Nrog rau kev txhim kho txuas ntxiv ntawm kuv lub teb chaws kev lag luam muaj zog, kev lag luam tshuab tau nce siab dua cov kev xav tau rau cov khoom zoo. Kev ua haujlwm zoo ntawm cov khoom yog lub hauv paus rau kev ua kom cov khoom zoo, thiab cov qauv ntsuas kev ua haujlwm zoo yog kev ua haujlwm raug. Kev ua yuam kev yog yam tsis tuaj yeem zam tau hauv cov txheej txheem machining, xav kom peb tswj cov txheej txheem machining, txheeb xyuas qhov cuam tshuam rau qhov tseeb ntawm machining, thiab tawm tswv yim cov kev daws teeb meem los txo qhov yuam kev thiab yog li txhim kho qhov tseeb machining ntawm qhov chaw.
Phau ntawv no, * Kev Ntsuas thiab Kev Tswj Xyuas Qhov Zoo ntawm Machining Accuracy (Second Edition)*, ua rau cov kws tshaj lij engineering uas muaj feem cuam tshuam txog kev ua haujlwm ntawm machining, lub hauv paus ntawm kev ntsuas tshuab, thiab kev ntsuas qhov tseeb thiab kev tswj xyuas zoo hauv cov txheej txheem machining ntawm cov khoom raug. Nws ua raws li cov qauv tshiab uas tau tshaj tawm hauv lub tebchaws, suav nrog ntau cov qauv tsim khoom raws li qhov ua tau, thiab ua tiav thiab hais txog kev ua tau zoo.
