Hmoov txau siv cov qauv ntawm kev sib nrig sib xyaw thiab tsis zoo cov hmoov av sib xyaw, thiab kom cov khoom siv hluav taws xob sib xyaw ua ke los ua cov txheej kub tuab - nplaim ntawm workpiece. Tawm thev naus laus zis. Vim yog lub tshuab hluav taws xob kom txau cov hmoov txau cov khoom, tsis muaj cov microscores, tsis muaj cov microsating, thiab cov hluav taws xob zoo nkauj thiab hluav taws xob thiab lwm yam. Cov tsos Zoo heev tshaj li ntawm cov tshuaj tsuag ib txwm muaj tshuaj pleev xim, txheej txheem xim.
Tsis tas li ntawd, cov khoom siv txheej hmoov ua rau cov khoom tsis tsuas yog du, tawv, thiab tseem muaj cov yam ntxwv ntawm kev xaiv xim arbedrary. Tsis tas li ntawd, cov hmoov txau hluav taws xob cov khoom siv tau txau thev naus laus zis, uas tuaj yeem tau txais cov txiaj ntsig txaus siab nrog tsuas yog ib qho kev ua haujlwm nkaus xwb. Yog li ntawd, kev ua haujlwm tsim tau tuaj yeem txhim kho kom zoo dua qub thiab tus nqi tuaj yeem raug txo qis; Thiab vim tias cov hmoov hmoov tsis muaj cov kuab tshuaj, cov hmoov ntau dhau tuaj yeem rov siv dua thiab siv cov pa phem ib puag ncig, thiab cov pa phem ib puag ncig yog zam.
