav tsum tsawg dua Ra0.8 μ m.
Cov khoom zoo xws li hardness, tensile zog, tshuaj pleev ib ce, thiab lwm yam yuav tsum tau raws li cov khoom siv. Piv txwv li, qhov nyuaj ntawm qhov siab - lub zog steel qhov chaw yuav tsum nyob nruab nrab ntawm 58 thiab 62HRC kom paub tseeb tias lawv tsis hnav.
2, Muab tso rau hauv qhov chaw Tag Nrho Cov Txheej Txheem Zoo Tshawb Xyuas Tshuab
1. Kev Tswj Xyuas Zoo rau Cov Khoom Muag (IQC): Ua raws li cov khoom zoo
Txheeb xyuas qhov chaw ntawm cov khoom siv raw rau qhov tsis zoo xws li cov kab nrib pleb, oxidation, roj stains, thiab lwm yam nrog lub iav tsom iav los yog saib nws.
Tshawb xyuas qhov loj me: Siv vernier calipers thiab micrometers, peb random xyuas cov kev ntsuas tseem ceeb xws li phaj thickness thiab bar txoj kab uas hla.
Kev soj ntsuam ntawm cov khoom sib xyaw: ceev nrooj xyuas cov khoom qib nrog lub spectrometer (xws li HITACHI X-MET800) kom nres qhov kev coj ua ntawm "hloov cov khoom tsis zoo raws li qhov zoo." Piv txwv li, txhawm rau txhim kho qhov teeb meem ntawm cov ntaub ntawv oxidized sai sai hauv 7075 aluminium alloy, nws yog ib qho tseem ceeb kom tau txais cov ntaub ntawv los ntawm qhov chaw thiab ua qhov kev sim oxidation.
2. Thawj Tsab Ntawv Tshuaj Ntsuam Xyuas (FAI): 2. Thawj Tsab Ntawv Tshuaj Ntsuam Xyuas (FAI): Lub "touchstone" ua ntej ua ntau ntawm lawv
Txheeb xyuas qhov kev pab cuam: Xyuas kom tseeb tias CNC software, kev xaiv cov cuab yeej, thiab txoj kev clamping tag nrho ua tiav cov kev xav tau ntawm cov txheej txheem.
Kev ntsuas qhov loj me: Siv lub tshuab ntsuas kev sib koom tes (CMM) los xyuas peb qhov - qhov loj me ntawm thawj cov khoom thiab xyuas kom meej tias tag nrho cov kev kam rau siab tseem ceeb, suav nrog qhov chaw ntawm qhov thiab qhov sib txawv hauv cov kauj ruam, ua tiav cov qauv tsim. Piv txwv li, thaum machining lub gearbox vaj tse, CMM tshuaj xyuas ua rau qhov ntev 90% ntau dua thiab txiav tus nqi seem rau 0.8%.
Tshawb xyuas qhov zoo ntawm qhov chaw: Tshawb xyuas cov khawb thiab burrs los ntawm saib ntawm qhov chaw thiab ntsuas nws qhov roughness kom paub tseeb tias tsis muaj.
3. Kev Tshawb Fawb Txheej Txheem (IPQC): Saib xyuas cov txheej txheem machining hauv lub sijhawm
Txhua ob xuab moos, qhov tsis sib xws los ntawm cov kab ntau lawm raug kuaj rau qhov loj thiab qhov chaw siab ntev siv cov cuab yeej xws li calipers thiab micrometers.
Saib xyuas qhov tsis muaj: Txheeb xyuas qhov ceev, pub tus nqi, thiab cov cuab yeej hnav cov xwm txheej ntawm cov tshuab hauv lub sijhawm tiag tiag kom tsis txhob muaj teeb meem zoo tshwm sim los ntawm parameter drift. Piv txwv li, thaum machining ib tug turbocharger hniav, qhov nto roughness nyob twj ywm nyob rau hauv Ra0.4 μ m los ntawm kev saib xyuas ntawm qhov chaw txiav.
Cov lus teb ceev rau cov teeb meem: Yog tias muaj qee yam tsis raug, nres lub tshuab tam sim ntawd, txheeb xyuas qhov tsis raug (xws li hnav- tawm cov cuab yeej lossis cov khoom siv xoob), thiab hloov cov txheej txheem kev teeb tsa.
4. Kev soj ntsuam zaum kawg (FQC): Cov kauj ruam kawg ua ntej cov khoom kawg tawm hauv lub tsev rau khoom
Noj cov qauv ntawm tag nrho cov khoom: Siv cov cuab yeej xws li cylindricity meters thiab projectors los nrhiav cov duab thiab txoj hauj lwm kam rau ua ntawm cov txheej txheem nyuaj uas ua tau raws li AQL cov qauv.
Tshawb xyuas qhov zoo: Muaj 100% phau ntawv txheeb xyuas ntawm qhov chaw rau "peb puas tsuaj" (kev puas tsuaj, kev sib tsoo, dai), thiab kev ua haujlwm puas tsuaj yog zam los ntawm kev siv lub tshuab nqus tsev xa khoom thiab ntim khoom txheem.
Kev sim ua haujlwm: Txhawm rau kom paub tseeb tias cov ntsaws ruaj ruaj thiab kis tau tus mob yog txhim khu kev qha nyob rau hauv tiag tiag - ntiaj teb teeb tsa, sim lawv airtightness thiab torque.
3, Cov xwm txheej uas siab -cov cuab yeej kuaj pom tseeb tuaj yeem siv
Coordinate Measuring Machine (CMM): Zoo rau kev tshuaj xyuas peb - qhov ntev ntawm cov khoom nkhaus, suav nrog lub cav lub tog raj kheej taub hau, nrog qhov tseeb ntawm 0.5 μ m+0.5 μ m / m.
Ib qho cuab yeej ntsuas duab yog siv los ntsuas ob - qhov loj me, xws li qhov profile ntawm tus hniav iav. Nws siv optical magnification technology ua qhov no yam tsis tau kov.
Laser scanner: sai sai scans saum npoo ntawm cov npog loj, zoo li lub cev ntawv hlau, kom pom qhov deformation.
Kev kuaj ultrasonic yog ib txoj hauv kev los nrhiav qhov tsis zoo xws li cov kab nrib pleb sab hauv thiab cov pores hauv cov ntaub ntawv. Nws yog ib txoj hauv kev zoo los sim siab - cov khoom steel tsis muaj kev puas tsuaj rau lawv.
Kev ntsuas cov cuab yeej rau hardness thiab hnav tsis kam: Txheeb xyuas seb cov khoom siv hardness puas phim cov qauv tsim thiab kwv yees ntev npaum li cas cov khoom yuav kav ntev npaum li cas ua ntej lawv hnav.
4, Kev txawj ntse thiab digitization txhim kho kev soj ntsuam zoo
Kev tshawb nrhiav hauv online: ib qho system uas siv cov cuab yeej siv tshuab sojntsuam thiab tshuab lub zeem muag thev naus laus zis los tswj "kev ntsuas kev ntsuas nyiaj" hauv lub voj kaw. Tom qab lub tuam txhab pwm precision pib siv lub Renishaw sojntsuam system, qhov tseeb ntawm cov pwm ntxig ua tiav los ntawm 60%.
Cov ntaub ntawv loj tsom xam platform: SPC (Kev Tswj Xyuas Txheej Txheem Txheej Txheem) tso cai rau koj nkag siab cov ntaub ntawv tshawb pom hauv lub sijhawm tiag tiag, ua cov kab kos tswj kom saib xyuas cov txheej txheem kev ruaj ntseg, thiab ceeb toom koj txog cov teeb meem tshwm sim thaum ntxov.
AI- pab nrhiav kom tau: Kev kawm tob tob algorithms cia li pom qhov tsis xws luag xws li khawb thiab burrs thiab muab txoj hauv kev los kho lawv. Qhov no ua rau kev tshawb pom ntau dua 10 npaug ntau dua.
5, System for Management Standardized Operating Procedure (SOP) rau Kev Tshuaj Xyuas Zoo: Ua kom paub meej tias yuav siv cov cuab yeej li cas, ntsuas cov khoom li cas, thiab kev txiav txim siab li cas los ntawm kev sau cov txheej txheem kev ua haujlwm zoo.
Kev cob qhia thiab kev ntsuam xyuas cov neeg ua haujlwm: Cov neeg ua haujlwm soj ntsuam zoo yuav tsum tau cob qhia tsis tu ncua txog kev siv cov cuab yeej tshiab thiab yuav ua li cas thiaj nrhiav tau qhov tsis xws luag. Lawv yuav tsum tau ua lawv txoj haujlwm tom qab dhau qhov kev xeem.
Zoo traceability system: Kom tau txais tag nrho lub neej zoo traceability, khaws cov ntaub ntawv tshuaj xyuas, tus neeg teb xov tooj, thiab cov ntaub ntawv khoom siv rau txhua qhov.
Kev txhim kho txuas ntxiv: Saib cov ntaub ntawv zoo tsis tu ncua, nrhiav cov laj thawj tseem ceeb ntawm kev ua yuam kev (xws li kev hloov pauv ntawm qhov kub thiab txias ntawm cov cuab yeej siv), thiab ua cov txheej txheem tsis zoo thiab cov phiaj xwm kev sim zoo dua.
