Cov neeg uas tau koom nrog kev lag luam machining ntau xyoo feem ntau ntsib tias tom qab machining, cov khoom loj tsis tuaj yeem lav thiab tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov duab kos.Feem ntau, peb piav qhia txog qhov tshwm sim no los ntawm kev ua haujlwm yuam kev.Cov khoom scrapping tshwm sim los ntawm machining yuam kev nce tus nqi ntawm lub lag luam.Thaum soj ntsuam qhov ua rau ntawm machining yuam kev, peb feem ntau tuaj yeem kos cov lus xaus tias cov khoom lag luam yog deformed.Yog li ntawd, nyob rau hauv cov txheej txheem ntawm kev ua, yuav ua li cas los tiv thaiv cov khoom deformation tau dhau los ua peb cov teeb meem kev xav.

Nyob rau hauv tus txheej txheem ntawm machining, nws yog ib qho yuav tsum tsis txhob siv cov cuab yeej clamping xws li chuck, vise thiab suction khob.Cov khoom tuaj yeem raug machined tsuas yog tom qab cov khoom yog clamped los ntawm clamps.Txhawm rau kom ntseeg tau tias cov khoom tsis xoob tom qab clamping, lub clamping quab yuam ntawm lub fixture feem ntau yog ntau tshaj qhov txiav quab yuam ntawm machining.Lub clamping deformation ntawm cov khoom sib txawv nrog lub zog clamping.Thaum lub clamping quab yuam loj heev, lub clamping quab yuam ntawm lub fixture tsis xoob, Thaum lub clamp raug tso tawm tom qab cov khoom tiav, cov khoom pib deform.Thaum qee qhov deformation hnyav, nws dhau qhov kev xav tau ntawm kev kos duab.

Kev siv tshuab tsis tsim nyog kuj tseem yuav ua rau cov khoom deformation thiab qhov ntev ntawm kev ua siab ntev.Feem ntau, nyob rau hauv tus txheej txheem ntawm qhov kawg xov, tag nrho cov txheej txheem qhov ntev yuav tsum tau lees tias yuav tsis deformed.Cov txheej txheem nrog deformation yuav tsum tau muab tso ua ntej ua tiav.Qhov niaj zaus clamp deformation, cov khoom siv zog tso tawm thiab lwm yam yuav tsum tau coj mus rau hauv tus account kom tiv thaiv cov khoom deformation tawm ntawm kev ua siab ntev tom qab ua tiav.

Feem ntau, thaum daws qhov teeb meem ntawm fixture deformation, tus kws tshaj lij yuav tsim tshwj xeeb fixture, kos cov khoom ua ntej ua, xyuas cov firmness thiab tshuav nyiaj li cas ntawm fixture, qhov sib txawv thiab txawv clamping txoj kev, thiaj li yuav txo tau clamping deformation kom deb li deb tau.Nyob rau tib lub sijhawm, kuj sim zam, kev ua haujlwm ncua ntev ntev, txhawm rau ua kom cov khoom lag luam hauv cov txheej txheem ua haujlwm viav vias deformation.

Nyob rau hauv tus txheej txheem ntawm machining nyias-walled qhov chaw, cov cuab yeej txiav nrog loj rake lub kaum sab xis kuj yuav txo tau lub txiav quab yuam thiab lub rake lub kaum sab xis.
