Feem ntau cov vuam fixtures tshwj xeeb yog tsim los rau kev sib dhos vuam txheej txheem ntawm qee qhov vuam sib dhos.Lawv yog cov khoom siv uas tsis yog tus qauv thiab feem ntau yuav tsum tau ua raws li cov yam ntxwv ntawm cov khoom, cov xwm txheej tsim khoom thiab koj qhov xwm txheej tiag tiag.Yuav tsum tau tsim thiab tsim los ntawm koj tus kheej.Vuam fixture tsim yog ib qho ntawm cov ntsiab lus tseem ceeb ntawm kev npaj ntau lawm thiab ib qho ntawm cov dej num tseem ceeb ntawm kev tsim cov txheej txheem vuam tsim.Rau tsheb, maus taus thiab dav hlau Nws tsis yog exaggeration hais tias tsis muaj cov khoom uas tsis muaj vuam tooling.Los ntawm kev ua cov cuab yeej xav tau, cov qauv kos duab thiab cov lus piav qhia luv luv thaum lub sijhawm tsim cov txheej txheem, raws li cov qauv tsim kom tiav thiab cov qauv tsim thiab tag nrho cov duab kos.

Qhov zoo ntawm cov cuab yeej fixture tsim muaj kev cuam tshuam ncaj qha rau kev tsim khoom, tus nqi ua haujlwm, cov khoom zoo thiab kev ruaj ntseg ntau lawm.Vim li no, tsim cov cuab yeej siv vuam yuav tsum xav txog kev ua tau zoo, kev lag luam, thiab kev ntseeg siab, kev ua yeeb yam, thiab lwm yam.

Dimensional chain teeb meem yog muaj nyob rau hauv txhua yam tsim thiab tsim cov txheej txheem.Nyob rau hauv tus txheej txheem ntawm assembling qhov chaw rau hauv cov cav tov, uas yog, combining thiab accumulating lub qhov ntev ntawm cov khoom.Vim yog ib feem me me Muaj kev tsim khoom yuam kev, yog li yuav muaj kev sib koom ua ke thiab sib sau ua ke ntawm qhov yuam kev thaum sib dhos.Tag nrho qhov yuam kev tsim tom qab tsub zuj zuj yuav cuam tshuam rau kev ua haujlwm thiab kev ua haujlwm zoo ntawm lub tshuab.Qhov no tsim ib qho kev ua yuam kev nyob rau hauv ib feem Qhov kev sib raug zoo ntawm kev sib raug zoo nrog kev ua yuam kev.Design fixtures yog tsis muaj kev zam.Nws yog ib qho tseem ceeb rau kev txiav txim siab qhov ntev ntawm qhov kam rau ua thiab geometric tolerances ntawm ib feem.
