Hauv lub ntiaj teb ntawm kev tsim khoom raug, txhua qhov kev ntsuas xav tau "qhov xoom" - lub dav hlau txhim khu kev qha, tiaj tiaj uas txhua qhov ntev lwm yam tau los ntawm. Tau ntau tshaj ib nrab xyoo pua, lub phaj granite tau ua haujlwm ua qhov kev siv tseem ceeb no. Txawm li cas los xij, thaum nws los txog rau kev teeb tsa chav tshuaj xyuas lossis lub khw tshuab, ib qho ntawm cov lus nug uas peb ntsib ntau tshaj plaws tsis yog txog qhov loj ntawm lub phaj, tab sis yog Qib.
Kev xaiv qib zoo yog qhov kev sib npaug ntawm qhov tseeb uas koj cov haujlwm xav tau thiab qhov tseeb ntawm ib puag ncig ntawm koj qhov chaw ua haujlwm. Kev xaiv qib qis dhau tuaj yeem ua rau koj txoj kev tswj hwm zoo tsis zoo, thaum kev xaiv qib siab dhau lawm tuaj yeem ua rau cov nqi nce siab thiab kev nyuaj siab rau kev saib xyuas. Yuav kom txiav txim siab tau zoo, nws yog ib qho tseem ceeb kom nkag siab txog qhov tseeb ntawm cov qib no thiab lawv ua haujlwm li cas hauv lub ntiaj teb tiag.
Kev Txheeb Xyuas Qhov Tseeb: Nkag Siab Txog Kev Ua Siab Ntev
Cov qib phaj nto tsis yog cov ntawv lo uas tsis raws cai; lawv raug txhais nruj me ntsis los ntawm cov qauv thoob ntiaj teb (xws li ASME B89.3.7 lossis ISO 8512-2). Cov qauv no hais txog "Qhov Yuam Kev Siab Tshaj Plaws" rau qhov tiaj tiaj thoob plaws tag nrho qhov chaw. Thaum peb tham txog qhov tiaj tiaj hauv cov ntsiab lus no, peb tab tom hais txog qhov deb ntawm ob lub dav hlau sib luag uas npog tag nrho cov ncov thiab hav ntawm qhov chaw pob zeb.
Feem ntau, kev lag luam faib cov phaj ua peb qib tseem ceeb:
-
Qib AA (Qib Kuaj Mob): Tus qauv siab tshaj plaws, feem ntau yog rau cov chaw kuaj mob ntsuas kub.
-
Qib A (Qib Tshuaj Xyuas): Lub luag haujlwm ua haujlwm ntawm cov chaw tswj xyuas zoo, muab qib siab ntawm kev raug rau kev tshuaj xyuas dav dav.
-
Qib B (Qib Chav Siv Khoom): Tsim los rau hauv pem teb ua haujlwm, qhov twg cov qauv pib thiab kev kuaj xyuas tsis zoo tshwm sim.
Qhov sib txawv ntawm qhov tiaj tiaj ntawm cov qib no yog ntsuas hauv micrometers (microns). Piv txwv li, ib lub phaj me me ntawm Laboratory Grade AA yuav muaj qhov kam rau siab ntawm 2.5 microns, thaum lub phaj Toolroom Qib B ntawm tib qhov loj me yuav tso cai rau 10 microns. Txawm hais tias cov lej no zoo li me me, lawv dhau los ua qhov tseem ceeb thaum koj tab tom teeb tsa cov blocks gage lossis siv cov ntsuas hluav taws xob siab.
Qib AA: Tus Qauv Hauv Chav Kuaj Mob
Yog tias koj lub chaw ua haujlwm hauv kev tsim khoom siv dav hlau, kev tsim khoom siv kho mob, lossis kev sib dhos semiconductor, Qib AA yuav yog qhov koj xav tau. Cov phaj no yog tsim los rau "master" calibrations. Vim tias qhov kev kam rau siab nruj heev, Cov phaj Qib AA yog qhov rhiab heev rau lawv qhov chaw ib puag ncig.
Ib lub phaj Qib AA tsuas yog qhov tseeb raws li chav uas nws nyob hauv. Hauv chav kuaj ntsuas, qhov kub feem ntau yog tuav nruj me ntsis ntawm 20 ℃ (68 ℉). Yog tias koj yuav tsum tso ib qhoPhaj qib AANyob rau hauv pem teb khw muag khoom uas muaj cua nkag ze ntawm lub qhov rooj qhib, qhov kub thiab txias - qhov sib txawv ntawm qhov kub thiab txias ntawm sab saum toj thiab hauv qab ntawm lub pob zeb - yuav ua rau lub phaj khoov txaus kom txav nws tawm ntawm Qib AA cov lus qhia hauv ob peb feeb. Yog li ntawd, koj tsuas yog yuav tsum xaiv Qib AA yog tias koj muaj ib puag ncig tswj tau los tiv thaiv koj cov peev txheej.
Qib A: Tus Neeg Ua Haujlwm Hauv Chav Tshuaj Xyuas
Rau feem ntau ntawm cov khw muag tshuab precision, Qib A yog qhov kev xaiv zoo tshaj plaws. Nws muab qhov tseeb tsim nyog rau kev txheeb xyuas cov khoom tsim tawm ntawm CNC tshuab yam tsis muaj "finicky" zoo li pob zeb Qib Laboratory. Qib A phaj yog qhov zoo tshaj plaws rau kev siv nrog cov ntsuas qhov siab, cov kab sine, thiab cov tshuab ntsuas sib koom ua ke (CMMs) hauv thaj chaw tshuaj xyuas tshwj xeeb uas, txawm hais tias tej zaum tsis yog "chav huv," khaws cia rau qhov kub thiab txias ruaj khov.
Qib A muaj qhov "zoo tshaj plaws" hauv ROI. Nws muab qhov tseeb txaus kom ua tau raws li feem ntau ntawm cov kev cai ISO 9001 thaum tseem ruaj khov txaus rau ntau tus kws kho tshuab siv txhua hnub.
Qib B: Rugged Accuracy rau Toolroom
Cov phaj qib B yog cov phab ej uas tsis muaj leej twg paub ntawm lub chaw tsim khoom. Cov phaj no yog tsim los siv rau qhov chaw ua haujlwm tiag tiag. Lawv tuab dua thiab ruaj khov dua, tsim los rau kev tuav qhov hnyav ntawm cov khoom nyoos lossis cov khoom siv hnyav.
Txawm hais tias koj yuav tsis siv daim phaj Qib B los kho koj cov blocks master gage, nws txaus rau kev kuaj xyuas qhov layout ntawm ib feem lossis txheeb xyuas qhov teeb tsa ua ntej kev ua haujlwm ntev. Qhov zoo tshaj plaws ntawm Qib B yog nws lub zog; nws muab qhov chaw ruaj khov thiab raug dua li lub rooj ua haujlwm hlau txheem, tab sis nws tsis xav tau kev kho mob "dawb hnab looj tes" ntawm qhov chaw AA.
Cov Yam Tseem Ceeb Yuav Tsum Xav Txog Thaum Xaiv
Thaum txiav txim siab seb yuav yuav qib twg, nug koj tus kheej peb lo lus nug no:
-
Kuv qhov kev kam rau siab tshaj plaws yog dab tsi? Ib txoj cai yooj yim yog 10:1 piv. Koj cov cuab yeej ntsuas (xws li lub phaj nto) yuav tsum raug kaum npaug ntau dua li qhov koj ntsuas. Yog tias koj qhov kev kam rau siab yog ± 0.01 hli, koj qhov kev teeb tsa phaj nto yuav tsum raug txog 0.001 hli.
-
Lub phaj yuav nyob qhov twg? Raws li tau hais lawm, ib puag ncig yog tus yeeb ncuab loj tshaj plaws ntawm qhov tseeb. Cov phaj zoo xav tau qhov kub thiab txias ruaj khov. Yog tias koj chav tshuaj xyuas raug tshav ntuj ntaus lub phaj lossis cov cua txias cua tshuab ncaj qha rau nws, lub phaj Qib AA yuav tsis nyob tiaj tus.
-
Qhov hnyav ntawm cov khoom yog dab tsi? Cov khoom hnyav dua tuaj yeem ua rau "qhov chaw thauj khoom" thiab deflection. Thaum qib hais txog qhov tiaj tus, cov phaj qib siab dua feem ntau xav tau kev kho kom raug ntau zaus yog tias lawv raug kev thauj khoom hnyav uas tuaj yeem hnav cov chaw tshwj xeeb ntawm lub pob zeb dhau sijhawm.
Xaus Lus: Lub Hauv Paus ntawm Kev Ntseeg Siab
Lub phaj granite nto tsis yog tsuas yog ib daim pob zeb xwb; nws yog lub hauv paus ntawm koj cov neeg siv khoom txoj kev ntseeg siab. Txawm koj xaiv qhov tseeb tshaj plaws ntawm Qib AA, qhov kev ntseeg siab ntau yam ntawm Qib A, lossis qhov siv tau zoo ntawm Qib B, qhov tseem ceeb yog xyuas kom meej tias lub phaj raug calibrated tsis tu ncua thiab tswj hwm kom zoo.
Los ntawm kev nkag siab txog cov yam ntxwv ntawm cov qib no, koj tuaj yeem ua kom koj chav tshuaj xyuas tau npaj txhij los daws cov teeb meem ntawm kev tsim khoom niaj hnub yam tsis tas siv nyiaj ntau dhau rau cov lus qhia tsis tsim nyog.
