Thaum txiav cov ntaub ntawv tshwj xeeb, cov hlau txoj hlua khi yuav ntsib teeb meem xws li kev ua haujlwm qeeb, qis txiav qhov raug, txiav qhov chaw txiav, tshwj xeeb qee cov kav hlau me thiab phab ntsa loj lossis cov kav hlau loj uas xav tau txiav ntawm lub kaum ntse ntse, thiab Qee qhov tshwj xeeb (xws li lub tsheb cav sib txuas cov pas nrig), thiab lwm yam, qhov laj thawj tseem ceeb tshaj plaws rau cov teeb meem no yog qhov chaw ua haujlwm muaj qhov tshwj xeeb thiab yooj yim deformed thaum txiav, uas ua rau muaj qhov txiav tsawg. Nrog cov kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis thiab kev tsim ua ib qho nyuaj ntawm cov khoom sib txuam thiab cov qauv vaj tsev, nws tseem yuav tsum tau hloov kho cov cuab yeej ib txwm ua thiab kev ua kom tiav. Nws tuaj yeem pom tau tias tus qauv tsim thiab tsim cov cuab yeej ua ke rau cov tshuab xaws hlau yog qhov tseem ceeb heev rau kev ua haujlwm zoo thiab raug ntawm kev txiav.
Yog li, yam twg yuav tsum tau them sai sai rau thaum tsim qauv fixtures?
1. Qhov loj me: qhov taw tes tseem ceeb tshaj plaws, qhov loj me ntawm lub cuab yeej yuav tsum sib phim nrog qhov loj ntawm qhov workpiece (suav nrog qhov ntev thiab qhov ua siab ntev);
2. Tus qauv: Cov lus teb tseem ceeb yog txoj haujlwm muab tso rau, uas yuav tsum tau tsim kho kom tsim nyog rau ntawm qhov chaw lossis lub puab tsaig, thiab qhov chaw ua haujlwm tuaj yeem tsim kom ruaj khov;
3. Kev ua cov haujlwm: Cov cuab yeej tsim tawm ntawm lub rooj sib tw yuav tsum muaj cov txheej txheem hloov tau yooj yim, cov voj voog ntau lawm yog luv, cov nqi ntau lawm yog li tsawg li, thiab qhov txiav raug siab;
4. Tib neeg-kev taw qhia: tus qauv tsim khoom siv tau yooj yim dua los siv thiab yooj yim rau kev khiav lag luam.
