Nyob rau hauv ntau lawm, qhov yooj yim tshaj plaws deformation ntawm elastic nyias phaj qhov kev soj ntsuam, pom tias cov machining tseeb tau tag nrho cov txheej txheem tsim, tab sis pom qhov loj thiab cov duab ntawm lub siab ntev tom qab deletion, zoo hloov tau coj qhov chaw, deb tshaj qhov tau ntawm kev tsim. Vim li cas: tsis yooj yim deformation thiab rigidity ntawm tivthaiv nyias cov ntaub ntawv nyias muaj tseeb tsis yog siab, pluag smoothness, compression artifacts yog tshwm sim los ntawm qhov atmospheric siab los yog ceev nruj suction zog, xws li clamping quab yuam los ntawm kev deformation ntawm lub workpiece, tej kev ua haujlwm, txawm hais tias kev lag luam ntawm kev ua haujlwm me me, cov qauv thiab kev ua haujlwm kam ua tau raws li cov qauv tsim, tabsis cia ua haujlwm ntawm kev ua haujlwm deformation, nws loj thiab zoo siab, kev hloov loj muaj qhov chaw, ntau tshaj li qhov uas yuav tsum tau ua.
Kuaj lwm qhov ntawm qhov yoojyim deformation ntawm cov ntaub ntawv tseem ceeb ntawm cov ntaub ntawv nyias yeem, pom tias qhov loj me, daim ntawv thiab kev kam rau ua haujlwm ntawm workpiece thiab tshuab cuab yeej ua haujlwm ntawm qhov qub, qhov no yog vim hais tias qhov workpiece hauv kev txiav quab yuam hauv lub deformation ntawm Cheebtsam, nyob rau pem hauv ntej, ua kom lub cev deformation.
Yog li, nws yog ib qho tseem ceeb ntsuas los txhim kho qhov kev txiav txim siab ntawm qhov chaw, txo cov clamping deformation thiab txo quab yuam.
