Yog vim li cas vim li cas lub sawing workpiece tsis ntsug thiab qhov ntev yog inconsistent:

1. Kev sib tsoo thiab kev sib tsoo ntawm lub thav duab pub mis thaum txiav, qhov chaw tsis raug, thiab lub tshuab tsis calibrated thaum nws sib sau ua ke.

2. Siv cov saw hniav uas deformed nyob rau hauv siab

3. Lub deformation ntawm cov khoom txiav tsis yog tus qauv

4. Cov cuab yeej txiav ntawm lub tshuab yog ceev heev thiab cov hniav tsis raug

Kev daws:

1. Nquag xyuas cov khoom ntawm cov khoom khib nyiab thiab cov kav dej, thiab kho cov qib ntawm lub tshuab

2. Vim hais tias cov saw hniav muaj ib tug sag, nws yuav tsum tau txhim tsa thiab muab tso rau kom tsis txhob muaj lub siab ntawm lub ntiajteb txawj nqus.

3. Xaiv cov khoom zoo thiab cov khoom siv txheem.

4. Xaiv qhov raug txiav ceev raws li cov ntaub ntawv sib txawv, thiab xaiv tus naj npawb ntawm cov hniav raws li phab ntsa thickness ntawm cov khoom.
