Hauv kev tsim cov txheej txheem ntawm cov khoom siv tshuab, vim tias cov khoom yuav tsum tau ua thiab cov xwm txheej ntawm ntau qhov chaw sib txawv, cov txheej txheem tsim khoom kuj txawv. Tib qhov chaw siv cov txheej txheem sib txawv rau kev tsim khoom, nws cov khoom siv tau zoo, kev lag luam kev lag luam tsis zoo ib yam. Nyob rau hauv lub hauv paus ntawm kev ua kom ntseeg tau qhov zoo ntawm cov khoom, cov txheej txheem ntawm kev teeb tsa ib qho kev qhia zoo thiab cov txiaj ntsig kev lag luam, cov txheej txheem tsim nyog thiab ua tau yog hu ua txheej txheem tsim ntawm cov khoom. Yog li dab tsi yog cov txheej txheem kev tsim khoom tshwj xeeb? Cov nram qab no los ntawm peb los qhia koj txog cov txheej txheem ntawm precision qhov chaw ua dab tsi.
1. Cov txheej txheem ntau lawm los ntawm kev tsim cov duab kos rau hauv cov khoom, mus dhau ntawm cov txheej txheem tsim khoom. Feem ntau cov khoom siv raw lossis cov khoom ua tiav rau hauv cov khoom tom qab tag nrho cov txheej txheem hu ua txheej txheem ntau lawm. Cov txheej txheem ntau lawm feem ntau suav nrog:
(1) kev npaj txheej txheem suav nrog kev tshawb fawb kev lag luam, kev kwv yees, kev txheeb xyuas cov khoom tshiab, txheej txheem tsim, kev tshuaj xyuas tus qauv, thiab lwm yam ua ntej cov khoom yuav muab tso rau hauv ntau lawm.
(2) los yog txheej txheem yog hais txog cov txheej txheem ncaj qha hloov qhov loj me, cov duab, kev sib txuas ntawm qhov chaw, nto roughness lossis kev ua tau zoo ntawm cov khoom siv raw khoom semi-tiav, kom lawv dhau los ua cov khoom tiav. Piv txwv li, ua kua, yas rau hauv cov duab, vuam, hmoov sib sau, txiav thiab machining, kev kho cua sov, kev kho deg, sib dhos, thiab lwm yam., tag nrho cov txheej txheem. Cov txheej txheem tsim nyog yuav raug sau rau hauv cov ntaub ntawv kev siv los qhia kev tsim khoom, cov ntaub ntawv no hu ua txheej txheem txheej txheem.
(3) Cov txheej txheem tsim khoom pabcuam yog hais txog cov haujlwm pabcuam tsim khoom tsim nyog los xyuas kom meej qhov kev coj ua ntawm cov txheej txheem tsim khoom.
(4) Kev pabcuam kev tsim khoom yog hais txog lub koom haum ntawm cov khoom siv raw, kev thauj mus los, kev cia khoom, kev cia khoom, kev ntim khoom thiab ntim khoom, kev muag khoom thiab lwm yam txheej txheem.
2. Cov txheej txheem ntawm cov txheej txheem txiav cov txheej txheem yog kev sib xyaw ua ke ntawm ntau cov txheej txheem, txhua tus txheej txheem yog tsim los ntawm chaw nres tsheb, cov kauj ruam ua haujlwm, cov cuab yeej taug kev thiab kev teeb tsa.
