1:Kev sib tsoo taw tes kub yog siab heev, lub luag hauj lwm ntawm kev sib tsoo yog nqus cov cua sov thaum sib tsoo kom sai li sai tau, thiaj li hais tias lub workpiece kub poob, los tiv thaiv lub deterioration ntawm cov txheej txheem deg lub xeev. Lub machining zoo ntawm lub workpiece raug cuam tshuam. Cov nyhuv txias yog nyob ntawm qhov thermal conductivity, lub peev xwm kub tshwj xeeb, cua sov ntawm vaporization, vaporization ceev, kua ntws tus nqi thiab tshaj tawm ntawm cov dej sib tsoo.
2:Lub luag haujlwm ntawm cov kua dej sib tsoo yog tswj xyuas lub xeev kev sib tsoo kom deb li deb tau, txo qhov hnav thiab passivation ntawm cov khoom abrasive, txuas lub durability ntawm lub log sib tsoo, tuav qhov tseeb qhov tseeb, thiab tiv thaiv qhov deterioration ntawm machined nto roughness. . Yog li ntawd, cov dej sib tsoo yuav tsum tsis yog tsuas yog ua kom muaj cua txias xwb, tab sis kuj muaj lubrication, tu, tiv thaiv xeb thiab lwm yam haujlwm.
3:Nyob rau hauv txoj kev sib tsoo, vim qhov kub ntawm qhov chaw sib tsoo, cov dej sib tsoo yog ib nrab boiled thiab vaporized nyob rau lub sijhawm no. Lub vaporization ntawm cov kua sib tsoo absorbs ib tug loj npaum li cas ntawm tshav kub, uas yog hu ua lub tshav kub ntawm vaporization. Vim tias cov cua sov nqus los ntawm vaporization yog qhov loj tshaj plaws, thaum siv cov khoom sib tsoo, cov xwm txheej (xws li tshuaj tsuag) yuav tsum tau tsim kom deb li deb tau kom nws yooj yim rau vaporize.
