Nyob rau hauv layman' s cov nqe lus, cov txheej txheem txoj kev hais txog tag nrho cov txheej txheem uas tag nrho ib feem yuav tsum tau mus los ntawm qhov dawb paug mus rau cov khoom tiav. Lub formulation ntawm cov txheej txheem txoj kev yog ib qho tseem ceeb cov ntsiab lus ntawm precision machining txheej txheem. Lub luag haujlwm tseem ceeb yog txiav txim siab tus lej thiab cov ntsiab lus ntawm cov txheej txheem, thiab xaiv txhua ntu. Txoj kev ua deg, txiav txim siab ua ntu zus ntawm txhua qhov chaw, thiab lwm yam.
Qhov sib txawv tseem ceeb ntawm cov txheej txheem tsim ntawm CNC machining thiab cov cuab yeej siv tshuab zoo tib yam yog qhov qub tsis yog tag nrho cov txheej txheem los ntawm qhov khoob mus rau cov khoom tiav, tab sis tsuas yog ib qho kev piav qhia ntawm cov txheej txheem ntawm ntau cov txheej txheem CNC machining. Hauv CNC precision machining, CNC machining cov txheej txheem feem ntau cuam tshuam nrog cov khoom. Nyob rau hauv tag nrho cov txheej txheem ntawm kev ua, nws yuav tsum muaj kev sib raug zoo nrog rau lwm cov txheej txheem ua. Qhov no yog qhov chaw yuav tsum tau them sai sai rau hauv cov txheej txheem tsim.
